Install & configure

Prerequisites

required
Solana and Base private keys
Local wallet private keys for both chains

Install in your client

Paste into the AI you're chatting with — it will figure out the rest

Please install the `clawswap` MCP server into my current AI client (that's you).

Required prerequisites (do these first if not already done):
- **Solana and Base private keys** — Local wallet private keys for both chains

Canonical MCP server config (stdio transport):
- command: `npx`
- args: ["-y","@clawswap/mcp-server"]
- required environment variables:
  - `SOLANA_PRIVATE_KEY`: Base58-encoded Solana private key (example: `<your-solana-private-key>`)
  - `BASE_PRIVATE_KEY`: 0x-prefixed hex Base (EVM) private key (example: `<your-base-private-key>`)

Note: Cross-chain token send/swap/bridge between Solana and Base. Gasless. Handles quote → sign → submit → settlement.

Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.

Note: Cross-chain token send/swap/bridge between Solana and Base. Gasless. Handles quote → sign → submit → settlement.
