Trust breakdown (6 categories)

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →

Endpoint Security57

The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
Authorisation not fully verified: no authorisation is required to call this server, and 11 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail

Transport & Reachability100

Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass

Schema Quality & AI Usability65

AI-judged instruction clarity (good).Pass
Context-footprint check failed: tool/resource definitions use about 1679 tokens (~139/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 Management27

Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

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
Structured output schemas are declared (92% of tools); any adoption earns full credit.Pass

Capabilities100

Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

MCP tools — 12 exposed · ~1,679 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.

Tool Tokens

decode_tx Explain a transaction ~137

Decode what a transaction did: delegated heimdall decode plus `decoded_call` from the resolved target ABI when available. Prefer `decoded_call` for typed function/arg names, and read its provenance.

Input Output Examples

Name	Type	Req	Description
chain	—	yes	Chain alias from GET /v1/chains (for example "ethereum", "base", "monad", "bsc") or numeric EIP-155 chain id.
rpc_url	string	—	Override HTTP(S) RPC URL. Required for chains with no default (e.g. local/31337) or custom EVM chain ids.
tx_hash	string	yes	0x transaction hash.

Name	Type	Req	Description
cached	boolean	yes	—

Encode a function call to calldata (0x…) without sending anything.

Input Output Examples

Name	Type	Req	Description
address	string	yes	0x contract address.
args	array	—	Function arguments, in order. Pass uint values as decimal strings.
chain	—	yes	Chain alias from GET /v1/chains (for example "ethereum", "base", "monad", "bsc") or numeric EIP-155 chain id.

No examples provided.

export_registry Export selector commons ~31

Return the CC0 selector commons as NDJSON. This can be large; prefer lookup_selector for normal agent workflows.

Input Output Examples

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

list_chains List supported chains ~112

List viem-backed chain aliases and ids. Use filters to find testnets, default-RPC chains, or a named chain before resolving contracts.

Input Output Examples

Name	Type	Req	Description
has_default_rpc	boolean	—	When true, only chains gulltoppr can query without rpc_url.
q	string	—	Search by chain id, name, alias, or native symbol; multi-word queries also match token-by-token and without whitespace.
testnets	boolean	—	When true, only testnets; when false, only mainnets.

Name	Type	Req	Description
chains	array	yes	—

No examples provided.

lookup_selector Lookup selector commons ~60

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

Input Output Examples

Name	Type	Req	Description
selector	string	yes	4-byte function/error selector or 32-byte event topic0.

Name	Type	Req	Description
entries	array	yes	—
selector	string	yes	4-byte function/error selector or 32-byte event topic0.

No examples provided.

prepare_tx Prepare an unsigned transaction (hand-off) ~294

Prepare a contract WRITE for the user to sign. 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.

Input Output Examples

Name	Type	Req	Description
address	string	yes	0x contract address.
args	array	—	Function arguments, in order. Pass uint values as decimal strings.
chain	—	yes	Chain alias from GET /v1/chains (for example "ethereum", "base", "monad", "bsc") or numeric EIP-155 chain id.
from	string	yes	The sender address (the user's wallet). No key is needed — nothing is signed.
function	string	yes	Function name, or full signature like "transfer(address,uint256)" if overloaded.
rpc_url	string	—	Override HTTP(S) RPC URL. Required for chains with no default (e.g. local/31337) or custom EVM chain ids.
value	string	—	Native value in wei (decimal string), for payable functions.

args	array	—	Function arguments, in order. Pass uint values as decimal strings.
chain	—	yes	Chain alias from GET /v1/chains (for example "ethereum", "base", "monad", "bsc") or numeric EIP-155 chain id.
function	string	yes	Function name, or full signature like "transfer(address,uint256)" if overloaded.
rpc_url	string	—	Override HTTP(S) RPC URL. Required for chains with no default (e.g. local/31337) or custom EVM chain ids.

Name	Type	Req	Description

Name	Type	Req	Description
bytecodes	integer	yes	—
selectors	object	yes	—

No examples provided.

resolve_abi Resolve contract ABI ~315

Resolve a contract's interface from chain + address via a fallback ladder (Etherscan → Sourcify → proxy → heimdall decompile → 4byte). 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.

Input Output Examples

Name	Type	Req	Description
address	string	yes	0x contract address.
chain	—	yes	Chain alias from GET /v1/chains (for example "ethereum", "base", "monad", "bsc") or numeric EIP-155 chain id.
method_kind	string	—	Restrict manifest methods to read, write, or all.
method_limit	integer	—	Maximum number of manifest methods to return after filtering.
method_q	string	—	Case-insensitive manifest method search across names, signatures, parameters, outputs, and hints.
rpc_url	string	—	Override HTTP(S) RPC URL. Required for chains with no default (e.g. local/31337) or custom EVM chain ids.

Name	Type	Req	Description
abi_for	—	yes	—
