Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “base_address”: Base (chain 8453) address snapshot: EOA vs contract vs EIP-7702, ETH balance, nonce, code size and native USDC balance, at the latest block.”
“Use “base_erc20_balance”: ERC-20 balance of any address for any token on Base, with symbol and decimals already applied (raw and human-readable). Costs $0.002 USDC on.”
“Use “base_token”: Token facts on Base: name, symbol, decimals, total supply, contract code size, owner() and EIP-1967 proxy implementation, plus plain-languag.”
“Use “base_tx”: Human-readable summary of a Base transaction: status, block time, from/to, value, total fee (incl. L1 fee), and decoded ERC-20 Transfer even.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how BaseLens holds up.
Operated by BaseLens (vercel.app) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If BaseLens adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose BaseLens in the gate directory. No sign-in needed.
BaseLens's tools are live in every AI client you've connected — with rules and logging built in.

https://baselens-api.vercel.app/mcpYes — BaseLens operates its own remote MCP server at baselens-api.vercel.app. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
Add gate's gateway URL to your AI client once, then pick BaseLens in the directory. No account or sign-in is needed. From then on, BaseLens's tools are available in every client you've connected to gate.
No. BaseLens runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
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.
Yes — you can get started with gate for free and connect BaseLens in minutes. No credit card required.
Every server below works through the same gateway URL — connect once, add tools anytime.
