- src/tools/dev-tools.ts:79-98 (handler)Handler function that runs the git log command, parses output with parseGitLog, and returns JSON array of commits.async ({ path: gitPath, maxCount }) => { return wrapToolExecution(async () => { const { stdout } = await execAsync( `git log -${maxCount} --pretty=format:"%H|%an|%ad|%s" --date=iso`, { cwd: gitPath } ); const commits = parseGitLog(stdout); return { content: [{ type: "text" as const, text: JSON.stringify(commits, null, 2) }] }; }, { errorCode: ERROR_CODES.GIT_OPERATION, context: "Failed to get git log" }); }
- src/tools/dev-tools.ts:75-78 (schema)Zod input schema defining optional 'path' (git directory) and 'maxCount' (number of commits).{ path: z.string().optional().default("."), maxCount: z.number().optional().default(DEFAULTS.MAX_COMMITS) },
- src/tools/dev-tools.ts:73-100 (registration)Registers the 'git_log' tool with the MCP server, including schema and handler function.function registerGitLog(server: McpServer): void { server.tool("git_log", { path: z.string().optional().default("."), maxCount: z.number().optional().default(DEFAULTS.MAX_COMMITS) }, async ({ path: gitPath, maxCount }) => { return wrapToolExecution(async () => { const { stdout } = await execAsync( `git log -${maxCount} --pretty=format:"%H|%an|%ad|%s" --date=iso`, { cwd: gitPath } ); const commits = parseGitLog(stdout); return { content: [{ type: "text" as const, text: JSON.stringify(commits, null, 2) }] }; }, { errorCode: ERROR_CODES.GIT_OPERATION, context: "Failed to get git log" }); } ); }
- src/tools/dev-tools.ts:102-113 (helper)Helper function to parse git log output into structured GitCommit objects.function parseGitLog(stdout: string): GitCommit[] { const lines = stdout.trim().split('\n').filter(line => line); return lines.map(line => { const [hash, author, date, message] = line.split('|'); return { hash: hash.substring(0, 8), author, date, message }; }); }
