Features multi-engine research across 9+ search backends with semantic similarity ranking, and requires no API keys. - [Features](#features) - [Multi-Engine Deep Research](#multi-engine-deep-research) - [Installation](#installation) - [Run Directly via `uvx`](#run-directly-via-uvx) - [Using Docker (recommended)](#using-docker-recommended) - [Agent Skills](#agent-skills) - [Security audits](#security-audits) - [MCP Clients](#mcp-clients) - [Examples on Claude Desktop](#examples-on-claude-desktop) - [Result](#result) - [Contributing](#contributing) - [License](#license) ```mermaid %%{init: {'theme': 'base'}}%% flowchart TD A[User] -->|1.Submits LLM Query| B[Language Model] B -->|2.Sends Query| C[mcp-local-rag Tool] subgraph mcp-local-rag Processing C -->|Search DuckDuckGo| D[Fetch 10 search results] D -->|Fetch Embeddings| E[Embeddings from Google's MediaPipe Text Embedder] E -->|Compute Similarity| F[Rank Entries Against Query] F -->|Select top k results| G[Context Extraction from URL] end G -->|Returns Markdown from HTML content| B B -->|3.Generated response with context| H[Final LLM Output] H -->|5.Present result to user| A classDef default stroke:#333,stroke-width:2px; classDef process stroke:#333,stroke-width:2px; classDef input stroke:#333,stroke-width:2px; classDef output stroke:#333,stroke-width:2px; class A input; class B,C process; class G output; ``` # Features ## Multi-Engine Deep Research The server supports comprehensive multi-engine research capabilities that go beyond simple single-query searches: - **9+ Search Backends**: DuckDuckGo, Google, Bing, Brave, Wikipedia, Yahoo, Yandex, Mojeek, Grokipedia - **Multi-Topic Research**: Search multiple related queries simultaneously - **Semantic Ranking**: RAG-like similarity scoring ranks the most relevant results - **Privacy Options**: Choose privacy-focused engines (DuckDuckGo, Brave) or comprehensive ones (Google) - **No API Keys Required**: All processing runs locally with embedded models ### Deep Research Tools 1. **`deep_research`** - Comprehensive multi-engine research - Search across multiple engines simultaneously - Ideal for complex topics requiring diverse perspectives - Customizable backends and result limits 2. **`deep_research_google`** - Google-focused deep dive - Leverage Google's comprehensive index - Best for technical/scientific queries 3. **`deep_research_ddgs`** - Privacy-first deep research - Use DuckDuckGo for private, extensive research - Great for general topics without tracking 4. **`rag_search_ddgs`** & **`rag_search_google`** - Quick single searches - Fast, focused searches when you need quick answers # Installation Locate your MCP config path [here](https://modelcontextprotocol.io/quickstart/user) or check your MCP client settings. ### Run Directly via `uvx` This is the easiest and quickest method. You need to install [uv](https://docs.astral.sh/uv/) for this to work.
Add this to your MCP server configuration: ```json { "mcpServers": { "mcp-local-rag":{ "command": "uvx", "args": [ "--python=3.10", "--from", "git+https://github.com/nkapila6/mcp-local-rag", "mcp-local-rag" ] } } } ``` ### Using Docker (recommended) Ensure you have [Docker](https://www.docker.com) installed.
Add this to your MCP server configuration: ```json { "mcpServers": { "mcp-local-rag": { "command": "docker", "args": [ "run", "--rm", "-i", "--init", "-e", "DOCKER_CONTAINER=true", "ghcr.io/nkapila6/mcp-local-rag:v1.0.2" ] } } } ``` # Agent Skills This repository includes **Agent Skills** that teach Claude how to effectively use the mcp-local-rag tools for intelligent web searches and deep research. Skills are folders of instructions that Claude loads dynamically to improve performance on specialized tasks. ### Available Skills **`local-rag-search`** - Teaches Claude best practices for: - **Smart tool selection**: Choosing between quick searches or comprehensive deep research - **Multi-engine research**: Using multiple search backends for diverse perspectives - **Effective query formulation**: Writing natural language queries that yield better results - **Parameter tuning**: Adjusting `num_results`, `top_k`, and backend selection for different use cases - **Privacy-aware searching**: Defaulting to privacy-focused engines while allowing comprehensive searches when needed ### Deep Research Use Cases The skill enables comprehensive topic research using multiple search terms and engines. It's particularly useful for technical deep dives that leverage Google's documentation coverage, multi-perspective analysis that compares information across different search engines, privacy-focused research using DuckDuckGo or Brave, and factual verification by cross-referencing Wikipedia and other authoritative sources. ### Using the Skills **In Claude Desktop:** 1. Go to **Settings** → **Skills** 2. Click **Add Skill** → **Add from folder** 3. Select `skills/local-rag-search/` **In conversations:** Once loaded, simply ask Claude to search for information and it will automatically apply the skill's best practices. Try queries like: - "Do deep research on recent quantum computing developments" - "Search multiple sources for sustainable energy solutions" - "Find comprehensive technical documentation about Kubernetes optimization" Learn more about Agent Skills at the [Anthropic Skills Repository](https://github.com/anthropics/skills). See the [skills/README.md](skills/README.md) for detailed usage instructions and skill development guidelines. # Security audits MseeP does security audits on every MCP server, you can see the security audit of this MCP server by clicking [here](https://mseep.ai/app/nkapila6-mcp-local-rag).

# MCP Clients The MCP server should work with any MCP client that supports tool calling. Has been tested on the below clients. - Claude Desktop - Cursor - Goose - Others? You try! # Examples on Claude Desktop When an LLM (like Claude) is asked a question requiring recent web information, it will trigger `mcp-local-rag`. When asked to fetch/lookup/search the web, the model prompts you to use MCP server for the chat. In the example, have asked it about Google's latest Gemma models released yesterday. This is new info that Claude is not aware about.

## Result `mcp-local-rag` performs a live web search, extracts context, and sends it back to the model—giving it fresh knowledge:

## Buy Me A Coffee If the software I've built has been helpful to you. Please do buy me a coffee, would really appreciate it! 😄 [![ko-fi](https://ko-fi.com/img/githubbutton_sm.svg)](https://ko-fi.com/X8X51MK4A1) # Contributing Have ideas or want to improve this project?
