## MCP

Oh My Posh exposes an MCP (Model Context Protocol) endpoint for validating prompt configurations:

- `POST /api/mcp` — JSON-RPC 2.0; supports tools/list, tools/call, initialize
- `GET /api/mcp` — returns server info and available tools
- Tools: `validate_config` (full config), `validate_segment` (individual segment)
- Formats: JSON, YAML, TOML (auto-detected)
- Discovery: `/.well-known/mcp.json`

## Examples

Detect current shell:

```bash
oh-my-posh get shell
```

Validate a config via MCP:

```bash
curl -X POST https://ohmyposh.dev/api/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"tools/call","params":{"name":"validate_config","arguments":{"content":"{\"version\":3}","format":"json"}},"id":1}'
```
