Hierarchical tree index + multi-step reasoning retrieval without a vector DB. Hosted MCP with API key or App OAuth; free allowance advertised at 1000 pages with unlimited conversations for the chat path. Fits agents that blow context on long PDFs.","theCatch":"Hosted MCP needs a PageIndex API key; self-host the core repo if you refuse the cloud. Vs Supermemory / Mem0 / classic vector RAG: this is document-tree reasoning retrieval, not long-term agent memory. Free page quota is a soft ceiling — verify current Dashboard limits before treating it as unlimited corpus ingest.","verdict":"Freemium vectorless PDF RAG via MCP. Tree search over long docs; not a general agent memory store.","addedAt":"2026-09-19","featured":false,"domain":"AI Agents","subSpecialty":"Agents","subcategory":"MCP","tags":["mcp","free-tier","permissive","rag","active"],"capabilities":["mcp"],"surfaces":["MCP","Hosted"],"ecosystem":["Multi-platform"],"licenseModel":"Freemium","githubStars":402,"starsPerWeek":7,"access":"free","archived":false,"repo":{"createdAt":"2025-08-25","pushedAt":"2026-07-25","license":"MIT","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"claude-code","name":"Claude Code","tagline":"Terminal-first coding agent with deep repository context"},{"slug":"cursor","name":"Cursor","tagline":"The AI-first code editor that understands your codebase"},{"slug":"devin","name":"Devin","tagline":"Autonomous AI engineer for defined engineering tasks"},{"slug":"stagehand","name":"Stagehand","tagline":"AI-native browser automation that mixes code and natural language"},{"slug":"browser-use","name":"Browser Use","tagline":"Open-source framework for LLM-driven browser agents"}],"links":{"self":"/api/gems/pageindex-mcp","html":"/gems/pageindex-mcp","markdown":"/gems/pageindex-mcp.md","category":"/api/gems?category=agents","categoryPage":"/stacks/agents"}}
