SETUP GUIDE

Connect Bread & Butter 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: ["bread_butter"],
  mcp: true,
});
Create a session scoped to Bread & Butter 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: "Find high-intent Bread & Butter website visitors from the past 24 hours and summarize their profiles",
  stopWhen: stepCountIs(10),
});

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

FAQ

Frequently asked questions

Yes, Bread & Butter requires you to configure your own API key. 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 Bread & Butter 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 Bread & Butter account settings, then paste it once on Composio's connection page. Composio stores it encrypted and uses it only for the Bread & Butter actions your agent runs. Nobody else in your workspace can read it, and you can revoke it inside Bread & Butter at any time.

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

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

With Composio, you connect Bread & Butter 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.
