Institutional memory for the agentic era. Open-source GraphRAG knowledge base: documents in, Neo4j knowledge graph out. Humans get chat + deep research with cited answers, agents get a 100+ endpoint REST API, plug-in apps run right inside the instance. Self-host with one command: npx @mocaos/cortex
Warning. Serious findings were identified. Review the full report before connecting. 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.

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
13/13 tools missing one or more hints — search_knowledge (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ask_question (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_context (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +10 more. 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.
Tool test coverage
8/13 tools referenced in tests (62%)
Write tests that reference each tool by name so every tool has at least one test.
No access to sensitive paths
Reads sensitive paths: /app/.env
Remove reads of sensitive system paths. If you genuinely need them, document why in the README.
