-
-```bash
-# Run all tests
-pytest tests/
-
-# Run with coverage report
-pytest tests/ --cov=src --cov-report=html --cov-report=term-missing
-
-# Run specific test file
-pytest tests/unit/test_encryption.py -v

-# Run with markers
-pytest -m unit          # Unit tests only
-pytest -m integration   # Integration tests only

-### Health Check
-
-```bash
-curl http://localhost:3000/health
-```
-
-### List Tools
-
-```bash
-curl -X POST http://localhost:3000/tools/list
-```
-
-### Test with Script
-
-```bash
-./test_server.sh
-```
-
-### Test in n8n
-
-Import `test_n8n.json` workflow for examples.
-
-### Coverage Goals
-
-Current coverage: 46% (61 tests passing)
-- **High coverage:** Authentication, encryption, scope validation (89%), connection pool management
-- **Low coverage:** Tool implementations, Odoo client methods (require live Odoo instance)
-
-To improve coverage:
-1. Run tests against real Odoo instance (see Phase 8 in development history)
-2. Mock Odoo responses in unit tests
-3. Use testcontainers for Odoo in CI/CD
-
-### Coverage Monitoring with Codecov
-
-This project uses [Codecov](https://codecov.io/) for continuous coverage tracking and reporting.
-
-**Coverage Tracking:**
-- View detailed coverage dashboard: https://codecov.io/gh/christopher-igweze/python-odoo-mcp
-- Coverage reports generated automatically on every push via GitHub Actions
-- Pull requests show coverage impact (lines added/removed/changed)
-- Coverage history graphs track improvements over time
-
-**Current Status:**
-- Overall coverage: 46% (target: 75%+)
-- Authentication & encryption: 89% ✅
-- Scope validation: 89% ✅
-- Tools & Odoo client: 15-29% (improving with mocked tests)
-
-**Understanding Coverage Reports:**
-1. **Line Coverage** - Percentage of source code lines executed during tests
-2. **Branch Coverage** - All code paths (if/else) tested
-3. **Uncovered Lines** - Listed with file paths for targeting improvement
-4. **Trending** - See if coverage increases or decreases with each commit
-
-**Local Coverage Reports:**
-
-Generate and view HTML coverage reports locally:
-
-```bash
-# Run tests with coverage
-pytest tests/ --cov=src --cov-report=html --cov-report=term-missing
-
-# View in browser
-open htmlcov/index.html  # macOS
-# or
-xdg-open htmlcov/index.html  # Linux
-```
-
-**For Contributors:**
-
-When implementing new features:
-1. Write tests alongside implementation
-2. Aim for 80%+ coverage on new code
-3. Run `pytest` to see coverage before pushing
-4. Codecov will comment on PRs showing impact
-5. Target overall coverage of 75%+

 ## Error Handling

-## Development
+## Note: REST API vs MCP Protocol
 
-Micro-commit workflow with glassbear format:
+This project exposes **MCP-style tools via HTTP REST API**, which is different from the official MCP protocol:
 
-```bash
-# Read the requirements
-cat requirements.txt
+- **This server:** REST API with HTTP endpoints (`/tools/list`, `/tools/call`)
+- **Official MCP protocol:** Used by Claude Desktop, Cursor, and other AI assistants via stdio or websockets
 
-# Make a change, test it
-# Then commit
-git commit -m "🔧 fix(scope): handle wildcard override"
-git push origin main
-```
+For AI assistant integration, see the excellent [ivnvxd/mcp-server-odoo](https://github.com/ivnvxd/mcp-server-odoo) which uses true MCP protocol.
 
-See `.git/logs` for commit history.
+This REST API approach is ideal for **n8n, webhooks, and automation platforms** where HTTP is more practical.
