Overview

AI-generated overview

Remote MCP server giving assistants real-time crypto prices, gas fees, DeFi TVL and Polymarket odds, paid per call via x402.

What you can do
Look up real-time USD spot prices for crypto assets by symbol, CoinGecko id or chain token address, with per-coin confidence scores and roughly 15-second freshness. Compare live gas prices, base fees, priority-fee tiers and simple-transfer costs across Ethereum, Base, Arbitrum, Optimism and Polygon. Fetch current DeFi total value locked by protocol slug. Search Polymarket prediction markets by free text or slug, and list the biggest 24-hour odds movers or markets resolving soon. Read service, pricing and payment details through a free info tool.
When to use it
Useful when an assistant needs current market data rather than stale training knowledge: checking token prices, comparing gas costs before a transaction, tracking DeFi protocol size, or following prediction-market consensus and imminent resolutions.
Requirements
A remote streamable HTTP endpoint; nothing to install locally. No API key or account is declared. Paid tools cost $0.001 per call via x402, settled in USDC on Base, so a funded wallet capable of x402 payments is needed. Network access to the endpoint is required.
Before you install
Most tools are paid at $0.001 per call in USDC on Base, so repeated use spends real money from a wallet; the free service_info tool should be checked first. Data is aggregated with roughly 15-second freshness and confidence scores, so it may lag or differ from exchange feeds. No credentials are declared, but x402 payment handling involves a wallet.

Installation

In SourceWeft

  1. Open chainpulse — real-time crypto + prediction market data for AI agents 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/in.fastdb.md%2Fchainpulse/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
