Connect to the TzKT API, the most advanced indexer for the Tezos blockchain. This MCP server allows your AI agent to query live on-chain data, analyze smart contract storage, and track financial operations across Mainnet and testnets.

What you can do

  • Account Exploration — List accounts by balance or activity and fetch detailed profiles including balance history.
  • Smart Contract Auditing — Inspect contract code (Michelson/Micheline), current storage, and available entrypoints for any KT1 address.
  • Transaction Tracking — Search operations by hash or list transactions with advanced filters like sender, target, and amount.
  • Financial Reporting — Generate JSON-based activity reports for specific Tezos addresses.
  • Multi-Network Support — Seamlessly switch between Mainnet, Ghostnet, and Shadownet.

How it works

  1. Subscribe to this server
  2. (Optional) Enter your TzKT API Key for higher rate limits
  3. Start querying the Tezos ledger from Claude, Cursor, or any MCP-compatible client

Who is this for?

  • Web3 Developers — Debug smart contracts and verify storage states directly from your IDE.
  • Data Analysts — Extract historical balance data and transaction flows for Tezos accounts.
  • DeFi Users — Monitor wallet activity and track specific operation hashes without leaving the chat interface.

List the top 5 accounts on Tezos mainnet with a balance greater than 1000 XTZ.

I've queried the mainnet accounts. Here are 5 accounts with balances over 1000 XTZ, including tz1... (Balance: 1500 XTZ) and tz1... (Balance: 1200 XTZ). Would you like to see the full report for any of these?

What are the available entrypoints for the smart contract KT1PWx2mnDuep3UMCcAgST9SetSjSEu7RZK1?

I've retrieved the entrypoints for that contract. It features several callable functions including 'transfer', 'mint', 'burn', and 'set_metadata'. Which one would you like to inspect further?

Get the details for the Tezos transaction with hash ooVp... on Ghostnet.

Searching Ghostnet for operation ooVp... Found it! This was a transaction of 50 XTZ from tz1... to tz1... confirmed at block level 1,234,567. The status is 'applied'.

Yes! Use the `get_account_balance_history` tool with the account address. It will return a historical record of balance changes for that specific Tezos address.
