+# Mcp4rdf - RDF Validation Server with AI
+
+**Space Link:** [https://huggingface.co/spaces/jimfhahn/mcp4rdf](https://huggingface.co/spaces/jimfhahn/mcp4rdf)
+
+This is a Gradio app that serves as an RDF validation tool and an MCP (Model Context Protocol) server. It allows users to validate RDF/XML content against SHACL schemas, and provides AI-powered suggestions and corrections for validation errors using a Hugging Face Inference Endpoint.
+
+**Track:** MCP Server / Tool
+**Tag:** `mcp-server-track`
+
+## MCP Server in Action
+
+The MCP server can be tested by connecting an MCP client to the Gradio app's API endpoint.
+The application is live and can be accessed at the Space Link above.
+
+## Features:
+- Real-time RDF/XML validation against SHACL schemas (Monograph and custom templates).
+- AI-powered error suggestions and corrections via a Hugging Face Inference Endpoint.
+- Built-in examples for valid, invalid, and BibFrame RDF.
+- Auto-validation as you type.
+- Easy-to-use Gradio interface.
+- Exposes MCP server functionality for clients like Claude Desktop.
+
+## MCP Server Tools Exposed:
+- `validate_rdf_tool`: Validate RDF/XML against SHACL shapes.
+- `get_ai_suggestions`: Get AI-powered fix suggestions.
+- `get_ai_correction`: Generate corrected RDF/XML.
+- `get_rdf_examples`: Retrieve example RDF snippets.
+
+## Setup and Deployment on Hugging Face Spaces:
+
+1.  **Hugging Face Space:** This application is deployed at [https://huggingface.co/spaces/jimfhahn/mcp4rdf](https://huggingface.co/spaces/jimfhahn/mcp4rdf).
+2.  **Inference Endpoint:** The application is configured to use a specific Hugging Face Inference Endpoint for AI features.
+3.  **API Key:** To enable AI features, the `HF_API_KEY` (your Hugging Face API token with access to the Inference Endpoint) must be set as a Secret in the Space settings.
+    *   Go to your Space → Settings → Repository secrets.
+    *   Add: `HF_API_KEY` = `your_huggingface_api_key_here`.
+4.  **Requirements:** The Space automatically installs dependencies from `requirements.txt`.
+
+## MCP Connection:
+1.  When deployed on Hugging Face Spaces, the MCP server is available at:
+    `https://jimfhahn-mcp4rdf.hf.space/gradio_api/mcp/sse` (Note: The Space ID `jimfhahn-mcp4rdf` might vary slightly based on HF naming conventions, please verify the exact URL from your Space).
+2.  Use this URL in your MCP client's configuration (e.g., Claude Desktop).
