+# OpenIsle MCP Server
+
+This package provides a [Model Context Protocol](https://modelcontextprotocol.io) (MCP) server
+that exposes OpenIsle's search capabilities as MCP tools. The initial release focuses on the
+global search endpoint so the agent ecosystem can retrieve relevant posts, users, tags, and
+other resources.
+
+## Configuration
+
+The server is configured through environment variables (all prefixed with `OPENISLE_MCP_`):
+
+| Variable | Default | Description |
+| --- | --- | --- |
+| `BACKEND_BASE_URL` | `http://springboot:8080` | Base URL of the OpenIsle backend. |
+| `PORT` | `8085` | TCP port when running with the `streamable-http` transport. |
+| `HOST` | `0.0.0.0` | Interface to bind when serving HTTP. |
+| `TRANSPORT` | `streamable-http` | Transport to use (`stdio`, `sse`, or `streamable-http`). |
+| `REQUEST_TIMEOUT` | `10.0` | Timeout (seconds) for backend HTTP requests. |
+
+## Running locally
+
+```bash
+pip install .
+OPENISLE_MCP_BACKEND_BASE_URL="http://localhost:8080" openisle-mcp
+```
+
+By default the server listens on port `8085` and serves MCP over Streamable HTTP.
+
+## Available tools
+
+| Tool | Description |
+| --- | --- |
+| `search` | Perform a global search against the OpenIsle backend. |
+| `reply_to_comment` | Reply to an existing comment using a JWT token. |
+| `recent_posts` | Retrieve posts created within the last *N* minutes. |
+
+The tools return structured data mirroring the backend DTOs, including highlighted snippets for
+search results, the full comment payload for replies, and detailed metadata for recent posts.
