> 🎙️ **AI-Powered Meeting Intelligence for Claude Desktop**

An experimental [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) server that bridges [Granola.ai](https://granola.ai/) meeting intelligence with Claude Desktop. Access your meeting transcripts, notes, and insights directly through natural language conversations.

## ✨ Features

- **🔍 Meeting Search** — Search meetings by title, content, participants, and transcript content
- **📋 Meeting Details** — Get comprehensive meeting metadata with local timezone display
- **📝 Full Transcript Access** — Retrieve complete meeting conversations with speaker identification
- **📄 Rich Document Content** — Access actual meeting notes, summaries, and structured content
- **📊 Pattern Analysis** — Analyze patterns across meetings (participants, frequency, topics)
- **🌍 Timezone Intelligence** — All timestamps automatically display in your local timezone
- **🔒 100% Local Processing** — No external API calls; all data stays on your machine

## 🛠️ Tech Stack

| Component | Technology |
|-----------|------------|
| **Language** | Python 3.12+ |
| **MCP SDK** | `mcp>=1.0.0` |
| **Data Validation** | Pydantic 2.x |
| **Package Manager** | uv (recommended) or pip |
| **Build System** | Hatchling |
| **Release Automation** | python-semantic-release |

## 📦 Installation

### Prerequisites
- [uv](https://docs.astral.sh/uv/) package manager
- macOS with Granola.ai installed

### Claude Desktop

Add to your `claude_desktop_config.json`:

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

```json
{
  "mcpServers": {
    "granola": {
      "command": "uvx",
      "args": ["granola-mcp-server"]
    }
  }
}
```

Then restart Claude Desktop.

### Claude Code

```bash
claude mcp add granola -- uvx granola-mcp-server
```

### Cursor

[![Add Granola MCP to Cursor](https://cursor.com/deeplink/mcp-install-dark.svg)](https://cursor.com/en-US/install-mcp?name=granola&config=eyJjb21tYW5kIjoidXZ4IiwiYXJncyI6WyJncmFub2xhLW1jcC1zZXJ2ZXIiXSwiZW52Ijp7fX0=)

### Updating

`uvx` caches the package after first run. To update to the latest version:

```bash
uvx --refresh granola-mcp-server
```

Then restart your MCP client.

### Manual installation (alternative)

If you prefer to install from source:

```bash
cd ~
git clone https://github.com/proofgeist/granola-mcp-server
cd granola-mcp-server
uv sync
```

Then configure your MCP client to run the server directly:

```json
{
  "mcpServers": {
    "granola": {
      "command": "uv",
      "args": ["--directory", "/Users/YOUR_USERNAME/granola-mcp-server", "run", "granola-mcp-server"]
    }
  }
}
```

To update a source install: `git pull && uv sync`

### pip (alternative)

```bash
pip install granola-mcp-server
```

Then configure your MCP client to run `granola-mcp-server`.

### Environment Variables

| Variable | Description | Default |
|----------|-------------|---------|
| `GRANOLA_PARSE_PANELS` | Enable parsing of document panels for rich notes | `1` (enabled) |
| `TZ` | Override local timezone detection | Auto-detected |

Set `GRANOLA_PARSE_PANELS=0` to disable document panel parsing if you encounter issues.

## 🚀 Usage

Once configured, restart Claude Desktop and start interacting with your Granola meetings using natural language:

### Search & Discovery

- *"Search for meetings about quarterly planning"*
- *"Show me yesterday's meetings"*
- *"Find meetings with David from this week"*
- *"List all my recent standup meetings"*

### Transcript Access

- *"Get the transcript from yesterday's IA meeting"*
- *"What was discussed in the Float rollback planning meeting?"*
- *"Show me the full conversation from the David Tanner meeting"*

### Content Analysis

- *"Analyze participant patterns from last month"*
- *"What documents are associated with the product review meeting?"*
- *"Search for mentions of 'schema labeling' in meeting transcripts"*

### Available Tools

| Tool | Description | Parameters |
|------|-------------|------------|
| `search_meetings` | Search meetings by title, content, participants | `query` (string), `limit` (int, optional) |
| `get_meeting_details` | Get detailed information about a meeting | `meeting_id` (string) |
| `get_meeting_transcript` | Get full transcript with speaker identification | `meeting_id` (string) |
| `get_meeting_documents` | Get documents and notes associated with a meeting | `meeting_id` (string) |
| `analyze_meeting_patterns` | Analyze patterns across meetings | `pattern_type` (enum: topics/participants/frequency), `date_range` (optional) |

## 🧪 Development

### Running Tests

```bash
# Run panel parsing test
uv run python test_server.py

# Test with real cache file
uv run python test_real_cache.py
```

### Running the Server Directly

```bash
uv run granola-mcp-server
```

Or using the run script:

```bash
uv run python run_server.py
```

## 🔒 Security & Privacy

| Feature | Status |
|---------|--------|
| **100% Local Processing** | ✅ All data stays on your machine |
| **No External API Calls** | ✅ No data sent to external services |
| **Granola Permissions Respected** | ✅ Uses existing Granola.ai access controls |
| **Read-Only Access** | ✅ Server only reads from Granola's cache |

## 📊 Performance

- **Fast Loading**: Sub-2 second cache loading for hundreds of meetings
- **Rich Content**: Extracts 25,000+ character transcripts and meeting notes
- **Efficient Search**: Multi-field search across titles, content, participants, and transcripts
- **Memory Optimized**: Lazy loading with intelligent content parsing
- **Production Ready**: Successfully processes real Granola data (11.7MB cache files)
- **Scalable**: Handles large datasets with 500+ transcript segments per meeting

## 🐛 Troubleshooting

### Common Issues

**"Cache file not found"**
```bash
# Ensure Granola.ai is installed and has processed some meetings
ls -la ~/Library/Application\ Support/Granola/cache-v*.json
```

**"uv command not found"**
```bash
# Install uv
curl -LsSf https://astral.sh/uv/install.sh | sh
```

**Server not appearing in Claude Desktop**
- Check Claude Desktop logs: `~/Library/Logs/Claude/mcp-server-granola.log`
- Restart Claude Desktop after config changes

**Meeting notes appear empty**
- Granola sometimes stores rich notes inside `documentPanels` rather than `notes_plain`
- This server reads those panels by default; set `GRANOLA_PARSE_PANELS=0` to disable

### Manual installation issues

These apply only if you installed from source (git clone) rather than via `uvx`.

**"Permission denied" or "Operation not permitted"**
- This happens when the server is installed in `~/Documents` or other protected macOS folders
- Move the installation to your home directory:
  ```bash
  mv ~/Documents/granola-mcp-server ~/granola-mcp-server
  cd ~/granola-mcp-server
  uv sync
  ```
  Then update the path in `claude_desktop_config.json`
- Or grant Claude Desktop Full Disk Access in System Settings > Privacy & Security

**"Current directory does not exist"**
- This error occurs when using `uv run` with the `--directory` flag
- Ensure the path in your Claude config points to the actual clone location

**"Failed to spawn process" or "No such file or directory"**
- Run `uv sync` in the project directory to rebuild the venv
- Verify the script exists: `ls -la ~/granola-mcp-server/.venv/bin/granola-mcp-server`
