This one has been quiet for a while

Quiet is not dead — but it is worth knowing when it wakes up, or when someone else takes it over. We watch the repository and tell you either way.

Available tools 17

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

contract

contract-logs

Recent event logs for any contract on Base over a bounded recent window (reads eth_getLogs). Optionally filter by topic0 (event signature hash). Returns up to 50 logs with block, tx hash, topics and data. Window is limited by the RPC log-range quota. Use this for generic event queries not covered by whale-wallet-tracker or token-deploy-radar. Price: 0.0050 USDC per call (premium: always paid).

contract-profile

Contract structure ONLY: bytecode size, proxy detection (EIP-1167 / EIP-1967 implementation and admin) and owner() for any address on Base. NOT a security audit. For a full token check that also adds risk flags and pool liquidity, use token-due-diligence; to read an arbitrary view function use contract-read. Price: 0.0050 USDC per call (premium: always paid).

contract-read

Generic read-only call to any contract on Base: provide an address and hex calldata (4-byte selector, e.g. 0x18160ddd = totalSupply, optionally followed by ABI-encoded args) and get the raw return data plus best-effort uint/address/bool/string decoding. Read-only (never sends a transaction). Use this for arbitrary view functions not covered by a dedicated tool. Price: 0.0030 USDC per call (premium: always paid).

token

token-deploy-radar

Newest Uniswap v3 pools created on Base (PoolCreated events) with token symbols, fee tier and block. A new pool does not imply a legitimate token. Price: 0.0050 USDC per call (premium: always paid).

token-due-diligence

FULL token check (BUNDLE): combines GoPlus risk flags (= liquidity-health) + contract/proxy/owner facts (= contract-profile) + Uniswap v3 pools vs WETH/USDC with quote-side liquidity in USD, in a single call. Objective signals, not a verdict. Use this instead of calling liquidity-health and contract-profile separately; use the individual tools only if you need just one aspect. Price: 0.0300 USDC per call (premium: always paid).

token-spot-price

Price of ONE token: on-chain USD spot price for a single ERC-20 on Base, from the deepest Uniswap v3 pool vs USDC/WETH (slot0), with the pool/fee tier used and its USD depth. No off-chain feed; thin pools are easy to manipulate. To price MANY tokens at once, use multi-token-price instead (one cheaper call). Price: 0.0020 USDC per call (first call free).

aave

aave-yield

Live Aave v3 reserve rates on Base read on-chain: current supply APY and variable borrow APY for any listed asset (default WETH). For yield and borrow-cost bots. Price: 0.0040 USDC per call (premium: always paid).

dex

dex-arbitrage

DEX pricing/spread ONLY: WETH/USDC spot price on-chain from Uniswap v3 and Aerodrome v2, with gross spread in bps and which side is cheaper (fees, gas and slippage excluded). Use this for cross-DEX pricing; for expected slippage of a given trade size use pool-slippage; if you also need gas use market-snapshot. Price: 0.0050 USDC per call (premium: always paid).

flash

flash-loans

Aave v3 on Base: available flash-loan liquidity and flash-loan fee for any listed asset (default WETH), read on-chain. Price: 0.0050 USDC per call (premium: always paid).

gas

gas-optimizer

Gas ONLY: live Base Mainnet gas from eth_feeHistory — latest and 10-block average base fee (gwei), priority-fee percentiles (p25/p50/p75) and a congestion label. Use this when you need gas and nothing else; if you also want WETH/USDC pricing, use market-snapshot instead (one cheaper call). Price: 0.0020 USDC per call (first call free).

liquidation

liquidation-monitor

Aave v3 on Base: total collateral, debt, health factor and risk band (LIQUIDATABLE / AT_RISK / WATCH / HEALTHY / NO_DEBT) for any wallet. Price: 0.0050 USDC per call (premium: always paid).

liquidity

liquidity-health

Token risk flags ONLY: for an ERC-20 on Base (honeypot, tax over 10%, mintable, unverified source, hidden owner, pausable...) from GoPlus plus on-chain facts (symbol, supply, owner). No safety verdict; no flags is not a guarantee. For a full check that ALSO adds contract/proxy facts and pool liquidity in one call, use token-due-diligence instead. Price: 0.0100 USDC per call (premium: always paid).

market

market-snapshot

BUNDLE: one-call Base market snapshot combining live gas (base fee, priority-fee percentiles, congestion) AND WETH/USDC spot price + gross spread across Uniswap v3 / Aerodrome. Use this when you want both gas and DEX pricing in a single cheaper call; do NOT also call gas-optimizer or dex-arbitrage for the same purpose. Prefer the individual tools only if you need just one of the two. Price: 0.0060 USDC per call (premium: always paid).

multi

multi-token-price

Price of MANY tokens (BATCH): on-chain USD spot price for up to 15 ERC-20s in one call, each from its deepest Uniswap v3 pool vs USDC/WETH. Tokens with no pool return an error entry. Use this for 2+ tokens; for a single token use token-spot-price (cheaper). Price: 0.0080 USDC per call (premium: always paid).

pool

pool-slippage

Estimated price impact / slippage for a WETH/USDC trade of a given USD size on Uniswap v3, from on-chain pool depth. Order-of-magnitude signal (v3 is concentrated liquidity), useful for MEV/execution bots before trading. Price: 0.0050 USDC per call (premium: always paid).

wallet

wallet-portfolio

Portfolio of a wallet on Base: native ETH plus a curated set of major ERC-20s (USDC, WETH, cbETH, cbBTC, DAI, USDbC), each valued in USD on-chain via Uniswap v3. Returns per-token amounts, USD values and the total. Price: 0.0040 USDC per call (premium: always paid).

whale

whale-wallet-tracker

Large USDC transfers on Base over the most recent blocks (default ~300), from confirmed Transfer logs: amount, sender, receiver, tx hash, block. Price: 0.0100 USDC per call (premium: always paid).

Base Web3 M2m Hub — questions

Answers built from our own checks of this server.

What can Base Web3 M2m Hub do?

It exposes 17 tools, read directly from the server on our last check. Among them: aave-yield, contract-logs, contract-profile, contract-read, dex-arbitrage, flash-loans 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 →

What is Base Web3 M2m Hub mostly used for?

Its tools cluster around contract and token. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Base Web3 M2m Hub 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 194 ms. The bar chart above shows every period we have measured.

Is Base Web3 M2m Hub still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Base Web3 M2m Hub?

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.

Does Base Web3 M2m Hub need an API key?

No. Base Web3 M2m Hub 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 Base Web3 M2m Hub?

It answers our handshake in 194 ms on average, which is faster than 80% 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.
