M2M Sentinel tools (6)

write = sends, deletes, buys or posts
  • m2m_audit_contractFree

    Inspect static bytecode capabilities (e.g. mint, pause, freeze, upgradeability slots), common proxy target resolution, and coverage index for a single Base contract address. Factual capability observation only, not a safety or exploitability guarantee. Distinguishable from m2m_get_service_status (infrastructure status) and legacy score-only endpoints.

  • m2m_get_dex_liquidityFree

    Fetch aggregate pool reserve, depth, and volume metrics across tracked Base DEX liquidity pools. Reports tracked-pool metrics only and does not filter by individual trading pair; contrast with m2m_get_token_price, which observes token spot prices.

  • m2m_get_gas_metricsFree

    Fetch current Base gas price in wei/gwei with RPC provenance for the upstream observation. Read-only telemetry; does not inspect contract code, return token/DEX pricing, or authorize or submit transactions.

  • m2m_get_service_statusFree

    Fetch operational status, upstream Base RPC quorum status, and persistence availability for M2M Sentinel infrastructure. Does not return blockchain or market telemetry.

  • m2m_get_token_priceFree

    Fetch the median Base DEX spot price in USD across up to five deepest indexed pools, with contract address, decimals, and pool provenance for one allowlisted token symbol (e.g. USDC, WETH, AERO). Does not return historical price series; contrast with m2m_get_dex_liquidity, which returns aggregate pool reserve depth rather than an asset price.

  • m2m_get_whale_signalsFree

    Fetch up to 50 tracked recent high-value ERC-20 transfer signals on Base with transaction hashes, token/sender/receiver addresses, amounts, and valuation provenance. Observes large on-chain transfer events without query parameter limits; does not inspect contract bytecode or query DEX pricing.

M2M Sentinel SDK & MCP Server

Official multi-language client library, Model Context Protocol (MCP) server, and Coinbase AgentKit ActionProvider for M2M Sentinel — deterministic EVM bytecode capability observations and common-proxy resolution for autonomous applications operating on Base. Callers own transaction policy.

⚡ 1. Model Context Protocol (MCP) Server

Connect M2M Sentinel directly to Claude Desktop, Cursor, Windsurf, or any MCP-compliant LLM agent.

Option A: 1-Click via Smithery

npx -y @smithery/cli mcp add M2M-Sentinel/m2m-sentinel-sdk --client claude

Option B: Local Stdio (claudedesktopconfig.json)

{
  "mcpServers": {
    "m2m-sentinel": {
      "command": "npx",
      "args": ["-y", "m2m-sentinel-sdk"],
      "env": {
        "M2M_SENTINEL_API_KEY": ""
      }
    }
  }
}

Option C: Remote Streamable HTTP

  • Current MCP endpoint: https://api.m2msentinel.com/mcp
  • Legacy HTTP+SSE compatibility: https://api.m2msentinel.com/sse with messages at https://api.m2msentinel.com/messages

🤖 2. Coinbase AgentKit Integration

import { AgentKit } from "@coinbase/agentkit";
import { m2mSentinelActionProvider } from "m2m-sentinel-sdk";

const agentKit = await AgentKit.from({
  walletProvider,
  actionProviders: [
    m2mSentinelActionProvider({
      apiKey: process.env.M2M_SENTINEL_API_KEY
    })
  ]
});

📦 3. JavaScript / TypeScript Client

npm install m2m-sentinel-sdk
const { M2MSentinelClient } = require('m2m-sentinel-sdk');

const client = new M2MSentinelClient();

async function main() {
  const audit = await client.auditContract('0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913');
  console.log('Proxy Detected:', audit.audit.proxyResolution.isProxy);
  console.log('Proxy Target:', audit.audit.proxyResolution.targetAddress);
  console.log('Capabilities:', audit.audit.verdict.executableCapabilities);
  console.log('Evidence:', audit.audit.dissection.capabilities);
}

main().catch(console.error);

🛡️ Base Account wallet_sendCalls Guard

The public SDK includes guardWalletSendCalls, a customer-side execution-identity boundary for Base Account / EIP-5792 batches. It preflights the anchor call and evaluates its caller policy before scheduling any remaining call, then pins remaining calls to the first trusted block identity in waves of at most four. Each settled wave is validated and policy-checked in ascending request-index order before a later wave starts; a failure or rejection stops later scheduling. The original detached request is forwarded only after all checks pass. It does not sign, broadcast, custody funds, infer inner UserOperation semantics, or make a safety claim. See examples/baseaccountpaymaster_guard.js for a no-network fixture.

🐍 4. Python Client

pip install m2m-sentinel
from m2m_sentinel import M2MSentinelClient

client = M2MSentinelClient()
audit = client.audit_contract("0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913")
print("Proxy detected:", audit["audit"]["proxyResolution"]["isProxy"])
print("Proxy target:", audit["audit"]["proxyResolution"].get("targetAddress"))
print("Capabilities:", audit["audit"]["verdict"]["executableCapabilities"])
print("Evidence:", audit["audit"]["dissection"]["capabilities"])

Does M2M Sentinel need an API key?
Yes. The registry entry asks for M2M_SENTINEL_API_KEY, x-api-key, PAYMENT-SIGNATURE.
Is M2M Sentinel maintained?
The last commit was 30 days ago (2026-10-06). The latest release is v1.2.5.
Is M2M Sentinel up?
100% of our last 28 checks got an answer. We check remote servers about four times a day.
How does M2M Sentinel compare with other MCP servers?
safety score 90/100 (higher than 83% of 48,243 servers); tools 6 (the typical server has 7); tools that change things 0% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
