Ankr API MCP Server

Read a wallet's tokens and NFTs, a token's price and its holders, and raw blocks, logs and transactions across chains, with the chain named per call.

LABSCO SUMMARY

The read surface splits along Ankr's plan line, and the history and holder-list questions — the ones an audit starts with — sit on the paid side of it.

Balances, current prices, NFT ownership and metadata, block data, event logs and single-transaction lookups are on the plain path; the tools marked Premium API are the ones that answer "who held this" and "what did it do over time". Worth knowing before you plan a workflow around it: nothing in this list signs or sends anything — every call is a get_ — so ANKR_API_TOKEN is an API credential and no wallet key goes near the server. Chain selection is per call rather than per session, through blockchain or network, which is what lets get_nfts_by_owner and get_token_transfers work across blockchains rather than a chain at a time.

What it is

A read-only chain-data server over the Ankr API: balances and NFT holdings for an address, token prices and their derivation, holder lists, transfer history, and block, log and transaction reads, each scoped by a blockchain or network argument.

What you get

  • Holdings for an address: get_token_balances returns coin and token balances with USD values on a given network, and get_nfts_by_owner returns the NFTs a wallet holds across blockchains.
  • Pricing with its derivation attached: get_token_price returns the current USD price and falls back to the native coin when contractAddress is omitted, get_token_price_history returns prices over an interval between fromTimestamp and toTimestamp, and explain_token_price breaks a price down into the liquidity pools and pairs behind it at a given blockHeight.
  • Holder-side views: get_token_holders lists holder addresses for a token, get_token_holders_count returns the holder count with historical data, and get_nft_holders lists the wallets holding a collection.
  • Transfer history paged by block or by time: get_token_transfers and get_nft_transfers take fromBlock/toBlock or fromTimestamp/toTimestamp with descOrder, and page through pageSize and pageToken.
  • Raw chain reads: get_blocks returns full block data for a range with includeTxs, includeLogs, decodeTxData and decodeLogs; get_logs filters event logs by address and topics; get_transactions_by_hash resolves a hash and can search across blockchains.
  • Address forensics: get_interactions lists the blockchains an address has touched, get_account_balance_historical returns a wallet's balance at a blockHeight, and get_internal_transactions_by_block and get_internal_transactions_by_parent_hash surface contract-to-contract calls.
  • Chain-level context: get_blockchain_stats returns total transactions, block time and native coin price, and get_currencies lists the tokens available on a blockchain.

Requirements

An Ankr API token, supplied as ANKR_API_TOKEN. The calls whose descriptions are marked Premium API additionally need a plan that covers them: get_token_holders, get_token_holders_count, get_token_transfers, get_token_price_history, explain_token_price, get_nft_holders, get_nft_transfers, get_transactions_by_address, get_internal_transactions_by_block and get_internal_transactions_by_parent_hash, with get_account_balance_historical marked Premium/Early Access.

Setup effort

One command plus a key — npm install @akki91/ankr-mcp, then supply credentials
