## Introduction

This guide walks you through connecting Apollo to Mastra AI using the Composio tool router. By the end, you'll have a working Apollo agent that can bulk enrich profiles for new leads, add contacts to outreach sequence now, create a new sales deal for acme through natural language commands.
This guide will help you understand how to give your Mastra AI agent real control over a Apollo account through Composio's Apollo MCP server.
Before we dive in, let's take a quick look at the key ideas and tools involved.

## TL;DR

Here's what you'll learn:
- Set up your environment so Mastra, OpenAI, and Composio work together
- Create a Tool Router session in Composio that exposes Apollo tools
- Connect Mastra's MCP client to the Composio generated MCP URL
- Fetch Apollo tool definitions and attach them as a toolset
- Build a Mastra agent that can reason, call tools, and return structured results
- Run an interactive CLI where you can chat with your Apollo agent

## What is Mastra AI?

Mastra AI is a TypeScript framework for building AI agents with tool support. It provides a clean API for creating agents that can use external services through MCP.
Key features include:
- MCP Client: Built-in support for Model Context Protocol servers
- Toolsets: Organize tools into logical groups
- Step Callbacks: Monitor and debug agent execution
- OpenAI Integration: Works with OpenAI models via @ai-sdk/openai

## What is the Apollo MCP server, and what's possible with it?

The Apollo MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Apollo account. It provides structured and secure access to your CRM and lead generation data, so your agent can create contacts, enrich organizations, manage deals, update account stages, and automate tasks for your sales pipeline—all on your behalf.
- Contact and account creation: Instantly add new contacts or accounts to Apollo, linking them to organizations and stages to keep your CRM up to date with zero manual entry.
- Bulk data enrichment: Rapidly enrich multiple people or organizations at once, leveraging Apollo's database to fill gaps and update your records with the latest information.
- Sales opportunity and pipeline management: Let your agent create new deals, retrieve opportunity stages, and move accounts through your sales funnel to optimize pipeline performance.
- Automated outreach sequencing: Add contacts to email sequences, making it easy to launch targeted campaigns and follow-ups without lifting a finger.
- Task creation and label organization: Generate actionable Apollo tasks for your team and organize contacts or accounts with labels, so nothing slips through the cracks.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `APOLLO_ADD_CONTACTS_TO_SEQUENCE` | Add Contacts to Sequence | Adds contacts to a specified Apollo email sequence and returns the contact details. `sequence_id`, `emailer_campaign_id`, and `send_email_from_email_account_id` must be retrieved from Apollo listing/search endpoints before calling this tool — these IDs cannot be inferred from names. |
| `APOLLO_BULK_ORGANIZATION_ENRICHMENT` | Bulk organization enrichment | Enriches data for up to 10 organizations simultaneously by providing a list of their base company domains (e.g., 'apollo.io', not 'www.apollo.io'). Each call consumes Apollo credits per domain enriched; monitor quota to avoid exhaustion errors. |
| `APOLLO_BULK_PEOPLE_ENRICHMENT` | Bulk people enrichment | Use to enrich multiple person profiles simultaneously with comprehensive data from Apollo's database. Each call consumes Apollo credits; avoid re-enriching the same contacts. Responses may include null or missing fields (e.g., email, phone, organization); treat unmatched records as valid 'no match' outcomes, not errors. Heavy use may trigger HTTP 429; respect Retry-After headers. |
| `APOLLO_BULK_UPDATE_ACCOUNT_STAGE` | Bulk update account stage | Bulk updates the stage for specified existing Apollo.io accounts, moving them to a valid new account stage. |
| `APOLLO_CREATE_ACCOUNT` | Create an Apollo account | Creates a new account in Apollo.io; a new record is created even if a similar account exists, and provided `owner_id` or `account_stage_id` must be valid existing IDs. The response includes the new account's ID, which can be used directly in subsequent calls. |
| `APOLLO_CREATE_BULK_ACCOUNTS` | Bulk create Apollo accounts | Creates multiple accounts in Apollo.io with a single API call (maximum 100 accounts per request). Use when creating multiple company records at once. |
| `APOLLO_CREATE_BULK_CONTACTS` | Bulk create Apollo contacts | Tool to bulk create multiple contacts in Apollo with a single API call. Use when you need to create multiple contacts efficiently. Supports up to 100 contacts per request with optional deduplication. |
| `APOLLO_CREATE_CALL_RECORD` | Create call record in Apollo | Tool to log call records in Apollo from external systems. Use when recording calls made through outside systems like Orum or Nooks; requires a master API key and cannot dial prospects directly. |
| `APOLLO_CREATE_CONTACT` | Create Apollo contact | Creates a new contact in Apollo.io; use `account_id` to link to an organization and `contact_stage_id` for sales stage. Apollo does not auto-deduplicate — duplicate records sharing the same email are silently created; always search via APOLLO_SEARCH_CONTACTS before calling this tool. Requires explicit user confirmation before execution. |
| `APOLLO_CREATE_CUSTOM_FIELD` | Create custom field | Creates a new custom field in Apollo.io for contacts, accounts, or opportunities. Use when you need to define additional data fields beyond Apollo's standard attributes. |
| `APOLLO_CREATE_DEAL` | Create Apollo deal | Creates a new sales opportunity (deal) in Apollo.io; all provided IDs (`owner_id`, `account_id`, `opportunity_stage_id`) must be valid existing Apollo identifiers. This action has persistent side effects — obtain explicit user confirmation before invoking. |
| `APOLLO_CREATE_TASK` | Create Apollo Task | Tool to create a single task in Apollo.io. Use when you need to add a new task to your team's Apollo account for a specific contact. The task will be assigned to a user and includes details like type, status, priority, due date, and optional notes. |
| `APOLLO_GET_ACCOUNT` | Get Account by ID | Tool to retrieve detailed information about a specific account by its Apollo ID. Use when you need to fetch complete account data including company details, contact information, and CRM integration fields. |
| `APOLLO_GET_AUTH_STATUS` | Check Apollo API key status | Tool to check whether the provided Apollo API key is valid and accepted by Apollo (health/auth check). Use when any Apollo endpoint returns 401/403/422 to quickly diagnose invalid/expired keys versus permission scope issues. If this succeeds but other endpoints return 403, it strongly suggests permissioning or master-key scope issues rather than a totally invalid credential. |
| `APOLLO_GET_CONTACT` | Get Apollo Contact | Retrieves detailed information about a specific contact by its ID. Use this to view contact details including name, email, phone numbers, organization, and custom fields. |
| `APOLLO_GET_DEAL` | Get Apollo deal | Retrieves information about a specific deal by its ID. Use this when you need to view details of a single deal. |
| `APOLLO_GET_LABELS` | Get Labels | Retrieves all labels from Apollo.io, used for organizing contacts and accounts. Call this before APOLLO_CREATE_CONTACT or APOLLO_UPDATE_ACCOUNT to validate label values against the returned list; mismatched labels cause 400/422 errors. |
| `APOLLO_GET_OPPORTUNITY_STAGES` | Get opportunity stages | Retrieves all configured opportunity (deal) stages from the Apollo.io account. |
| `APOLLO_GET_ORGANIZATION` | Get Organization by ID | Retrieves complete information about a specific organization by its Apollo ID. Use when you need detailed company data including funding, technologies, employee counts, and more. |
| `APOLLO_GET_ORGANIZATION_JOB_POSTINGS` | Get Organization Job Postings | Retrieves paginated job postings for a specified organization by its ID, optionally filtering by domain; ensure `organization_id` is a valid identifier. |
| `APOLLO_GET_TYPED_CUSTOM_FIELDS` | Get typed custom fields | Retrieves all typed custom field definitions available in the Apollo.io instance, detailing their types and configurations. Call before constructing payloads for APOLLO_UPDATE_CONTACT or APOLLO_UPDATE_ACCOUNT — mismatched types or invalid enum options cause 400 errors. |
| `APOLLO_LIST_ACCOUNT_STAGES` | List Apollo account stages | Retrieves the IDs for all available account stages in your team's Apollo account. |
| `APOLLO_LIST_CONTACT_STAGES` | List apollo contact stages | Retrieves all available contact stages from an Apollo account, including their unique IDs and names. |
| `APOLLO_LIST_DEALS` | List Apollo deals | Retrieves a list of deals from Apollo, using Apollo's default sort order if 'sort_by_field' is omitted. |
| `APOLLO_LIST_EMAIL_ACCOUNTS` | List email accounts | Retrieves all email accounts and their details for the authenticated user; takes no parameters. |
| `APOLLO_LIST_FIELDS` | List Fields | Retrieves all field definitions from Apollo.io, including system fields and custom fields. Use the optional 'source' parameter to filter by field type (system, custom, or crm_synced). |
| `APOLLO_LIST_USERS` | List Apollo Users | Retrieves a list of all users (teammates) associated with the Apollo account, supporting pagination via `page` and `per_page` parameters. Use this to obtain numeric user IDs required by operations like APOLLO_UPDATE_CONTACT_OWNERSHIP — names or email addresses are not accepted in place of these IDs. |
| `APOLLO_ORGANIZATION_ENRICHMENT` | Enrich organization data | Fetches comprehensive organization enrichment data from Apollo.io for a given company domain; results are most meaningful if the company exists in Apollo's database. Each call consumes Apollo credits and may be unavailable on free plans. Returns HTTP 429 under burst usage; use exponential backoff on retries. |
| `APOLLO_ORGANIZATION_SEARCH` | Search organizations in Apollo | Searches Apollo's database for organizations using various filters; consumes credits on every call (unavailable on free plans) — avoid re-running identical queries and surface quota errors rather than retrying. Retrieves a maximum of 50,000 records; uses `page` (1-500) and `per_page` (1-100) for pagination — check `total_pages` in the response to iterate. Overly strict filter combinations can return zero results; start broad and narrow iteratively. Empty results and `org_not_found` are valid outcomes, not errors. |
| `APOLLO_PEOPLE_ENRICHMENT` | Enrich person with Apollo | Enriches and retrieves information for a person from Apollo.io. Requires one of: `id`, `email`, `hashed_email`, `linkedin_url`, or (`first_name` and `last_name` with `organization_name` or `domain`) for matching. `webhook_url` must be provided if `reveal_phone_number` is true. Name-only inputs without `organization_name` or `domain` frequently return no matches. |
| `APOLLO_PEOPLE_SEARCH` | Apollo people search | Searches Apollo's contact database for people using various filters; results capped at 50,000 records and does not enrich contact data. Combining multiple strict filters (organization_ids, person_titles, person_seniorities) can return zero results — start broad and narrow iteratively. Result records may have null email, phone, or organization fields. |
| `APOLLO_SEARCH_ACCOUNTS` | Search Apollo Accounts | Searches for accounts within your existing Apollo.io database using various criteria; requires a paid plan and is limited to 50,000 records. |
| `APOLLO_SEARCH_CALLS` | Search for Calls | Searches for call records in Apollo.io using filters like date range, duration, direction (inbound/outgoing), users, contacts, purposes, outcomes, and keywords. Supports pagination for efficient data retrieval. |
| `APOLLO_SEARCH_CONTACTS` | Search Apollo contacts | Searches Apollo contacts using keywords, stage IDs (from 'List Contact Stages' action), or sorting (max 50,000 records; `sort_ascending` requires `sort_by_field`). Search before creating contacts to avoid duplicates. |
| `APOLLO_SEARCH_NEWS_ARTICLES` | Search news articles | Tool to search for news articles about companies in Apollo's database. Use when you need to find recent news, announcements, or updates about specific organizations using their Apollo IDs. |
| `APOLLO_SEARCH_OUTREACH_EMAILS` | Search outreach emails | Tool to search for outreach emails sent through Apollo sequences. Use when you need to find emails created and sent by your team as part of Apollo email campaigns. This endpoint requires a master API key and has a display limit of 50,000 records (100 records per page, up to 500 pages). |
| `APOLLO_SEARCH_SEQUENCES` | Search sequences | Searches for sequences (e.g., automated email campaigns) in Apollo.io. |
| `APOLLO_SEARCH_TASKS` | Search tasks | Searches for tasks in Apollo.io using filters like keywords, date ranges (due, created, updated), priorities, types, assigned users, associated contacts/accounts, supporting sorting and pagination. |
| `APOLLO_UPDATE_ACCOUNT` | Update an Apollo account | Updates specified attributes of an existing account in Apollo.io. |
| `APOLLO_UPDATE_ACCOUNT_OWNERS` | Update account ownership | Updates the ownership of multiple Apollo accounts to a specified user. Use when bulk assigning account ownership to a team member. |
| `APOLLO_UPDATE_CALL_RECORD` | Update Apollo call record | Tool to update an existing call record in Apollo.io. Use when you need to modify details of a previously logged phone call such as duration, status, notes, or associated contact/account information. |
| `APOLLO_UPDATE_CONTACT` | Update Apollo contact details | Tool to update an existing contact's information in Apollo. Use when you need to modify contact details such as name, email, phone, title, organization, or custom fields. At least one field beyond contact_id must be provided. |
| `APOLLO_UPDATE_CONTACT_OWNERSHIP` | Update contact ownership | Updates the ownership of specified Apollo contacts to a given Apollo user, who must be part of the same team. |
| `APOLLO_UPDATE_CONTACTS_BULK` | Bulk update Apollo contacts | Tool to bulk update multiple Apollo contacts with a single API call. Use when updating multiple contacts simultaneously - either apply the same updates to all contacts using contact_ids, or apply different updates to each contact using contact_attributes. Automatically processes asynchronously for more than 100 contacts. |
| `APOLLO_UPDATE_CONTACT_STAGE` | Update contact stage | Updates the stage for one or more existing contacts in Apollo.io to a new valid contact stage, useful for managing sales funnel progression. |
| `APOLLO_UPDATE_CONTACT_STATUS_IN_SEQUENCE` | Update contact status in sequence | Updates a contact's status within a designated Apollo sequence, but cannot set the status to 'active'. |
| `APOLLO_UPDATE_DEALS` | Update Apollo deal | Updates specified fields of an existing Apollo.io deal (opportunity), requiring a valid `opportunity_id`. |
| `APOLLO_VIEW_API_USAGE_STATS` | View API Usage Stats | Fetches Apollo API usage statistics and rate limits for the connected team. Use before large enrichment/search runs to understand current API usage and plan/budget constraints. If experiencing 403s on credit/usage sensitive endpoints, use this tool to confirm whether the key has master privileges (this endpoint will 403 without a master key). |

## Creating MCP Server - Stand-alone vs Composio SDK

The Apollo MCP server is an implementation of the Model Context Protocol that connects your AI agent to Apollo. It provides structured and secure access so your agent can perform Apollo operations on your behalf through a secure, permission-based interface.
With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster.

## Step-by-step Guide

### 1. Prerequisites

Before starting, make sure you have:
- Node.js 18 or higher
- A Composio account with an active API key
- An OpenAI API key
- Basic familiarity with TypeScript

### 1. Getting API Keys for OpenAI and Composio

OpenAI API Key
- Go to the [OpenAI dashboard](https://platform.openai.com/settings/organization/api-keys) and create an API key.
- You need credits or a connected billing setup to use the models.
- Store the key somewhere safe.
Composio API Key
- Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs).
- Go to Settings and copy your API key.
- This key lets your Mastra agent talk to Composio and reach Apollo through MCP.

### 2. Install dependencies

Install the required packages.
What's happening:
- @composio/core is the Composio SDK for creating MCP sessions
- @mastra/core provides the Agent class
- @mastra/mcp is Mastra's MCP client
- @ai-sdk/openai is the model wrapper for OpenAI
- dotenv loads environment variables from .env
```bash
npm install @composio/core @mastra/core @mastra/mcp @ai-sdk/openai dotenv
```

### 3. Set up environment variables

Create a .env file in your project root.
What's happening:
- COMPOSIO_API_KEY authenticates your requests to Composio
- COMPOSIO_USER_ID tells Composio which user this session belongs to
- OPENAI_API_KEY lets the Mastra agent call OpenAI models
```bash
COMPOSIO_API_KEY=your_composio_api_key_here
COMPOSIO_USER_ID=your_user_id_here
OPENAI_API_KEY=your_openai_api_key_here
```

### 4. Import libraries and validate environment

What's happening:
- dotenv/config auto loads your .env so process.env.* is available
- openai gives you a Mastra compatible model wrapper
- Agent is the Mastra agent that will call tools and produce answers
- MCPClient connects Mastra to your Composio MCP server
- Composio is used to create a Tool Router session
```typescript
import "dotenv/config";
import { openai } from "@ai-sdk/openai";
import { Agent } from "@mastra/core/agent";
import { MCPClient } from "@mastra/mcp";
import { Composio } from "@composio/core";
import * as readline from "readline";

import type { AiMessageType } from "@mastra/core/agent";

const openaiAPIKey = process.env.OPENAI_API_KEY;
const composioAPIKey = process.env.COMPOSIO_API_KEY;
const composioUserID = process.env.COMPOSIO_USER_ID;

if (!openaiAPIKey) throw new Error("OPENAI_API_KEY is not set");
if (!composioAPIKey) throw new Error("COMPOSIO_API_KEY is not set");
if (!composioUserID) throw new Error("COMPOSIO_USER_ID is not set");

const composio = new Composio({
  apiKey: composioAPIKey as string,
});
```

### 5. Create a Tool Router session for Apollo

What's happening:
- create spins up a short-lived MCP HTTP endpoint for this user
- The toolkits array contains "apollo" for Apollo access
- session.mcp.url is the MCP URL that Mastra's MCPClient will connect to
```typescript
async function main() {
  const session = await composio.create(
    composioUserID as string,
    {
      toolkits: ["apollo"],
    },
  );

  const composioMCPUrl = session.mcp.url;
  console.log("Apollo MCP URL:", composioMCPUrl);
```

### 6. Configure Mastra MCP client and fetch tools

What's happening:
- MCPClient takes an id for this client and a list of MCP servers
- The headers property includes the x-api-key for authentication
- getTools fetches the tool definitions exposed by the Apollo toolkit
```typescript
const mcpClient = new MCPClient({
    id: composioUserID as string,
    servers: {
      nasdaq: {
        url: new URL(composioMCPUrl),
        requestInit: {
          headers: session.mcp.headers,
        },
      },
    },
    timeout: 30_000,
  });

console.log("Fetching MCP tools from Composio...");
const composioTools = await mcpClient.getTools();
console.log("Number of tools:", Object.keys(composioTools).length);
```

### 7. Create the Mastra agent

What's happening:
- Agent is the core Mastra agent
- name is just an identifier for logging and debugging
- instructions guide the agent to use tools instead of only answering in natural language
- model uses openai("gpt-5") to configure the underlying LLM
```typescript
const agent = new Agent({
    name: "apollo-mastra-agent",
    instructions: "You are an AI agent with Apollo tools via Composio.",
    model: "openai/gpt-5",
  });
```

### 8. Set up interactive chat interface

What's happening:
- messages keeps the full conversation history in Mastra's expected format
- agent.generate runs the agent with conversation history and Apollo toolsets
- maxSteps limits how many tool calls the agent can take in a single run
- onStepFinish is a hook that prints intermediate steps for debugging
```typescript
let messages: AiMessageType[] = [];

console.log("Chat started! Type 'exit' or 'quit' to end.\n");

const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout,
  prompt: "> ",
});

rl.prompt();

rl.on("line", async (userInput: string) => {
  const trimmedInput = userInput.trim();

  if (["exit", "quit", "bye"].includes(trimmedInput.toLowerCase())) {
    console.log("\nGoodbye!");
    rl.close();
    process.exit(0);
  }

  if (!trimmedInput) {
    rl.prompt();
    return;
  }

  messages.push({
    id: crypto.randomUUID(),
    role: "user",
    content: trimmedInput,
  });

  console.log("\nAgent is thinking...\n");

  try {
    const response = await agent.generate(messages, {
      toolsets: {
        apollo: composioTools,
      },
      maxSteps: 8,
    });

    const { text } = response;

    if (text && text.trim().length > 0) {
      console.log(`Agent: ${text}\n`);
        messages.push({
          id: crypto.randomUUID(),
          role: "assistant",
          content: text,
        });
      }
    } catch (error) {
      console.error("\nError:", error);
    }

    rl.prompt();
  });

  rl.on("close", async () => {
    console.log("\nSession ended.");
    await mcpClient.disconnect();
    process.exit(0);
  });
}

main().catch((err) => {
  console.error("Fatal error:", err);
  process.exit(1);
});
```

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Apollo MCP?

With a standalone Apollo MCP server, the agents and LLMs can only access a fixed set of Apollo tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Apollo and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Mastra AI?

Yes, you can. Mastra AI fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Apollo tools.

### Can I manage the permissions and scopes for Apollo while using Tool Router?

Yes, absolutely. You can configure which Apollo scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Apollo data and credentials are handled as safely as possible.
