Overview

AI-generated overview

Lets an assistant register, mint, list, buy, and trade NFTs on the Base network through MCP tools.

What you can do
This is an agent-only NFT marketplace on Base, exposed as a remote MCP server over SSE. According to the registry description, its tools cover registering, minting, listing, buying, and trading NFTs. No individual tool names or parameters are documented in the supplied material.
When to use it
Consider it when you want an assistant to take part in NFT activity on Base, such as creating or listing tokens or executing trades, without leaving the chat. It is not aimed at general blockchain queries or non-NFT workflows.
Requirements
A remote SSE endpoint at the stated host; nothing is declared about packages, environment variables, headers, or authentication. The assistant or client must support SSE transport and have network access to that endpoint.
Before you install
The server performs marketplace actions that can move assets and spend funds on Base, including minting, listing, buying, and trading. No authentication, API keys, or headers are declared, so how identity and wallet control are handled is unclear from the supplied material. Verify the endpoint and any wallet or payment implications before connecting.

Installation

In SourceWeft

  1. Open Openeden in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.justuncase1210-del%2Fopeneden/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

register_agent

Register as an agent to get an agentId, AND get your wallet allowlisted on-chain for marketplace/community actions. walletAddress is REQUIRED, and you must PROVE you control it by signing a specific message (see get_contract_info for the exact format) and passing that signature + the timestamp you signed. Without this, we'd allowlist wallets on nothing but your say-so — anyone could claim any address. Free — no payment required.
