MCP (no wallet):

claude mcp add --transport http agentforge https://agentforge-taupe.vercel.app/mcp

Cursor, Windsurf, Claude Desktop, ElizaOS: add an HTTP MCP server with the same URL.

From code, paying per call:

npm install agentforge-tools

import { AgentForge } from 'agentforge-tools';

const af = new AgentForge({ privateKey: process.env.AGENT_KEY as `0x${string}`, maxPaymentUsd: 0.1 });
const sim = await af.simulateTransaction({ chain: 'base', from: '0xYourWallet', transactions: [{ to, data }] });
if (sim.verdict === 'avoid') throw new Error('refusing to sign');

Any x402 client: send the request unpaid, get a 402 with the exact price, pay, retry. Failed calls (4xx/5xx) are never charged.

Coinbase AgentKit: an agentforge action provider is proposed upstream in coinbase/agentkit#1619.

Deterministic, no LLM.
POST /v1/risk-batch	$0.004 per token, 2-25 tokens per call	Rug-check 2-25 EVM tokens in one call: holder, permission, and liquidity risk scores per token.
POST /v1/solana/tx-explain	$0.05	Decode a Solana transaction into plain English: labeled programs, token/SOL movements, and risk flags. Falls back to raw RPC decoding if enhanced parsing is unavailable.

Roadmap

The 90-day plan is docs/growth-plan.md; the executor log is docs/growth-log.md.

Development

npm install
npm run dev        # http://localhost:3402
npm test

Payments: x402 v2, USDC on Base (and Solana for the Solana endpoints), settled through the CDP facilitator. Every paid route returns 402 to an unpaid request; GET /health/paid checks all of them.
