Overview

PipesHub indexes Slack, Google Drive, GitHub, Microsoft 365, Notion and 50+ systems into a knowledge graph (Neo4j or ArangoDB), Qdrant and MongoDB, then serves permission-aware search with block-level citations and hands the same context to agents over MCP and SDKs. Access is checked against source permissions at query time. A one-command installer writes Compose files and starts the stack on port 3000.

Who it is for: companies wanting cited answers across internal tools

Strengths

  • Permission filtering resolved against the source system at query time
  • 50+ connectors with real-time and scheduled indexing
  • MCP server plus Python, TypeScript and Go SDKs
  • Kubernetes deployment with HA defaults; slim or full Compose profiles

Weaknesses

  • Needs Neo4j or ArangoDB, Qdrant, MongoDB, Redis, and Kafka at scale
  • Installer is curl piped to bash
  • Audio and video are stored but not indexed yet
  • Plain-HTTP cloud deployments show a white screen; TLS termination required

What it needs

  • no GPU
  • Docker + Compose
  • Needs Neo4j or ArangoDB, Qdrant, MongoDB, Redis, Kafka (larger deployments)
  • Models: any LLM provider, bring your own model, Ollama, local embedding server by default
  • port 3000
