Discovered
agent.card.lookup

Look up a specific AI Agent's card by ID. Returns identity, capabilities, trust score, and endpoints. ($0.002)

Discovered
agent.card.register

Register an AI Agent in the ChainRay A2A Agent Card registry. Requires agentId, name, and capabilities array. Auto-attaches KYA trust score if paymentAddress provided. Returns registration status. ($0.05)

Discovered
agent.erc8004

Get agent reputation in ERC-8004 standard format (Identity + Reputation + Validation Registry schema). Same KYA analysis but formatted for on-chain registry compatibility. ($0.025)

Discovered
agent.reputation

KYA (Know Your Agent): 10-factor on-chain reputation scoring. Evaluates transaction volume, balances, token diversity, DeFi interactions, cross-chain intel, and risk flags. Returns trust score (0-100) and trust level. ERC-8004 compatible. Scope: Agent or wallet collaboration trust and reputation signals, including ERC-8004-compatible evidence. Use this before relying on another Agent. It is not a wallet's financial activity score (wallet.credit_score), a registered identity card (agent.card.lookup), or proof that the subject is a verified person or organization.

Discovered
analyze.recent_interactions

Show addresses that interacted with a target in recent ~2000 blocks. Labels known entities (CEX, DEX, bridges). EVM only.

Discovered
analyze.risk_dashboard

Get a unified risk assessment for any address: combines contract security scan, token approval risks, and market liquidation stress into one composite risk score. Scope: composite decision view for one wallet or contract, combining contract, approval, and liquidation-risk signals. Use this when the agent wants one prioritized address risk summary. Use security.contract.scan, token.approval, or wallet.credit_score when it needs one focused dimension instead.

Discovered
analyze.tx_decode

Decode a transaction: value, gas cost, status, method ID, and whether it's a contract call.

Discovered
chain.block

Get latest or specific block data including gas, transactions, and timestamps. Use for exact latest or historical block facts on one chain, including block number, gas, transactions, and timestamps. Do not use it for an aggregate chain health view; use chain.health for a single chain or oracle.chain_status for multi-chain status.

Discovered
chain.bridge.flow

Analyze cross-chain bridge capital flow direction. Determines if a chain is seeing net capital inflow (bullish) or outflow (bearish). Use for directional net capital flow across bridges on one chain. For large bridge-transfer detection, use chain.bridge.monitor; use chain.compare when choosing between chains.

Discovered
chain.bridge.monitor

Detect large token transfers involving known bridge contracts (Across, Wormhole, official bridges). EVM only.

Discovered
chain.compare

Side-by-side comparison of EVM chains — gas costs, block time, and best DeFi yields. Helps choose the optimal chain for transactions. Use to compare a bounded set of EVM chains when selecting a network for an action. It is a decision aid, not an outage monitor or transaction executor; use chain.health for a single-chain snapshot, gas.tracker for a live fee quote, or oracle.chain_status for multi-chain status.

Discovered
chain.cross

Cross-chain wallet correlation: queries all supported EVM chains in parallel to show balance, nonce, and activity. Includes diversity score and classification.

Discovered
chain.health

Chain health score aggregating gas data, protocol TVL, and stablecoin stability. Use for a single-chain operating snapshot before choosing where to act. The score is not a contract audit or a transaction guarantee; use security.contract.scan or token.risk for safety analysis and chain.block for block facts.

Discovered
defi.aggregator

Cross-chain DeFi yield ranking: scans Aave V3 across all supported chains to find the best supply APY and cheapest borrow rates. Use for a cross-chain ranking of configured DeFi lending opportunities. For a chain-specific protocol comparison, use defi.compare; for one protocol's rates, use defi.yields.

Discovered
defi.compare

Compare DeFi lending rates across protocols. EVM: Aave V3 vs Compound V3 side-by-side. Solana: Kamino + staking yield.

Discovered
defi.farming

Get Uniswap V3 LP pool statistics including liquidity, fee tiers, and current tick data.

Discovered
defi.health

Assess DeFi protocol health: combines TVL, utilization rates, and liquidation frequency into a composite health score (0-100). Use for protocol-level DeFi health and stress signals on one chain. It does not rank yields or inspect a token contract; use defi.aggregator for cross-chain lending rankings, defi.compare for protocol rates, or token.risk for token risk.

Discovered
defi.liquidity

Read Uniswap V3 pool state for a token pair: current price, active liquidity, fee tier. EVM only. Use when a known token pair needs pool-depth and active-liquidity context. It requires both token addresses and does not rank lending yields; use defi.aggregator or defi.compare for rates.

Discovered
defi.opportunity

Find the best DeFi yield opportunity combined with optimal gas timing.

Discovered
defi.tvl

Calculate total value locked (TVL) in DeFi protocols (Aave V3, Compound V3) directly from on-chain aToken and Comet supplies.

Discovered
defi.yields

Get live DeFi lending rates. EVM: Aave V3 supply/borrow APY. Solana: Kamino KLend reserves + native staking yield.

Discovered
gas.history

Get 6-hour gas fee trend with 36 sampled data points. EVM: base fee per block. Solana: TPS performance samples. Scope: recent sampled fee history and trend. Use this for 'how have fees behaved recently?'. It is not a current quote (gas.tracker), a forecast (gas.predict), or a submission recommendation (gas.optimize).

Discovered
gas.optimize

Gas price optimization advisor: analyzes recent block patterns to recommend the best time to transact. Includes savings estimate. Scope: read-only submission-timing advice derived from current and recent fee conditions. Use this for 'when should I submit?'. It is not the raw current quote (gas.tracker), a history response (gas.history), or a standalone forecast (gas.predict).

Discovered
gas.predict

Predict near-future gas prices using moving average and trend analysis of recent block base fees. Returns prediction, trend, and recommendation. Scope: short-horizon fee forecast from recent samples. Use this for 'what may fees be soon?'. It is not a live quote (gas.tracker), historical data (gas.history), or a timing recommendation (gas.optimize), and it never executes a transaction.

Discovered
gas.tracker

Get current gas/fee data. EVM: base fee, priority fee, predictions. Solana: priority fees, TPS, congestion level. Scope: current fee snapshot for a transaction decision. Use this for 'what are fees now?'. It is not a historical series (gas.history), a short-horizon forecast (gas.predict), or timing advice (gas.optimize).

Discovered
market.dex_trades

Get recent DEX swap trades from a Uniswap V3 pool. Use for recent swaps in a known Uniswap V3 pool. It is pool-specific and read-only; use market.overview for a broad snapshot or defi.liquidity for pool state and depth.

Discovered
market.new_pairs

Discover recently created Uniswap V3 pools and inspect token metadata. Returns an explicit unavailable result when the selected chain has no configured factory.

Discovered
market.overview

Get a cross-chain market snapshot: ETH price, gas costs, and DeFi TVL across Base, Ethereum, Arbitrum, and Optimism in one call. Use for a fixed broad snapshot of major market, gas, and TVL signals. It is not a chain health verdict, token price lookup, or custom chain comparison; use chain.health, token.price, or chain.compare for those questions.

Discovered
market.solver_feed

Intent Solver decision intelligence. Provides profitability analysis, gas costs, competition level, and recommendations for ERC-7683 cross-chain intent execution. ($0.007) Use before evaluating an ERC-7683 cross-chain intent to compare gas, liquidity, competition, and estimated profitability. It does not execute the intent and should not be treated as a guaranteed quote; both source and destination must be supported EVM chains.

Discovered
market.stablecoin.monitor

Monitor stablecoin peg stability. Detects USDC/USDT/DAI price deviations from $1.00 using on-chain DEX pool data.

Discovered
market.stablecoin.supply

Get USDC/USDT/DAI total supply across chains.

Discovered
monitor.flashloan

Monitor flash loan activity on Aave V3. Detects recent flash loans with amounts and premiums paid.

Discovered
monitor.liquidation

Monitor DeFi liquidation events on Aave V3. High liquidation counts indicate market stress and potential cascading risk.

Discovered
monitor.watch.address

Create a watch on an address. Returns a wallet snapshot and watchId; use watch-diff later to receive only changed fields. Use to create the first address snapshot in a stateful watch workflow. Save the returned watchId and call monitor.watch.diff in the same MCP session for later changes.

Discovered
monitor.watch.diff

Get changes since the last check for a watched address. Returns changed fields and numeric deltas. Use only after monitor.watch.address has created a watchId in the same MCP session. It returns changes since the last check and advances the snapshot; create a new watch for a new address.

Discovered
monitor.whale.alerts

Monitor large token transfers (USDC, WETH) on EVM chains or large SOL transfers on Solana. Returns recent whale movements above a threshold.

Discovered
monitor.whale.tracker

Read recent event logs from any smart contract. Auto-decodes Transfer, Approval, Swap events. EVM only.

Discovered
security.contract.scan

Security scan a smart contract via bytecode analysis. Detects selfdestruct, delegatecall, proxy patterns, ownership. No external APIs. EVM only. Scope: bytecode-level inspection of one EVM contract for proxy, ownership, delegatecall, and selfdestruct signals. Use this for 'what does the deployed code expose?'. It is not a token market/liquidity assessment (token.risk), a wallet score, or a full audit, and it does not judge a trade by itself.

Discovered
security.contract.verify

Check if an address is a smart contract or an EOA wallet. Returns code size, balance, and classification.

Discovered
security.mev.detect

Quick sandwich attack detection. Analyzes 5 transactions before/after target in the same block. EVM only.

Discovered
security.mev.intel

Cross-protocol spread analysis with chain-specific DEX names, cost estimates, and market microstructure data. This is a heuristic estimate, not real-time mempool data.

Discovered
security.mev.shield

Pre-trade safety analysis. Evaluates sandwich attack risk, recommends optimal slippage, and suggests mitigations before executing on-chain trades. Every agent should call this before swapping. ($0.05) Scope: composite pre-trade decision for a proposed swap, bridge, or liquidity action, focused on MEV exposure and slippage mitigation. Use this before acting. It is not a historical sandwich scan (security.sandwich), a token due-diligence report (token.risk), or a transaction executor.

Discovered
security.sandwich

Batch scan an address's recent transactions for MEV sandwich attacks. Checks front-run + back-run patterns in surrounding transactions. Use to inspect historical sandwich patterns around an address. It is not a pre-trade protection decision; use security.mev.shield before a swap or liquidity action.

Discovered
token.approval

Check a wallet's ERC20 token approvals for security risks. Flags unlimited approvals and risky spender contracts.

Discovered
token.holders

Analyze top token holders by recent accumulation. Scans Transfer events to identify the largest net receivers of a token. Use for token-holder concentration and recent net accumulation. Do not use it for a wallet's portfolio or token price; use wallet.report for a wallet address or token.price for a token price.

Discovered
token.price

Get real-time token price. EVM: reads Uniswap V3 TWAP on-chain. Solana: reads Pyth oracle price account directly from chain. No external API.

Discovered
token.risk

Analyze a token's risk profile. EVM: checks contract verification, proxy status, ownership renouncement, liquidity. Solana: checks mint/freeze authority, supply, Metaplex metadata. Scope: asset-level token due diligence for a token contract or mint, combining market, liquidity, verification, and control signals. Use this when the question is 'is this token safe or liquid?'. It is not raw bytecode inspection (use security.contract.scan), a wallet's financial behavior (use wallet.credit_score), or a multi-signal address dashboard (use analyze.risk_dashboard).

Discovered
token.screener

Screen tokens by risk score and price. Returns sorted list of tokens matching criteria. EVM only.

Discovered
token.sentiment

On-chain sentiment oracle for any token/chain. Derives market sentiment from 5 on-chain signals: gas trend, gas level, momentum, chain health, ecosystem trend. No LLM. ($0.012)

Discovered
token.supply

Get ERC20 token total supply, decimals, symbol, and name from on-chain data. Use for contract-level supply metadata such as total supply, decimals, symbol, and name. It does not assess price, token safety, or holder concentration; use token.risk, token.price, or token.holders instead.

Discovered
token.trending

Get trending tokens by on-chain transfer volume. EVM only — ranks tokens by Transfer event count in recent blocks.

Discovered
token.unlock

Read token vesting/unlock schedule from on-chain contracts. Supports LinearVesting, CliffVesting, and Timelock patterns.

Discovered
util.context_brief

CaaS (Context as a Service): Aggregates real-time on-chain signals into a structured context brief for agent decision-making. Intents: swap (gas+price+whales), bridge (multi-chain gas), invest (yields+trending), monitor (whales+gas), general (all signals). No LLM cost — pure data. Use at the start of a swap, bridge, invest, monitor, or general workflow to collect the relevant signals in one structured brief. Use focused tools when the agent already knows the exact data it needs.

Discovered
util.ens_resolve

Resolve ENS domain names to Ethereum addresses (forward) or addresses to ENS names (reverse). Also retrieves text records.

Discovered
util.governance

Read on-chain DAO governance proposals. Shows last 5 proposals with vote counts and states. Supported: Ethereum, Arbitrum, Optimism.

Discovered
util.intent_router

Natural language intent routing: describe what you want to know and ChainRay selects a focused set of data services. Counts toward the client hourly MCP capacity policy; use the paid HTTP API for per-request settlement. Use when the agent has a natural-language data question and needs ChainRay to select a focused route. For deterministic workflows, call the specific tool directly; paid HTTP requests are separate from this MCP capacity policy.

Discovered
util.multi_sig

Analyze a Gnosis Safe multi-sig wallet. Returns owners, threshold, nonce, modules, and security assessment.

Discovered
util.stream_info

Get connection info for ChainRay real-time SSE streaming endpoints. These endpoints require a direct HTTP connection with text/event-stream Accept header, not MCP. Use this tool to learn how to connect. Use to discover the five real-time SSE streams and their connection requirements. The returned guidance is not a stream itself; connect directly over HTTP with the documented Accept and payment headers.

Discovered
util.verify_proof

Verify data integrity: pass a dataHash from any ChainRay response's _proof field to verify that the data was produced by ChainRay. Use after receiving a ChainRay response with _proof.dataHash to verify its integrity. It verifies a supplied hash and does not independently validate the underlying blockchain data.

Discovered
util.workflow_brief

Multi-agent workflow intelligence. Generates differentiated context briefs for each agent role in a collaborative workflow (swap, risk, bridge, settle, monitor, analysis agents). ($0.05)

Discovered
wallet.credit_score

Calculate an on-chain credit score (0-100) for any wallet. Factors: transaction history, native balance, token diversity, stablecoin holdings, DeFi activity. Returns grade (AAA to C). Scope: wallet-level financial behavior and activity score based on transaction history, balances, token diversity, stablecoins, and DeFi use. Use this for 'how active or creditworthy is this wallet?'. It is not Agent identity/reputation (agent.reputation), a registered card (agent.card.lookup), or token/contract risk.

Discovered
wallet.labels

Discovered
wallet.portfolio

Analyze a wallet's portfolio: total USD value, token breakdown, concentration analysis, and diversification score.

Discovered
wallet.profile

Profile a wallet address. EVM: ETH balance, token count, activity labels (whale/active/dormant). Solana: SOL balance, SPL token holdings, activity classification.

Discovered
wallet.report

Comprehensive address report combining wallet profile, credit score, token approvals, and recent interactions in one response.

Discovered
