# SwiftNodes RPC

> Blockchain RPC for 125+ chains: endpoints, method support, probing and RPC calls with your key.

**An agent can connect right now, no human step.** Remote endpoint, no authentication, reachable on the last probe.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "swiftnodes": {
      "type": "http",
      "url": "https://rpc.swiftnodes.io/mcp",
      "headers": {
        "Authorization": "Bearer ${SWIFTNODES_TOKEN}"
      }
    }
  }
}
```

Placeholders to fill: `${SWIFTNODES_TOKEN}`.

## Trust

- hygiene: 100
- liveness: 100
- freshness: 100
- provenance: 100
- drivers: +repository +namespace-matches-repo +dns-namespace +website +reachable +uptime-100% +updated-5d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 89/100 (new)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 7 of 7 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 736 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 5 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: deps.dev does not know swiftnodes-mcp@0.2.0

- tools: 7, about 736 tokens to load them all
- tool set hash: e98b308ac14f911f3577c037bd24a241
- tools last changed: 2026-10-15T17:58:50.427Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.swiftnodes/swiftnodes.svg)](https://protogrid.dev/servers/io.swiftnodes/swiftnodes)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-15 `get_account` changed (annotations)
- 2026-10-15 `rpc_call` changed (description, annotations)
  - before: 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.
  - after: 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.

## Dependencies

- npm swiftnodes-mcp@0.2.0: unknown

Dependency graphs from deps.dev; advisories from OSV.dev, including the GitHub Advisory Database and the PyPI Advisory Database; all CC BY 4.0.

## Remotes

- https://rpc.swiftnodes.io/mcp (streamable-http, auth none, reachable true, uptime30d 1)

## Packages

- npm swiftnodes-mcp@0.2.0

## Tools (7)

- `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.
- `get_chain`: One chain in detail: chain ID, live status and block height, and the HTTP, WebSocket and archive endpoint URL templates.
- `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.
- `get_pricing`: SwiftNodes plans: flat monthly price, HTTP and WebSocket rate limits. No compute units, no per-request billing.
- `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.
- `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.
- `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.
