Run Arweave GraphQL queries in Claude Desktop

Stop copying long GraphQL payloads from your terminal into your chat window. This MCP Server lets Claude Desktop run complex queries over the permaweb using `query_graphql` to find specific files, tags, or transaction histories. Your agent handles the raw JSON responses, parsing out exactly what you need without manual intervention. It makes searching the immutable web as fast as asking a question.

Check storage prices and wallet balances instantly

Calculating permaweb deployment costs usually requires manual math or hunting down conversion tools. Now, your agent uses `get_storage_price` to fetch the exact cost in Winstons for any file size you specify. Pair that with `get_wallet_balance` and `get_wallet_last_tx` to let Claude Desktop verify if your local wallet has enough funds before attempting a deploy. This MCP tool keeps your deployment planning fast and accurate.

Inspect blocks and transaction data locally

Digging into raw blockchain data can slow down your debugging process. This integration lets you pull specific transaction details using `get_transaction` and raw payloads via `get_transaction_data` without leaving your workspace. If you need to trace network health or block details, the agent calls `get_block_by_hash` or `get_block_by_height` directly. You get deep network visibility through a simple conversational interface.
