CometAPI MCP server for AI agents and assistants

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with CometAPI MCP or direct API to generate text, create images, transcribe audio, and compare model outputs through natural language.

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

Create Chat Completion

Create a non-streaming Chat Completions result for message-based conversations and function-calling workflows.

Create Embeddings

Create OpenAI-compatible embedding vectors for one text or a batch of texts.

Create Response

Create a non-streaming OpenAI Responses API result.

Get API Key Usage

Return quota, usage, expiration, and model restrictions for the connected CometAPI API key.

List Models

List all models available to the connected API key, including provider ownership and supported protocol types when returned.

SETUP GUIDE

Connect CometAPI 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: ["cometapi"],
  mcp: true,
});
Create a session scoped to CometAPI 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: "Generate a short product description for a new AI image editing app using CometAPI",
  stopWhen: stepCountIs(10),
});

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

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

Run CometAPI tools with your agent

typescript
let response = await client.responses.create({
  model: "gpt-5.6-sol",
  tools,
  input: [{ role: "user", content: "Generate a short product description for a new AI image editing app using CometAPI" }],
});

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

Why Use Composio?

AI Native CometAPI Integration

  • Supports both CometAPI MCP and direct API based integrations
  • Structured, LLM-friendly schemas for reliable tool execution
  • Rich coverage for sending model requests, checking responses, and working with multi-provider AI workflows

Managed Auth

  • Secure API key handling so agents don't need hard-coded CometAPI credentials
  • Central place to manage, scope, and revoke CometAPI access
  • Per user and per environment credentials for safer AI model operations

Agent Optimized Design

  • Tools are tuned using real error and success rates to improve reliability over time
  • Comprehensive execution logs so you always know which CometAPI action ran, when, and on whose behalf

Enterprise Grade Security

  • Fine-grained RBAC so you control which agents and users can access CometAPI
  • Scoped, least privilege access to CometAPI model and generation workflows
  • Full audit trail of agent actions to support review and compliance
FAQ

Frequently asked questions

Yes, CometAPI requires you to configure your own API key credentials. Once set up, Composio handles secure credential storage and API request handling for you.

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

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

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

With Composio, you connect CometAPI 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.
