SETUP GUIDE

Connect PromptHub MCP Tool with your Agent

1

Install Composio

typescript
npm install @composio/core ai @ai-sdk/mcp @ai-sdk/openai
Install the Composio SDK and your agent framework
2

Create a session with MCP enabled

typescript
import { Composio } from "@composio/core";

const composio = new Composio();
const { mcp } = await composio.create("your-user-id", {
  toolkits: ["prompt_hub"],
  mcp: true,
});
Create a session scoped to PromptHub and read its MCP URL and headers
3

Connect your agent to the MCP server

typescript
import { createMCPClient } from "@ai-sdk/mcp";
import { openai } from "@ai-sdk/openai";
import { generateText, stepCountIs } from "ai";

const client = await createMCPClient({
  transport: { type: "http", url: mcp.url, headers: mcp.headers },
});

const { text } = await generateText({
  model: openai("gpt-5.6-sol"),
  tools: await client.tools(),
  prompt: "Retrieve the latest production version of my PromptHub prompt named customer-support-agent and show its variables",
  stopWhen: stepCountIs(10),
});

console.log(text);
await client.close();
Pass the session's MCP URL and headers to your agent and run a PromptHub request
SETUP GUIDE

Connect PromptHub API Tool with your Agent

1

Install Composio

typescript
npm install @composio/core @composio/openai openai
Install the Composio SDK, the OpenAI provider, and the OpenAI SDK
2

Create a Composio session

typescript
import OpenAI from "openai";
import { Composio } from "@composio/core";
import { OpenAIResponsesProvider } from "@composio/openai";

const composio = new Composio({ provider: new OpenAIResponsesProvider() });
const client = new OpenAI();

const session = await composio.create("your-user-id", { toolkits: ["prompt_hub"] });
const tools = await session.tools();
Initialize Composio with the OpenAI Responses provider and create a session scoped to PromptHub
3

Run PromptHub tools with your agent

typescript
let response = await client.responses.create({
  model: "gpt-5.6-sol",
  tools,
  input: [{ role: "user", content: "Retrieve the latest production version of my PromptHub prompt named customer-support-agent and show its variables" }],
});

while (response.output.some((o) => o.type === "function_call")) {
  const outputs = await composio.provider.handleToolCalls(session, response.output);
  response = await client.responses.create({
    model: "gpt-5.6-sol",
    tools,
    previous_response_id: response.id,
    input: outputs,
  });
}

console.log(response.output_text);
Send a request, execute the PromptHub tool calls through the session, and print the final answer

Why Use Composio?

AI Native PromptHub Integration

  • Supports both PromptHub MCP and direct API based integrations
  • Structured, LLM-friendly schemas for reliable prompt retrieval and execution
  • Rich coverage for reading, running, and querying your PromptHub prompt library

Managed Auth

  • Bring your PromptHub API key and connect it with auth_configs.create()
  • Link user access with connected_accounts.link() instead of hard-coding keys in agent code
  • Composio handles secure credential storage and API request handling for PromptHub

Agent Optimized Design

  • Tools are shaped so agents can understand PromptHub prompts, versions, and execution inputs clearly
  • Execution logs show which prompt was fetched or run, when it happened, and on whose behalf
  • Create MCP sessions with mcp.create() so Claude, Cursor, and other MCP clients can use PromptHub naturally

Enterprise Grade Security

  • Fine-grained RBAC so you control which agents and users can access PromptHub
  • Scoped, least privilege access to PromptHub prompt resources
  • Full audit trail of agent actions to support review, rollback, and compliance
FAQ

Frequently asked questions

Yes, PromptHub requires you to configure your own API key credentials. Once set up, Composio handles secure credential storage and API request handling for you. You can create the auth config with auth_configs.create(), link users with connected_accounts.link(), and expose PromptHub over MCP with mcp.create().

Yes! Composio's Tool Router enables agents to use multiple toolkits. Learn more.

Yes. Composio is SOC 2 Type II compliant and is built to keep your PromptHub connection and credentials secure. OAuth tokens and API keys are encrypted, and sensitive customer data is protected at rest and in transit.

Composio also undergoes independent security testing and continuously monitors its systems for security threats. You can review the latest reports and policies in the Composio Trust Center.

Composio maintains and updates all toolkit integrations automatically, so your agents always work with the latest API versions.

Create the key in your PromptHub account settings, then paste it once on Composio's connection page. Composio stores it encrypted and uses it only for the PromptHub actions your agent runs. Nobody else in your workspace can read it, and you can revoke it inside PromptHub at any time.

When you connect a PromptHub account through Composio, every action runs under that account, so anything the agent creates, sends, or changes shows up in PromptHub as done by you. Keep an approval step in your prompt for actions with side effects, such as sending or deleting, and have the agent draft first.

Whatever the credentials you connect allow inside PromptHub. If PromptHub lets you scope a key to specific permissions, create a scoped one so the agent can only do what you intend. You can revoke the key inside PromptHub at any time.

Yes. Composio supports multiple connected accounts for the same app, and that works in Claude, ChatGPT, or any other assistant you connect through Composio. Give each PromptHub connection a name such as work or personal, and the assistant uses the one you mention in the request. Each account keeps its own credentials and nothing is merged.

The connection stops working the moment PromptHub rejects the old key. Create a new key in PromptHub and reconnect the account from the Composio dashboard or by asking your agent to reconnect PromptHub. Nothing else changes.

Composio's free Hobby plan includes 100,000 tool calls per month with no credit card, which covers most personal PromptHub use. Paid plans add higher limits and team features. Your PromptHub plan and its API limits still apply as usual.

Built-in connectors usually give one AI access to a limited set of apps. Many people use Composio because it lets their AI connect to more apps than it normally supports, or connect to multiple accounts for the same app (e.g. connect Claude to multiple PromptHub accounts).

With Composio, you connect PromptHub once and then use it across different AI assistants without setting it up separately in each one. Connect your apps to Composio once, then connect Composio to whichever AI you use, whether that's Claude, ChatGPT, Hermes, or your own custom assistant.
