git-insight-mcp

Semantic git queries via MCP. Beyond git log — answer who/what/when/why about any line, file, or branch.

Pairs with terminal-history-mcp and localhost-mcp. Together: what you ran, what's running, what you changed.

Why

Devs ask these constantly; git answers poorly:

  • "Who last touched this function?" — git blame only gives lines, not authors-by-region
  • "What PR introduced this line?" — manual: blame → commit SHA → search GH
  • "Which files always change together?" — no built-in
  • "Show unmerged branches older than 30 days" — bash one-liner gymnastics
  • "What did I work on last week?" — manual log scrub

LLM agents need this context to make safe edits. Currently they git log -n 5 and miss everything.

Install

npm install -g git-insight-mcp

Wire into Claude Code:

claude mcp add --scope user git-insight -- git-insight-mcp

Or any MCP-compatible client. Runs as a stdio MCP server.

For PR / issue lookups, set a GitHub token:

export GH_TOKEN=ghp_...

Without a token, the local-git tools still work. PR linkage is skipped.

Tools

ToolPurpose
who_touchedGroup blame by author. Lines, commits, last-touched, primary owner. Optional line-range narrowing.
introducing_prFind the PR that introduced a line (or commit). Parses merge messages first; falls back to GitHub API.
co_changeFiles most often changed together with the input file.
branch_hygieneList branches with ahead/behind, last commit, merged status, stale flag.
recent_workStandup helper: author's commits + files + ins/del in a window.
commit_contextFull commit context: subject, body, files, PR, related issues.

Sample output (who_touched)

{
  "file": "src/auth.ts",
  "total_lines": 124,
  "authors": [
    { "name": "alice", "email": "alice@x.com", "lines": 87, "commits": 12, "last_commit_date": "2026-04-12T10:33:01.000Z" },
    { "name": "bob", "email": "bob@x.com", "lines": 37, "commits": 4, "last_commit_date": "2026-01-03T18:14:55.000Z" }
  ],
  "primary_owner": "alice"
}

CLI usage (sanity checks)

Limits (v0.1)

  • GitHub only (no GitLab/Bitbucket yet).
  • co_change is O(window × files-per-commit) — defaults capped at 1000 commits.
  • Function-level blame is by line range, not AST. Renames not yet tracked.
  • GH API rate limit applies (5000/h authed). PR results uncached this version.
