Nothing serious here today

Today is the operative word: we check MACH Base every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 18

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

base

base_allowance

Check a Base token approval before an agent acts: return the ERC-20 allowance for one token, owner and spender. Does not grant approval. Costs $0.005 USDC via x402.

base_block

Inspect a Base block by number or tag: retrieve its header and transaction hashes to investigate chain activity. Costs $0.005 USDC via x402.

base_block_number

Check Base chain progress: return the latest mainnet block number for freshness checks and polling. This is not transaction confirmation. Costs $0.005 USDC via x402.

base_contract_code

Tell a Base contract address from an externally owned account: return whether code is deployed and its bytecode size. Not a security audit. Costs $0.005 USDC via x402.

base_contract_info

Identify a Base contract before interacting: inspect bytecode size, available token metadata and common interface signals. Not a security audit. Costs $0.005 USDC via x402.

base_erc20_balance

Check a wallet’s USDC or ERC-20 balance on Base: return raw token units for a specified token contract and wallet address. Costs $0.005 USDC via x402.

base_erc20_transfers

Find recent ERC-20 Transfer events on Base, optionally filtered by sender or recipient wallet. Results cover only the queried block window. Costs $0.005 USDC via x402.

base_eth_call

Read Base contract state without broadcasting a transaction: run eth_call with supplied calldata and return the raw response. Costs $0.005 USDC via x402.

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 USDC via x402.

base_logs

Find Base smart-contract events in a bounded block range: return onchain logs filtered by contract address and optional topics. Costs $0.005 USDC via x402.

base_nonce

Prepare a Base transaction: get a wallet’s current nonce without signing or broadcasting a transaction. Costs $0.005 USDC via x402.

base_receipt

Check whether a Base transaction was mined and succeeded: return receipt status and confirmations. This does not prove the correct payee, token amount or service delivery. Costs $0.005 USDC via x402.

base_total_supply

Check a Base ERC-20 or ERC-721 contract’s reported total supply. Contract data is not independently audited circulation. Costs $0.005 USDC via x402.

base_transaction

Inspect a Base transaction by hash: retrieve sender, recipient, value, calldata and transaction fields. Use Transaction Context for receipt and confirmation status. Costs $0.008 USDC via x402.

base_transaction_context

Investigate a Base payment timeout or failed transaction with transaction, receipt, gas and fee context. Onchain success is not proof that a specific USDC obligation or service delivery was met. Costs $0.008 USDC via x402.

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 $0.005 USDC via x402.

base_wallet_snapshot

Check a Base wallet’s funding context in one read: return native ETH and balances for up to ten specified ERC-20 contracts. No signing or custody. Costs $0.005 USDC via x402.

mach

mach_choose

Free decision layer: map an agent goal to the narrowest paid MACH Base capability, exact price, expected result fields and exact next request. Returns no live chain data and has no side effects.

MACH Base — questions

Answers built from our own checks of this server.

What can MACH Base do?

It exposes 18 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 12 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 91 of 91 checks got a reply (100.0%), average response time 156 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 in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own credentials: it refuses anonymous clients.

Does MACH Base need an API key?

Yes. Every time we knock, MACH Base answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.

How fast is MACH Base?

It answers our handshake in 156 ms on average, which is faster than 81% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
