GraphRAG Llama Index MCP Server
Enables AI agents to query a local knowledge graph built from document collections using hybrid search (BM25 + vector fusion) and entity-relationship extraction. Supports privacy-first, offline operation with tools for semantic search, entity graph exploration, and corpus statistics.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
searchSearch the GraphRAG knowledge base with THREE distinct modes: **CRITICAL: For ticker symbols (ASTS, RKLB, NBIS) or acronyms, ALWAYS use 'keyword_lookup' FIRST.** Semantic search (entity_connections/thematic_overview) can MISS exact ticker matches. Workflow: 1. Ticker/Acronym Query → Use 'keyword_l…
explore_entity_graphTraverse the knowledge graph starting from a specific entity. Returns the entity, its direct connections (other entities), and the relationships between them. Use this to build reasoning chains or verify facts about a known entity.
get_corpus_statsGet statistics about the indexed knowledge base. Returns counts of documents, chunks, entities, and relationships. Use for corpus health checks or to understand the scale of available data.

TRANSPORTGRAPHRAG_DATABASEPORTTool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
3/3 tools missing one or more hints — search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); explore_entity_graph (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_corpus_stats (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 1 high severity in production deps — @modelcontextprotocol/sdk@1.0.1 (high), express@4.18.2 (low)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
