Environment variable descriptions (raw)MCP_BRIDGE_ALLOWED_HOSTS=Comma-separated hostname allowlist for outbound paid requests. When set, any other host is refused before a request is signed. · MCP_BRIDGE_ALLOWED_PAYTO=Comma-separated payee allowlist. When set, any payment whose payTo address is not listed is refused. · MCP_BRIDGE_ALLOW_HTTP=Set to 1 to allow http:// targets (local development only). https is enforced otherwise. · MCP_BRIDGE_BATCH_DEPOSIT_MULTIPLIER=How many request-amounts to deposit at once when opening an EVM batch-settlement channel. · MCP_BRIDGE_BAZAAR_URL=x402 Bazaar discovery endpoint. Override to point at a self-hosted or alternative bazaar. · MCP_BRIDGE_DISCOVER_LIMIT=Max number of x402 Bazaar resources to register as dynamic tools at startup. Set 0 to disable discovery. · MCP_BRIDGE_EVM_PRIVATE_KEY=0x-prefixed 32-byte hex private key that funds USDC payments on EVM chains (Base, Arbitrum, …). At least one of the EVM/SVM keys is required. Treat like cash — use a dedicated low-balance wallet. · MCP_BRIDGE_MAX_DEPOSIT_ATOMIC=Hard cap in atomic units on a single batch-settlement channel deposit or top-up. · MCP_BRIDGE_MAX_PRICE_PER_CALL_ATOMIC=Per-call spending cap in atomic units (USDC has 6 decimals). Payments above this abort with a clear reason. · MCP_BRIDGE_MAX_TOTAL_ATOMIC=Cumulative session spending ceiling in atomic units. Once total spend would exceed it, further payments abort until restart. · MCP_BRIDGE_SVM_PRIVATE_KEY=Solana secret key that funds USDC payments: base58 64-byte secret key (Phantom / solana-keygen format) or a JSON array of 64 integers. At least one of the EVM/SVM keys is required. Treat like cash. · RPC_URL_8453=Per-chain RPC override, one variable per chain id (RPC_URL_<chainId>, e.g. RPC_URL_8453 for Base). Defaults to viem's public RPC for that chain. · X402_MCP_BRIDGE_CHANNELS_DIR=Directory for persisted batch-settlement channel state (survives client restarts).
