Engram Context Continuum
Universal AI session memory substrate providing persistent context across sessions, with MCP tools for recall, search, recent events, and knowledge graph queries.
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.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

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
150/150 tools missing one or more hints — npm install mongoose @types/mongoose (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); npm uninstall mongoose && npm install prisma @prisma/client (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); npm run build -- OK (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +147 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.
Shell command execution
18 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
No arbitrary install scripts
Has postinstall/preinstall script — runs arbitrary code on npm install
Remove postinstall/preinstall hooks unless they’re essential.
Production dependencies are patched
0 critical, 1 high severity in production deps — js-yaml@4.1.0 (high), js-yaml@4.1.0 (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.
