Editing is the point
Read what's already on chain, change the metadata, push it back. That's the part that gets used most, and it works the same way on Solana and on the EVM side.
MCP server · Non-custodial
Mint & edit NFTs from your chat. On six chains.
acunya is an MCP server for Claude and ChatGPT. It builds the transaction, your wallet signs it, and the art lives on Arweave. Mint something new, or fix what you already own: NFTs, tokens, whole collections.
How it works
Three steps, one signature.
- 1build
acunya writes the unsigned transaction and tells you what it costs.
- 2sign
Your wallet signs it. The keys stay with you.
- 3broadcast
acunya sends it and hands back the signature.

What it does
Health check & repair
We fetch the metadata and the image through the same gateways marketplaces use, then list whatever came back broken. The diagnosis is free.
Your wallet signs. Always.
acunya never holds your keys and never signs for you. It builds unsigned transactions, and broadcasts the ones that come back signed.
Permanent art on Arweave
Drop an image on a one-time link, up to 25 MB. It goes to Arweave and stays there.
You see the cost before you sign
Every tool that spends returns what it will cost, in the response, before anything is broadcast.
acunya charges no service fee. You pay only the network's own costs (Solana rent, EVM gas), shown before you sign; storage uploads are quoted upfront. Reads, nonce, account closes and broadcast are free.
