Connect to the Arweave network and manage permanent data storage through natural conversation. This MCP server allows your AI agent to query the blockweave, check transaction statuses, and interact with the permaweb ecosystem.

What you can do

  • Network Monitoring — Get real-time network status, height, and peer information using get_network_info and get_peers.
  • Transaction Inspection — Retrieve transaction metadata, status, and raw data using unique IDs with get_transaction and get_transaction_data.
  • Wallet Management — Check balances in Winstons and find the last transaction for any wallet address via get_wallet_balance.
  • Storage Economics — Calculate the exact cost to store data on the permaweb with get_storage_price.
  • Advanced Querying — Use query_graphql to search for specific data and tags across the entire network.

How it works

  1. Subscribe to this server
  2. (Optional) Provide a custom Arweave Gateway URL
  3. Start querying the permaweb from Claude, Cursor, or any MCP-compatible client

What is the current status and height of the Arweave network?

I've retrieved the network info. The Arweave network is currently at height 1,542,890 with the current block hash starting with 'zX9...'. The node version is 2.7.2.

Check the balance for Arweave wallet address 3pD7...x9A.

The balance for wallet 3pD7...x9A is 1,250,000,000 Winstons, which is equivalent to 0.00125 AR.

How much does it cost to store 500MB on Arweave right now?

Calculating storage price for 524,288,000 bytes... The current cost is approximately 45,200,000 Winstons (0.0000452 AR).

You can use the `get_storage_price` tool. Just provide the number of bytes you intend to store, and the agent will return the price in Winstons (where 1 AR = 10^12 Winstons).
