MCP Protocol Guidelines

Supported JSON-RPC methods

Method	Handler
`initialize`	Returns server info and capabilities
`tools/list`	Returns `PrToolService.GetToolDefinitions()`
`tools/call`	Routes to `PrToolService.ExecuteAsync`

stdio framing

StdioMessageIO reads Content-Length headers then the JSON body.
The parser tolerates both CRLF (\r\n) and LF (\n) header separators.
Do not change to strict CRLF-only — this breaks the MCP handshake on some hosts.

Startup errors

Fatal startup errors must be written to stderr only, never stdout.
stdout is reserved for MCP JSON-RPC messages.
See Program.cs catch block: Console.Error.WriteLineAsync.

Server identity

The server registers as azure-devops-pr-review version 0.1.0 (set in Program.cs).
