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: Caution 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
ANTHROPIC_API_KEYAPI_KEYDATABASE_URLMY_API_KEYPOSTGRES_PASSWORDConfiguration, not credentials: MCPRESSO_LOG_LEVEL, MCPRESSO_MODEL, MCPRESSO_REGISTRY_DIR, MCPRESSO_SIMILARITY_THRESHOLD_ADAPT, MCPRESSO_SIMILARITY_THRESHOLD_SEED, POSTGRES_DB, POSTGRES_HOST, POSTGRES_PORT, POSTGRES_USER
Where it talks to
no vendor host named in the code
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 ANTHROPIC_API_KEY, API_KEY, DATABASE_URL, MY_API_KEY, POSTGRES_PASSWORD and talks to its vendor. 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 --net declared -- uvx mcpresso

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 79/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths; Access to sensitive file paths; Credential pass-through configuration. Summary: no network, touches nothing outside the project, writes no memory.
