Model Context Protocol (MCP) server for freee API integration
Nothing to run from here
Base Web3 M2m Hub is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http base-web3-m2m-hub-mcp https://auditor-x402.onrender.com/mcp/v1
# 2 — ask your agent for something these tools do

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http base-web3-m2m-hub-mcp https://auditor-x402.onrender.com/mcp/v1Reconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.

17 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
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).
No parameter schema on file.
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).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| pair | string | no | Only "WETH/USDC" is supported |
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).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| minUsdcAmount | number | no | Minimum transfer size in USDC (min 1000, default 100000) |
| windowBlocks | number | no | Blocks to scan, 25-600 (default 300, ~2s per block) |
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).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| asset | string | no | ERC-20 address (0x...) of the asset; default WETH |
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).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tokenAddress | string | yes | ERC-20 token contract address (0x...) on Base |
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).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| userAddress | string | yes | Wallet address (0x...) to inspect |
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).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| windowBlocks | number | no | Blocks to scan, 50-3000 (default 1500) |
| limit | number | no | Max pools returned, 1-30 (default 15) |
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 p
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tokenAddress | string | yes | ERC-20 token contract address (0x...) on Base |
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).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| address | string | yes | Address (0x...) to inspect |
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).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tokenAddress | string | yes | ERC-20 token contract address (0x...) on Base |
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).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| userAddress | string | yes | Wallet address (0x...) to inspect |
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
No parameter schema on file.
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).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| asset | string | no | ERC-20 address (0x...); default WETH |
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).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tokenAddresses | array | yes | Array of ERC-20 addresses (0x...), max 15 |
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).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tradeSizeUsd | number | no | Trade size in USD, 100-5,000,000 (default 10000) |
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
| Parameter | Type | Required | Notes |
|---|---|---|---|
| address | string | yes | Contract address (0x...) on Base |
| data | string | yes | Hex calldata starting with a 4-byte function selector (e.g. "0x18160ddd") |
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).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| address | string | yes | Contract address (0x...) to read logs from |
| topic0 | string | no | Optional 32-byte event signature hash (0x...) to filter by |
| windowBlocks | number | no | Blocks to scan (10-120, default 100) |

ATool-list grade · score 96 / 100
Release 46.0.0 · scanned 28 Oct 2026
Graded from the tools this server lists, not from its source code.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.
