Build plugins

Agents and MCP

Let Claude Code and other MCP clients use your plugins' tools, and let them write plugins for you.

Stackbar speaks the Model Context Protocol in two ways.

Your plugins as tools

A plugin can offer tools (PR Cockpit lists your pull requests, Todo adds a task). Settings › Agents turns the gateway on and shows the command to connect a client, ready to copy. For Claude Code:

claude mcp add stackbar -- stackbarctl agent

The agent sees every running plugin’s tools, and each call goes through the app with the same sandbox and approvals as a click.

An agent that writes plugins

stackbarctl mcp is an authoring server: an agent can scaffold a plugin, build it, render each surface as text, press its buttons and read the logs, without the app open. The plugin reference is the same text the server serves, and is also at /llms.txt.
