Busabase MCP server

Busabase Skills & Plugins

English | 简体中文 | 繁體中文 | 日本語

Agent Skills + plugins for Busabase — the approval-first knowledge base where AI proposes changes, a human reviews them, and only approved changes get merged.

Two skills, five ways to install them — pick whatever your agent supports.

Install

skills (Claude Code, Cursor, Codex, … — evergreen)

npx skills add busabase/skills

Agent Plugins v1 (portable package)

The repository root follows the Agent Plugins Specification v1.0.0: plugin.json is the portable manifest, skills/ contains the Agent Skills, and mcp.json declares the hosted Streamable HTTP MCP server. Install or load this repository root with any client that supports the Agent Plugins format.

Agent Plugins v1 leaves OAuth and credentials to the client. Existing Claude Code and Codex packages keep their dedicated browser-OAuth behavior. See docs/agent-plugins.md for the compatibility mapping and validation.

Claude Code plugin

claude plugin marketplace add https://github.com/busabase/skills.git
claude plugin install busabase@busabase
claude mcp login plugin:busabase:busabase

The Claude Code plugin connects to https://busabase.com/api/mcp with browser OAuth. Claude namespaces its bundled server as plugin:busabase:busabase. Start a new conversation after install and login so the authenticated tool catalog is available. See docs/claude-code-install.md for the complete verification and recovery flow.

Maintainers should also read docs/codex-to-claude-code-port.md for the host-by-host manifest, MCP, OAuth, skill, and validation differences.

Codex plugin

codex plugin marketplace add busabase/skills
codex plugin add busabase@busabase
codex mcp login busabase

The Codex plugin connects to https://busabase.com/api/mcp, opens the standard browser OAuth flow, and exposes a focused 22-tool catalog. No API key setup is required.

Plugin installation and MCP authorization are separate states. After the browser says Authentication complete, verify the saved connection before starting a Busabase task:

codex mcp list

The busabase row should show Auth as OAuth. If it still shows Not logged in, run codex mcp login busabase again and complete the newly opened browser tab while that command is still running. Start a new Codex task after a successful login so the task loads the authenticated tool catalog.

MCP (any MCP-capable agent)

Point your agent at your workspace's Streamable-HTTP endpoint:

• Desktop / local: http://localhost:15419/api/mcp (no auth)
• Cloud: https://busabase.com/api/mcp (send Authorization: Bearer $BUSABASEAPIKEY)

Codex can use the full Cloud MCP surface directly with standard OAuth:

codex mcp add busabase --url https://busabase.com/api/mcp
codex mcp login busabase

The portable root mcp.json declares the hosted endpoint using the Agent Plugins v1 format. The legacy root .mcp.json continues to wire the local endpoint for general MCP clients. The Claude package uses its own hosted OAuth MCP configuration. The Codex plugin has a separate remote MCP configuration.

The root busabase skill remains the full CLI/curl guide for local and general-purpose agent installs. The Claude- and Codex-bundled skills are intentionally MCP-first: they rely on OAuth and the curated tool catalog instead of reading ~/.busabase/.env.

To set up a workspace from scratch first, paste the onboarding prompt from your Busabase dashboard (Agent Skills button) — it walks your agent through connecting, seeding a first Base, and then running one of the install commands above.
