Built for AI Agents 🤖

LangBot is agent-friendly by design — your coding agents (Claude Code, Codex, Copilot, Cursor, …) can operate, extend, and deploy LangBot with first-class support:

• MCP Server — LangBot exposes a built-in Model Context Protocol endpoint at /mcp, mirroring the HTTP API so an agent can manage bots, pipelines, plugins, and models programmatically. Authenticate with the same API key (set a global key in config.yaml or use a per-user key) — no login flow required. Configure it in the Web panel's API & MCP tab.
• In-repo Skills — The skills/ directory is the single source of truth for working with LangBot: plugin development, core development, end-to-end testing, deployment, and operating the LangBot / LangBot Space MCP servers. Point your agent at this directory and it knows how to build.
• AGENTS.md — Every repo ships an AGENTS.md (symlinked to CLAUDE.md) describing architecture, conventions, and the rule that API changes must keep the MCP server and skills in sync.
• llms.txt — Machine-readable project context for LLMs is published on the website.

Cloud / Marketplace: LangBot Space also exposes an MCP server so agents can search and inspect the plugin / MCP / skill marketplace, authenticated with a Personal Access Token.
