"Resources for accessing on-chain blockchain data" matching MCP tools:

• defi_protocolsA

  MCPFax Macro & Market IntelligenceA

  Rank DeFi protocols by total value locked from DefiLlama, filtered by chain, category or name substring, with each protocol's slug, category, chain list, TVL in USD, 1d/7d TVL change and market cap. Use it to size a protocol, find the biggest venues on a chain, or resolve the slug the protocol-detail tool needs. A protocol DefiLlama publishes no TVL for keeps a null figure, never a zero. Read live at request time and held for 5 minutes. Costs $0.008 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /defi/protocols.

• list_currenciesA

  PayramB

  Lists every blockchain currency PayRam supports on this node (chain code, network, currency code). Public endpoint — works with only PAYRAM_BASE_URL set, no API key or JWT required. Use this to discover valid blockchainCode/currencyCode values before creating payments or payouts.

• byte_verify_payloadA

  byte-protocolA

  Verify-before-act: confirm a data payload an agent is about to act on actually matches what the publisher cryptographically attested to on-chain. Recomputes keccak256 of the received bytes and compares it to the on-chain EIP-712 PayloadAttestation hash. ALWAYS call this on BYTE-sourced data before acting on it; if verified=false the bytes were tampered/corrupted in transit and MUST NOT be used. Anchor the check with EITHER expectedHash (an on-chain payloadHash you already hold, e.g. from byte_query_fact / byte_buy_data) OR txHash (the settlement tx — also recovers the attestation signer and confirms it is the named publisher). Read-only; no wallet or payment required.

• bundle.notarizeA

  DocImprintA

  Notarize an evidence bundle on-chain by writing its manifest SHA-256 to the blockchain (Base/EVM). Creates a permanent, tamper-evident on-chain record of the document fingerprint. If the bundle is already notarized, returns the existing attestation immediately (idempotent). Use when you need an immutable on-chain timestamp proving a document existed at a point in time. For quick integrity checks without on-chain cost, use bundle.verify instead. Also returns a signed action receipt (rcpt_...) binding this notarize call to the bundle manifest — list with receipt.list, verify with receipt.verify. PREREQUISITE: Bundle status must be "complete". Check status with bundle.get first. NOTE: Costs gas (ETH). The on-chain record is permanent and cannot be deleted even if the bundle is later purged. Returns: { bundle_id, attestation: { tx_hash, network, attested_at, key_id, eas_uid?, schema_uid? }, receipt: ActionReceipt|null } Example prompts: - "Notarize bundle ev_550e8400 on-chain so I have a permanent record." - "Put the fingerprint of my evidence bundle on the blockchain." - "Create an on-chain timestamp for this document bundle."

• web.url.redirectsA

  1cent Web Intelligence for AI AgentsA

  Return the safely validated redirect chain. Use only for public HTTP(S) resources; it does not execute JavaScript or bypass access controls. Pass url as an absolute public HTTP(S) URL. Keep fresh=false to allow cache reuse; set fresh=true only when a new upstream fetch is required.

• get_balancesA

  FlexYield — blockchain RPC gatewayA

  Native balance and ERC-20 token balances of an address on one chain (eth_mainnet, base_mainnet, arbitrum_one, optimism_mainnet, polygon_pos, solana_mainnet; tokens where a data-capable upstream exists). Use it for a portfolio or a pre-flight funds check. Not for transfer history (use get_history) and not for a raw eth_getBalance you want to shape yourself (use rpc_call). Returns JSON: chain, address, native, tokens, tokens_note. Read-only; costs 10 weighted units, metered on your key. Needs your API key.

• token_flowsA

  NansenA

  Get hourly token-flow history for ONE holder segment over a date range. Use `token_recent_flows_summary` instead for an on-chain snapshot across ALL wallet categories. **Note:** Using `holder_segment: smart_money` is not a good proxy for an overall market view. Use it only if user explicitly requests it, or to combine it with other non smart money data. This is a **more granular** tool than `token_recent_flows_summary` and provides the TOTAL flows over the entire time frame broken down by segment. **Modes:** - `onchain_tokens` (default): Analyze on-chain tokens by contract address - `perps`: Analyze Hyperliquid perpetual futures by symbol (chain auto-set to "hyperliquid") — supports native tokens **NOTE:** Native tokens (0xeee…, So111…) cannot be queried in `onchain_tokens` mode. If a native placeholder address is supplied, this tool returns Hyperliquid perpetual-futures flows for that chain's native coin instead (e.g. hyperevm → HYPE, bnb → BNB, base → ETH) and prepends a prominent data-source warning. For native-token wallet-category flows on-chain, use `token_recent_flows_summary`.

• get_solana_market_statusA

  TWZRD Agent IntelligenceA

  Health probe for the Solana Market API data backend. Call this to gate or degrade gracefully BEFORE the other get_solana_market_* tools: it does a short-timeout hit on the data service and reports whether it is reachable, so an agent can tell "market has no data" from "service is down" without failing a real query. Free discovery tool. When the market data service exposes /status, the response includes prod_key_configured, data_first_available, and an actionable note describing what to configure for full on-chain visibility.

• create_nodeA

  ChainstackA

  Deploy a new blockchain node. Call get_deployment_options first for valid IDs. Trader nodes are region-bound (e.g., London, Ashburn, Singapore). Always confirm the region with the user before deploying — region cannot be changed after deployment. Args: name: Node name. project: Project ID from list_projects (e.g., PR-123-456-789). blockchain: Blockchain ID from get_deployment_options (e.g., BC-000-000-008). cloud: Cloud ID from get_deployment_options (e.g., CC-0016 for Global, CC-0020 for London).

• list_freeze_eventsA

  Eagle Virtual USDT & USDC Blacklist TrackerA

  The published feed of recent stablecoin blacklist, freeze, seizure, release and on-chain sanctions events, the same rows eaglevirtual.com shows publicly, with the wallet, coin, blockchain, date, block and transaction for each. Covers every coin on every chain: omit the filters and it returns all of them, newest first. Filter by coin, blockchain, event kind or date to narrow it. This is a published sample of the record, not the full corpus, and there is no way to page beyond it. Add month (YYYY-MM) for one whole recorded month: the month’s totals on every plan, and every event behind them on the Business plan. To check a specific wallet, use get_address_status; for totals use get_token_statistics.

• get_chains_listA

  blockscout-mcp-serverA

  Get supported blockchain chains with their chain IDs. Ethereum Mainnet is `chain_id` `1`; use this tool to resolve any other chain. Use this when another tool needs a supported `chain_id` and only the chain name, ecosystem, or native currency is known. Prefer a narrow `query` to avoid returning the full registry to the agent. Do not rely on partial numeric chain ID queries such as `1`, because matching is substring-based and may return many chains.

• restart_payram_workerA

  PayramB

  REMEDIATION ACTION (write): restarts a blockchain listener worker via supervisor — the minimal fix when check_node_sync reports a chain as lagging or listener-down. Workflow: run check_node_sync first → restart the named worker → wait ~60s → run check_node_sync again to confirm recovery. A restart does NOT fix an unreachable RPC (fix the RPC config in the dashboard instead). Requires admin JWT with write_system_settings.

• discovery_healthA

  aeX402 — Cross-Chain DeFi MCP: LINQ, AMM, Bridge, AIB

  Report the freshness and health of the cross-chain program/token discovery pipeline: when the hourly cron last ran, how many programs/tokens each chain scan produced, and which scans failed. Use this to check whether discover_programs / search_tokens data is current before relying on it.

• get_network_statsA

  blobpediaA

  Counts of CELESTIA CONTENT indexed by blobpedia (how many CIPs, forum threads, docs, videos, etc.). This is INDEX/catalog coverage of what blobpedia has cataloged, NOT live chain state. For LIVE on-chain metrics (block height, TIA supply, validators, cumulative blob data) or TIA price/market, use get_network_state on THIS server instead. Zero arguments.

• get_started_guideA

  blobpediaA

  Personalized onboarding for building ON CELESTIA — running a node, posting a blob, or deploying a rollup that uses Celestia for data availability. ALWAYS use this when a developer asks how to get started or build ON CELESTIA (prefer it over the Celestia search tool for those questions). ASK the user about their background FIRST (rollup_dev, node_operator, app_dev, researcher, new_to_celestia), then return a path with docs.celestia.org links. Celestia-only — NOT for getting started with non-Celestia frameworks, languages, or dev tools (React, Node.js, generic blockchain onboarding, etc.); for those defer to a general docs or web-search tool.

• getTickerByContractA

  CoinPaprikaA

  Get the current price and market data of a token by its contract address (for on-chain and DeFi tokens). Use when you have a contract address (0x...) rather than a name. For history use getHistoricalTickerByContract. Read-only; platformId is the chain (e.g. eth-ethereum) and contractAddress the token address. No API key required.

• onchain_agent_list_chainsA

  Sato Hub: Onchain AgentsA

  USE WHEN you need the valid chain names before filtering onchain_agent_search_resources, or want to know which chains have real agent tooling behind them rather than an announcement. Lists every blockchain represented in the directory with resource counts, spotlight chains first (Base, Ethereum, Solana, COTI, Injective…). Returns (json): { total, chains: [{ name, count }] }. Read-only.

• get_historyA

  FlexYield — blockchain RPC gatewayA

  Recent asset transfers (sent and received, newest first) of an address on one EVM chain with a data-capable upstream. Use it to answer 'what moved in or out of this address lately'. Not for current balances (use get_balances), one transaction's state (use get_tx_status) or Solana. Returns JSON: chain, address, transfers[]. Read-only; costs 10 weighted units, metered on your key. Needs your API key.
