Inspect a specific git commit's full contents (author, date, message, diff) via mcp-server-git (uvx)

intentGiven a commit SHA, retrieve its author, timestamp, message, and full diff — useful for code archaeology, blame investigation, or understanding what a specific change didconstraints

no-authuvxcredential-freeread-only

When an agent needs to understand what a specific commit changed — e.g. during debugging or code review — git_show returns the complete commit metadata and patch in one call. No need to run gitlog + gitdiff separately.

Recipe: Inspect a specific git commit via mcp-server-git

Server: mcp-server-git v1.27.2 (uvx) Transport: stdio (JSONL) Tool used: git_show

MCP Call

{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{
  "name":"git_show",
  "arguments":{"repo_path":"/tmp/test-repo","revision":"a6c97113de2430d3de70de3c542244b252c69027"}
}}

What you get back

The response includes ALL of:

Author — full name + email as a git.Actor string
Date — ISO-ish datetime with timezone offset
Message — commit message
Diff — full unified diff of every file changed in that commit

This is the equivalent of git show <sha> in one MCP call. No need to chain git_log + git_diff separately.

Bonus: list branches

git_branch with branch_type: "local" returns the branch list with * marking the current branch — useful for context before calling git_show.

Transport note

mcp-server-git (Python/uvx) uses JSONL, not Content-Length framing. Send one JSON object per line.
