cogstack-mcp-wrapper
Enables querying and analyzing medical cohorts from CogStack via the Model Context Protocol, supporting SNOMED-CT search, cohort creation, and demographic analysis.
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.
cogstack_search_snomedSearch for SNOMED-CT concepts by keyword
cogstack_create_cohortCreate a patient cohort based on SNOMED terms and demographic filters
cogstack_analyze_cohortGet detailed statistics for a cohort
cogstack_get_statsGet statistics about the loaded CogStack data
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default

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
4/4 tools missing one or more hints — cogstack_search_snomed (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cogstack_create_cohort (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cogstack_analyze_cohort (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +1 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.
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 14 high severity in production deps — @modelcontextprotocol/sdk@0.5.0 (high), axios@1.6.2 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dependency freshness
1/3 production deps stale: node-fetch@2023-11-30 (2.7y)
