<Info>
The `openmcp.json` endpoint provides standardized metadata about your MCP server, allowing clients and tools to discover its capabilities. mcp-use automatically generates this endpoint based on your `ServerConfig`.

## What is OpenMCP?

OpenMCP is a standardized metadata format for MCP servers. It provides a JSON endpoint that describes what tools, resources, and capabilities your server offers.

## Why Use OpenMCP?

OpenMCP enables automatic discovery of MCP server capabilities:
- **Client Integration**: MCP clients can automatically discover available tools and resources
- **Schema Information**: Provides input/output schemas for tools
- **Standardized Format**: Consistent format across all MCP servers
- **Easy Discovery**: Clients can query `/openmcp.json` to understand server capabilities

## Basic Configuration

```python
from mcp_use.server import MCPServer

server = MCPServer(
    name="my-server",
    version="1.0.0",
    description="My MCP server"
)

@server.tool()
def greet(name: str) -> str:
    """Greet someone with a personalized message."""
    return f"Hello, {name}!"

# The openmcp.json endpoint is automatically available at /openmcp.json
```

## Example Output

```json
{
  "openmcp": "1.0",
  "info": {
    "title": "Example Server",
    "version": "0.1.0",
    "description": "This is an example server with a simple echo tool."
  },

    "prompts": {"listChanged": false},
    "resources": {"subscribe": false, "listChanged": false},

      }
    }
  ],
  "resources": [],
