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.

// key findings
🚨
Secret credentials may flow to a network call
1 flow detected: CDISC_API_KEY. We can’t prove the destination matches the brand the credential belongs to.
⚠️
Known vulnerabilities in dependencies: 1 high
Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.
🔐
You'll be asked for 1 credential: CDISC_API_KEY
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// known CVEs in dependencies1 high1 low

Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

high@modelcontextprotocol/sdk@0.6.0GHSA-w48q-cv73-mx4w

Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default

lowyaml@2.5.0GHSA-48c2-rrv3-qjmp

yaml is vulnerable to Stack Overflow via deeply nested YAML collections

// environment variables
To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.
configCDISC_API_BASE_URL(optional): override server base URL, default https://api.library.cdisc.org
🔐 secretCDISC_API_KEYexport =your_key_here
configCDISC_AUTH_HEADER(optional): header name when using header auth, default api-key
configCDISC_AUTH_LOCATIONexport =header # or: query
configCDISC_AUTH_QUERY(optional): query param name when using query auth, default api-key
configCDISC_CACHE_DEBUG(optional): set to 1 to log cache/retry activity to stderr.
configCDISC_CACHE_ENABLED(optional): set to 0 to disable caching. Default: enabled.
configCDISC_CACHE_EXCLUDE_REGEX(optional): regex to exclude cache matches; defaults also exclude search/suggest.
configCDISC_CACHE_INCLUDE_REGEX(optional): regex to force-include cache matches.
configCDISC_CACHE_MAX_ENTRIES(optional): max cache entries (LRU). Default: 500.
configCDISC_CACHE_PERSIST_PATH(optional): file path to persist cache to disk (JSON). Default: disabled.
configCDISC_CACHE_TTL_MS(optional): TTL for GET responses in milliseconds. Default: 60000.
configCDISC_OPENAPI_DIR(optional): directory for OpenAPI YAML; defaults to server/openapi. The manifest.json sets this to ${DXT_DIR}/server/openapi when packaged as DXT so the extension is self‑contained.
configCDISC_RETRY_BACKOFF_MS(optional): base backoff per attempt in ms. Default: 300.
configCDISC_RETRY_COUNT(optional): number of retries for transient 5xx/network errors. Default: 2.

Tool 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

19/19 tools missing one or more hints — list_operations (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cache.clear (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cache.invalidate (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +16 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.

Secrets stay with their owner

1 secret/sensitive value flow into network calls (CDISC_API_KEY → dynamic)

Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.

Secrets not logged

5 secret values sent to console.log

Redact or omit secret values from log output.

Production dependencies are patched

0 critical, 1 high severity in production deps — @modelcontextprotocol/sdk@0.6.0 (high), yaml@2.5.0 (low)

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)

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 6 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
