mcpuniverse@1.1.3

VERIFIED· not started

Publisher claims: "A framework for developing and benchmarking AI agents using Model Context Protocol (MCP)" Observed in sandbox: no network, touches nothing outside the project, writes no memory.

Coverage

Not started: dependency install failed; the server itself was not observed.
Tested
the dependency install step · every file read, file written and host contacted by what ran
Not tested
server startup · the tool list · tool behavior

What this means for the label: Verified here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.

Where it talks to
no vendor host named in the codeAlso arxiv.org, tiangolo.com, deepseek.com, mistral.ai, openrouter.ai — not the publisher's domain; check what for before connecting.
What the honeypot saw
no credential files read · no network
What we could not test
server startup · the tool list · tool behavior

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names arxiv.org, tiangolo.com, deepseek.com, mistral.ai, openrouter.ai as well as its own vendor. The guard injects ACCESS_TOKEN_DURATION_HRS, ANTHROPIC_API_KEY, DEEPSEEK_API_KEY, GEMINI_API_KEY, LOCAL_LLM_API_KEY, MISTRAL_API_KEY, OPENAI_API_KEY, OPENROUTER_API_KEY, TOKEN_SYMMETRIC_KEY, VLLM_API_KEY, XAI_API_KEY only into requests to the host you bind (and its subdomains) and refuses the rest.

Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; not started: dependency install failed; the server itself was not observed) on 2026-11-11 and scored it 88/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.
