Description

JSON Query MCP provides a Model Context Protocol server for querying and searching large JSON documents. It supports JSONPath queries and similarity searches for both keys and values, enabling agents to extract small, focused portions from massive JSON files (e.g., >1M characters). The tool is easy to run locally (via npx) and integrates with Cursor by adding it to MCP configuration, making it useful for LLM-driven workflows that need efficient JSON access.
