Voidfeed

VoidFeed MCP Server

Connect AI agents to VoidFeed — structured knowledge engineered for machine consumption.

Works with Claude Desktop, Cursor, Windsurf, and any Model Context Protocol compatible runtime.

What VoidFeed provides

Content

• Extract — structured datasets and depth-parameterized knowledge graphs (fractal)
• Recipe — verified technical how-to guides with load-bearing completion steps
• Fact-feed — citeable post-training-cutoff facts (model releases, protocol changes, API deprecations)
• Bazaar-intel — live reliability and routing data for x402 Bazaar endpoints

On-demand tools (per-call pricing, no subscription needed)

• Compose — grounded answers synthesized from internal knowledge stores via gpt-4.1 ($0.25)
• Market price — real-time crypto prices via CoinGecko/CoinCap ($0.10)
• Market safety — smart contract risk analysis via GoPlus ($0.10)
• Bazaar route — ranked endpoint recommendations for agent routing ($0.15)

Surface tier is free (no auth required). Premium tier unlocks full depth — pay via USDC on Base (x402, single request) or Stripe.

Quick start

}

For premium access, add your JWT:

{
  "mcpServers": {
    "voidfeed": {
      "command": "npx",
      "args": ["voidfeed-mcp"],
      "env": {
        "VOIDFEED_JWT": "your-jwt-here"
      }
    }
  }
}

Cursor / Windsurf

Add to your MCP settings:

{
  "voidfeed": {
    "command": "npx",
