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.
