Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
COOKIE_RPC_URLOptional | Cookie Chain RPC endpoint. Defaults to the public Cookiescan RPC (https://rpc.cookiescan.io). |
COOKIE_PRIVATE_KEYOptional, secret | Wallet key for money-moving tools (base58 secret, solana-keygen JSON array, or a path to a keypair file). Optional — without it the server runs read-only and money-moving tools return a clear error. The key is used only to sign locally and is redacted from all output. |
COOKIE_MAX_TRADE_COOKOptional | Hard per-transaction spend cap in COOK; money-moving tools refuse inputs valued above it (0 disables). Defaults to 100. |
COOKIE_SLIPPAGE_BPSOptional | Default slippage tolerance in basis points (500 = 5%). Defaults to 500. |
SOLANA_RPC_URLOptional | Solana mainnet RPC endpoint, used only by the bridge tool. Defaults to the public endpoint, which is rate-limited; a dedicated RPC is recommended for reliable bridging. |
