WireSaber

Newswire for AI agents — A Claude-native MCP tool providing structured news/event feed

WireSaber is an MCP (Model Context Protocol) server that exposes a structured news API optimized for AI agents, not humans. It returns machine-readable news events with entities, topics, and relevance scores — perfect for Claude code agents that need fresh, reliable external signals.

🎯 Use Case

When building Claude code agents, you often need external signals:

• "What's new in AI funding this week?"
• "Any major acquisitions in the startup space?"
• "Latest developments in LLM research"

WireSaber provides structured JSON responses with entities already extracted, topics tagged, and relevance scores computed — no web scraping or parsing required.

📦 Installation

Option 1: Clone & Build (Recommended)

# Clone the repository
git clone https://github.com/luke-song/wiresaber.git
cd wiresaber

# Install dependencies
pnpm install

# Build the project
pnpm build

Option 2: NPM Install

npm install -g wiresaber

Then update your .mcp.json:

{
  "mcpServers": {
    "agentwire": {
      "command": "agentwire",
      "env": {
        "AGENTWIRE_USE_REAL_NEWS": "true"
      }
    }
  }
}

Option 3: Remote (no install)

WireSaber also runs as a hosted MCP server over Streamable HTTP — point a client directly at it, no clone/build required:

{
  "mcpServers": {
    "wiresaber": {
      "type": "http",
      "url": "https://wiresaber.vercel.app/api/mcp"
    }
  }
}

The remote endpoint is stateless (each request gets a fresh session) and always uses live RSS data.

Register with Claude Code

Add to your project's .mcp.json (recommended for per-project setup):

{
  "mcpServers": {
    "agentwire": {
      "command": "node",
      "args": ["/absolute/path/to/wiresaber/dist/index.js"],
      "env": {
        "AGENTWIRE_USE_REAL_NEWS": "true"
      }
    }
  }
}

Or add to ~/.claude/settings.json for global access:

{
  "mcpServers": {
    "agentwire": {
      "command": "node",
      "args": ["/absolute/path/to/wiresaber/dist/index.js"],
      "env": {
        "AGENTWIRE_USE_REAL_NEWS": "true"
      }
    }
  }
}

Important: Replace /absolute/path/to/wiresaber with your actual path (run pwd in the wiresaber directory to see it).

Note: Set AGENTWIRE_USE_REAL_NEWS to "true" for live RSS feeds, or omit for mock data.
