Endpoint Security46
Transport & Reachability100
Schema Quality & AI Usability81
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 1451 tokens (~120/item across 12 items; 12 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Tool Safety75
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "base_simulate_transfer" implies "transfer" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
  • An AI judge read all 13 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

Install

How do I install the dev.workers.dolerite.base-onchain-tools/base-onchain-tools MCP server?

dev.workers.dolerite.base-onchain-tools/base-onchain-tools is a hosted endpoint at https://base-onchain-tools.dolerite.workers.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 12 exposed · ~1,396 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
base_address_check ~102

Pre-flight check on a Base mainnet address before you pay it: contract vs EOA, ETH and USDC balances, outbound tx count, and warnings about whether funds sent there can actually be moved. Costs $0.002 per call, paid in USDC over x402 on Base. Calling this tool returns the payment requirements; failed calls are never billed.

NameTypeReqDescription
addressstringyesBase mainnet address (0x-prefixed, 20 bytes)

No output schema declared.

No examples provided.

base_allowance ~124

ERC-20 allowance on Base: how much a spender may pull from an owner, whether it is an unlimited approval, the owner balance, and how much is actually spendable right now. Defaults to USDC. Costs $0.001 per call, paid in USDC over x402 on Base. Calling this tool returns the payment requirements; failed calls are never billed.

NameTypeReqDescription
ownerstringyesToken holder address
spenderstringyesAddress allowed to spend
tokenstringOptional ERC-20 contract, defaults to USDC on Base

No output schema declared.

No examples provided.

base_contract_audit ~247

What an UNVERIFIED Base contract can actually do — the case where block explorers show you nothing. Disassembles the deployed bytecode with a PUSH-aware opcode walk (a naive byte scan reports SELFDESTRUCT on contracts that cannot self-destruct), strips the Solidity metadata trailer, recovers the function selectors from the dispatch table and names them against a keccak-derived signature database, then reports admin powers (mint, blacklist, freeze, pause, trading switches, adjustable fees, upgrade hooks), dangerous opcodes (DELEGATECALL, SELFDESTRUCT, CALLCODE, CREATE2), which token standards it really implements, and whether it supports EIP-3009 so it can be paid gaslessly over x402 at all. Proxies are detected and followed, because a forwarder's own bytecode tells you nothing. Costs $0.04 per call, paid in USDC over x402 on Base. Calling this tool returns the payment requirements; failed calls are never billed.

NameTypeReqDescription
addressstringyesContract address on Base mainnet
follow_proxystringOptional, default true. Set to false to audit the proxy's own bytecode instead of its implementation.

No output schema declared.

No examples provided.

base_contract_type ~106

Identify what a Base contract actually is: ERC-20, ERC-721 or ERC-1155 via ERC-165, plus proxy detection across EIP-1967, EIP-1822 and the legacy ZeppelinOS slot with the current implementation address. Costs $0.002 per call, paid in USDC over x402 on Base. Calling this tool returns the payment requirements; failed calls are never billed.

NameTypeReqDescription
addressstringyesContract address on Base mainnet

No output schema declared.

No examples provided.

base_demo ~51

Free. Returns a complete, live contract audit of Base USDC — the same output shape as the paid audit tool, with the address fixed. Call this first to see what the paid tools return before spending anything.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

base_gas ~79

Live Base mainnet gas oracle: current gas price, base fee, recent base fee trend, priority fee percentiles, and the estimated cost of a plain ERC-20 transfer in ETH. Costs $0.001 per call, paid in USDC over x402 on Base. Calling this tool returns the payment requirements; failed calls are never billed.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

base_portfolio ~91

ETH and USDC balances for up to 20 Base addresses in a single call, with per-address funded flags and totals. One request instead of forty RPC round trips. Costs $0.003 per call, paid in USDC over x402 on Base. Calling this tool returns the payment requirements; failed calls are never billed.

NameTypeReqDescription
addressesstringyesComma-separated Base addresses, max 20

No output schema declared.

No examples provided.

base_price ~80

ETH/USD and BTC/USD read live from Chainlink's on-chain price feeds on Base, with the feed's own description, decimals, update timestamp, age in seconds and a staleness flag. Costs $0.001 per call, paid in USDC over x402 on Base. Calling this tool returns the payment requirements; failed calls are never billed.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

base_simulate_transfer ~201

Will this token payment actually go through, and if not exactly why. Simulates the transfer without spending gas, decodes the real revert reason (Error(string), Panic codes translated to English, or a custom error selector), and separately reports balance and allowance blockers. Understands that a caller with no ETH is fine for gasless EIP-3009 or a sponsored relayer. Costs $0.008 per call, paid in USDC over x402 on Base. Calling this tool returns the payment requirements; failed calls are never billed.

NameTypeReqDescription
amountstringyesAmount in atomic units (for USDC, 1000000 = $1)
fromstringyesAddress the tokens leave
spenderstringOptional: simulate transferFrom pulled by this spender instead of a direct transfer
tostringyesRecipient address
tokenstringOptional ERC-20 contract, defaults to USDC on Base

No output schema declared.

No examples provided.

base_token ~81

ERC-20 token metadata on Base mainnet: name, symbol, decimals and total supply, read straight from the contract. Costs $0.001 per call, paid in USDC over x402 on Base. Calling this tool returns the payment requirements; failed calls are never billed.

NameTypeReqDescription
addressstringyesERC-20 contract address on Base mainnet

No output schema declared.

No examples provided.

base_token_price ~137

USD price for ANY token on Base, not just the two assets Chainlink covers. Discovers every Uniswap V3 pool against WETH and USDC across all four fee tiers, reads sqrtPriceX96 and does the Q96 fixed-point maths, prices off the deepest pool, ignores deployed-but-never-traded pools, and cross-checks the remaining ones to flag thin or manipulated liquidity. Costs $0.006 per call, paid in USDC over x402 on Base. Calling this tool returns the payment requirements; failed calls are never billed.

NameTypeReqDescription
addressstringyesERC-20 token address on Base mainnet

No output schema declared.

No examples provided.

base_tx_check ~97

Confirm a Base mainnet transaction: success or reverted, block, confirmations and finality, gas used, and every ERC-20 transfer it moved with USDC amounts decoded. Costs $0.002 per call, paid in USDC over x402 on Base. Calling this tool returns the payment requirements; failed calls are never billed.

NameTypeReqDescription
hashstringyesBase mainnet transaction hash (0x-prefixed, 32 bytes)

No output schema declared.

No examples provided.
