GenPark JSON Schema Contract Validator
LocalAbout GenPark JSON Schema Contract Validator
GenPark JSON Schema Contract Validator is a Python tool for validating LLM structured outputs against tool contracts. It runs as an MCP server or can be imported as a library, with no third-party runtime dependencies.
Key features
- 01Validates JSON Schema subsets
- 02Checks LLM outputs against tool contracts
- 03Runs on the Python standard library
Use cases
- 01Checking structured output before a tool call
- 02Validating contract-shaped LLM responses
MCP support
Exposes JSON Schema contract validation to MCP clients as an MCP server.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
