What is Shipcheck MCP?
Shipcheck MCP is an MCP server that lets local MCP clients run Shipcheck on authorized JavaScript and TypeScript repositories. It performs defensive static analysis to detect launch risks such as exposed private-looking environment variables, unsigned Stripe webhooks, missing Supabase/Firebase rule evidence, debug routes, missing usage-cost guardrails, missing CI, loose dependencies, thin release docs, missing MCP smoke-test proof, undocumented STDIO execution boundaries, and undocumented remote MCP auth boundaries.
How to use Shipcheck MCP?
Run directly with npx --yes shipcheck-mcp. Add the server to an MCP client's stdio configuration using command: "npx" and args: ["--yes", "--package", "shipcheck-mcp", "shipcheck-mcp"]. Once configured, invoke the scan_repository tool with parameters such as root, format, failOn, and strict.
