Overview

AI-generated overview

A remote MCP server that returns aggregated crypto news with sentiment scores and token mentions, paid per call via x402 in USDC.

What you can do
Fetch the latest crypto news headlines, optionally limited in count or filtered by token symbol such as BTC or ETH, with no signup or API key required.
When to use it
Useful when an assistant needs current crypto headlines, market sentiment, or news-driven context for trading analysis, rather than price data, historical candles, funding rates or whale tracking.
Requirements
A remote SSE endpoint; no account, API key or environment variables are declared. Each call is paid in USDC on the Base L2 network through the x402 protocol, so an x402-aware client with a funded wallet is needed.
Before you install
Every call costs money (listed at $0.005 per news request) and is settled in USDC on Base, so a wallet and spending limits matter. News is aggregated from third-party sources and sent to the remote service; sentiment scores are informational, not advice.

Installation

In SourceWeft

  1. Open Crypto News Feed API 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.Br0ski777%2Fcrypto-news/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

Other MCP clients

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
