What the code does

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

        r = subprocess.run(["git", "--no-pager", "-c", "core.fsmonitor=", "-c", "core.hooksPath=/dev/null"] + args,

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Put your own value in place of <SYMBOL_NODE_URL> (REST URL of the Symbol node to query, e.g. https://<node-host>:3001; https:// is required (http:// only for localhost / 127.0.0.1 / [::1]) and the port is used exactly as given). The author’s registry entry marks it as required.

Optional settings from the registry entry, left out of the block above: SYMBOL_NETWORK (mainnet or testnet; when set, start-up fails if the node reports a different network), SYMBOL_TIMEZONE (IANA zone such as Asia/Tokyo that adds a local time next to every UTC timestamp), SYMBOL_REFERENCE_NODES (Comma-separated https:// node URLs that symbol_network_compare and symbol_version_drift check against; no other host is ever contacted), SYMBOL_REQUEST_TIMEOUT_MS (Per-request timeout in milliseconds, 100 to 600000 (default 10000)), SYMBOL_STATE_DIR (Absolute directory where symbol_harvesting_status keeps one snapshot file per node (unlocked harvester public keys, heights and times; no secrets) when it is asked to compare or save, created on first save with mode 0700; when unset, the tool reports the current list without a comparison).
