CAUTION· not started

Publisher claims: "Agent-feels-local SSH orchestration MCP server — persistent bash, hash-protected editing, SFTP, tunnels, multi-host orchestration over AsyncSSH" Observed in sandbox: no network, touches nothing outside the project, writes no memory.

What would fix thisWatchDispute verdict

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
GITHUB_TOKENPORTAL_AUTH_TOKENPORTAL_CREDENTIAL_AGENT_SOCKETConfiguration, not credentials: PORTAL_ALLOW_LOCAL_EXEC, PORTAL_ALLOW_TUNNEL_EXPOSURE, PORTAL_BASH_HEARTBEAT_INTERVAL, PORTAL_JOB_MAX_LIVE, PORTAL_JOB_PERSIST, PORTAL_JOB_STATE_FILE, PORTAL_JOB_TTL, PORTAL_LOGIN_SHELL, PORTAL_MAX_TIMEOUT, PORTAL_SSH_CONFIG, PROGRAMDATA, XDG_RUNTIME_DIR
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 GITHUB_TOKEN, PORTAL_AUTH_TOKEN, PORTAL_CREDENTIAL_AGENT_SOCKET 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 portal-mcp-server

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

Is [email protected] safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; not started: dependency install failed; the server itself was not observed) on 2026-11-14 and scored it 62/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Privileged sudo command; Access to sensitive file paths; Privileged sudo command. Summary: no network, touches nothing outside the project, writes no memory.
