Overview

AI-generated overview

Indexfy lets an assistant browse, quote and prepare USDC trades for fully backed crypto index funds and YES/NO prediction markets on Base.

What you can do
  • List and inspect index funds, including mandate, holdings, weights, price, TVL and performance
  • Check a wallet's index holdings, profit/loss and Indexfy points
  • Build transactions to create, buy or sell index funds and to register a new index
  • List and inspect prediction markets, and quote YES/NO share trades with fees
  • Build trades, market creation, resolution steps (propose, dispute, finalize, redeem, withdraw liquidity) and solver stake deposits or withdrawals
  • Return unsigned calls with a simulation result for the wallet to sign and send
When to use it
Useful when someone wants an assistant to research Indexfy index funds or prediction markets on Base and prepare the corresponding USDC transactions, or to walk through a market's lifecycle steps, without leaving the chat.
Requirements
A remote streamable HTTP endpoint; no package, API key or environment variable is declared. A Base (chain id 8453) wallet address is passed to the tools, and the user must sign and send the returned calls themselves, for example with EIP-5792 batching. USDC is needed for buys, seeding and stakes.
Before you install
Everything here moves real money: buys, sells, index seeding, market liquidity (minimum 100 USDC), 1% solver bonds and dispute bonds. The build_ tools do not send transactions, so the user must review each call and the simulation status before signing. Creating an index or market requires registering it afterwards, and market registration must happen within 1 hour. Prediction markets are stated as unavailable to users in the US, Portugal, France, Spain, Italy and China.

Installation

In SourceWeft

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

Web executable via Streamable HTTP. 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/xyz.indexfy%2Findexfy/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
