Composio
Sign in to Composio once per host and give new agents your connected apps
Composio gives Paseo agents the apps you connected in Composio, such as Gmail, Slack, Notion, GitHub, and Linear. Sign in once per host. Every Paseo app connected to that host sees the same connection, and new agents on the host get Composio's MCP tools.
Setup
Open Composio in the sidebar and select Sign in. Your browser opens Composio, where you approve the host. Approval works from any device signed in to Composio, so you can also copy the sign-in link and open it elsewhere.
If you can't use a browser, paste a key instead. A consumer key (ck_) from Composio under Settings, Sessions & API Key gives agents Composio, but the page lists your apps only after browser sign-in. A user API key (uak_) works like browser sign-in.
With the plugin on several hosts, pick the host in the screen header. Each host has its own connection.
What you see
The page shows the signed-in account and every app you connected in Composio, with its accounts, whether a connection expired, and the number of tools. Select Tools on an app to search its tools.
Add to new agents controls whether new agents on the host get the Composio MCP server. Agents can search and run tools across your apps and ask you to connect another app when a task needs it. Existing agents are not changed.
What it stores and sends
Browser sign-in creates a Composio user API key for the host. The plugin stores it in a private file in the daemon's Paseo home, under plugin-data/composio. Sign out deletes the file and revokes a key created by browser sign-in. A pasted key is deleted but not revoked.
Each new agent gets its own Composio session in your personal ("For You") project. The agent's MCP configuration carries the key, as Composio requires, so anyone who can read that host's agent configuration can use your Composio apps. Do not sign in on a host other people use.
The plugin talks only to Composio: backend.composio.dev for sign-in, apps, tools, and sessions, and connect.composio.dev for consumer keys.
Limits
Pi agents are skipped because Pi accepts MCP servers only with its MCP extension. Codex agents get the server as paseo_composio, so an existing Codex login to Composio's own server is not reused. Requires Paseo 0.11.0 or later.
