## Quick Start
### Installation
```bash
cd cts_mcp
npm install
npm run build
```
**Note**: The server uses web-tree-sitter (WASM) for GDScript parsing. If the WASM file (`tree-sitter-gdscript.wasm`) is not available, the server will automatically fall back to a proven regex parser. See `docs/WASM_SETUP.md` for details.
### Usage
Start the MCP server (stdio transport):
```bash
node build/index.js
```
The server listens on stdin and writes to stdout using JSON-RPC 2.0 protocol.
## Tools
### 1. CTS_Export_to_Shrimp
Convert hop plan JSON to Shrimp tasks automatically.
**Input**:
```json
{
"hopPlanJson": "{\"phases\":[{\"name\":\"Phase 1\",\"hops\":[{\"id\":\"1.1\",\"name\":\"Setup\",\"description\":\"Initialize project\",\"estimatedLOC\":200,\"dependencies\":[]}]}]}"
}
```
**Output**:
```json
{
"success": true,
"tasksCreated": 1,
"taskIds": ["550e8400-e29b-41d4-a716-446655440000"]
}
```
**Example**:
```bash

```
### 3. CTS_Scan_Project_Signals
Scan Godot project for signal definitions.
**Input**:
```json
{
"projectPath": "/home/user/Godot/MyProject",
"includeEventBusOnly": true
}
```
**Output**:
```json
{
"success": true,
"signalsFound": 55,

## GDScript Integration
The CTS MCP server can be called from Godot GDScript using the `BDMCPClient` from the `bd_dev_tools` addon.
### Prerequisites
1. Install `bd_dev_tools` addon (contains `BDMCPClient`)
2. Build the CTS MCP server: `npm run build`
3. Ensure CTS MCP binary is accessible at `cts_mcp/build/index.js`
### Quick Start
```gdscript
extends Node
var mcp_client: BDMCPClient
func _ready() -> void:
# Initialize MCP client
mcp_client = BDMCPClient.new()
add_child(mcp_client)
# Register CTS MCP server
var error := CTSMCPConfig.register_cts_server(mcp_client)
if error != OK:
push_error("Failed to register CTS MCP server: ", error)
return
# Connect to server (starts stdio subprocess)
error = CTSMCPConfig.connect_to_cts_server(mcp_client)
if error != OK:
push_error("Failed to connect to CTS MCP server: ", error)
return
print("โ
CTS MCP server ready!")
# Example: Export hop plan to Shrimp
_export_example_hop()
func _export_example_hop() -> void:
var hop_plan := {
"phases": [{
"name": "Phase 1: Foundation",
"hops": [{
"id": "1.1",
"name": "Setup TypeScript Project",
"description": "Initialize npm project with TypeScript config",
"estimatedLOC": 200,
"dependencies": []
}]
}]
}
var response := CTSMCPConfig.call_export_to_shrimp(
mcp_client,
hop_plan,
"append", # updateMode: append, overwrite, selective, clearAllTasks
true # generateSubTasks
)
if response.has("error"):
push_error("โ Export failed: ", response.error.message)
return
print("โ
Tasks created: ", response.content.tasksCreated)
print("๐ Task IDs: ", response.content.taskIds)
```

**Hop Plan Schema**:
```gdscript
{
"phases": [
{
"name": "Phase Name",
"hops": [
{
"id": "1.1",
"name": "Hop Name",

```gdscript
var response := CTSMCPConfig.call_export_to_shrimp(
mcp_client,
{"phases": [...]},
"append",
true
)
print("Tasks created: ", response.content.tasksCreated)
```
### Advanced Usage
**Call other CTS tools directly:**
```gdscript
# CTS_Scan_Project_Signals
var scan_args := {
"projectPath": "/home/user/Godot/MyProject",
"includeEventBusOnly": true
}
var scan_response := mcp_client.call_tool("cts_mcp", "CTS_Scan_Project_Signals", scan_args)
print("Signals found: ", scan_response.content.signalsFound)
# CTS_Render_Artifact (Signal Map V2)
var artifact_args := {
"artifactType": "signal_map_v2",
"data": JSON.stringify({
"signals": scan_response.content.data.signals,
"filters": {}
})
}
var artifact_response := mcp_client.call_tool("cts_mcp", "CTS_Render_Artifact", artifact_args)
print("Artifact HTML saved to: ", artifact_response.content.filePath)
```
### Error Handling
```gdscript
# Check if CTS MCP server is available before calling
var error := CTSMCPConfig.register_cts_server(mcp_client)
if error == ERR_FILE_NOT_FOUND:
push_error("CTS MCP server not built. Run: cd cts_mcp && npm run build")
return
elif error != OK:
push_error("Failed to register CTS MCP server: ", error)
return
# Handle tool call errors
var response := mcp_client.call_tool("cts_mcp", "CTS_Export_to_Shrimp", arguments)
if response.has("error"):
push_error("Tool call failed: ", response.error.message)
push_error("Error code: ", response.error.code)
```
### Debugging
Enable debug logging in `BDMCPClient`:
```gdscript
# In autoload/EventBus.gd or your initialization script
EventBus.mcp_debug_enabled = true
# Now all MCP communication will be logged:
# [MCP] Sending request: {"jsonrpc":"2.0",...}
# [MCP] Received response: {"result":...}
```
Check CTS MCP server logs:
```bash
# Run CTS MCP server manually to see logs
node build/index.js
# Send test request
echo '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' | node build/index.js
```
### Testing
The CTS MCP integration is validated by GUT tests in `test/cts_mcp/test_cts_mcp_client.gd`.
**Run tests via Godot Editor:**
1. Open Godot Editor: `godot4 --path /home/eric/Godot/ProtoBd --editor`
2. Navigate to: Bottom Panel โ GUT โ Run Tests
3. Select `test/cts_mcp/test_cts_mcp_client.gd` in the test list
4. Click "Run" button
5. View results in GUT panel
**Test Coverage:**
- Server registration and connection
- Tool list retrieval
- CTS_Export_to_Shrimp calls with various hop plans
- Error handling (invalid arguments, server unavailable)

npm run build # Compilation (0 errors)
```
## Configuration
### Environment Variables
- `DEBUG=true` - Enable verbose logging
- `SHRIMP_MCP_PATH=/path/to/shrimp/build/index.js` - Custom Shrimp path
### Cache Configuration
Default cache settings in `src/artifacts/artifact_engine.ts`:
```typescript
private maxCacheSize = 50; // Max artifacts cached
private maxCacheAge = 3600000; // 1 hour (unused, artifacts are immutable)
```
## Troubleshooting
### Issue: "Shrimp MCP not found"
**Cause**: CTS_Export_to_Shrimp cannot reach Shrimp MCP server
**Solution**:
1. Ensure Shrimp MCP server is running
2. Check Shrimp path configuration
3. Verify stdio IPC permissions
### Issue: Artifact render timeout
**Cause**: Large dataset (100+ signals) exceeds render budget
**Solution**:
1. Filter signals before rendering (use `includeEventBusOnly: true`)
2. Increase timeout in VS Code extension
3. Phase 2 will add graph clustering
### Issue: TypeScript compilation errors
**Cause**: Missing type definitions or syntax errors
**Solution**:
```bash
npm install # Ensure dependencies installed
npm run build # Check for specific errors
```
