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.

Before you give it your token

It will ask for
MCP_AUTH_TOKENNACOS_PASSWORDConfiguration, not credentials: MCP_HOST, MCP_LOG_LEVEL, MCP_PORT, MCP_STATELESS_HTTP, MCP_TRANSPORT, NACOS_BASE_URL, NACOS_INSECURE, NACOS_NAMESPACE, NACOS_READ_ONLY, NACOS_USERNAME, NACOS_VERSION
Where it talks to
nacos.io (its own)
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. It asks for MCP_AUTH_TOKEN, NACOS_PASSWORD and talks to nacos.io. Give the credential to the guard, not the server: the value never enters the server's environment and only travels to the host you bind. What the tools do with a real credential was not observed.

$vet-skills run --secrets MCP_AUTH_TOKEN=nacos.io,NACOS_PASSWORD=nacos.io -- uvx mcp-nacos

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 2026-11-08 and scored it 92/100 (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.
