Goldie 🐕

A Retrieval-Augmented Generation (RAG) MCP server written in Go that runs locally in your machine.

Features

Multiple embedding backends: Choose between MiniLM (local, via ONNX Runtime) or Ollama
Local embeddings: Uses [all-MiniLM-L6-v2] model for high-quality semantic embeddings (384 dimensions)
Ollama support: Use any Ollama embedding model (nomic-embed-text, mxbai-embed-large, etc.)
SQLite vector storage: Persistent storage using sqlite-vec extension
Document chunking: Automatically chunks large documents with overlap
Semantic search: Find relevant documents using vector similarity
Directory indexing: Batch index files with glob patterns, supports recursive search

Requirements

Ollama Backend

If you want to use Ollama instead of MiniLM, you only need Ollama installed:

# macOS
brew install ollama

# Linux
curl -fsSL https://ollama.com/install.sh | sh

# Pull an embedding model
ollama pull nomic-embed-text

Skip the ONNX Runtime installation below if you only plan to use Ollama.

MiniLM Backend (requires ONNX Runtime)

# macOS
brew install onnxruntime

# Ubuntu/Debian
sudo apt install libonnxruntime-dev

# Fedora/RHEL
sudo dnf install onnxruntime-devel

# Arch Linux
sudo pacman -S onnxruntime

Installation

From Releases (recommended)

Download a pre-built binary from the releases page:

| Platform | Binary | |----------|--------| | macOS (Apple Silicon) | goldie-mcp-darwin-arm64 | | macOS (Intel) | goldie-mcp-darwin-amd64 | | Linux (x86_64) | goldie-mcp-linux-amd64 | | Linux (ARM64) | goldie-mcp-linux-arm64 |

# Example for macOS Apple Silicon
curl -LO https://github.com/srfrog/goldie-mcp/releases/latest/download/goldie-mcp-darwin-arm64
chmod +x goldie-mcp-darwin-arm64
mv goldie-mcp-darwin-arm64 ~/bin/goldie-mcp

The release binaries are ad-hoc codesigned for macOS and include the MiniLM model, so no additional downloads are required.

Build from Source

Requires Go 1.22+, CGO enabled, and Git LFS (the model file is stored with LFS):

git lfs install  # if not already configured
git clone https://github.com/srfrog/goldie-mcp
cd goldie-mcp
make build

Usage with Claude Code

With MiniLM (default)

claude mcp add -s user -e GOLDIE_DB_PATH=~/.local/share/goldie/index.db goldie /path/to/goldie-mcp

Or add to ~/.claude.json:

{
  "mcpServers": {
    "goldie": {
      "type": "stdio",
      "command": "/path/to/goldie-mcp",
      "env": {
        "GOLDIE_DB_PATH": "/home/user/.local/share/goldie/index.db",
        "ONNXRUNTIME_LIB_PATH": "/path/to/libonnxruntime.so"
      }
    }
  }
}

Note: ONNXRUNTIME_LIB_PATH is optional if the library is in a standard location.

With Ollama

claude mcp add -s user -e GOLDIE_DB_PATH=~/.local/share/goldie/index.db goldie /path/to/goldie-mcp -- -b ollama

Or add to ~/.claude.json:

{
  "mcpServers": {
    "goldie": {
      "type": "stdio",
      "command": "/path/to/goldie-mcp",
      "args": ["-b", "ollama"],
      "env": {
        "GOLDIE_DB_PATH": "/home/user/.local/share/goldie/index.db",
        "OLLAMA_HOST": "http://localhost:11434",
        "OLLAMA_EMBED_MODEL": "nomic-embed-text"
      }
    }
  }
}

Note: Make sure Ollama is running (ollama serve) before starting Claude Code.

Usage with Claude Desktop

Add to your Claude Desktop configuration (claude_desktop_config.json):

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

With MiniLM (default)

{
  "mcpServers": {
    "goldie": {
      "type": "stdio",
      "command": "/path/to/goldie-mcp",
      "env": {
        "GOLDIE_DB_PATH": "/home/user/.local/share/goldie/index.db"
      }
    }
  }
}

With Ollama

{
  "mcpServers": {
    "goldie": {
      "type": "stdio",
      "command": "/path/to/goldie-mcp",
      "args": ["-b", "ollama"],
      "env": {
        "GOLDIE_DB_PATH": "/home/user/.local/share/goldie/index.db",
        "OLLAMA_EMBED_MODEL": "nomic-embed-text"
      }
    }
  }
}

Usage with OpenAI Codex

Add to your Codex configuration (~/.codex/config.toml):

With MiniLM (default)

[mcp_servers.goldie]
command = "/path/to/goldie-mcp"

[mcp_servers.goldie.env]
GOLDIE_DB_PATH = "/home/user/.local/share/goldie/index.db"
ONNXRUNTIME_LIB_PATH = "/path/to/libonnxruntime.so"

Note: ONNXRUNTIME_LIB_PATH is optional if the library is in a standard location. Homebrew will install it to /opt/homebrew/lib/libonnxruntime.dylib on macOS. In Linux, find it with ldconfig -p | grep onnxruntime.

With Ollama

[mcp_servers.goldie]
command = "/path/to/goldie-mcp"
args = ["-b", "ollama"]

[mcp_servers.goldie.env]
GOLDIE_DB_PATH = "/home/user/.local/share/goldie/index.db"
OLLAMA_EMBED_MODEL = "nomic-embed-text"

Available Tools

index_content

Index text content for semantic search. Use this for web pages, API responses, notes, or any text that doesn't come from a local file. For local files, use index_file instead.

Parameters:

content (required): The text content to index
metadata (optional): JSON string with metadata (e.g., {"source": "https://example.com", "title": "Page Title"})

index_file

Index a file from the filesystem.

Parameters:

path (required): Path to the file to index

index_directory

Index all files matching a pattern in a directory.

Parameters:

directory (required): The directory path to index
pattern (optional): File pattern to match (e.g., *.md, *.txt). Default: *
recursive (optional): Whether to search subdirectories. Default: false

search_index

Search for documents using semantic similarity.

Parameters:

query (required): Search query text
limit (optional): Maximum results (default: 5)

recall

Recall knowledge from indexed documents about a topic. Returns a consolidated summary with source attribution, designed for natural conversation flow.

Parameters:

topic (required): The topic to recall information about
depth (optional): How many sources to consult (default: 5, max: 20)

delete_document

Delete a document from the index.

Parameters:

id (required): Document ID

count_documents

Get the total number of indexed documents.

Skip Patterns

When indexing directories, Goldie automatically skips certain files and directories to avoid indexing irrelevant content.

Default Skip Patterns

If no .goldieskip file exists in the directory being indexed, Goldie uses these defaults:

| Pattern | Description | |---------|-------------| | .[!.]* | All dotfiles and dotdirs (.git/, .env, .vscode/, etc.) | | node_modules/ | Node.js dependencies | | vendor/ | Go/PHP vendor directories | | __pycache__/ | Python bytecode cache | | AGENTS.md | AI agent configuration | | CLAUDE.md | Claude configuration |

Custom Skip Patterns

Create a .goldieskip file in the directory to define custom patterns. This replaces the defaults entirely. Same format as .gitignore, with the same pattern syntax.

# .goldieskip example
# Lines starting with # are comments

# Skip all dotfiles/dotdirs
.[!.]*

# Skip dependencies
node_modules/
vendor/
.venv/

# Skip build outputs
dist/
build/
target/

# Skip specific files
*.log
*.tmp
secrets.json

Pattern syntax:

* matches any sequence of characters
? matches any single character
[abc] matches any character in the set
[!abc] matches any character NOT in the set
Patterns ending in / match directories

Example Prompts

Here are example prompts you can use with Claude Code or Claude Desktop:

Web content:

Index this content from the React docs: "useState is a Hook that lets you add state to function components..."

API responses:

Index this API documentation: "POST /api/users - Creates a new user. Required fields: email, password"

Notes and knowledge:

Index this note: "Team decided to use PostgreSQL for the main database, Redis for caching"

With metadata:

index_file

Index the file ~/project/README.md

Index all *.txt files in ~/notes

Index all *.md files in ~/projects recursively
