Jmespath Mcp

mukundakatta/mcp-stack

Exposes a single `json_query` tool that runs JMESPath expressions against JSON documents. Ships as pure JavaScript with no native binaries, so it installs cleanly via npx in Claude Desktop, Cursor, Cline, or any MCP client. Reach for it when you need deep JSON traversal with filters, projections, and pipes instead of letting the LLM hallucinate nested property access or array slicing. Part of a fourteen-server collection that also handles CSV parsing, regex testing, and shell quoting. The author built these to give agents reliable transforms for operations they constantly get wrong when synthesizing code on the fly.
