js-doc-store (MauricioPerera/js-doc-store) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. The publisher has proved control of what we score (Verified Publisher). It is connected through the M8ven GitHub App, so the listing is re-checked on every push.
Zero-dependency vanilla JS document database in one file. MongoDB-style queries, indices, joins, aggregation, full-text search, graph traversal, field encryption, and JWT auth.
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.

M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
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
20/20 tools missing one or more hints — schema_define (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); schema_exists (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); schema_usage_guide (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +17 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.
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.
Shell command execution
26 calls in production code run through a shell (schema-designer-server.js:770, schema-designer-server.js:772, test-encryption-github.js:109)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Secrets never reach shell commands
2 secret values passed to shell commands — possible command injection
Never pass secrets through shell commands. Use library APIs that accept credentials as arguments.

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.
