# MCP Servers

An MCP server gives your agents extra tools — things like searching a database, calling an API, or reading a service you use. Add them in **Settings → MCP**.

## Add a server

1. Open **Settings → MCP**.
2. Add a server and choose its type:
   - **local** — OpenChamber runs a command on your machine. You give it the command to run and, if needed, environment variables.
   - **remote** — OpenChamber connects to a URL someone else hosts. You give it the URL and any headers it needs (for example an auth token).
3. Save. The server is on by default; you can turn it off without deleting it.

## Where it applies

Pick the scope when you add a server:

- **personal** — available in every project
- **project** — available only in the current project, and saved alongside the project's other settings

Server names use lowercase letters, numbers, hyphens, and underscores.
