MCP Integrations

🧰 MCP integrations

Available only on the native chat path. Start the proxy with --use-native-chat, or with --native-chat-streaming if you only need it on streaming requests (see Configuration).

On that path /api/chat accepts an integrations array, forwarded verbatim to LM Studio's /api/v1/chat. Non-array values are ignored.

Element types

Each element of the array may be:

• A bare plugin-id string: "huggingface"
• A plugin object: {"type": "plugin", "id": "browser", "allowed_tools": ["browser_navigate"]}
• An ephemeral MCP server: {"type": "ephemeral_mcp", "server_label": "hf", "server_url": "https://hf.co/mcp", "allowed_tools": ["model_search"], "headers": {}}

LM Studio settings

Enable the matching options under Developer in the LM Studio UI:

• Allow calling servers from mcp.json enables plugin entries.
• Allow per-request MCPs enables ephemeral_mcp entries.

Overrides such as stop or seed ride alongside these untouched.
