shinpr/mcp-local-rag — Local-first RAG server for developers.

Description and use

**Brief Summary**
shinpr/mcp‑local‑rag is a TypeScript‑based, zero‑setup server that brings local‑first Retrieval‑Augmented Generation to developers. It combines semantic and keyword search over source code and technical documentation, exposing a simple API/CLI that can be used from MCP or directly from the command line, keeping all data private.

**Value**

• **Turn isolated prompts into repeatable workflows** – By providing a private, self‑hosted RAG layer, developers can embed code‑aware search into any LLM‑driven agent, turning ad‑hoc queries into deterministic, version‑controlled pipelines.
• **Unified multi‑agent orchestration** – The service can be called from multiple agents, allowing them to share a common knowledge base, coordinate tool use, and maintain a consistent “memory” of code artifacts.
• **Full control & privacy** – Because the index lives on the developer’s machine or on‑prem infrastructure, no proprietary code ever leaves the organization, satisfying security and compliance requirements.

**Practical Adoption Path**

1. **Spin‑up** – Clone the repo and run npm install && npm start (or use the provided Docker image). No external services or cloud credentials are needed.
2. **Ingest** – Point the CLI to the codebase and documentation directories; the server builds a hybrid vector + inverted index automatically.
3. **Integrate** – Call the REST endpoints or use the generated TypeScript SDK from your MCP pipelines or any Node.js project. Existing agents can replace their ad‑hoc search calls with a single request to /search.
4. **Iterate** – Adjust indexing parameters (embedding model, keyword tokenizer) via the config file, then redeploy with zero downtime.

**Production Readiness**

• **Activity & community** – 254 ★, 49 forks, recent commits (last updated 2026‑05‑11) and a healthy issue/PR flow indicate an active maintainer base.
• **Stability** – The project follows semantic‑versioning, ships pre‑built Docker images, and provides both API and CLI entry points, making CI/CD integration straightforward.
• **Security & compliance** – All processing is local; the only external dependency is the embedding model (which can be swapped for an on‑prem model). No known licensing or supply‑chain issues have been flagged, though a final legal review is recommended.

Overall, shinpr/mcp‑local‑rag is a mature, low‑friction OSS component that can be piloted quickly and scaled to production for any organization that needs private, code‑centric RAG capabilities within multi‑agent workflows.

Problem

shinpr/mcp-local-rag helps turn isolated prompts and tools into repeatable agent workflows.

Outcome

High for an OSS candidate: recent activity, adoption, and ecosystem signals are strong enough for a serious pilot.

Workflow

• coordinate multi-agent workflows
• add tool-use pipelines
• standardize agent memory

Evidence

Local-first RAG server for developers. Semantic + keyword search for code and technical docs. Works with MCP or CLI. Fully private, zero setup.
