MACH Base — questions

Answers built from our own checks of this server.

What can MACH Base do?

It exposes 17 tools, read directly from the server on our last check. Among them: base_allowance, base_block, base_block_number, base_contract_code, base_contract_info, base_erc20_balance and 11 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is MACH Base working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 6 of 6 checks got a reply (100.0%), average response time 208 ms. The bar chart above shows every period we have measured.

How do I connect MACH Base?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does MACH Base need an API key?

No. MACH Base completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 17 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is MACH Base?

It answers our handshake in 208 ms on average, which is faster than 69% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
