Feature Request: Please add STDIO transport support alongside existing SSE #242

Description

@githb-ac

Feature Request

GitMCP currently supports SSE transport only.

Please add STDIO transport as an alternative connection method.

Why

Many agent frameworks and CLI-based MCP orchestrators (e.g. mcp2cli)
operate primarily over STDIO. Having to handle SSE separately from
STDIO-based MCP servers adds unnecessary complexity for teams running
fully local or self-hosted agent pipelines.

Proposed Solution

Support STDIO as an optional transport alongside the existing SSE,
following the same pattern as other dual-transport MCP servers.
This would allow users to connect via:

npx gitmcp --stdio {owner}/{repo}

or via a local wrapper that proxies STDIO to the existing SSE endpoint.

Impact

Would make GitMCP fully compatible with STDIO-first agent pipelines
without requiring any changes to existing SSE users.
