Jan 專屬的 Busabase

把 Jan 連接到 Busabase

Menlo Research's open-source, local-first desktop chat app that runs open models offline (and cloud models via your keys) and acts as an MCP host; a separate terminal 'Jan Agent' shares its MCP config.

Busabase

MCP 連接器

設定步驟

代管聊天沒有 shell、也沒有檔案系統，連接器是唯一的入口。

加入伺服器

把你的聊天用戶端指向 Busabase 的 MCP 端點。

選擇夠用的最小權限

changeRequest 只讓 Agent 提出變更提案，永遠無法自行合併。

驗證

請 Agent 在開始任何工作之前，先呼叫 auth_verify。

逐步說明

這個主機沒有 shell，連接器是唯一的入口。

一覽表

廠商: Menlo Research
連接方式: MCP + OAuth · MCP + API 金鑰
傳輸方式: Streamable HTTP
驗證方式: OAuth（動態註冊）
設定檔: mcp_config.json in the Jan data folder (Linux ~/.local/share/Jan/data, macOS ~/Library/Application Support/Jan/data, Windows %APPDATA%/Jan/data); OAuth tokens in mcp_oauth.json beside it

執行這段指令

Download from https://jan.ai (macOS .dmg, Windows .exe, Linux: flatpak install flathub ai.jan.Jan)

In Jan Desktop open Settings -> MCP Servers and click + Add MCP Server.
Set Transport to HTTP (Streamable HTTP) and URL to https://busabase.com/api/mcp. Name it busabase.
Toggle the server on. Its Auth line should offer Sign in: Jan discovers the OAuth metadata, registers itself dynamically, and runs authorization-code + PKCE in your browser (5-minute wait).
Pick a model with the tools capability, start a chat, and ask it to call auth_verify. Approve the tool call in the card.

API-key alternative: add an Authorization: Bearer <key> header on the server (key from Busabase Settings -> API Keys). A manual header wins and OAuth is never attempted.

已知的注意事項

The model must support tool calling (local models often need tool calling enabled in Model Capabilities). Each tool call needs inline approval unless 'Allow All MCP Tool Permissions' is on. The default tool-call timeout is 30 s. The older reference page (/desktop/mcp) only shows a stdio example; remote HTTP/SSE and OAuth are on the MCP Servers integration page. The docs do not say which OAuth scopes Jan requests; Busabase grants `mcp` for generic scopes. Jan Agent (a separate terminal agent, preview, install `curl -fsSL https://delta.jan.ai/jan-cli/install-jan-agent.sh | bash`) reads the same mcp_config.json and has documented SKILL.md skills in ~/.jan/skills/.
