Is External Agents safe and trustworthy?

tashan scores External Agents on public evidence — tashan score 67.0/100, it is currently active, note: a single primary maintainer (bus-factor risk), no known advisories against the current release, it runs a script at install time. Audit scope: OSV advisories, install-time scripts, build provenance and declared permission surface. We do not review source code or execute the capability.

How do I install External Agents?

In Claude Code: run `claude mcp add mrrlin-dev-external-agents -- npx -y @mrrlin-dev/external-agents`. In Cursor / Claude Desktop, add it to mcp.json / claude_desktop_config.json.

installable: each client documents how to load an MCP server of this type — that is the client's promise, not a claim verified against this capability

Security audit

Every finding is shown in full — which advisory, the version that fixes it, and the exact command run at install time. Nothing in this audit is behind a licence.

No known advisoriesclearchecked against OSV for 0.61.1 — this package, not its dependency tree

Runs a script at install timecodenode scripts/postinstall-banner.mjs || true

No access inferred from declared dependenciesnothing it depends on reaches files, shell or network. This reads declarations only — built-in APIs are invisible to it, so absence of a declaration is not absence of access
