What your AI can do with X402 Tools
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “llm_completion”: LLM inference at a flat $0.001 per call - no token metering, no surge. POST a prompt, get the completion. Same price for 10 tokens or 4000,.”
“Use “evm_balance”: Native coin balance (ETH, MATIC...) for any address, on Base, Ethereum, Polygon, Arbitrum or Optimism. Flat price, no rate limits, no API ke.”
“Use “evm_erc20_balance”: ERC20 token balance for any wallet - USDC, USDT, DAI or any token - via balanceOf. Returns the raw amount and the decimals so you can format.”
“Use “evm_token_info”: Name, symbol, decimals and total supply of any ERC20 contract in one call. Useful to label a token address before showing it to a user. Flat.”
How secure is the X402 Tools MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how X402 Tools holds up.
Official endpoint
Operated by X402 Tools (workers.dev) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If X402 Tools adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

The X402 Tools MCP server at a glance
https://flat-rate-llm.kikoribera03.workers.dev/mcpQuestions, answered
Is there an official X402 Tools MCP server?
Yes — X402 Tools operates its own remote MCP server at flat-rate-llm.kikoribera03.workers.dev. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect X402 Tools to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick X402 Tools in the directory. No account or sign-in is needed. From then on, X402 Tools's tools are available in every client you've connected to gate.
Do I need to host anything?
No. X402 Tools runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the X402 Tools MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
