const composio = new Composio();
const { mcp } = await composio.create("your-user-id", {
toolkits: ["attio"],
mcp: true,
});Create a session scoped to Attio 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: "Create a new company record for Acme Corp with industry and location details.",
stopWhen: stepCountIs(10),
});
console.log(text);
await client.close();Pass the session's MCP URL and headers to your agent and run a Attio request

let response = await client.responses.create({
model: "gpt-5.6-sol",
tools,
input: [{ role: "user", content: "Create a new company record for Acme Corp with industry and location details." }],
});
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,

FAQ
Frequently asked questions
No. Composio provides a managed OAuth app for Attio, so you sign in with your normal Attio account and approve access. If you later want the consent screen to show your own company name, you can add your own Attio OAuth app in the Composio dashboard, and every connection after that uses it.
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 Attio 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.
When you connect a Attio account through Composio, every action runs under that account, so anything the agent creates, sends, or changes shows up in Attio 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.
Exactly the ones Attio lists on its consent screen when you connect. Review that screen before approving. If you connect a work account, your Attio administrator may need to approve the app first, and you can revoke the access inside Attio whenever you want.
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 Attio 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.
Composio refreshes Attio tokens automatically, so day to day you do nothing. If you revoke access inside Attio, or Attio invalidates the session, the connection shows as expired in Composio and the agent stops acting on that account until you reconnect it, which is a single sign-in.
Composio's free plan includes 100,000 tool calls per month with no credit card, and up to 20,000 of those can run through Composio-managed apps like Attio. Personal Attio use rarely gets near that. Paid plans add higher limits and team features, and Attio's own pricing is unaffected.
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 Attio accounts).
With Composio, you connect Attio 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.
