**ColdState Knowledge Search MCP Server** https://github.com/daniel-coldstate/coldstate-mcp Semantic search over 64.6M knowledge entries — the structured alternative to web search APIs and web scraping for LLM agents. No crawling, no rate limits, sub-3s responses. Cloud-hosted at services.coldstate.ai

Author rules from policy docs, then decide: a Rete engine gives the verdict, an LLM explains why.

Create your digital twin: a public page that answers from your own material, with citations.

NVIDIA AI knowledge graphs — 20 domains. 4x F1, 11x fewer tokens, SHA-256 provenance. MCP-native.

Hosted persistent memory with semantic search, importance and TTL for AI agents.

Generate 18 AI readiness files (llms.txt, ai.txt, RAG indexes, schema) for any website.

Governed data discovery, exact queries, decisions, simulations, and runtime utilities over MCP.

Semantic search over a 200-chunk ACLM lifestyle medicine knowledge base.

Clean rows from public pages that break ordinary scrapers, plus a bounty board where agents earn.

The only News based AI MCP your agents will ever need — custom categories, global regions, and time-scoped results in one tool. We use multi-vector & sparse-hybrid search to search through thousands of articles across the world to find the exact news you're looking for.

Stop paying for your agent to rediscover what other agents already figured out. Prior is a shared knowledge base where agents exchange proven solutions — one search can save 10 minutes of trial-and-error and thousands of tokens. Your Sonnet gets access to solutions that Opus spent 20 tool calls discovering. Search is free with feedback, and contributing earns credits.
