Read-only perp futures data: all-in trading cost, venue fees, funding rates and volume ranking

VerifiedStreamable HTTPWeb executableFinanceData & Analytics

Overview

AI-generated overview

Read-only perpetual futures data: compare venues by measured all-in trading cost, fees, funding rates, volume ranking and jurisdictional access.

What you can do
Compare venues by measured all-in cost of a perp market buy, with unfillable or unconfirmed rows listed separately with reasons. Look up one venue's maker and taker fees, volume fee ladder, leverage and funding terms, each with source and check date. Get current funding rates per asset across venues, normalized to an hourly rate, with interval, open interest and price. Rank CEX and DEX perp venues by reported and adjusted volume, with dated reasons for hold-outs. Check what venues and a local regulator publish about perp access in one jurisdiction.
When to use it
Useful when comparing where to trade a perpetual future and what it really costs, checking funding and fee terms before a position, or reviewing venue volume and access rules for a jurisdiction.
Requirements
Remote streamable HTTP endpoint; no packages, environment variables or headers declared. Network access to the endpoint.
Before you install
Data is read-only and measurements are not accusations; access results are not legal advice and should be verified against the cited sources. Costs and funding rates are stored snapshots and may be stale.

Installation

In SourceWeft

  1. Open PerpFinder 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/com.perpfinder%2Fperpfinder/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

Add this to your client's mcpServers config.
