Integrations

hummin meets the rest of your toolchain without plugins-by-GUI: MCP, LSP, web, and a full automation surface.

MCP client

Model Context Protocol servers configured under mcpServers (stdio JSON-RPC). Their tools appear as model-callable mcp_<server>_<tool> entries.

/mcp       # server status + restart

TypeScript LSP

When typescript-language-server is available, the model gets real language tools instead of grep-shaped guessing:

Tool Purpose
lsp_diagnostics Type errors, live
lsp_definition Jump to definition
lsp_references Find all references
lsp_hover Type info 
/lsp       # server status + restart

Web

  • web_search - DuckDuckGo search
  • web_fetch - fetch with an SSRF guard (internal addresses and metadata endpoints are refused)

cc-tg-hub Telegram bridge

With a cc-tg-hub broker running (installed once with bunx cc-tg-hub setup), TG_HUB=1 hummin registers the session with the broker and makes it drivable from your phone:

  • One Telegram forum topic per session; messages arrive as user input (steering the current turn when one is running).
  • A tg_reply tool answers the topic.
  • Tools listed in TG_HUB_ASK_TOOLS (or tgHub.askTools) raise Allow/Deny buttons before they run - Deny blocks the call; Allow never bypasses a terminal dialog, so pair it with --approve for fully unattended use.

Claude Code sessions and hummin sessions can share one broker, one bot, one poller. One broker per machine (Telegram allows one getUpdates poller per bot token). Claude Code sessions need their own flag: claude --dangerously-load-development-channels server:cc-tg-hub.

Extensions

TypeScript extensions in ~/.hummin/agent/extensions/ autoload at startup with hot reload and a transform cache. This is the mechanism behind the local fleet provider - see Connecting to hummin - and it is the same API available to yours.

Prompt templates, skills, packages

  • Skills follow the Agent Skills standard: /skill:<name>.
  • Prompt templates become first-class slash commands.
  • Packages install from npm or git: hummin package install|remove|update|list.

Automation surface

  • SDK for embedding, RPC mode and JSON event mode for scripts.
  • hooks.json for shell-level lifecycle automation (see Safety).
  • Cron for scheduled wake-ups (see Agent Teamwork).
  • /remote-control - loopback browser view of the session with prompt/abort, for when you want to drive from a phone-shaped window on the same machine.
