-# FastMCP Testing Fixes Summary
-
-## Issues Found and Fixed
-
-### 1. Arduino Sketch Tests (`test_arduino_sketch.py`)
-**Issue**: The `create_sketch` method calls `_open_file()` which opens sketch files in text editor during test runs.
-
-**Fixed**:
-- Added `with patch.object(sketch_component, '_open_file'):` to `test_create_sketch_already_exists`
-- Pattern: Mock `_open_file` method to prevent file opening during tests
-
-**Status**: ✅ FIXED - All Arduino sketch tests now pass
-
-### 2. Integration Tests (`test_integration.py`)
-**Issues**:
-- Incorrect FastMCP resource access pattern: Used `.content` instead of `.read()`
-- Incorrect FastMCP tool invocation pattern: Used `.invoke()` instead of `.run(arguments_dict)`
-- Attempted to access `mcp_server.app.sketch_component` which doesn't exist
-- Tools require active FastMCP context to run, causing "No active context found" errors
-
-**Partially Fixed**:
-- ✅ Resource access: Changed from `resource.content` to `await resource.read()`
-- ✅ Tool invocation method: Changed from `tool.invoke()` to `tool.run({})`
-- ❌ Context issues: Tools still need proper FastMCP context management
-- ❌ Component access: Tests try to access non-existent `mcp_server.app` attribute
-
-**Status**: 🟡 PARTIALLY FIXED - 10/18 tests pass, 8 still fail due to context issues
-
-## Proper FastMCP Testing Patterns
-
-### Resource Access Pattern
-```python
-# ❌ Incorrect
-resource = await mcp_server.get_resource("uri")
-content = resource.content
-
-# ✅ Correct
-resource = await mcp_server.get_resource("uri")
-content = await resource.read()
-```
-
-### Tool Invocation Pattern
-```python
-# ❌ Incorrect
-tool = await mcp_server.get_tool("tool_name")
-result = await tool.invoke(param1="value1")
-
-# ✅ Correct
-tool = await mcp_server.get_tool("tool_name")
-result = await tool.run({"param1": "value1"})
-```
-
-### Component Method Mocking
-```python
-# ❌ Incorrect (for integration tests)
-with patch.object(mcp_server.app.sketch_component, '_open_file'):
-
-# ✅ Correct (for component tests)
-with patch.object(sketch_component, '_open_file'):
-```
-
-## Recommended Next Steps
-
-### Option 1: Use FastMCP Testing Utilities
-Rewrite integration tests to use `run_server_in_process` from `fastmcp.utilities.tests`:
-
-```python
-from fastmcp.utilities.tests import run_server_in_process
-
-def test_server_integration():
- with run_server_in_process(create_server, config) as server_url:
- # Make HTTP/MCP requests to server_url
- # This provides proper context management
-```
-
-### Option 2: Simplify Integration Tests
-Focus integration tests on:
-- Server creation and component registration
-- Tool/resource metadata validation
-- Resource content validation (without execution)
-- Error handling for invalid configurations
-
-Remove complex workflow tests that require tool execution with context.
-
-### Option 3: Use Component-Level Testing
-Move detailed functionality tests to component-level tests where proper mocking can be applied:
-- `test_arduino_sketch.py` - ✅ Already working
-- `test_arduino_library.py`
-- `test_arduino_board.py`
-- etc.
-
-## Files Modified
-
-### `/home/rpm/claude/mcp-arduino-server/tests/test_arduino_sketch.py`
-- Added `_open_file` mocking to `test_create_sketch_already_exists`
-- All tests now pass ✅
-
-### `/home/rpm/claude/mcp-arduino-server/tests/test_integration.py`
-- Fixed resource access patterns (10 tests now pass)
-- Fixed tool invocation method signatures
-- Updated error condition assertions
-- 8 tests still failing due to context management issues
-
-## Security & Best Practices Applied
-
-1. **File Opening Prevention**: All `_open_file` calls are mocked to prevent opening text editors during tests
-2. **Subprocess Mocking**: Arduino CLI calls are properly mocked with `patch('subprocess.run')`
-3. **Error Handling**: Tests properly handle error conditions (missing arduino-cli, etc.)
-4. **Isolation**: Tests use temporary directories and proper cleanup
-
-## FastMCP Architecture Compliance
-
-The fixes follow proper FastMCP patterns:
-- Resources use `.read()` method for content access
-- Tools use `.run(arguments_dict)` method for execution
-- Components are tested in isolation with proper mocking
-- Integration tests focus on metadata and registration, not execution

+# MCP Arduino Server - Sampling Support Documentation
+
+## Overview
+
+The Arduino MCP Server supports dual-mode operation for AI-powered features like WireViz circuit diagram generation from natural language descriptions. This document explains how the server handles both clients with sampling support and those without.
+
+## What is MCP Sampling?
+
+MCP Sampling is a capability where MCP clients can provide LLM (Large Language Model) functionality to MCP servers. This allows servers to request AI completions from the client's underlying model. It's essentially the reverse of the typical flow - instead of the client asking the server for data, the server asks the client to generate content using AI.
+
+## The Dual-Mode Approach
+
+The Arduino MCP Server implements a progressive enhancement strategy:
+
+1. **Always Try Sampling First**: For clients that support sampling, we get AI-generated content
+2. **Graceful Fallback**: For clients without sampling, we provide intelligent templates
+3. **Never Remove Functionality**: All features work for all clients, just with different levels of sophistication
+
+## Client Compatibility
+
+### Clients WITH Sampling Support
+- **Cursor**: Full sampling support ✅
+- **VS Code MCP Extension**: Full sampling support ✅
+- **Custom MCP Clients**: If they declare and implement sampling ✅
+
+### Clients WITHOUT Sampling Support
+- **Claude Desktop (claude-code)**: No sampling support ❌
+ - Does not declare sampling capability in handshake
+ - Does not implement `sampling/createMessage` endpoint
+ - Falls back to intelligent templates
+
+## How WireViz Generation Works
+
+### With Sampling (AI-Powered)
+```python
+# When client supports sampling:
+1. User: "Generate circuit for LED with button"
+2. Server → Client: "Please generate WireViz YAML for this description"
+3. Client → Server: [AI-generated custom YAML]
+4. Server: Renders diagram from AI-generated YAML
+```
+
+### Without Sampling (Template-Based)
+```python
+# When client doesn't support sampling:
+1. User: "Generate circuit for LED with button"
+2. Server: Detects keywords ("LED", "button")
+3. Server: Selects appropriate template
+4. Server: Renders diagram from template YAML
+```
+
+## Intelligent Template Selection
+
+When sampling isn't available, the server provides smart templates based on keywords:
+
+| Keywords | Template Type | Components Included |
+|----------|--------------|-------------------|
+| `led` | LED Circuit | Arduino, LED with resistor, connections |
+| `motor`, `servo` | Motor Control | Arduino, Servo/Motor, power connections |
+| `sensor` | Sensor Circuit | Arduino, Generic sensor, analog/digital inputs |
+| `button`, `switch` | Button Input | Arduino, Push button, pull-up resistor |
+| `display`, `lcd`, `oled` | Display Circuit | Arduino, I2C display, SDA/SCL connections |
+| *(none of above)* | Generic | Arduino, customizable component, basic connections |
+
+## Technical Implementation
+
+### Capability Detection
+```python
+# Check if client has sampling capability
+if hasattr(ctx, 'sample') and callable(ctx.sample):
+ try:
+ result = await ctx.sample(messages, max_tokens=2000)
+ # Use AI-generated content
+ except Exception as e:
+ # Fall back to templates
+```
+
+### FastMCP Context Patch
+
+For Claude Desktop, we've applied a patch to FastMCP to bypass the capability check since Claude Desktop has the underlying capability but doesn't declare it properly:
+
+**Location**: `.venv/lib/python3.11/site-packages/fastmcp/server/context.py`
+
+**Change**: Set `should_fallback = False` to always attempt sampling even when not declared
+
+## Error Handling
+
+The server handles various failure scenarios:
+
+1. **Client doesn't declare sampling**: Use templates
+2. **Client declares but doesn't implement**: Catch "Method not found", use templates
+3. **Sampling returns empty**: Use templates
+4. **Network/timeout errors**: Use templates
+
+## Benefits of This Approach
+
+1. **Universal Compatibility**: Works with ALL MCP clients
+2. **Progressive Enhancement**: Better experience for capable clients
+3. **Predictable Fallback**: Always produces useful output
+4. **No Breaking Changes**: Existing functionality preserved
+5. **User-Friendly**: Clear feedback about which mode was used
+
+## Testing
+
+Run the test script to verify template generation:
+```bash
+python test_wireviz_sampling.py
+```
+
+## Future Improvements
+
+1. **Enhanced Templates**: More circuit types and components
+2. **Template Customization**: User-defined template library
+3. **Hybrid Mode**: Combine templates with partial AI generation
+4. **Client Detection**: Better identification of client capabilities
+5. **Caching**: Remember which clients support sampling
+
+## Troubleshooting
+
+### "Method not found" Error
+- **Cause**: Client doesn't implement sampling endpoint
+- **Solution**: Automatic fallback to templates
+
+### Templates Instead of AI Generation
+- **Cause**: Client doesn't support sampling
+- **Solution**: Working as designed - customize the template YAML manually
+
+### Wrong Template Selected
+- **Cause**: Keywords might match multiple templates
+- **Solution**: Template selection order prioritizes displays over LEDs
+
+## For Developers
+
+### Adding New Templates
+
+1. Add keyword detection in `_generate_template_yaml()`
+2. Create new template method (e.g., `_generate_relay_template()`)
+3. Include appropriate components and connections
+4. Test with various descriptions
+
+### Debugging Sampling Issues
+
+Enable debug logging:
+```python
+import logging
+logging.basicConfig(level=logging.DEBUG)
+```
+
+Use client debug tools:
+```bash
+# Check what capabilities the client declared
+mcp-arduino-server client_declared_capabilities
+
+# Test sampling support
+mcp-arduino-server client_test_sampling
+```
+
+## Conclusion
+
+The dual-mode approach ensures that the Arduino MCP Server provides value to all users, regardless of their client's capabilities. Users with sampling-capable clients get AI-powered features, while others get intelligent templates that provide excellent starting points for their circuits.

-MCP Server for Arduino CLI, File Management, and WireViz using FastMCP (v2.3 - Auto Open Files)
-
-Provides tools for managing Arduino projects via the `arduino-cli`, generating
-circuit diagrams using WireViz, and basic file operations.
-
-Core Features:
-- Sketch Management: Create, list, read, and write Arduino sketches.
- - **New:** Automatically opens the created `.ino` file in the default editor after `create_new_sketch`.
- - Writing `.ino` files within the designated sketch directory automatically
- triggers compilation using a specified or default FQBN.
-- Code Verification: Compile sketches without uploading using `verify_code`.
-- Uploading: Compile and upload sketches to connected boards.
-- Library Management: Search the online index and local platform libraries,
- install libraries, and list examples from installed libraries.
-- Board Management: Discover connected boards and search the online index.
-- File Operations: Basic, restricted file renaming and removal within the user's
- home directory.
-- WireViz Integration:
- - `get_wireviz_instructions`: Provides basic usage instructions for WireViz.
- - `generate_diagram_from_yaml`: Generates circuit diagrams from YAML.
- - **New:** Automatically opens the generated `.png` file in the default image viewer.
-
-Key Enhancements in this Version (v2.3):
-- **Auto-Open Functionality:** Added helpers to open created/generated files
- (`.ino`, `.png`) in their default system applications after successful tool execution.
-- Split WireViz functionality into two tools: one for instructions, one for generation.
-- Added `get_wireviz_instructions` tool (now a resource).
-- Returns generated PNG image data directly via MCP ImageContent in `generate_diagram_from_yaml`.
-- Improved Readability: Enhanced docstrings, type hints, logging, and code structure.
-- Robust Error Handling: More specific exceptions, clearer error messages,
- better handling of CLI command failures and path issues.
-- Refined Path Validation: Stricter checks for file operations to prevent
- access outside allowed directories (User Home or specific Arduino paths).
-- Consistent Logging: Standardized log message formats and levels.
-- Dependency Checks: Clearer messages if dependencies like `mcp` or `thefuzz`
- are missing.
-- Security Emphasis: Stronger warnings in docstrings for potentially
- destructive operations (`write_file`, `rename_file`, `remove_file`).
-- ANSI Code Stripping: Fixed potential issues in parsing `lib examples` output.
-- Auto-Compile Logic: Clarified FQBN handling for `write_file` auto-compile.
-
-Configuration Defaults:
-- Sketches Base Directory: ~/Documents/Arduino_MCP_Sketches/
-- Build Temp Directory: ~/Documents/Arduino_MCP_Sketches/_build_temp/
-- Arduino Data Directory: Auto-detected (~/.arduino15 or ~/Library/Arduino15)
-- Arduino User Directory: ~/Documents/Arduino/
-- Arduino CLI Path: Auto-detected via `shutil.which` and common paths,
- defaults to 'arduino-cli'. Can be overridden via ARDUINO_CLI_PATH env var.
-- WireViz Path: Auto-detected via `shutil.which`, defaults to 'wireviz'.
- Can be overridden via WIREVIZ_PATH env var.
-- Default FQBN (for auto-compile): 'arduino:avr:uno'
-
-Prerequisites:
-- Python 3.8+
-- `arduino-cli` installed and accessible in the system PATH or common locations.
-- `wireviz` installed and accessible in the system PATH.
-- MCP SDK: `pip install "mcp[cli]"`
-- Fuzzy Search (Optional but Recommended): `pip install "thefuzz[speedup]"`
-
-Debugging Tips:
-- Check Server Logs: Detailed errors from `arduino-cli` and `wireviz` are logged.
-- Permissions: Ensure user has access to sketch/data/user/build directories,
- serial ports, and can execute `wireviz`.
-- Environment PATH: Verify `arduino-cli`, `wireviz`, and required toolchains
- are in the PATH accessible by the server process.
-- Cores/Toolchains: Use `arduino-cli core install ` if compilation fails.
-- "No such file or directory": Check paths, missing core tools, or sketch paths.

-Arduino Connection Diagram YAML Guidelines for WireViz
-
-Use these rules to create valid YAML files:
-
-1. CONNECTORS
- • List every component: Include Arduino, sensors, LEDs, resistors, and power supplies.
- • Detail pins: Use pinlabels to list pins in order.
- • Annotate: Define the type and add notes as needed.
- • Simple components: For resistors, capacitors, and non-LED diodes, use:
-
-ComponentName:
- style: simple
- type: Resistor
- category: ferrule
- subtype: [resistance] Ω
-
-
-
-2. CABLES
- • Define cable bundles: Specify colors, category, and display options such as show_name, show_wirecount, and show_wirenumbers.
-
-3. CONNECTIONS
- • Reference only defined components: Every connection must use components from the CONNECTORS section.
- • Match pin counts: Each connection set must list the same number of pins/wires.
- • Group logically: Organize connections by component.
- • Use position numbers only: Use numerals (e.g., [1], [2-4]) rather than pin names like “GND” or “VCC”. (Do not confuse these with digital labels like “D2”.)
- • Ferrule notation: Use --> for direct connections with ferrules.
- • Order matters:
- • List ferrule-involved connections first.
- • Do not end any connection set containing a ferrule.
- • Follow with connections that have no ferrules.
- • Simplify: Combine similar connections when possible.
-
-4. METADATA
- • Include keys: description, author, and date.

-Checklist
- 1. Every component in CONNECTIONS must be defined in CONNECTORS.
- 2. Pin position numbers in CONNECTIONS must match the wire count.
- 3. All connections should use cables or the --> notation.
- 4. Do not make direct component-to-component connections without cables or ferrules.
- 5. List ferrule-dependent connections first.
- 6. Combine similar connections for simplicity.
- 7. End connection sets with components that are not ferrules or cables.
- 8. Use only components defined in the circuit; do not add new ones in CONNECTIONS.
- 9. Every connection set must reference the same number of wires.

-- **Automatic Roots Detection**: Uses client-provided roots when available
-- **Environment Override**: MCP_SKETCH_DIR overrides roots
-- **Fallback Support**: Uses defaults if no roots or env vars
-- **60+ Tools**: Complete Arduino development toolkit
-- **Memory-Safe Serial**: Circular buffer prevents crashes
-- **Professional Debugging**: GDB integration with breakpoints
-
-## How Directory Selection Works:
-1. Check for MCP client roots (automatic)
-2. Check MCP_SKETCH_DIR environment variable
-3. Use default ~/Documents/Arduino_MCP_Sketches
