Prefer `decoded_call` for typed function/arg names, and read its provenance.
encode_call

argschain*valueaddress*rpc_urlfunction*
Encode a function call to calldata (0x…) without sending anything. Encode a function call to calldata (0x…) without sending anything.
export_registry

Return the CC0 selector commons as NDJSON. This can be large; prefer lookup_selector for normal agent workflows. Return the CC0 selector commons as NDJSON. This can be large; prefer lookup_selector for normal agent workflows.
list_chains
read-only
qtestnetshas_default_rpc
List viem-backed chain aliases and ids. Use filters to find testnets, default-RPC chains, or a named chain before resolving contracts. List viem-backed chain aliases and ids. Use filters to find testnets, default-RPC chains, or a named chain before resolving contracts.
lookup_selector

selector*
Lookup gulltoppr-proven signatures for a 4-byte function/error selector or 32-byte event topic0. Prefer these over public 4byte guesses. Lookup gulltoppr-proven signatures for a 4-byte function/error selector or 32-byte event topic0. Prefer these over public 4byte guesses.

Returns an UNSIGNED transaction, its simulation, a human-readable summary, safety metadata, warnings, a configured signing deeplink, and an EIP-1193 wallet request when signing is recommended. IMPORTANT: this tool NEVER signs or broadcasts. Present the summary + simulation + warnings to the user. Only hand them the `deeplink` or `wallet_request` when `safety.signing_recommended` is true. If `safety.risk_level` is high or blocked, make that explicit; blocked means do not send.
read_contract

argschain*address*rpc_urlfunction*
Call a view/pure function and get the decoded result. No wallet, no cost. Rejects state-mutating functions. Call a view/pure function and get the decoded result. No wallet, no cost. Rejects state-mutating functions.

Returns a compact capability manifest (read vs write functions, the 'buttons'), proxy chain, token metadata, and PROVENANCE. ALWAYS read `provenance`: a `decompiled` ABI has synthetic function names — treat it with care and confirm intent before writing. Partial, proxy, and bytecode-match results lead with a WARNING before the JSON. The compact manifest/provenance is also returned as structuredContent. Use method_q/method_kind/method_limit for large ABIs. Raw ABI is omitted from MCP output to save tokens; use REST/SDK resolve_abi with include_abi=true if needed.
resolve_name

name*chain
Resolve an ENS/Basename to an address, or an address to its primary ENS/Basename. Pass chain=base for Basenames. Resolve an ENS/Basename to an address, or an address to its primary ENS/Basename. Pass chain=base for Basenames.
