Common questions

Is Agent Tollgate safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.4.1) reached the registry 8 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Starreel

Live at https://skinwinking.com. Machine-readable: /llms.txt, /openapi.json, MCP at https://skinwinking.com/mcp.

Pay-per-call trading intelligence and fee-bearing swap routing for autonomous agents, on Cloudflare Workers.

Revenue paths:

  1. x402 micropayments in USDC (Polygon or Solana) for orderbook-imbalance (0.02 USDC) and token-audit (0.20 USDC).
  2. 30 bps platform fee on swaps built by quote-and-build (Jupiter on Solana, LI.FI cross-chain/EVM).

All payments go straight to the merchant addresses in wrangler.toml. The server holds no keys and no funds.

Layout

PackageRole
packages/coreconfig, route catalog, on-chain payment verification (EVM, Solana, x402 facilitator), replay protection interface
packages/api-workerHono Worker, x402PaymentGate middleware, Durable Object nonce store, route handlers
packages/omni-routerJupiter (Solana) and LI.FI (cross-chain) quote builders with fee embedding
packages/discovery/llms.txt, /openapi.json, MCP server (HTTP at /mcp, stdio via npm run mcp)
packages/simulation-agentend-to-end simulated agent

Local run

npm install

cp .env.example .dev.vars # then set SOLANA_RPC_URL and EVM_RPC_URL to private endpoints npm run dev # http://127.0.0.1:8787, simulation receipts enabled

npm run dev sets SIM_SECRET, which enables HMAC simulation receipts (Bearer sim_...). Never set SIM_SECRET in production.

If port 8787 is busy: npx wrangler dev --port 8799 --var SIM_SECRET:dev-simulation-secret and BASE_URL=http://127.0.0.1:8799.

Simulation

With npm run dev running in another terminal:

npm run simulate

Steps: unpaid call returns 402, simulated payment succeeds, replay is rejected, a Solana swap quote proves the fee account is inside the built transaction, a Polygon to Base quote proves the LI.FI integrator fee.

Production prerequisites

  1. RPC: public endpoints are rate-limited or blocked. Use private ones.
   npx wrangler secret put SOLANA_RPC_URL

npx wrangler secret put EVM_RPC_URL

2. **LI.FI integrator**: register `LIFI_INTEGRATOR` at https://portal.li.fi, set the fee wallet to the EVM payout address, and set the fee to 0.3%. Without it LI.FI rejects quotes that carry `fee`.
  1. Solana fee token accounts: the Jupiter fee is paid in the output token to the merchant's associated token account for that mint. The route returns FEE_ACCOUNT_MISSING until that account exists. Receiving a small amount of the token (or creating the ATA in Phantom) creates it. USDC and wSOL cover the main pairs.
  2. Optional X402_FACILITATOR_URL enables X-402-Signature settlement through an x402 facilitator.

Deploy

npx wrangler deploy

Attach the domain under Workers & Routes in the Cloudflare dashboard (custom domain on the worker).

Payment proofs

HeaderMeaning
Authorization: Bearer 0x<64 hex>Polygon USDC transfer to the merchant, at least the route price, at least EVM_MIN_CONFIRMATIONS deep, younger than PAYMENT_MAX_AGE_SEC
Authorization: Bearer Solana USDC transfer, confirmed commitment
X-402-Signature: x402 payload verified and settled via the facilitator

Each proof is accepted once (Durable Object, 7 day TTL).
