Voidfeed

What is Voidfeed?

Voidfeed is an MCP server that connects AI agents to Voidfeed’s structured knowledge engineered for machine consumption. It works with Claude Desktop, Cursor, Windsurf, and any Model Context Protocol–compatible runtime.

How to use Voidfeed?

Install via npx voidfeed-mcp or npm install -g voidfeed-mcp. Add the server configuration to your MCP client’s JSON settings (e.g., under mcpServers.voidfeed). Optionally set the VOIDFEED_JWT environment variable for paid-tier access. Use any of the listed tools, such as voidfeed_catalog or voidfeed_semantic_search.

Key features of Voidfeed

• Authority content — source-verified reference data
• Agent directory — 523 agents with cost, orchestration roles, and failure modes
• Model benchmarks — 247 model×benchmark combinations with confidence intervals
• Semantic search across all content types

Use cases of Voidfeed

• Connect AI agents to structured, machine‑curated knowledge for reasoning
• Browse and compare AI models using benchmark data

FAQ from Voidfeed

What is the difference between the free Surface tier and The Void tier?

The Surface tier is free, requires no authentication, and provides limited depth (e.g., 5 results in semantic search, 8 benchmark entries). The Void tier unlocks full depth and additional tools like voidfeed_void_pulse; access is obtained by paying 100,000 sats/30 days (or via Stripe or USDC on Base) and setting a JWT.

How do I get a JWT for The Void tier?

Run the voidfeed_enter_void tool to receive a Lightning invoice. Pay the invoice (100,000 sats for 30 days) and receive a JWT. Set the JWT in the VOIDFEED_JWT environment variable when configuring the server.

Which tools are available for free?

Free tools include voidfeed_catalog, voidfeed_inventory, voidfeed_get_content (surface depth), voidfeed_semantic_search (5 results), voidfeed_agent_directory (5 agents), voidfeed_benchmark_lookup (8 entries), voidfeed_model_compare, and voidfeed_enter_void.

Which runtimes are supported?

Voidfeed works with Claude Desktop, Cursor, Windsurf, and any MCP‑compatible runtime.

What environment variables does Voidfeed use?

VOIDFEED_JWT (optional, for The Void tier) and VOIDFEED_BASE_URL (optional, default https://voidfeed.ai) to override the API base URL.
