# Simplenote MCP Server
A lightweight MCP server that integrates [Simplenote](https://simplenote.com/) with [Claude Desktop](https://github.com/johnsmith9982/claude-desktop) using the [MCP Python SDK](https://github.com/johnsmith9982/mcp-python-sdk).
This allows Claude Desktop to interact with your Simplenote notes as a memory backend or content source.

## 🚀 Quick Start
### Prerequisites
- Simplenote account (create one at [simplenote.com](https://simplenote.com/))
- Python 3.10+ (for non-Docker installs) or Docker
### Option 1: Docker (Recommended)
The fastest way to get started is using our pre-built Docker image:
```bash
# Pull and run the latest image
docker run -d \
--name simplenote-mcp \
-e SIMPLENOTE_EMAIL=your.email@example.com \
-e SIMPLENOTE_PASSWORD=your-password \
-p 8000:8000 \
docdyhr/simplenote-mcp-server:latest
```
**Docker Health Checks:** The container includes built-in health monitoring endpoints:
- Health: `http://localhost:8000/health`
- Readiness: `http://localhost:8000/ready`
- Metrics: `http://localhost:8000/metrics` (Prometheus format)
Or use Docker Compose:
```bash
# Clone the repository for docker-compose.yml
git clone https://github.com/docdyhr/simplenote-mcp-server.git
cd simplenote-mcp-server
# Set environment variables
export SIMPLENOTE_EMAIL=your.email@example.com
export SIMPLENOTE_PASSWORD=your-password
# Run with Docker Compose
docker-compose up -d
```
### Option 2: Smithery (One-click install)
Install automatically via [Smithery](https://smithery.ai/server/@docdyhr/simplenote-mcp-server):
```bash
npx -y @smithery/cli install @docdyhr/simplenote-mcp-server --client claude
```
This method automatically configures Claude Desktop with the MCP server.
### Option 3: Traditional Python Install
```bash
git clone https://github.com/docdyhr/simplenote-mcp-server.git
cd simplenote-mcp-server
pip install -e .
simplenote-mcp-server

## 🧪 Testing & Evaluation
### MCP Evaluations ✅
**Status**: ✅ **WORKING** - Complete mcp-evals integration with TypeScript wrapper!
This project includes comprehensive evaluations using [mcp-evals](https://github.com/mclenhard/mcp-evals) to ensure reliability and performance:
```bash
# Setup evaluation environment
npm install
npm run validate:evals
# Run evaluation suites
npm run eval:smoke # Quick smoke tests (2-3 minutes) ✅ VERIFIED
npm run eval:basic # Standard evaluations (5-10 minutes)
npm run eval:comprehensive # Full evaluation suite (15-30 minutes)
```
**Latest Test Results**: 4/5 tests passing excellently (avg 4.1/5):
- **Server Startup**: 4.6/5 ⭐ (Excellent)
- **Authentication**: 4.0/5 ⭐ (Good)
- **Note Operations**: 3.8/5 ⭐ (Good)
- **Search**: 5.0/5 ⭐ (Perfect)
- **Error Handling**: 1.4/5 ⚠️ (Needs improvement)
#### Evaluation Types
- **Smoke Tests**: Basic functionality validation
- **CRUD Operations**: Note creation, reading, updating, deletion
- **Search & Filtering**: Boolean search, tag filtering, date ranges
- **Error Handling**: Authentication, network issues, edge cases
- **Performance**: Large datasets, concurrent operations
- **Security**: Input validation, authentication enforcement
#### Automated Testing
Evaluations run automatically on:
- **Pull Requests**: Smoke + basic tests
- **Releases**: Comprehensive evaluation suite
- **Manual Trigger**: Full test matrix with detailed reporting
The evaluations use OpenAI's GPT models to assess:
- **Accuracy**: Correctness of responses
- **Completeness**: Thoroughness of results
- **Relevance**: Response appropriateness

- **Performance**: Operation efficiency
📁 See [`evals/README.md`](./evals/README.md) for detailed evaluation documentation.
### Traditional Testing
```bash
# Python unit tests
pytest
# Code quality checks
ruff check .
mypy simplenote_mcp
```
---
## 🛡️ Security
- **Token-based authentication** via environment variables
- **No hardcoded credentials** in Docker images
- **Security-hardened containers** with non-root users
- **Read-only filesystem** in production containers
- **Resource limits** to prevent abuse
---
## 🚨 Troubleshooting
### Common Issues
**Authentication Problems**:
- Verify `SIMPLENOTE_EMAIL` and `SIMPLENOTE_PASSWORD` are set correctly
- Check for typos in credentials
**Docker Issues**:
```bash
# Check container logs
docker-compose logs
# Restart services
docker-compose restart
# Rebuild if needed
docker-compose up --build
```
**Claude Desktop Connection**:
```bash
# Verify tools are available
./simplenote_mcp/scripts/verify_tools.sh
# Monitor logs
./simplenote_mcp/scripts/watch_logs.sh
```
### Diagnostic Commands
```bash
# Test connectivity
python simplenote_mcp/tests/test_mcp_client.py
# Check server status
./simplenote_mcp/scripts/check_server_pid.sh
# Clean up and restart
./simplenote_mcp/scripts/cleanup_servers.sh
```
---
## 📚 Development
### Quick Setup with mcp-evals
```bash
# One-command setup including evaluations
./setup-dev-env-with-evals.sh
# Or manual setup
git clone https://github.com/docdyhr/simplenote-mcp-server.git
cd simplenote-mcp-server
pip install -e ".[dev,test]"
npm install # For mcp-evals
```
### Local Development
```bash
# Run the server
python simplenote_mcp_server.py
# Run Python tests
pytest
# Run mcp-evals
npm run eval:smoke # Quick validation
npm run eval:basic # Standard tests
npm run eval:all # Full test suite
# Code quality
ruff check .
ruff format .
mypy simplenote_mcp
```
### Development Environment
The setup script creates:
- Python development environment with all dependencies
- Node.js environment for mcp-evals
- Example configuration files
- Pre-commit hooks
- Validation for all evaluation files
### Testing Strategy
1. **Unit Tests**: Traditional Python pytest for core logic
2. **Integration Tests**: MCP protocol compliance testing
3. **Smoke Tests**: Quick validation of basic functionality
4. **Evaluation Tests**: LLM-based assessment of real-world usage
5. **Performance Tests**: Load and stress testing
### Running MCP Evaluations
#### Docker Method (Recommended)
Due to potential permission issues with tsx, we recommend running MCP evaluations in Docker:
```bash
# Run smoke tests
./scripts/run-evals-docker.sh smoke
# Run basic evaluations
./scripts/run-evals-docker.sh basic
# Run comprehensive evaluations
./scripts/run-evals-docker.sh comprehensive
# Run all evaluations
./scripts/run-evals-docker.sh all
```
#### Direct Method (if permissions allow)
```bash
npm run eval:smoke
npm run eval:basic
npm run eval:comprehensive
npm run eval:all
```
### Docker Development
```bash
# Development with live code reload
docker-compose -f docker-compose.dev.yml up
# Build and test
docker build -t simplenote-mcp-server:test .
docker run --rm simplenote-mcp-server:test --help
```
