What this connector unlocks

Connect your AI workflows to FastGPT, the powerful open-source platform for building knowledge-based AI applications. This MCP provides 12 tools for full lifecycle management of datasets, apps, and RAG (Retrieval-Augmented Generation) pipelines.

What you can do

  • Dataset Orchestration — Create, list, and manage knowledge base datasets with granular control over configurations
  • Document Ingestion — Push text content or chunks directly to datasets for automatic indexing and vectorization
  • Semantic Search — Run advanced semantic queries against your knowledge bases to test relevance and RAG quality
  • Application Management — List and inspect AI applications to monitor their configurations and linked datasets
  • OpenAI-Compatible Chat — Trigger RAG-powered chat completions with full context, session tracking, and intermediate step visibility

How it works

1. Subscribe to this server
2. Set up [FastGPT](https://fastgpt.in/) (cloud or self-hosted)
3. Navigate to your App settings and enter the API Access section
4. Generate an API Key
5. Identify your Base URL (e.g., https://api.fastgpt.in for cloud)
6. Insert both into the fields below to start managing your RAG pipelines.

Who is this for?

  • Knowledge Engineers — automate the ingestion of documentation across multiple datasets
  • RAG Developers — debug semantic search results and optimize chunking strategies programmatically
  • System Integrators — build complex AI workflows that require dynamic knowledge base management
