list_chainsread-onlyList every blockchain SwiftNodes serves (one API key for all): name, slug, chain ID, live status, and whether WebSocket and archive (?archive=1) are available.
get_chainread-onlyOne chain in detail: chain ID, live status and block height, and the HTTP, WebSocket and archive endpoint URL templates.
get_pricingread-onlySwiftNodes plans: flat monthly price, HTTP and WebSocket rate limits. No compute units, no per-request billing.
get_method_supportread-onlyWhich JSON-RPC methods work on which chain, probed weekly through the customer request path. No args for the overview, or {method} for per-chain detail.
probe_endpointread-onlyDiagnose any public EVM JSON-RPC endpoint. With {url}: chain ID, block height, archive capability and latency. With {url, method, params}: makes that call and returns the result.
rpc_callread-onlyMake a JSON-RPC call on any SwiftNodes chain with the caller's API key (sent to this MCP server as 'Authorization: Bearer <key>'). Counts against that key's plan like any other request. Read-only: methods that send or sign transactions are refused.
get_accountread-onlyThe caller's SwiftNodes plan, rate limits, requests used this month, and the IP/origin restrictions on the key in use. Needs 'Authorization: Bearer <key>'. Never returns key values.
