Unverified: 6 categories

Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm. Claim this server and supply a read-only token to verify it and lift the score.

MCP tools · 146 exposed · ~20,604 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 →

audit_bot_code ~77

eth_call with your own calldata against one pinned public node: raw return data plus its decoded uint/address forms. The escape hatch for any view function we did not wrap.

Bytecode size plus every supported-interface answer in one call — the pre-flight that tells an agent whether a 'token' address is a contract at all and which standards it claims. Costs $0.001 USDC per call. Chains: base, ethereum, arbitrum, bsc, polygon, optimism, avalanche.

chain_fee_history ~152

eth_feeHistory over a bounded window: base fee at every block plus the 25/50/75 priority-fee percentiles. Whether gas is RISING is not answerable from one instantaneous quote, which is what /chain/fee-data gives. Costs $0.001 USDC per call.

chain_logs ~306

eth_getLogs over a bounded window (max 1000 blocks) with an address and/or first topic — transfers and events without running an indexer. Refuses an unfiltered scan. Walks the window in chunks because a free node refuses a big one on response size, and reports any range no node would serve instead of failing a settled call. Costs $0.001 USDC per call. Chains: base, ethereum, arbitrum, bsc, polygon, optimism, avalanche. Byte-identical to GET /chain/logs?chain=base&address=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913&topic0=0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef&fromBlock=5000&toBlock=5999.

chain_multicall ~256

Batched eth_call: ten (target, calldata) pairs settled once, each answered independently so one reverting view cannot fail the rest. A tenth of the per-call cost of doing them one at a time. Costs $0.001 USDC per call. Chains: base, ethereum, arbitrum, bsc, polygon, optimism, avalanche. Byte-identical to GET /chain/multicall?chain=base&calls=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913:0x95d89b41,0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913:0x18160ddd&blockTag=latest.
