### What it can do

Tools: not known by name. The server needs sign-in before it lists them, and the vendor's documentation doesn't name them, so this is what it says the server can do ([source](https://alloy.app/guide/integrations/mcp)), read on 2026-11-02. It may be out of date.

- Session metadata, including title, type, timestamps, status, and workspace context.
- Chat messages from a session.
- File lists for sessions.
- Prototype session file content.
- Before-and-after file diffs where available.

### Connect it

Claude Code:

```sh
claude mcp add --transport http alloy https://mcp.alloy.app/mcp
