Measured tools (7)

• list_chains read-only

  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.

  Parameters:

  • query — string — Optional name or slug filter, e.g. 'base' or 'zksync'.
  • evm_only — boolean — Only EVM chains.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_chain read-only

  One chain in detail: chain ID, live status and block height, and the HTTP, WebSocket and archive endpoint URL templates.

  Parameters:

  • chain (required) — string — Chain slug, name or chain ID, e.g. "eth", "Base", "4663".

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_pricing read-only

  SwiftNodes plans: flat monthly price, HTTP and WebSocket rate limits. No compute units, no per-request billing.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_method_support read-only

  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.

  Parameters:

  • method — string — e.g. 'trace_filter' or 'eth_getProof'.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• probe_endpoint read-only

  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.

  Parameters:

  • url (required) — string — Public http(s) RPC URL.
  • method — string
  • params — array

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• rpc_call read-only

  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.

  Parameters:

  • chain (required) — string — Chain slug, e.g. "eth", "base", "robinhood". See list_chains.
  • method (required) — string — e.g. "eth_blockNumber".
  • params — array — Method params, default [].
  • archive — boolean — Route to archive upstreams (paid plans).

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_account read-only

  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.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes
