Fresh RAG context for AI agents — updated Mon/Wed/Fri.
AgentDB is a curated knowledge base your agent queries at inference time. 40 sources — AI/tech, startups, alternative markets, and emerging economies — scraped, AI-summarised, and structured into agent-ready JSON.
Connect it to Claude Desktop, Cursor, or any MCP-compatible agent in under 2 minutes.
Agents need current information at inference time, but raw sources are expensive context. A podcast transcript is ~2,400 tokens; the AgentDB version of the same item is ~160 tokens — a structured summary with key points, tags, and a confidence score. Same signal, ~15× less context.

Cost to run: ~£2–3/month (DeepSeek API calls only — everything else is free tier).
The AgentDB MCP server gives your agent two tools: get_latest_knowledge and search_knowledge.
Install uv — it handles Python automatically:
curl -LsSf https://astral.sh/uv/install.sh | shAdd to ~/Library/Application Support/Claude/claude_desktop_config.json:
{
"mcpServers": {
