The publisher's own command. Not a PlugMCP endpoint.
Host a copy with our keys and logs.
Local command
docker run -i --rm ghcr.io/joshuawowk/signal-mcp:1.0.1Credentials from the publisher
- SIGNAL_SENDER — E.164 number of the account registered in signal-cli (e.g. +15555550100)
- SIGNAL_DEFAULT_RECIPIENT — E.164 number messaged by default; tools accept a per-call recipient override
- SIGNAL_RPC_URL — signal-cli HTTP JSON-RPC endpoint as seen from the container. The server's built-in default is http://127.0.0.1:8080/api/v1/rpc (use with --network host on Linux); this listing defaults to the Docker host alias.
- SIGNAL_TCP_HOST — signal-cli daemon TCP host, used only for the receive-path health check
- SIGNAL_TCP_PORT — signal-cli daemon TCP port (daemon started with --tcp), used only for the receive-path health check
- SIGNAL_INBOX_PATH — Path of the replies inbox file inside the container (populated only by the subscriber process)
- SIGNAL_POLL_INTERVAL — Subscriber poll cadence in seconds
- SIGNAL_INBOX_RETENTION_DAYS — Days of replies kept in the inbox file
