Summary

• stop passing raise_exceptions=True when starting the Python git server
• align git server behavior with sibling Python servers so JSON-RPC validation errors are returned to the client instead of crashing the process
• add a regression test covering the serve() startup path

Testing

• uv run pytest tests/test_server.py -q
• uv run ruff check tests/test_server.py src/mcp_server_git/server.py
• uv run pyright

Closes #4213

Thank you for this pull request, and apologies for the long wait for a response.

Since it was opened, the reference servers have been rebuilt for the 2026-07-28 MCP specification (#4857) and released as v2 (2.0.0 on npm for the TypeScript servers, 2026.10.19 on PyPI for the Python servers). The code this PR changes has been replaced, and the behavior it addresses has either been fixed in v2 or no longer exists in the same form.

This is not a judgment on the change or on you; it's a consequence of the code it targets having been replaced. If the problem still happens on v2, please open a fresh issue with the version you're running and steps to reproduce. Note that this repository now accepts contributions as issues rather than pull requests from anyone but its maintainers; see CONTRIBUTING.md.

This is part of the backlog triage in #4875.
