# Debug Incident MCP Server

An MCP (Model Context Protocol) server for uploading debug incidents to Debug Memory via Cursor.

## Installation

### 1. Install the MCP Server

Clone or download this repository:

```bash
git clone https://github.com/yourusername/debug-mcp.git
cd debug-mcp
```

### 2. Install Dependencies

Using [uv](https://github.com/astral-sh/uv) (recommended):

```bash
uv sync
```

This creates a virtual environment at `.venv` and installs all dependencies.

Or using pip:

```bash
pip install .
```

### 3. Get Your API Key

1. Go to your **Debug Memory** dashboard
2. Navigate to **Settings** → **API Keys**
3. Create a new API key
4. Copy the key (starts with `dm_`)

### 4. Configure Cursor

See **[Cursor Setup Guide](cursor-setup.md)** for detailed instructions.

Quick config - create or edit `.cursor/mcp.json` in your project:

```json
{
  "mcpServers": {
    "debug-incident": {
      "command": "uv",
      "args": ["run", "debug-mcp"],
      "cwd": "C:/Users/RAS/simon_code/debug-mcp",
      "env": {
        "WORKSPACE_API_KEY": "dm_your_api_key_here"
      }
    }
  }
}
```

**⚠️ Replace:**
- `cwd` with your actual installation path
- `dm_your_api_key_here` with your API key from Debug Memory

### 5. Restart Cursor

Close and reopen Cursor for the MCP server to load.

## Usage

Once configured, the MCP server exposes these tools (see `docs/tools.md` for the full workflow and next_action behavior):

### 1) `ranked_solutions`
- Search similar incidents and return **env-aware ranked solutions**
- **Inputs**: `query_text` (required), `env` (required), `limit` (optional, default 5)
- **Output**: lookup_id, ranked solutions, recommended solution, next_action

### 2) `add_incident`
- Create a **new incident + solution + outcome** (blocks duplicates if a similar incident already exists)
- **Inputs**: `title`, `summary`, `error_signature`, `tags`, `steps`, `env`, `worked`, `notes` (optional)

### 3) `add_solution`
- Add a new fix (or env-specific variant) for an existing incident
- **Inputs**: `incident_id` (required), `steps` (required), `env` (required), `env_bucket` (optional)
- **Next action**: Record an outcome for this solution

### 4) `record_outcome`
- Record whether a solution worked or failed
- **Inputs**: `solution_id` (required), `worked` (required), `env` (required), `env_bucket` (optional), `notes` (optional)

### Examples

**Upload an incident:**
```
Upload an incident: "TypeError in auth module"
```

**Upload with details:**
```
Upload an incident with title "API timeout in production" 
with summary "Payment API timing out after 30s" 
and tags ["api", "performance", "production"]
```

**Search for similar incidents:**
```
Search for incidents about "null pointer exception"
```

```
Find similar incidents to "cannot read property of undefined"
```

**Workflow example:**
```
1. "Search for incidents about TypeError in map function"
2. (Review results, if no solution found)
3. "Upload incident: TypeError when calling map on undefined array, 
    fixed by adding null check, root cause was API returning null"
```

## How It Works

1. The MCP client calls tools like `ranked_solutions`, `add_solution`, `record_outcome`, `add_incident`
2. MCP server calls Debug Memory edge function endpoints
3. Edge function authenticates your API key and creates the incident
4. **MCP server generates embeddings** using `all-MiniLM-L6-v2` model
5. **Embeddings are uploaded** for title, summary, and error_signature fields
6. Incident is stored in your workspace with semantic search enabled

## Features

- 🚀 **Easy Integration**: One-command setup with `uv`
- 🔒 **Secure**: API keys stay in config, never exposed to LLM
- 🧠 **Semantic Search**: Auto-generates embeddings for intelligent search
- 🔍 **Find Solutions**: Search past incidents to find fixes for similar problems
- 📝 **Rich Incident Data**: Capture title, summary, error signatures, fixes, and more
- 🏷️ **Tagging**: Categorize incidents with custom tags

## Security

- ✅ API key stored in Cursor config (not in code)
- ✅ API key never exposed to LLM or conversation logs
- ✅ Edge function validates API key server-side
- ✅ No direct database access from MCP server
- ✅ Embeddings generated locally before upload

## Technical Details

- **Embedding Model**: `all-MiniLM-L6-v2` (384 dimensions)
- **Transport**: stdio (local execution)
- **Dependencies**: Managed with `uv`
- **Python**: 3.10+
