What is the JSON Path Query Engine MCP Server?
Surgically extract fields from complex API responses using JSONPath Plus (8M+ weekly downloads). Saves tokens and prevents hallucination.
The Superpowers
- Surgical Extraction: Full JSONPath syntax (
$.orders[0].total_price,$..email). - Token Efficient: Extract only the 3 fields you need from a 5,000-token payload.
Built-in capabilities (1)
Pass the raw JSON string and a JSONPath expression like "$.orders[0].total_price" or "$.users[*].email". Returns all matching values. Queries and extracts specific values from massive JSON payloads using JSONPath expressions. Eliminates the need to send entire API responses to the LLM context window

Frequently asked questions
What JSONPath syntax is supported?
Full JSONPath Plus: root ($), deep scan (..), array indexing, filters, and recursive descent.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query JSON Path Query Engine tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
