The MCP server agents connect to, at /beamlet/mcp.

It offers three tools:

• Beamlet.MCP.Define - the define tool, which compiles modules into your beamlet.
• Beamlet.MCP.Eval - the eval tool, which runs Elixir code on your beamlet.
• Beamlet.MCP.Patch - the patch tool, which edits a module agents defined.

Every request needs a token, and the token's policy decides which of the tools the client sees.

Configuration

config :beamlet, mcp: [request_timeout: 90_000]

• :request_timeout - How long the server waits for a tool to answer before replying "Server unavailable", in milliseconds. Defaults to 65 seconds. It must be longer than the eval and define timeouts, so a slow tool reports its own error first.
