Composio

A hosting layer for MCP servers — it runs the server and handles the auth so you only paste a URL.

Pick this when

You want a third-party integration without self-hosting anything or managing OAuth yourself.

What makes it different

Hosted servers mean no install and no local process to keep alive

Handles the underlying service authorization as part of the connect flow

Hosts MCP servers for common SaaS tools (the Google Sheets server used in BC5)

Manages the OAuth handshake to the underlying account

Common wrong expectations

Doesn't remove the trust question — a hosted third party sits between you and your data

No third-party MCP need at present.

For your projects

Note the data-path question for anything involving Paul's own accounts: a hosted server means the traffic isn't local.
