Overview

AI-generated overview

Local MCP server for Gate402's pay-per-call x402 APIs: LLM inference, web scraping, Base on-chain and DEX data, SEC filings, plus free local utilities.

What you can do
  • Run open-model LLM inference and metered GPU/CPU container jobs, with signed usage receipts
  • Fetch public URLs as clean Markdown, including a stealth mode with residential proxies and CAPTCHA solving
  • Look up Base on-chain wallet and token data, DEX prices and liquidity, token risk and momentum signals, best swap routing, and new token launches
  • Retrieve recent news sentiment and latest SEC EDGAR filings for a ticker
  • Compress text, run semantic dedup lookups, and browse or join the GPU marketplace as a provider
  • Use free local tools: token counting, HTML-to-Markdown conversion, and JSON repair
When to use it
Useful when an agent needs metered, pay-per-call access to LLM inference, web scraping, or Base crypto and SEC filing data without creating an account, and when you want a few offline text utilities bundled in the same server.
Requirements
Runs locally over stdio via npm (npx gate402-mcp) or a global install; Node.js required. No signup: a free-credit key is self-claimed on first use and cached in ~/.gate402-mcp. Optional GATE402_API_KEY for a funded account, GATE402_BASE_URL to override the gateway, and GATE402_CONFIG_DIR to change the cache location. Network access needed for paid tools.
Before you install
Most tools spend money per call from a prepaid credit balance, and the marketplace inference tool settles on-chain per call. The server writes a key file to ~/.gate402-mcp on first run. Scraping and stealth tools send target URLs to third-party gateways and proxies. Compute tool currently returns 503. Becoming a provider involves on-chain USDC payouts.

Installation

In SourceWeft

  1. Open Gate402 Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

[x402 trust]

MCP server for Gate402 — pay-per-call agent APIs over HTTP 402 (x402 / USDC on Base). Gives any MCP client a full toolkit with no signup and a free tier on first runs — GPU/CPU compute, open-model LLM inference, a GPU marketplace, a complete Base trading loop (discover → vet → read → execute), and web tools:

ToolWhat it doesPrice
gate402_inferOpen-model LLM inference (Llama 3.1 8B/70B, Qwen 2.5, Mistral); billed on actual tokens, signed usage receiptper-token (from $0.05/1M in)
gate402_computeMetered GPU/CPU for a container job, with a signed execution receipt. Not available yet: answers 503 until a compute provider is connectedper-second
gate402_scrapeFetch any public URL, render JS, strip nav/ads → clean LLM-ready Markdown$0.002
gate402_scrape_stealthCloudflare/anti-bot fetch via residential proxies + CAPTCHA solving → clean Markdown$0.05
gate402_minifyCompress text to cut downstream LLM token spend (~40%)$0.005 / 10k tok
gate402_dedupSemantic vector-cache lookup (exact + cosine)$0.001 hit / $0.003 miss
gate402_onchainOn-chain wallet/token intel on Base (balances, EOA/contract, tx count, token metadata)$0.01
gate402_dexLive DEX price / liquidity / 24h volume for a Base token$0.01
gate402_newsRecent news headlines + bull/bear sentiment for a ticker/topic$0.02

gate402_token_riskRug/tradeability verdict for a Base token (score + SAFE/CAUTION/AVOID; liquidity, honeypot sim, holder concentration)$0.03
gate402_momentumMomentum + order-flow signal for a Base token (RISING/FALLING + ACCUMULATION/DISTRIBUTION, honeypot-gated)$0.02
gate402_best_swapBest-execution intel: which DEX pool + estimated price impact for a trade size$0.02
gate402_launchesRadar of the freshest Base token launches, lightly pre-screened$0.02

…plus three free tools that run locally in this process (pure compute — no payment, no key, no network):

ToolWhat it does
gate402_token_countEstimate the token count of a string (budget your context window)
gate402_html_to_mdConvert an HTML string you already have into clean Markdown
gate402_json_repairCoerce malformed / LLM-mangled JSON into valid JSON

GPU marketplace

Gate402 also routes to third-party GPU/compute providers with escrow-on-success — the buyer is charged only if the provider delivers. Providers keep 85% of each call, paid out on-chain in USDC on Base.

ToolWhat it does
gate402_market_inferLLM inference via the marketplace, routed to the cheapest healthy provider. x402-native (settles on-chain per call — needs an x402 client, not the free-tier key)
gate402_providersFree. Browse active providers — model, per-call price, reliability
gate402_become_providerFree. List your own GPU and earn 85%/call — returns the exact sign-message + registration request

How billing works

On first use the server self-claims a free-credit API key from Gate402 and caches it at ~/.gate402-mcp/key.json. Calls draw down that credit. When it runs out, tools return a top-up link instead of failing. To skip the free tier, set GATE402_API_KEY to a funded account (top up).

The payment is the auth — there are no accounts to create.

Install

bash
npm install -g gate402-mcp

Or run without installing via npx gate402-mcp.

Configure your MCP client

Claude Desktop / Claude Code

Add to your MCP config (claude_desktop_config.json, or claude mcp add):

json
{  "mcpServers": {    "gate402": {      "command": "npx",      "args": ["-y", "gate402-mcp"]    }  }}

Cursor / Cline / Windsurf

Same shape — point the MCP server command at npx -y gate402-mcp.

Agent frameworks (LangChain, CrewAI, LlamaIndex)

gate402 is a standard stdio MCP server, so any framework with an MCP adapter can load all 17 tools:

LangChain / LangGraph (langchain-mcp-adapters):

python
from langchain_mcp_adapters.client import MultiServerMCPClientclient = MultiServerMCPClient({"gate402": {"command": "npx", "args": ["-y", "gate402-mcp"], "transport": "stdio"}})tools = await client.get_tools()   # feed into your agent

CrewAI (MCPServerAdapter):

python
from crewai_tools import MCPServerAdapterfrom mcp import StdioServerParametersparams = StdioServerParameters(command="npx", args=["-y", "gate402-mcp"])with MCPServerAdapter(params) as tools:    ...  # pass tools to your Crew

LlamaIndex (McpToolSpec):

python
from llama_index.tools.mcp import BasicMCPClient, McpToolSpectools = McpToolSpec(client=BasicMCPClient("npx", args=["-y", "gate402-mcp"])).to_tool_list()

Once wired, the agent calls the tools autonomously; the free-credit key is claimed on first use, and paid tools draw down from it.
