Use (mcp-use) MCP Server
mcp-use
npm
v1.34.5
Source verified
Published by mcp-use — publish provenance cryptographically ties this package to that repository. That is proof of origin, not an official vendor package.
Started at 100 and nothing was deducted: the deterministic scan raised no scored threat in the published surface it inspected. Capability observations and advisory notes are recorded but never lower the score.
Findings 7
high Dynamic code execution in server code (dist/src/server/tools/tool-registration.d.ts)MTC-SRC-001
In the server's implementation (`dist/src/server/tools/tool-registration.d.ts:79`): 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: eval(
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.

high Shell/command execution in server code (dist/src/auth/index-node.cjs)MTC-SRC-002
In the server's implementation (`dist/src/auth/index-node.cjs:781`): Spawning a shell/process is command-execution capability; with unsanitized tool input it is command injection / RCE. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: child_process
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.

high Shell/command execution in server code (dist/src/auth/index-node.js)MTC-SRC-002

medium Dynamic module load from a non-literal (dist/chunk-YH33JHUI.js)MTC-SRC-005
In the server's implementation (`dist/chunk-YH33JHUI.js:1036`): Loading a module chosen at runtime (from a variable) can pull in and run attacker-influenced code paths. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: import(providerConfig.package)

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 |
|---|---|---|---|---|
v1.34.5 latest |
A 100/100 | 7 | 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.
