Is Adeu MCP server safe?
- Node.js shell/command execution
- Node.js filesystem write/delete
- MCP tool surface detected
What to do: Nothing here argues against installing it. Grant the capabilities it lists only if you expect the tool to need them.
Adeu MCP server is an npm package analyzed by SkillTotal's deterministic static scanner. The scan found no malicious indicators. It can: filesystem write, mcp tools detected and shell execution — capabilities are what the code can do, not a verdict on intent. Risk score 0/100 (low).
@adeu/mcp-server 3.0.7
Automated static-analysis result. It can contain false positives and false negatives, and is not a claim about the intent of Adeu MCP server's authors. Report a false positive.
Behavioral traits
How this component maps to the CSA agentic threat model. Descriptive — it never affects the risk score.
Findings (3)
The component can run operating-system commands or spawn processes.
import { execSync } from "node:child_process";gitSha = execSync("git rev-parse --short HEAD", { encoding: "utf-8" }).trim();Why it matters: Powerful and often legitimate — confirm the commands aren't built from untrusted input.
Fix: Confirm the command and its arguments are fully controlled and not derived from untrusted input; prefer execFile with an argument array.
The component writes or deletes files on disk.
fs.writeFileSync(outPath, outBuf);
fs.writeFileSync(outPath, outBuf);
fs.writeFileSync(outPath, result.outBuffer);
fs.writeFileSync(outPath, result.out_bytes);
fs.writeFileSync(e.unverified_path, e.unverified_bytes);
fs.writeFileSync(outPath, outBuf);
fs.writeFileSync(outPath, outBuf);
fs.writeFileSync(outPath, result.outBuffer);
fs.writeFileSync(outPath, result.out_bytes);
fs.writeFileSync(e.unverified_path, e.unverified_bytes);
Why it matters: Usually legitimate, but worth confirming the paths can't be controlled by untrusted input.
Fix: Confirm which files are written/deleted and that paths cannot be influenced by untrusted input.
An MCP tool surface (manifest or tool definitions) was found.

Why it matters: Just context — review which tools it offers and their permissions.
Fix: Review the declared MCP tools and their permissions.
