Common questions about connecting and running Halfkey Obol.
What is Obol and how does it work with Claude?
Obol is an MCP server that connects Claude to Solana blockchain operations via an x402 payment gateway. It provides wallet management, token queries, DeFi interactions, and swap execution—you pay per request through the gateway.
How do I set up the Obol MCP server?
Install via `npx obol-mcp@2.0.1` and configure the `OBOL_URL` environment variable to point to your Obol API instance. The server communicates over stdio with your MCP client.
What wallet and token operations can I perform?
You can check wallet balances, list token holdings, query token prices and liquidity, and execute swaps. All operations are routed through the Obol gateway and billed per request.
How is pricing structured?
Obol uses x402 pay-per-request pricing—you're charged for each transaction or query executed through the gateway. Exact rates depend on your Obol API instance configuration.
Can I use Obol with a custom Solana RPC?
Yes, the `OBOL_URL` environment variable lets you point to a custom Obol API instance, which can be configured to use your preferred Solana RPC endpoint.
