You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Or run it on your computer

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "swiftnodes": {
      "command": "npx",
      "args": [
        "-y",
        "swiftnodes-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add --transport http swiftnodes https://rpc.swiftnodes.io/mcp --header 'Authorization: your-value'

Or run it on your computer

claude mcp add swiftnodes -- npx -y swiftnodes-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "swiftnodes": {
      "url": "https://rpc.swiftnodes.io/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Or run it on your computer

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "swiftnodes": {
      "command": "npx",
      "args": [
        "-y",
        "swiftnodes-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "swiftnodes": {
      "type": "http",
      "url": "https://rpc.swiftnodes.io/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Or run it on your computer

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "swiftnodes": {
      "type": "stdio",
      "command": "npx",
      "args": [

Common questions

Is SwiftNodes RPC safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 22 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

swiftnodes-mcp

An MCP (Model Context Protocol) server for SwiftNodes — multi-chain blockchain RPC, exposed to AI agents.

One API key, 125+ chains, flat-rate pricing. This server gives Claude, ChatGPT, Cursor, and any MCP client live, factual answers about chains, pricing, and JSON-RPC method support — plus the ability to probe any EVM endpoint directly.

Chains

Works across all 128 SwiftNodes chains, including Ethereum, BNB Smart Chain (BSC), opBNB, Base, Arbitrum, Polygon, Solana and Bitcoin. Each chain has a slug used in tool arguments and endpoint URLs, for example:

Chain	Slug	Endpoint
BNB Smart Chain (BSC)	`bsc`	`https://rpc.swiftnodes.io/rpc/bsc?key=YOUR_API_KEY`
opBNB	`opbnb`	`https://rpc.swiftnodes.io/rpc/opbnb?key=YOUR_API_KEY`
Ethereum	`eth`	`https://rpc.swiftnodes.io/rpc/eth?key=YOUR_API_KEY`
Base	`base`	`https://rpc.swiftnodes.io/rpc/base?key=YOUR_API_KEY`

Example prompts: "Which JSON-RPC methods does BNB Smart Chain support?", "What is the latest block on opBNB?", "Is trace_filter available on BSC?". list_chains returns the full list.

Hosted server (recommended)

SwiftNodes runs this server for you at `https://rpc.swiftnodes.io/mcp` (Streamable HTTP). Nothing to install.

claude mcp add --transport http --scope user swiftnodes https://rpc.swiftnodes.io/mcp --header "Authorization: Bearer $SWIFTNODES_API_KEY"

Cursor and other clients (~/.cursor/mcp.json):

{ "mcpServers": { "swiftnodes": { "url": "https://rpc.swiftnodes.io/mcp", "headers": { "Authorization": "Bearer YOUR_API_KEY" } } } }

The key is optional: without it the public tools below work. With it, two more tools are available:

Tool	What it does
`rpc_call`	Make a JSON-RPC call on any SwiftNodes chain with your key (counts against your plan like any request).
`get_account`	Your plan, rate limits, requests used this month, and the IP/origin restrictions on the key. Never returns key values.

Listed in the official MCP Registry as io.swiftnodes/swiftnodes. Docs: https://swiftnodes.io/docs/mcp

Tools

Tool	What it does
`list_chains`	Every chain SwiftNodes serves — name, slug, chain ID, category, docs page. Filterable.
`get_chain`	Full detail for one chain: IDs, block time, native currency, HTTP/WebSocket/archive endpoint templates, docs links.
`get_pricing`	Live flat-rate plans from the public API — rate limits, included features, no compute units.
`get_method_support`	Which JSON-RPC methods work on which chain — auto-probed weekly through the same path customer requests take. Overview or per-method detail.
`probe_endpoint`	Diagnose any EVM JSON-RPC endpoint (ours or anyone's): chain identity, block height, archive capability, latency — or run a specific method call.

Run it locally (stdio)

Zero dependencies, Node >= 18.

From this repo:

git clone https://github.com/swiftnodes/swiftnodes-mcp

node swiftnodes-mcp/bin/server.js # speaks MCP over stdio

Via npm (once published): npx -y swiftnodes-mcp

Claude Desktop

"mcpServers": { "swiftnodes": { "command": "node", "args": ["/path/to/swiftnodes-mcp/bin/server.js"] } } }

Cursor / any MCP client

Add a stdio server with command node and args ["/path/to/swiftnodes-mcp/bin/server.js"].

Data sources

Chains — bundled snapshot generated from the SwiftNodes site source of truth (scripts/generate-chains-data.mjs; regenerate after chain changes).
Pricing — fetched live from https://rpc.swiftnodes.io/api/plans (bundled fallback if unreachable).
Method support — fetched live from https://swiftnodes.io/method-matrix.json, re-probed weekly. Support values reflect the real customer path, including failover.

Notes

probe_endpoint will call any http(s) URL you give it — the same ground our CLI diagnostic rpc-doctor covers. Probe responsibly: one quick pass per endpoint, not a load test.
