Composio

Composio is an integration platform built for AI agents, giving Claude, GPT, Gemini and other models a single set of tools to reach into more than 250 third-party apps — Gmail, Slack, Notion, Salesforce, GitHub, Google Calendar, HubSpot and dozens more. Instead of writing custom API clients and OAuth flows for every service a business relies on, teams expose one Composio MCP server and let the agent discover available actions, request a connection, and call the app directly. The platform handles credential storage, token refresh, and per-user authorization so 'connect an integration' becomes a tool call rather than an engineering project. For teams evaluating an OAuth integration platform for AI agents or looking to connect 250+ apps to AI agents without building bespoke connectors, Composio is one of the fastest paths to a working agent stack.

Hosting Composio through BusinessMCP turns that integration layer into part of a unified, business-wide MCP server rather than one more isolated tool an agent has to juggle. Once connected, Composio's app catalog, OAuth flows, and action schemas are reachable from your company's single /api/mcp endpoint alongside your databases, ad platforms, and revenue data, authenticated with one Bearer mcph_* key. Because the hosted endpoint is model-agnostic, the same Composio connection serves Claude, GPT, Gemini or any other agent your team adopts — no re-plumbing integrations every time you switch models or add a new one. The accompanying business-intelligence dashboard gives visibility into which integrations are being called, by which agents, and how often, so integration sprawl doesn't turn into a black box.

Composio is a strong fit anywhere an agent needs to act across multiple business systems in one workflow: triaging support tickets by reading a CRM record, posting a Slack update, and opening a GitHub issue in the same conversation; syncing marketing data between an ad platform and a spreadsheet app; or automating onboarding tasks that touch email, calendar, and a project-management tool. Managed OAuth is the real unlock here — agents can request user consent, refresh expiring tokens, and re-authenticate on failure without a human manually rotating keys, which matters as soon as you move from a demo integration to something running unattended in production.

Because BusinessMCP's layer sits in front of Composio, the connection is cookieless and built with GDPR-friendly data handling in mind, which matters for teams routing customer or employee data through third-party app connections. Composio pairs naturally with other servers in the BusinessMCP catalog: use it alongside a database MCP server to persist what an agent retrieves from a connected app, a memory server to retain context across multi-step integration workflows, or a code/GitHub server when the workflow includes shipping a fix as well as notifying a channel. Rather than standing up and securing 250 separate OAuth integrations, host Composio once, expose it through your unified MCP endpoint, and let any agent in your growth suite pick up new app connections as they're added.
