You want your AI agent to call an API. Today you have to:

1. Find or build an MCP server for that specific API
2. Write tool definitions, parameter schemas, auth handling
3. Test it, debug it, deploy it
4. Repeat for every new API

toolcast does all of this in one command.

# Try it right now with the demo Petstore API (no auth needed)
npx toolcast serve https://petstore3.swagger.io/api/v3/openapi.json

That's it. Your AI agent now has 19 tools for managing pets, orders, and users.

# Add Stripe to your Claude Code config
npx toolcast add stripe

# Or point at any OpenAPI spec
npx toolcast serve https://api.example.com/openapi.json --bearer-token $MY_TOKEN

# See what tools would be generated
npx toolcast inspect
