git_remote

Instructions

Implementation Reference

• src/tools/git.ts:349-382 (handler)

  The main handler function for the 'git_remote' tool. Executes git remote commands (list, add, remove, show) using the shared executeGitCommand helper, with input validation via gitRemoteSchema.

  export async function gitRemote(args: z.infer<typeof gitRemoteSchema>): Promise<ToolResponse> {
    switch (args.action) {
      case 'list':
        return executeGitCommand('git remote -v', args.cwd);
      case 'add':
        if (!args.name || !args.url) {
          return {
            content: [{ type: "text", text: JSON.stringify({ success: false, error: 'Name and URL required for add action' }, null, 2) }],
            isError: true
          };
        }
        return executeGitCommand(`git remote add ${args.name} ${args.url}`, args.cwd);
      case 'remove':
        if (!args.name) {
          return {
            content: [{ type: "text", text: JSON.stringify({ success: false, error: 'Name required for remove action' }, null, 2) }],
            isError: true
          };
        }
        return executeGitCommand(`git remote remove ${args.name}`, args.cwd);
      case 'show':
        if (!args.name) {
          return {
            content: [{ type: "text", text: JSON.stringify({ success: false, error: 'Name required for show action' }, null, 2) }],
            isError: true
          };
        }
        return executeGitCommand(`git remote show ${args.name}`, args.cwd);
      default:
        return {
          content: [{ type: "text", text: JSON.stringify({ success: false, error: 'Invalid remote action' }, null, 2) }],
          isError: true
        };
    }

• src/tools/git.ts:162-167 (schema)

  Zod schema for validating inputs to the git_remote tool, used in the dispatch handler in index.ts.

  export const gitRemoteSchema = z.object({
    cwd: z.string().optional().describe('Repository directory'),
    action: z.enum(['list', 'add', 'remove', 'show']).optional().default('list').describe('Remote action'),
    name: z.string().optional().describe('Remote name (required for add/remove/show)'),
    url: z.string().optional().describe('Remote URL (required for add)')
  });

• src/index.ts:413-416 (registration)

  Dispatch registration in the main MCP server handler. Matches tool name, validates args with schema, and calls the gitRemote handler.

  if (name === 'git_remote') {
    const validated = gitRemoteSchema.parse(args);
    return await gitRemote(validated);
  }

• src/tools/git.ts:683-694 (schema)

  MCP tool definition in gitTools array, including inputSchema for tool listing. Mirrors the Zod schema.

  {
    name: 'git_remote',
    description: 'Manage remote repositories',
    inputSchema: {
      type: 'object',
      properties: {
        cwd: { type: 'string', description: 'Repository directory' },
        action: { type: 'string', enum: ['list', 'add', 'remove', 'show'], default: 'list', description: 'Remote action' },
        name: { type: 'string', description: 'Remote name (required for add/remove/show)' },
        url: { type: 'string', description: 'Remote URL (required for add)' }
      }
    }

• src/tools/git.ts:21-60 (helper)

  Shared helper function used by all git tools, including gitRemote, to execute git commands and format responses.

  async function executeGitCommand(command: string, cwd?: string): Promise<ToolResponse> {
    try {
      const { stdout, stderr } = await execAsync(command, {
        cwd: cwd || process.cwd(),
        shell: '/bin/bash',
        maxBuffer: 10 * 1024 * 1024 // 10MB buffer
      });
  
      return {
        content: [
          {
            type: "text" as const,
            text: JSON.stringify({
              success: true,
              command: command,
              stdout: stdout.trim(),
              stderr: stderr.trim(),
              cwd: cwd || process.cwd()
            }, null, 2)
          }
        ]
      };
    } catch (error: any) {
      return {
        content: [
          {
            type: "text" as const,
            text: JSON.stringify({
              success: false,
              command: command,
              stdout: error.stdout?.trim() || '',
              stderr: error.stderr?.trim() || error.message,
              exitCode: error.code || 1,
              cwd: cwd || process.cwd()
            }, null, 2)
          }
        ],
        isError: true
      };
    }
