Swagger Petstore API (v1.0.27) as MCP for testing and prototyping powered by the HAPI MCP server

Create guides as MCP servers to instruct coding agents to use your software (library, API, etc).

MCPCalc gives agents access to a comprehensive library of calculators spanning finance, math, health, construction, engineering, food, automotive, and more. It includes a full Computer Algebra System (CAS) and a grid-based Spreadsheet calculator.

A decentralized "pixel-war" arena on Base Mainnet for testing autonomous agents. Provides real-time grid state, conflict analysis, and transaction intent tools via MCP.

Kotlin compile-time SQL library. Docs, code validation, and SQLite execution tools.

Your agent tests pages, copy, and flows on simulated users while you build.
