What your AI can do with MACH Base
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “mach_choose”: Free decision layer: map an agent goal to the narrowest paid MACH Base capability, exact price, expected result fields and exact next reques.”
“Use “base_block_number”: Check Base chain progress: return the latest mainnet block number for freshness checks and polling. This is not transaction confirmation. Co.”
“Use “base_gas_price”: Check the current Base gas price in wei before estimating transaction fees. The quote alone is not the total transaction cost. Costs $0.005.”
“Use “base_wallet_balance”: Check whether a Base wallet has native ETH available for gas: return its balance in wei. Read-only; no wallet access or signing. Costs $0.00.”
How secure is the MACH Base MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how MACH Base holds up.
Official endpoint
Operated by MACH Base (mach.gallery) 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 MACH Base adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.

https://api.mach.gallery/mcpQuestions, answered
Is there an official MACH Base MCP server?
Yes — MACH Base operates its own remote MCP server at api.mach.gallery. 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 MACH Base to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick MACH Base in the directory. No account or sign-in is needed. From then on, MACH Base's tools are available in every client you've connected to gate.
Do I need to host anything?
No. MACH Base runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the MACH Base 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?
Yes — you can get started with gate for free and connect MACH Base in minutes. No credit card required.
