FieldCure.Mcp.Rag 2.0.0

FieldCure.Mcp.Rag

Requires Ollama 0.4.0 or later when using Ollama for embedding or contextualization.

MCP RAG server with hybrid BM25 + vector search and AI-powered chunk contextualization — indexes documents from configured source paths, enriches chunks with AI-generated context and keywords, generates embeddings, and performs keyword (FTS5) and semantic (cosine similarity) search with Reciprocal Rank Fusion.

Install

dotnet tool install -g FieldCure.Mcp.Rag

Commands

fieldcure-mcp-rag
├── serve         --base-path <path>                         # Multi-KB MCP search server (stdio)
├── exec          --path <kb-path> [--force] [--partial ...]  # Headless indexing
├── exec-queue    --queue-file <path> [--sweep-all]           # Sequential queue orchestrator
└── prune-orphans --base-path <path>                         # Delete orphan KB folders

• serve — read-only MCP server serving all KBs under the base path. Lazy-loads per KB.
• exec — headless indexing with 2-commit model, binary-split failure isolation, deferred retry.
• exec-queue — sequential orchestrator for queued indexing requests. No GPU contention.
• prune-orphans — deletes GUID-named folders without config.json. Protects backups.

API keys are resolved from environment variables (OPENAI_API_KEY, ANTHROPIC_API_KEY, etc.).
