coinopai-mcp

Paid decision infrastructure for autonomous agents.

An MCP server that charges AI agents per verified intelligence request — using x402 micropayments on Base. Every decision gets a decision_id. Every decision_id can be audited against real prices.

This repo is the MCP client layer; paid intelligence is served from hosted CoinOpAI x402 endpoints.

Wrong predictions are shown too. That's the point.

The agent calls a tool → the MCP server receives an HTTP 402 → automatically signs a USDC micropayment → retries with the payment header → data returned. Configure once, pay automatically from the configured low-balance wallet.

The Verified Loop ($0.27/cycle)

check_trade_preflight  ──→  get_crypto_decision  ──→  [wait 1h]  ──→  audit_trade_decision
       $0.05                      $0.15                                      $0.07

   Is now allowed?           CONSIDER_LONG/SHORT              GOOD_DECISION
   Cooldown check?           NO_ACTION                        BAD_DIRECTION
   Regime ok?                + decision_id                    NOISE
   Signal strength?          + next_step hint                 + pnl_pct

Every decision is self-verifying. The decision_id links the prediction to the outcome. The audit fetches real market prices and produces a verdict. Nothing is hidden.

Real Output

Step 1 — Preflight (BTC, $0.05)

{
  "allowed": true,
  "symbol": "BTC/USD",
  "market_state": "NORMAL",
  "signal_strength": 0.72,
  "regime": "TREND",
  "cooldown_remaining_seconds": 0
}

Step 2 — Decision (BTC, $0.15)

{
  "symbol": "BTC/USD",
  "suggested_action": "CONSIDER_LONG",
  "confidence": 0.72,
  "regime": "TREND",
  "decision_id": "a3f8c1d2-9472-4dfe-b459-5df17b282614",
  "next_step": "Call audit_trade_decision with this decision_id after 1h using window=1h"
}

Step 3 — Audit (1h later, $0.07)

{
  "decision_id": "a3f8c1d2-9472-4dfe-b459-5df17b282614",
  "direction_held": true,
  "pnl_pct": 0.82,
  "verdict": "GOOD_DECISION"
}

Live results from real runs:

It gets some right. It gets some wrong. The loop makes both visible.

Install

Claude Code

Add to ~/.claude/settings.json:

{
  "mcpServers": {
    "coinopai": {
      "command": "npx",
      "args": ["-y", "coinopai-mcp"],
      "env": {
        "WALLET_PRIVATE_KEY": "0x<your-base-wallet-private-key>"
      }
    }
  }
}

Restart Claude Code. The 9 tools appear automatically.

Claude Desktop

Add to your Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "coinopai": {
      "command": "npx",
      "args": ["-y", "coinopai-mcp"],
      "env": {
        "WALLET_PRIVATE_KEY": "0x<your-base-wallet-private-key>"
      }
    }
  }
}

Smithery

Install via Smithery. Configure a dedicated low-balance payment wallet. Do not use your primary wallet.

Get a Wallet

1. Install Coinbase Wallet or any EVM wallet
2. Switch to Base network
3. Buy or bridge USDC ($1 = ~3 full verified cycles)
4. Use a dedicated low-balance Base wallet for agent payments and provide its private key locally via environment variable.

Your wallet key stays local. It never leaves your machine. Each payment is a signed micropayment — not a blanket approval.

Agent Code Example

// Step 1 — gate check ($0.05)
const pre = await mcp.call("check_trade_preflight", { symbol: "BTC" })
if (!pre.allowed) return  // cooldown, bad regime, or stale data

// Step 2 — get decision ($0.15)
const dec = await mcp.call("get_crypto_decision", { symbol: "BTC" })
if (dec.suggested_action === "NO_ACTION") return

// Store the decision_id — you'll need it to close the loop
const { decision_id, suggested_action, confidence } = dec

// Step 3 — act on the decision here...

// Step 4 — audit 1 hour later ($0.07)
const audit = await mcp.call("audit_trade_decision", {
  decision_id,
  window: "1h"
})
// verdict: "GOOD_DECISION" | "BAD_DIRECTION" | "NOISE"
console.log(audit.verdict, audit.pnl_pct + "%")

Every decision response includes a next_step field — your agent always knows when and how to audit.

Symbol unavailable? If a symbol isn't in the current Kronos cycle:

{
  "status": "UNAVAILABLE_THIS_CYCLE",
  "available_symbols": ["BTC/USD", "ETH/USD", "XRP/USD"],
  "retry_hint_seconds": 900
}

Route to an available symbol or wait 15 minutes for the next cycle.
