Coverage

Startup only; authenticated tool behavior not tested.
Tested
server startup over stdio (initialize sent) · every file read, file written and host contacted by what ran
Not tested
the tool list (the server exited before answering) · what the tools do when called with real credentials

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.

Connect it with a scoped credential, under the guard. It asks for ACCESS_TOKEN_TTL_SECONDS, AUTH_ALLOW_ALL_USERS, AUTH_ALLOWED_GITHUB_IDS, AUTH_ALLOWED_GITHUB_LOGINS, AUTH_ALLOWED_GOOGLE_EMAILS, AUTH_ALLOWED_GOOGLE_SUB_IDS, AUTH_CODE_TTL_SECONDS, CONTROL_PLANE_SIGNING_KEY_PATH, DATABASE_URL, ENROLLMENT_TOKEN_TTL_SECONDS, GITHUB_CLIENT_SECRET, GOOGLE_CLIENT_SECRET, JWT_SIGNING_KEY_PATH, OAUTH_DCR_MAX_CLIENTS, SSH_AUTH_SOCK, SSH_MCP_CONNECTOR_CREDENTIAL_COMMAND, SSH_MCP_CONNECTOR_CREDENTIAL_COMMAND_ARGS, SSH_MCP_CONNECTOR_CREDENTIAL_COMMAND_TIMEOUT_MS, SSH_MCP_CONNECTOR_CREDENTIAL_PROVIDER, SSH_MCP_HTTP_AUTH_MODE, SSH_MCP_HTTP_BEARER_TOKEN, SSH_MCP_HTTP_BEARER_TOKEN_FILE, SSH_MCP_OAUTH_ALLOWED_ALGORITHMS, SSH_MCP_OAUTH_AUDIENCE, SSH_MCP_OAUTH_ISSUER, SSH_MCP_OAUTH_JWKS_URL, SSH_MCP_OAUTH_REQUIRED_SCOPES, SSH_MCP_OAUTH_RESOURCE, SSHAUTOMATOR_DATABASE_URL 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.

Is [email protected] safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; startup only; authenticated tool behavior not tested) on 2026-11-12 and scored it 76/100 (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; Privileged sudo command; Privileged sudo command. Summary: no network, touches nothing outside the project, writes no memory.
