Overview

AI-generated overview

Remote MCP endpoint offering 128 pay-per-call crypto, trading, web and utility tools, billed in USDC per request via x402.

What you can do
  • Plan and discover tools: free task planning and a catalog that ranks tools against a plain-language goal
  • Crypto market data: prices, candles, technical indicators, funding rates, fear and greed, stablecoin pegs, DEX pairs, trending and new tokens
  • On-chain checks: token rug-pull audits, address type checks, wallet balances, transaction status, gas prices, Solana network stats, DeFi TVL
  • Swap routing: quotes with an unsigned transaction and a risk check on the output token
  • Web and network lookups: page text extraction, DNS, HTTP status and security headers, WHOIS/RDAP, email and domain email-security checks
  • Developer utilities: hashing, base64, UUIDs, JWT decoding, JSON and CSV conversion…
When to use it
Useful when an assistant needs live crypto market or on-chain data, pre-trade token risk checks, or quick web and network lookups without wiring up separate APIs, and when paying a small per-call fee in USDC is acceptable.
Requirements
Remote streamable HTTP endpoint; no account or API key declared. Paid tools require an x402 USDC payment proof per call, sent as an Authorization bearer token (Polygon or Solana transfer) or an X-402-Signature header. A wallet able to sign USDC transfers is needed.
Before you install
Most tools cost USDC per call (0.001 to 0.20 USDC), and swaps built by the quote tool carry a 30 bps platform fee, so costs accumulate with use. Payment proofs are single-use and tied to merchant addresses. The JWT tool decodes tokens without verifying signatures. Web extraction and HTTP checks fetch arbitrary public URLs on your behalf.

Installation

In SourceWeft

  1. Open Agent Tollgate in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.skinwinking%2Fagent-tollgate/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

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

Local run

bash
npm installcp .env.example .dev.vars        # then set SOLANA_RPC_URL and EVM_RPC_URL to private endpointsnpm 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:

bash
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.
    bash
    npx wrangler secret put SOLANA_RPC_URLnpx 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.
  3. 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.
  4. Optional X402_FACILITATOR_URL enables X-402-Signature settlement through an x402 facilitator.

Deploy

bash
npx wrangler deploy

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

ParameterschainrequiredaddressrequiredpaymentProof

swap_quote_and_build

Same-chain Solana swaps route through Jupiter with a referral fee account. Cross-chain routes try LI.FI Intents (solver-based, competitive pricing) first, then fall back to classic LI.FI routing. Supports Solana, Ethereum, Base, Arbitrum, Polygon, Bitcoin and Tron. The response contains a serialized unsigned transaction to be signed and broadcast by the caller. A 30 bps platform fee is embedded in the route.
