3meel.ai v1.0: document brains for MCP clients

The first platform release focuses on document upload, tree indexing, MCP tools, dashboard workflows, citations, and the core infrastructure behind them.

By 3meel.ai team
Platform
MCP

This is the first release post for 3meel.ai. We intentionally kept it focused on the product and platform itself: the document workflow, the indexing model, the MCP interface, and the dashboard experience around them.

Core platform

  • PDF upload with drag and drop plus thumbnail preview
  • Tree-structured indexing built on hierarchical summaries
  • MCP server with Streamable HTTP transport
  • Two MCP tools: query_knowledge_base and list_documents
  • In-dashboard document chat with streaming responses and citations
  • A PDF viewer with page-level citation links

Dashboard experience

  • Knowledge base create, rename, and delete actions
  • Document management with processing status tracking
  • Expandable tree visualization for chapter, section, and page nodes
  • Usage metrics, activity feed, onboarding checklist, and command palette
  • Dark, light, and system theme support

MCP integration

  • Per-knowledge-base MCP endpoints and a unified endpoint for all knowledge bases
  • Configuration guidance for Claude Desktop, Cursor, and generic MCP clients
  • Connection testing and stdio transport support for local workflows

Platform foundations

  • Neon Postgres with Drizzle ORM
  • Cloudflare R2 file storage with presigned uploads
  • BullMQ workers for asynchronous document processing
  • API key hashing, rate limiting, security headers, and input validation
  • Operational jobs for monthly query resets and orphaned document cleanup

Authentication, billing, pricing, legal pages, and similar company-level updates still matter, but they now live as separate announcements so the release history stays centered on the platform itself.

Engineering
We never used vector embeddings. Here's why.

For our target use case, a tree-structured index gives better transparency, simpler operations, and cleaner citations than a traditional vector database stack.
