Tools

get_account
The 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.
shallow
get_chain
One chain in detail: chain ID, live status and block height, and the HTTP, WebSocket and archive endpoint URL templates.
shallow
get_method_support
Which 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.
shallow
get_pricing
SwiftNodes plans: flat monthly price, HTTP and WebSocket rate limits. No compute units, no per-request billing.
shallow
list_chains
List every blockchain SwiftNodes serves (one API key for all): name, slug, chain ID, live status, and whether WebSocket and archive (?archive=1) are available.
shallow
probe_endpoint
Diagnose 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.
shallow
rpc_call
Make 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.
