How to Use the API Design Prover MCP in Windsurf
Stop shipping broken endpoints. Use API Design Prover in Windsurf to catch contract flaws before you write a single line of code.
Works with every AI agent you already use
…and any MCP-compatible client
Connect API Design Prover MCP to Windsurf
Create your Vinkius account to connect API Design Prover to Windsurf and route execution through our secure gateway. The platform manages server hosting, runtime updates, and security layers. Configuration requires no manual server provisioning.
Enforce strict HTTP semantics in Windsurf
Cascade needs to map every endpoint to the right verb before you start coding. The `validate_api_design` tool forces you to declare these mappings explicitly so you don't end up with POST requests doing GET jobs. Windsurf picks up these constraints immediately. It prevents your agent from hallucinating endpoints that violate standard REST conventions.
Define error contracts for your Windsurf project
You need consistent error shapes across your entire backend. This tool requires you to define RFC 7807 compliant structures so your clients never guess what a 400 or 500 error means. Once you run `validate_api_design`, Windsurf knows exactly how your server should respond. It stops the agent from building brittle code that fails when the data isn't perfect.
Standardize pagination within Windsurf
Stop letting your API design grow unbounded. The tool mandates a clear pagination strategy including max page sizes so your database doesn't crash under load. Cascade uses this design as a guardrail. It ensures the code it writes respects these limits from the very first commit.
