Build & extend

This section is for developers. Whether you are calling the platform from your own services, automating with Terraform, giving agents new tools via MCP, building a custom agent CLI, or shipping an app that participates in conversations — this is where the implementation details live.

Pages

Integration surfaces

  • Gateway API — the ConnectRPC entry point for everything external clients do.
  • Terraform provider — manage platform resources as code.
  • agyn CLI — interactive and scripting access from your shell.

Giving agents new capabilities

  • MCP servers — write your own Model Context Protocol server to expose tools.
  • files-mcp — the platform's built-in file-access MCP, as a reference and as an integration target.

Building agent runtimes

  • Agent CLIs — choose between Codex, Claude Code, and native agn — or write your own.
  • agynd — the wrapper daemon every agent CLI runs under.

Building apps

  • Apps — independently deployed services that participate in conversations as identities.
