idea-basin-mcp

MCP server for Idea Basin — a semantic knowledge graph with vector search, hierarchical organization, and automatic content ingestion.

Gives Claude (and any MCP-compatible AI assistant) the ability to search, browse, and save to your personal knowledge base.

How it works

flowchart LR
    subgraph client["AI Assistant"]
        Claude["Claude / Any MCP Client"]
    end

    subgraph mcp["idea-basin-mcp"]
        direction TB
        T1["search_knowledge"]
        T2["browse_nodes"]
        T3["get_node"]
        T4["save_resource"]
        T5["fetch_and_save"]
    end

    subgraph basin["Idea Basin Server :3500"]
        API["REST API"]
        Embed["Embedder"]
        Scraper["Scraper"]
    end

    subgraph storage["Storage"]
        PG[("PostgreSQL + pgvector")]
    end

    Claude -- "stdio / JSON-RPC" --> mcp
    mcp -- "HTTP" --> API
    API --> Embed
    API --> Scraper
    API --> PG
