Crypto Signals by ForgeMesh

Dedicated MCP wrapper for ForgeMesh Crypto Signals, an x402 crypto market-intelligence service.

This is separate from coinopai-mcp. Every tool targets crypto.forgemesh.io and pays the ForgeMesh Crypto Signals service wallet through x402 on Base.

Install

npx -y @forgemeshlabs/crypto-signals-mcp

Configure WALLET_PRIVATE_KEY with a dedicated low-balance Base wallet funded only with the USDC you intend the agent to spend. Never use a primary wallet.

Example MCP configuration:

{
  "mcpServers": {
    "crypto-signals-mcp": {
      "command": "npx",
      "args": ["-y", "@forgemeshlabs/crypto-signals-mcp"],
      "env": {
        "WALLET_PRIVATE_KEY": "${WALLET_PRIVATE_KEY}"
      }
    }
  }
}

Requirements

• Node.js 20 or newer and a dedicated, low-balance Base wallet (WALLET_PRIVATE_KEY).
• Spending caps: the server only talks to https://crypto.forgemesh.io and refuses to sign for any other payee, any network except Base mainnet, any asset except USDC, or any amount above the built-in $0.15 per-call and $10 per-session caps. The environment variables X402_MAX_PRICE_USD and X402_SESSION_BUDGET_USD can only lower those caps, never raise them.

Notes on live behavior: signal, preflight and decision tools cover every tracked symbol (crypto pairs plus US stocks and ETFs); forecasts cover BTC, ETH, SOL, XRP and ADA only. confidence in a decision journal is the measured directional hit rate for that symbol, or null when there are too few evaluated outcomes. audit_crypto_decision returns HTTP 425 with available_at while the window is still open, and decisions stay auditable for 7 days. History hours is an integer from 1 to 168. Stale data is refused, and refusals (unknown symbol 404, stale 503, window open 425) are not charged: errors from this server carry the HTTP status, charged flag and the service's own upstream body.

All outputs are market intelligence for research and decision support, not financial advice or market activity instructions.
