### Description (declared)

# Canon Keeper MCP Server

An MCP (Model Context Protocol) server that persists learnings from Copilot conversations to `copilot-instructions.md`.

**No API key required!** Copilot extracts learnings using its own LLM, this tool handles deduplication and formatting.

## Quick Install

```bash
pip install canon-keeper-mcp
python -m canon_keeper_mcp install

# Or specify a workspace
python -m canon_keeper_mcp install --workspace /path/to/project
```

The installer will:

1. ✅ Configure `.vscode/mcp.json` with the canon-keeper server
2. ✅ Enable MCP in `.vscode/settings.json`
3. ✅ Create/update `.github/copilot-instructions.md` with:
   - Memory Persistence Protocol (`@History` directive)
   - Best practices template
   - Session Learnings Log table

## Features

- **Zero Configuration**: No API keys needed - uses Copilot's built-in LLM
- **Smart Deduplication**: Uses Jaccard similarity to avoid duplicate entries
- **Simple Integration**: Works with Copilot's existing capabilities
- **Markdown Formatting**: Returns properly formatted table rows for the Session Learnings Log

## Usage

After installation, reload VS Code and use these trigger phrases in any Copilot chat:

```
User: @History save what we learned
User: save this learning  
User: remember this
User: add to memory
```

Copilot will:

1. Extract learnings from the conversation (using its own LLM)
2. Call the MCP tool to deduplicate against existing entries
3. Append new learnings to your `copilot-instructions.md`
4. Report what was saved/skipped

## Manual Installation

If you prefer to install manually:

### 1. Install the package

```bash
pip install canon-keeper-mcp
```

### 2. Configure MCP server

Add to `.vscode/mcp.json`:

```json
{
  "servers": {
    "canon-keeper": {
      "type": "stdio",
      "command": "/path/to/your/python",
      "args": ["-m", "canon_keeper_mcp"]
    }
  }
}
```

> **Note:** Replace `/path/to/your/python` with the absolute path to your Python executable (e.g., `C:/Users/You/p…
