Implementation Reference
- src/handlers/branch-operations.js:87-156 (handler)The core handler function that executes the git checkout branch logic using simpleGit. Handles both creating new branches and switching to existing ones.
export async function handleGitCheckoutBranch({ repo_path, branch_name, start_point = null, create = false, }) { try { const git = simpleGit(repo_path); if (create) { // Create and checkout a new branch if (start_point) { await git.checkoutBranch(branch_name, start_point); } else { await git.checkoutLocalBranch(branch_name); } return { content: [ { type: "text", text: JSON.stringify( { success: true, message: `Created and checked out new branch: ${branch_name}`, branch: branch_name, }, null, 2 ), }, ], }; } else { // Just checkout an existing branch await git.checkout(branch_name); return { content: [ { type: "text", text: JSON.stringify( { success: true, message: `Checked out branch: ${branch_name}`, branch: branch_name, }, null, 2 ), }, ], }; } } catch (error) { return { content: [ { type: "text", text: JSON.stringify( { error: `Failed to checkout branch: ${error.message}` }, null, 2 ), }, ], isError: true, }; } } - src/server.js:161-186 (schema)The input schema definition for the git_checkout_branch tool, including parameters, descriptions, and validation rules.
