MCP tools · 14 exposed · ~1,889 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
anchor_hash ~178

Anchor a 32-byte hash to BOTH Base mainnet (as EIP-1559 calldata) and Solana mainnet (via the Memo program) in a single call. Returns both transaction hashes plus block-explorer URLs as cryptographic proof of when the hash existed. Pure infrastructure — no opinions about content. Use for DAO vote receipts, AI decision attestations, contract notarization, scientific data integrity, audit trails. $0.005 USDC.

NameTypeReqDescription
dataArbitrary JSON to be canonicalized + SHA-256'd by the server. Mutually exclusive with `hash`.
hashstringPre-computed 32-byte hex hash (64 chars, no 0x prefix). Mutually exclusive with `data`.
notestringOptional 200-char note included in the response (NOT on-chain).

No output schema declared.

No examples provided.

attest_decision ~301

Attest an agent decision over (input_hash, output_hash, decision) with domain separation: supply your own wallet signature, or omit `signature`/`scheme` and the anchor-x402 treasury signs for you (ideal for wallet-less agents) — then dual-chain anchor the Merkle root on Base and Solana mainnet. Returns the signer, on-chain proof URLs, and a free re-verify URL (POST /v1/attest/verify). Use when an AI agent's decision needs a cryptographic, auditable receipt — autonomous trade approvals, AI-assisted contract decisions, model-output attestation for liability records. $0.010 USDC.

NameTypeReqDescription
decisionstringyesFree-form short label, e.g. "APPROVED", "REJECTED", "CONFIDENCE=0.93" (max 64 chars).
input_hashstringyes64-char hex SHA-256 of the agent's input.
output_hashstringyes64-char hex SHA-256 of the agent's output / decision payload.
schemestringSignature scheme (required only when you supply a signature).
signaturestring0x-prefixed hex (eip191) or base58 (ed25519). Omit to have the anchor-x402 treasury sign for you.
signer_pubkeystringRequired for ed25519 (Solana base58 pubkey).

No output schema declared.

No examples provided.

aura ~110

Aura read of any target — returns color (free-form e.g. 'molten gold with copper veins'), tier (S/A/B/C/D/F), score (0-9999), and a 2-3 sentence punchy description. Universal input — wallet, tweet, project, person, idea, meme. Use for viral / shareable content, brand vibes, social. $0.01 USDC.

targetstringyesAnything to read the aura of (max 4000 chars).

No output schema declared.

No examples provided.

decode_calldata ~148

Decode raw EVM calldata into a human-readable function name, canonical signature, and typed parameter values. Resolves the 4-byte selector against openchain.xyz's signature directory, then ABI-decodes the args. Use for tx inspection before signing, mempool analysis, debug. EVM-only (chain='ethereum'); 'solana' returns 400. $0.001 USDC.

NameTypeReqDescription
calldata_hexstringyesRaw EVM calldata (>=4 byte selector), with or without 0x prefix.
chainstringyesEVM-only; 'solana' returns 400.
contract_addressstringOptional. Reserved for future on-chain ABI lookups.

No examples provided.

decode_tx ~122

Structured decode of any mainnet transaction by hash. Supply chain ('base' | 'ethereum' | 'solana') and tx_hash. Returns from/to/value/gas/status/calldata for EVM, or slot/fee/signers/program_calls for Solana. Mined txs cached in-process. Use for tx inspection, audit, agent UX (rendering tx summaries to users). $0.001 USDC.

NameTypeReqDescription
chainstringyes
tx_hashstringyesEVM 0x+64hex or Solana base58 signature.

No output schema declared.

NameTypeReqDescription
walletstringyesEVM 0x… address (40 hex) or Solana base58 pubkey.

No output schema declared.

oracle ~102

Yes/no oracle with dual-chain anchored verdict.
