pyunto-agent@0.3.0

VERIFIED· not started

Publisher claims: "Make an external agent (Claude, Claude Code, any CLI/HTTP agent) the partner of a Pyunto exchange diary" 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

Not tested

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
ANTHROPIC_API_KEYPYUNTO_AGENT_SECRETPYUNTO_PASSWORDConfiguration, not credentials: PYUNTO_AGENT_DIR, PYUNTO_AGENT_LISTEN, PYUNTO_AGENT_NAME, PYUNTO_BACKEND, PYUNTO_BACKEND_URL, PYUNTO_BASE_URL, PYUNTO_COMMAND, PYUNTO_EMAIL, PYUNTO_HISTORY, PYUNTO_MODEL, PYUNTO_PERSONA
Where it talks to
no vendor host named in the codeAlso pyunto.com — 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 pyunto.com as well as its own vendor. The guard injects ANTHROPIC_API_KEY, PYUNTO_AGENT_SECRET, PYUNTO_PASSWORD only into requests to the host you bind (and its subdomains) and refuses the rest.

$vet-skills run --net declared -- uvx pyunto-agent

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 2026-11-13 and scored it 85/100 (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.
