Hyperd MCP

hyperD MCP Server

Exposes 24 paid hyperD x402 tools — 17 data/risk endpoints, 6 premium synthesis verdicts ($0.30–$1.50), and a multi-call bundle — plus 3 free meta tools (and 3 watch tools when enabled) from api.hyperd.ai. Drop into Claude Desktop, Cursor, Cline, Zed, or any MCP-compatible client.

What it does

Each tool call:

1. Sends a request to the corresponding api.hyperd.ai endpoint
2. Receives an HTTP 402 with payment requirements
3. Signs an EIP-3009 USDC transfer authorization with your wallet
4. Retries with the payment header
5. Returns the data to the AI assistant

You pay $0.005–$1.50 in USDC on Base per call — data/risk endpoints $0.005–$0.10, premium synthesis verdicts $0.30–$1.50. No subscription. No accounts.

Try it free

First 5 calls per IP per 24h are free — no wallet, no signup, no API key. Just curl:

curl "https://api.hyperd.ai/api/balance?address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"

Lifetime cap: 10 calls per IP. After that (or when daily quota is exhausted), the endpoint returns HTTP 402 — sign a small EIP-3009 USDC payment on Base via the Python SDK or TypeScript MCP server. The premium synthesis tier ($0.30+) always requires payment — it is not free-tier eligible.

/api/wallet/pnl has a tighter free-tier cap of 1 call/IP/day (heavy upstream).

What you need

• A wallet with at least $0.30 USDC on Base (the seed cost for trying every tool once is ~$0.62)
• The wallet's private key OR 12-word BIP-39 mnemonic
• Node 20+ installed

Install + configure

Step 1 — Generate or use an existing wallet

For testing, use a fresh wallet, not your main one. A simple way:

node -e "const {generatePrivateKey, privateKeyToAccount} = require('viem/accounts'); const pk = generatePrivateKey(); console.log('Address:', privateKeyToAccount(pk).address); console.log('Private key:', pk);"

Send ~$1 of USDC on Base to the printed address.

Step 2 — Claude Desktop

Edit your Claude Desktop config (location: macOS ~/Library/Application Support/Claude/claude_desktop_config.json, Windows %APPDATA%\Claude\claude_desktop_config.json):

{

"mcpServers": { "hyperd": { "command": "npx", "args": ["-y", "hyperd-mcp"], "env": { "HYPERD_WALLET_PRIVATE_KEY": "0xYOUR_PRIVATE_KEY_HERE" } } } }

Restart Claude Desktop. The hyperD tools appear in the conversation tool list.

Step 3 — Try it

Ask Claude in any conversation:

"What's the security score for USDC on Base? Use the hyperd.token.security tool."

Claude calls our endpoint, pays $0.05 from your wallet, returns the result. The whole flow takes ~2 seconds.

Cursor / Cline / Zed

Each MCP-compatible client has a similar config file. Same pattern: name the server hyperd, command is npx -y hyperd-mcp, set HYPERD_WALLET_PRIVATE_KEY env var.

For the full MCP client list and per-client config docs see https://modelcontextprotocol.io/clients.

Local-development install (without npm publish)

If you want to run from source instead of npx:

git clone https://github.com/hyperd-ai/hyperd-mcp.git

cd hyperd-mcp npm install npm run build

Then in your Claude Desktop config, point at the local build:

{

"mcpServers": { "hyperd": { "command": "node", "args": ["/full/path/to/hyperd-mcp/dist/server.js"], "env": { "HYPERD_WALLET_PRIVATE_KEY": "0xYOUR_PRIVATE_KEY_HERE" } } } }

Available tools

Synthesis tier — composed verdicts (Haiku 4.5, v1.1.0)

Each synthesis tool fans out multiple sub-calls internally and returns a single verdict + inputs + methodology.version + coverage envelope, authored by Claude Haiku 4.5.

Security

• Use a hot wallet, not your primary. The MCP server has the private key in process memory while it runs.
• Cap your spend by transferring only what you want to use. There's no built-in spending limit; the wallet's balance IS the limit.
• Don't commit your private key. The Claude Desktop config file is local; don't share it.

Configuration via mnemonic instead of private key

If you have a 12 or 24-word BIP-39 mnemonic instead of a raw key:

"env": {

"HYPERD_WALLET_MNEMONIC": "word1 word2 ... word12" }

Derives at the standard Ethereum path m/44'/60'/0'/0/0.

Optional env vars

• HYPERD_API_BASE — default https://api.hyperd.ai. Override for testnet or self-hosted.
• HYPERD_BASE_RPC — default public Base RPC. Override for higher rate limits.

Remote MCP-over-HTTPS (no install)

If you don't want to run the stdio server locally, hyperD's full tool catalog is also available as a remote MCP server:

POST https://api.hyperd.ai/mcp

Content-Type: application/json

{"jsonrpc":"2.0","id":1,"method":"tools/list"}

Same 24 paid tools, same free-tier quota (5 calls/IP/day, 10 lifetime), same X-Payment auth model for paid calls after quota. No npm install, no per-IDE config — just a URL.

Useful when:

• You're deploying an agent to a serverless platform (Vercel, Lambda) and don't want to bundle the stdio process
• You're using an MCP-aware service that expects a remote URL (Smithery enterprise, hosted gateways)
• You want to test the API surface from the command line with curl before committing to a local install
