Grok MCP server for AI agents and assistants

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with Grok MCP or direct API to generate text, analyze images, create embeddings, run search, and process files through natural language.

Api Key

Grok is xAI's API platform for text, image, video, embeddings, files, search, and voice. Use it to add fast multimodal AI capabilities from xAI to apps and workflows.

TOOLS

Supported Tools

Every Grok action and event your agent gets out of the box.

Create Embeddings

Create vector embeddings for one or more text inputs with an xAI embedding model.

Create Response

Generate a bounded, non-streaming Grok response from text or structured multimodal input, with optional reasoning, search, and function or web-search tools.

Generate Image

Generate one or more images from a text prompt with an xAI image-generation model.

Generate Video

Start asynchronous xAI video generation from a text prompt, optionally conditioned on an image, and return a request ID for status checks.

Get API Key Info

Inspect the connected xAI API key's identity, wildcard or granular ACLs, and key or team blocking state.

Get Current Account

Verify the connected xAI credential and return the caller, team, zero-data-retention status, and key blocking state.

Get Video

Check an asynchronous xAI video request.

List Models

List models available to the connected xAI key, including model IDs and published pricing metadata needed to choose a model for other tools.

SETUP GUIDE

Connect Grok 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: ["grok"],
  mcp: true,
});
Create a session scoped to Grok 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: "Use Grok to generate a concise product launch brief for a new AI coding assistant",
  stopWhen: stepCountIs(10),
});

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

Connect Grok 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: ["grok"] });
const tools = await session.tools();
Initialize Composio with the OpenAI Responses provider and create a session scoped to Grok
3

Run Grok tools with your agent

typescript
let response = await client.responses.create({
  model: "gpt-5.6-sol",
  tools,
  input: [{ role: "user", content: "Use Grok to generate a concise product launch brief for a new AI coding assistant" }],
});

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 Grok tool calls through the session, and print the final answer

Why Use Composio?

AI Native Grok Integration

  • Supports both Grok MCP and direct API based integrations
  • Structured, LLM-friendly schemas for reliable text, vision, embedding, search, and voice tool execution
  • Rich coverage for building agents that can call xAI capabilities without bespoke integration code

Managed API Key Auth

  • Securely store Grok API keys instead of hard-coding them into agent code
  • Central place to manage, scope, and revoke Grok access across users and environments
  • Composio handles credential storage and API request handling so your agents can focus on the task

Agent Optimized Design

  • Grok tools are exposed with clear schemas that language models can understand and call reliably
  • Tools are tuned using real error and success rates to improve reliability over time
  • Comprehensive execution logs so you always know what ran, when, and on whose behalf

Enterprise Grade Security

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

Frequently asked questions

Yes, Grok requires you to configure your own API key. Once set up, Composio handles secure credential storage and API request handling for you. You can create an auth config with auth_configs.create(), connect a user with connected_accounts.link(), and expose Grok to agents through mcp.create() or a Tool Router session.

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

When you connect a Grok account through Composio, every action runs under that account, so anything the agent creates, sends, or changes shows up in Grok 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 Grok. If Grok 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 Grok 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 Grok 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 Grok rejects the old key. Create a new key in Grok and reconnect the account from the Composio dashboard or by asking your agent to reconnect Grok. Nothing else changes.

Composio's free Hobby plan includes 100,000 tool calls per month with no credit card, which covers most personal Grok use. Paid plans add higher limits and team features. Your Grok 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 Grok accounts).

With Composio, you connect Grok 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.
