Overview

Description from the maker (original English)

Decentralized AI inference (weather, deepfake detection, LLMs) with x402 USDC micropayments.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other
  • You need to fill in: TELEGRAPH_NODE_URL, TELEGRAPH_ENGINE_URL, TELEGRAPH_DAEMON_URL, TELEGRAPH_EVM_PRIVATE_KEY, TELEGRAPH_SOLANA_PRIVATE_KEY

Install

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

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: TELEGRAPH_NODE_URL, TELEGRAPH_ENGINE_URL, TELEGRAPH_DAEMON_URL, TELEGRAPH_EVM_PRIVATE_KEY, TELEGRAPH_SOLANA_PRIVATE_KEY, EVM_NETWORK, SVM_NETWORK, REFRESH_INTERVAL_MS

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

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

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

{
  "mcpServers": {
    "telegraph": {
      "command": "npx",
      "args": [
        "-y",
        "telegraph-protocol-mcp"
      ],
      "env": {
        "TELEGRAPH_NODE_URL": "your-value",
        "TELEGRAPH_ENGINE_URL": "your-value",
        "TELEGRAPH_DAEMON_URL": "your-value",

        "SVM_NETWORK": "your-value",
        "REFRESH_INTERVAL_MS": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add telegraph --env TELEGRAPH_NODE_URL=your-value --env TELEGRAPH_ENGINE_URL=your-value --env TELEGRAPH_DAEMON_URL=your-value --env TELEGRAPH_EVM_PRIVATE_KEY=your-value --env TELEGRAPH_SOLANA_PRIVATE_KEY=your-value --env EVM_NETWORK=your-value --env SVM_NETWORK=your-value --env REFRESH_INTERVAL_MS=your-value -- npx -y telegraph-protocol-mcp

Common questions

Is Telegraph 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: TELEGRAPH_NODE_URL, TELEGRAPH_ENGINE_URL, TELEGRAPH_DAEMON_URL, TELEGRAPH_EVM_PRIVATE_KEY, TELEGRAPH_SOLANA_PRIVATE_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, dotnet-mcp

Telegraph MCP server

Gives any MCP client (Claude Code, Claude Desktop, Cursor, Goose, Continue, ElizaOS, LangChain, ...) the Telegraph network: ask questions that the best-ranked miner answers, browse every intent, miner and ranking, and pay per ask in USDC from escrow or by x402. One setting, nine tools.

Quick start

You need Node 18+ and, for paid asks, the private key of a wallet made for this (never your main wallet). Free tools work without a key.

Claude Code

claude mcp add telegraph -e TELEGRAPH_PRIVATE_KEY=0xyour_key -- npx -y @telegraphprotocol/telegraph-protocol-mcp

Claude Desktop, Cursor and most other clients (claude_desktop_config.json, ~/.cursor/mcp.json, ...)

{

"mcpServers": { "telegraph": { "command": "npx", "args": ["-y", "@telegraphprotocol/telegraph-protocol-mcp"], "env": { "TELEGRAPH_PRIVATE_KEY": "0xyour_key" } } } }

Then ask your agent things like "what is the BTC price?", "which miners serve weather and how do they rank?" or "how much is in my Telegraph escrow?". More client configs are in examples/.

Settings

VariableDefaultWhat it is
TELEGRAPH_PRIVATE_KEYnoneWallet that pays for asks. Without it only the free tools work. (TELEGRAPH_EVM_PRIVATE_KEY, the v1 name, also works.)
TELEGRAPH_URLhttps://devnode.telegraphprotocol.comThe node (Telegraph beta 2)
TELEGRAPH_PAYMENTautoauto: escrow first, then x402. escrow or x402: only that one
TELEGRAPH_RPC_URLpublic Sepolia RPCChain RPC, for the balance and deposit tools
TELEGRAPH_DIAMOND, TELEGRAPH_CHAIN_IDbeta 2'sThe contract that holds escrow, and its chain

Tools

ToolCostWhat it does
telegraph_ask~$0.01Ask a question (optionally an exact intent and params); the node routes it to the top live miner
telegraph_ask_minerthe miner's priceAsk one miner you choose, or call one of its endpoints directly
telegraph_find_intentsfreeSearch the 130+ intents (kinds of question)
telegraph_intentfreeOne intent's kind, params, answer fields and top miners
telegraph_find_minersfreeAn intent's miners with rank, score, price and endpoints, or a word search over all miners
telegraph_rankingfreeThe latest epoch's ranking, per intent
telegraph_accountfreeWallet USDC and ETH, and the escrow balance, debt and pending withdrawal
telegraph_depositgasMove wallet USDC into escrow (approve + depositUSDC)
telegraph_docsfreeBuilt-in guides: getting started, payments, intents and ranking, errors. Also served as MCP resources (telegraph://docs/...)

Payments

  • Escrow (used first): deposit USDC once with telegraph_deposit. Each ask carries a signature that proves intent but can't move funds. Asks are deducted at the epoch close, and a failed ask is never billed.
  • x402 (fallback): when escrow is empty, the server pays each ask from the wallet's USDC. If the ask then fails, the node credits the payment to your escrow, so it stays yours.

Details, debt and withdrawing: guides/2-payments.md.

Test funds (beta 2)

Beta 2 runs on Ethereum Sepolia. Its USDC (0xcc194e1a843B658526D0D5C431f670028582Ae17) is a test token anyone can mint with mint(yourAddress, amount) (6 decimals). Gas needs a little Sepolia ETH from a public faucet.

Security

  • Use a wallet made for this, holding only what you plan to spend.
  • The key stays in the MCP server process; the agent never sees it.
  • The server runs locally over stdio and opens no port.

Development

npm install && npm run build

node scripts/smoke.mjs # free tools against the node TELEGRAPH_PRIVATE_KEY=0x... node scripts/smoke.mjs paid # plus three asks (~$0.03) node scripts/smoke.mjs call telegraph_intent '{"intent":"CRYPTO_PRICE_USD"}' npx @modelcontextprotocol/inspector dist/index.js # browse the tools
