A month ago, @tan_stack joined AG-UI 🏝️ That means if you have: TanStack frontend → Point at any AG-UI agent TanStack AI→ Any AG-UI client can consume it One wire format does the talking bidirectionally. copilotkit.ai/ag-ui

Live proof: in the AG-UI dojo, ask "weather in San Francisco" against a Mastra agent. Then swap to LangGraph. Same events and UI, zero frontend changes. AG-UI gives you drop-in replacement. Streaming, generative UI, tool calls, approval flows, shared state — all standardized

Our MCP server is free and has no limits. Most MCP servers cap you because they're maintaining docs for thousands of libraries. That's expensive. We only maintain ours. So we indexed everything -- GitHub repos, Discord threads, Slack conversations, Notion pages, PDFs. Ask

Your agent gets: - semantic search over everything you indexed - a virtual filesystem to grep, cat, and explore your files - Q&A pulled from Slack and Discord conversations

Two commands to run it: - npx @copilotkit/pathfinder init - npx @copilotkit/pathfinder serve One config file handles your sources, embeddings, and tools. No external API key needed if you run embeddings locally.

It's a self-hosted knowledge server for AI agents. Point it at your docs, code, Notion pages, Slack threads, and Discord forums. It indexes everything into searchable knowledge your agent can actually use.

The engine behind it is open source. It's called Pathfinder. Here's what it does 👇
