Web Docs (cosmocoder) MCP Server

npm
v2.0.22
Source verified
Published by cosmocoder — publish provenance cryptographically ties this package to that repository. That is proof of origin, not an official vendor package.
Crawls and indexes web documentation from any website.
Every server starts at 100. These are the exact deductions the deterministic engine applied — each one reproducible, none of it an opinion or an LLM's guess:
| Points | What was found | Category |
|---|---|---|
| −22 | Hardcoded JSON Web Token in server code MTC-SRC-008 | exfiltration |
| −6.3 | Package runs install-time scripts MTC-SUP-010 | supply-chain |
Grade capped: 1 confirmed high finding → grade capped at C. A hard gate overrides the point total — no amount of clean surface buys back a confirmed catastrophe.
Capability observations and info notes are shown under Findings but never scored.

Findings 3
high Hardcoded JSON Web Token in server code (build/util/security.test.js)MTC-SRC-008
A live-looking JSON Web Token is hardcoded in `build/util/security.test.js:243`. Secrets in source ship to everyone who installs the package and are a direct credential leak.
Evidence: JSON Web Token: eyJh…(redacted)
Fix: Remove the secret, rotate it, and load credentials from the environment or a secret store.
Location: server build/util/security.test.js
high Dynamic code execution in server code (build/crawler/crawlee-crawler.js)MTC-SRC-001
In the server's implementation (`build/crawler/crawlee-crawler.js:225`): Evaluating strings as code is the most direct RCE primitive; if any tool input reaches it, the server executes attacker-chosen code. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: new Function(
Fix: Review this call path: confirm it never receives unsanitized tool input, constrain it, or remove it. Treat a server whose code reaches these sinks as high-capability regardless of what its tools claim.
Location: server build/crawler/crawlee-crawler.js
medium Package runs install-time scripts (postinstall)MTC-SUP-010
"@cosmocoder/mcp-web-docs" executes postinstall script(s) at install time. The large majority of malicious packages abuse install hooks to run code before you ever import them.
Fix: Review the scripts; install with --ignore-scripts where possible and vet what they do.
Location: package @cosmocoder/mcp-web-docs
What this scan could not see
- No tools were enumerated, so prompt-injection, capability and toxic-flow analysis had no tool surface to inspect. To grade a package’s real runtime tools, scan the running server: --command "npx -y <package>".
Versions
Scan history per published version. The engine is deterministic — the same version always yields the same score, so a changed score means the package itself changed.
| Version | Score | Findings | Engine | Scanned |
|---|---|---|---|---|
v2.0.22 latest |
C 72/100 | 3 | 1.5.0 | 2026-07-22 |
Embed this score
Show this server's live Trust Score in your README, docs or website. The badge is served straight from the registry and updates automatically after every rescan — no API key needed. It links back to this page, so anyone who sees the grade can also read the findings behind it instead of taking a number on faith.
Verify this score yourself
The score above is reproducible: the same package version always yields the same result. Run it locally or over the free API — no account, no LLM, fully deterministic.
