FEDERATED MCP NETWORK/ ONE BEARER TOKEN, TWO SERVERS, SHARED CREDIT POOL

TerminalFeed and TensorFeed.ai are sister MCP servers with a federated credit pool. Buy USDC credits on either site once and the same bearer token authenticates against both. TerminalFeed handles real-time world data (earthquakes, prediction markets, space, infrastructure status, developer activity). TensorFeed handles the AI ecosystem (model pricing, service status, latency probes, AI news, smart routing, cost projection). Most agents that want real-time context end up using both, and the federation means no second auth dance, no second wallet, no double billing.

terminalfeed.io
Real-time world data. 27 MCP tools. Prediction markets, earthquakes, climate alerts, weather, service status, GitHub, HuggingFace, Solana network, space launches, world events.
tensorfeed.ai
AI ecosystem data. 22 MCP tools. Model pricing, AI service status, latency probes, MCP registry growth, AI news (36+ sources), smart routing, cost projection, webhook watches.

Both servers are AFTA-certified: code-enforced no-charge guarantees on errors, breaker trips, schema fails, and stale data. Ed25519-signed receipts on every paid call. Public on-chain payment rail (USDC on Base). Setup snippets for both servers are on the MCP tab.

WHY THIS EXISTS/ A NOTE FROM THE TEAM

Developer tools have a marketing problem. Most landing pages for dev resources are full of stock photos, signup walls, and analytics pixels that fire before you read the headline. The good free tools are scattered across personal sites, GitHub Gists, and bookmarks shared on Hacker News. The good cheatsheets are buried under SEO-optimized rewrites of Stack Overflow.

This hub is the version we wanted to find when we were learning. Tools that load in under 200ms and don't phone home. An MCP server you point Claude at in one config block. Articles that show real code. Cheatsheets that fit on one screen. No signup, no tracking, no popup asking for your email.

If you find something broken, a tool that's missing, or a reference that would help your daily work, email hello@terminalfeed.io. Suggestions get read and usually answered within a day or two.
