+
+# MCP server (FrikaMF modding)
+
+The repository ships a **Model Context Protocol (MCP)** server (`mcp-server/`) that exposes:
+
+- **Docs search & read** — Markdown under `docs/` (same source as Docusaurus).
+- **Hook registry** — `fmf_hooks.json` (and the same registry path in the monorepo).
+- **CONTRIBUTING** — conventions and workflow.
+- **Repo layout** — static overview and a **`fmf_modding_context`** prompt for quick context.
+
+Use it when you want an assistant (Cursor, Claude Code, or any MCP client) to **ground answers** in this repo instead of guessing APIs.
+
+## Docker (single container)
+
+The root `Dockerfile` builds **Docusaurus** into static files and runs **one Node process** that:
+
+- Serves the wiki at **`http://<host>:3000/`** (static HTML).
+- Exposes **Streamable HTTP MCP** at **`POST /mcp`** and **`GET /mcp`** (SSE), plus **`GET /health`**.
+
+From the repo root:
+
+```bash
+docker compose up docs-mcp
+```
+
+Default mapping: **`http://localhost:3040`** (host) → container port **3000**.
+
+- Docs: `http://localhost:3040/wiki/`
+- Health: `http://localhost:3040/health`
+- MCP: `http://localhost:3040/mcp` (client must speak MCP Streamable HTTP; session via `mcp-session-id` header).
+
+:::note Security
+
+Binding to `0.0.0.0` exposes the MCP endpoint on your network. Use only on trusted networks or behind a reverse proxy with authentication.
+
+:::
+
+## Local (stdio) for Cursor
+
+From `mcp-server/` with the repo root as data (so `docs/`, `CONTRIBUTING.md`, and `FrikaModFramework/fmf_hooks.json` resolve):
+
+```bash
+cd mcp-server
+node src/index.mjs --stdio --data-root ..
+```
+
+Point your MCP client at this command (stdio transport). Adjust `--data-root` if your layout differs.
