>_ 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 (BTC, markets, earthquakes, news, prediction markets). 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, 30+ REST endpoints. BTC + crypto, stocks, prediction markets, earthquakes, weather, status, GitHub, HuggingFace, Solana, 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 APIs require key registration even for read-only data. 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. APIs that take a curl command, no auth dance. An MCP server you point Claude at in one config block. Articles that show real code. Recipes you can copy-paste. 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 recipe that would help your daily work, the issue tracker is at github.com/RipperMercs/terminalfeed. PRs welcome.
