Add to ~/.codeium/windsurf/mcp_config.json.

Configuration

Variable	Required	Secret	Description
ZERODUST_API_URL	—	—	Custom API URL (defaults to https://api.zerodust.xyz)
ZERODUST_API_KEY	—	yes	API key for higher rate limits. An agent can issue itself one with the zerodust_register_api_key tool, with no human signup step.
ZERODUST_ALLOW_EXECUTE	—	—	Set to "true" to enable the sweep tools. Sweeping moves real funds, so it is off by default and also requires one of the four signing-key variables below.
ZERODUST_SIGNER_MODULE	—	—	Path or specifier of a module whose default export returns a viem LocalAccount. This is how Turnkey, Privy, AWS KMS or any other custody service is used, without a raw key ever reaching this server. Preferred over ZERODUST_PRIVATE_KEY.
ZERODUST_KEYSTORE_FILE	—	—	Path to an encrypted V3 keystore (as produced by `cast wallet import` or geth). Requires ZERODUST_KEYSTORE_PASSWORD_FILE or ZERODUST_KEYSTORE_PASSWORD.
ZERODUST_KEYSTORE_PASSWORD_FILE	—	—	Path to a file containing the keystore password, so the password never enters the MCP config.
ZERODUST_KEYSTORE_PASSWORD	—	yes	Keystore password inline. Prefer ZERODUST_KEYSTORE_PASSWORD_FILE.
ZERODUST_PRIVATE_KEY_FILE	—	—	Path to a file containing a hex private key, so the key stays out of the MCP config.
ZERODUST_PRIVATE_KEY	—	yes	Private key for the agent's own wallet, inline. Used locally to sign the EIP-7702 authorization and EIP-712 sweep intent; never transmitted, only the resulting signatures are sent. The signer-module, keystore and key-file options above keep it out of your config entirely.
ZERODUST_ALLOWED_DESTINATIONS	—	—	Comma-separated allowlist of sweep destinations. When unset, funds can only be swept to the agent's own address.
