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.\n\n### Usage\n\nStart the MCP server (stdio transport):\n\n```bash\nnode build/index.js\n```\n\nThe server listens on stdin and writes to stdout using JSON-RPC 2.0 protocol.\n\n## Tools\n\n### 1. CTS_Export_to_Shrimp\n\nConvert hop plan JSON to Shrimp tasks automatically.\n\n**Input**:\n```json\n{\n \"hopPlanJson\": \"{\\\"phases\\\":[{\\\"name\\\":\\\"Phase 1\\\",\\\"hops\\\":[{\\\"id\\\":\\\"1.1\\\",\\\"name\\\":\\\"Setup\\\",\\\"description\\\":\\\"Initialize project\\\",\\\"estimatedLOC\\\":200,\\\"dependencies\\\":[]}]}]}\"\n}\n```\n\n**Output**:\n```json\n{\n \"success\": true,\n \"tasksCreated\": 1,\n \"taskIds\": [\"550e8400-e29b-41d4-a716-446655440000\"]\n}\n```\n\n**Example**:\n```bash\necho '{\n \"jsonrpc\": \"2.0\",\n \"id\": 1,\n \"method\": \"tools/call\",\n \"params\": {\n \"name\": \"CTS_Export_to_Shrimp\",\n \"arguments\": {\n \"hopPlanJson\": \"{\\\"phases\\\":[{\\\"name\\\":\\\"Phase 1\\\",\\\"hops\\\":[{\\\"id\\\":\\\"1.1\\\",\\\"name\\\":\\\"Setup Infrastructure\\\",\\\"description\\\":\\\"Initialize TypeScript project\\\",\\\"estimatedLOC\\\":200,\\\"dependencies\\\":[]}]}]}\"\n }\n }\n}' | node build/index.js\n```\n\n### 2.

Install `bd_dev_tools` addon (contains `BDMCPClient`)\n2. Build the CTS MCP server: `npm run build`\n3. Ensure CTS MCP binary is accessible at `cts_mcp/build/index.js`\n\n### Quick Start\n\n```gdscript\nextends Node\n\nvar mcp_client: BDMCPClient\n\nfunc _ready() -> void:\n # Initialize MCP client\n mcp_client = BDMCPClient.new()\n add_child(mcp_client)\n \n # Register CTS MCP server\n var error := CTSMCPConfig.register_cts_server(mcp_client)\n if error != OK:\n push_error(\"Failed to register CTS MCP server: \", error)\n return\n \n # Connect to server (starts stdio subprocess)\n error = CTSMCPConfig.connect_to_cts_server(mcp_client)\n if error != OK:\n push_error(\"Failed to connect to CTS MCP server: \", error)\n return\n \n print(\"✅ CTS MCP server ready!\")\n \n # Example: Export hop plan to Shrimp\n _export_example_hop()\n\nfunc _export_example_hop() -> void:\n var hop_plan := {\n \"phases\": [{\n \"name\": \"Phase 1: Foundation\",\n \"hops\": [{\n \"id\": \"1.1\",\n \"name\": \"Setup TypeScript Project\",\n \"description\": \"Initialize npm project with TypeScript config\",\n \"estimatedLOC\": 200,\n \"dependencies\": []\n }]\n }]\n }\n \n var response := CTSMCPConfig.call_export_to_shrimp(\n mcp_client,\n hop_plan,\n \"append\", # updateMode: append, overwrite, selective, clearAllTasks\n true # generateSubTasks\n )\n \n if response.has(\"error\"):\n push_error(\"❌ Export failed: \", response.error.message)\n return\n \n print(\"✅ Tasks created: \", response.content.tasksCreated)\n print(\"📋 Task IDs: \", response.content.taskIds)\n```\n\n### API Reference\n\n#### CTSMCPConfig.register_cts_server(client: BDMCPClient) -> Error\n\nRegisters the CTS MCP server configuration with the MCP client.\n\n**Parameters**:\n- `client`: BDMCPClient instance\n\n**Returns**: `Error` enum (OK or error code)\n\n**Example**:\n```gdscript\nvar error := CTSMCPConfig.register_cts_server(mcp_client)\nif error != OK:\n push_error(\"Registration failed: \", error)\n```\n\n#### CTSMCPConfig.connect_to_cts_server(client: BDMCPClient) -> Error\n\nConnects to the CTS MCP server (starts stdio subprocess).\n\n**Parameters**:\n- `client`: BDMCPClient instance (must be registered first)\n\n**Returns**: `Error` enum (OK or error code)\n\n**Example**:\n```gdscript\nvar error := CTSMCPConfig.connect_to_cts_server(mcp_client)\nif error != OK:\n push_error(\"Connection failed: \", error)\n```\n\n#### CTSMCPConfig.call_export_to_shrimp(client: BDMCPClient, hop_plan: Dictionary, update_mode: String, generate_sub_tasks: bool) -> Dictionary\n\nExports a hop plan to Shrimp MCP as tasks.\n\n**Parameters**:\n- `client`: BDMCPClient instance (must be connected)\n- `hop_plan`: Hop plan dictionary (see schema below)\n- `update_mode`: Task update mode (`\"append\"`, `\"overwrite\"`, `\"selective\"`, `\"clearAllTasks\"`)\n- `generate_sub_tasks`: Whether to split hops into subtasks\n\n**Returns**: Dictionary with keys:\n- `content`: `{ tasksCreated: int, taskIds: Array, details: Array }`\n- `error`: `{ code: String, message: String }` (if failed)\n\n**Hop Plan Schema**:\n```gdscript\n{\n \"phases\": [\n {\n \"name\": \"Phase Name\",\n \"hops\": [\n {\n \"id\": \"1.1\",\n \"name\": \"Hop Name\",\n \"description\": \"Hop description\",\n \"estimatedLOC\": 200,\n \"dependencies\": [\"0.9\"] # Optional\n }\n ]\n }\n ]\n}\n```\n\n**Example**:\n```gdscript\nvar response := CTSMCPConfig.call_export_to_shrimp(\n mcp_client,\n {\"phases\": [...]},\n \"append\",\n true\n)\nprint(\"Tasks created: \", response.content.tasksCreated)\n```\n\n### Advanced Usage\n\n**Call other CTS tools directly:**\n\n```gdscript\n# CTS_Scan_Project_Signals\nvar scan_args := {\n \"projectPath\": \"/home/user/Godot/MyProject\",\n \"includeEventBusOnly\": true\n}\nvar scan_response := mcp_client.call_tool(\"cts_mcp\", \"CTS_Scan_Project_Signals\", scan_args)\nprint(\"Signals found: \", scan_response.content.signalsFound)\n\n# CTS_Render_Artifact (Signal Map V2)\nvar artifact_args := {\n \"artifactType\": \"signal_map_v2\",\n \"data\": JSON.stringify({\n \"signals\": scan_response.content.data.signals,\n \"filters\": {}\n })\n}\nvar artifact_response := mcp_client.call_tool(\"cts_mcp\", \"CTS_Render_Artifact\", artifact_args)\nprint(\"Artifact HTML saved to: \", artifact_response.content.filePath)\n```\n\n### Error Handling\n\n```gdscript\n# Check if CTS MCP server is available before calling\nvar error := CTSMCPConfig.register_cts_server(mcp_client)\nif error == ERR_FILE_NOT_FOUND:\n push_error(\"CTS MCP server not built.

tools: scan_project_signals, analyze_project, suggest_refactoring\n - AST parsing with caching (<50ms per file, <1ms cached)\n - Headless CI/CD compatible (no native module compilation)\n- ✅ **MCP Tool Templates** (Tier 0):\n - TypeScript template: 460 lines, 5 sections (Zod, MCPError, logging, performance tracking)\n - Rust template: 483 lines, 5 sections (safe mutex, tracing, async/await)\n - Template compliance audit: 13 tools scored (avg 64/100, max 90/100)\n- ✅ **Architecture Enhancements**:\n - Signal contracts (Section 10): Cross-MCP data flow schemas\n - Performance budgets (Section 11): <100ms sync tools, <5s async tools\n - Integration topology (Section 12): Coordinator pattern documentation\n- ✅ **GDScript Integration**: MCPClient for CTS tool calling from Godot\n- ✅ **Breaking Changes**:\n - Requires Node.js 18+ (ESM modules, WASM support)\n - tree-sitter → web-tree-sitter (native bindings removed)\n - 9 total tools (5 existing + 4 new)\n\n**Metrics**:\n- Total Tools: 9 (5 existing + 4 new template-based)\n- Total LOC: ~4,500 (implementation) + ~1,200 (tests)\n- Performance: All tools meet <100ms sync / <5s async budgets\n- CTS Compliance: 100% (all files <500 lines)\n- Template Compliance: 90% (cts_export_to_shrimp reference implementation)\n\n### v1.0.0 (2025-10-30)\n\n**Phase CTS_MCP_1 Complete** ✅\n\n- ✅ MCP server with stdio transport\n- ✅ Shrimp integration (CTS_Export_to_Shrimp tool)\n- ✅ D3.js signal map renderer (force-directed graph)\n- ✅ React hop dashboard renderer (interactive filtering)\n- ✅ GDScript parser (signal extraction)\n- ✅ Artifact caching (SHA-256 + LRU)\n- ✅ 23 integration tests (100% pass rate)\n- ✅ 85% functional coverage\n\n**Metrics**:\n- Total LOC: 1,097 (implementation) + 450 (tests)\n- Performance: 97.7% faster than targets\n- CTS Compliance: 100% (all files <500 lines)\n\n## Roadmap\n\n### Phase 2 (Planned)\n- Dependency graph renderer (visualize hop dependencies)\n- Performance chart renderer (LOC over time)\n- Graph clustering (100+ signal support)\n- Tree-sitter GDScript parser (robust signal extraction)\n\n### Phase 3 (Future)\n- Sandpack integration (game visualizers)\n- Scene preview renderer\n- Interactive mechanic demos\n\n---\n\n**Maintained by**: Development Team \n**Questions?**: See [MCP_PROTOCOL.md](../docs/MCP_PROTOCOL.md) or open an issue\n","name","English","tag","en-US",{"_42":43,"_13":44,"_52":32,"_53":32,"_33":34,"_16":54,"_55":56,"_82":83,"_90":-5,"_91":-5,"_92":93,"_138":139,"_143":-5,"_63":126,"_144":130,"_66":145,"_146":147},"addedAt","2025-11-04T16:01:17.427582Z",[45,46,47,48,49,50,51],"category:developer-tools","category:project-management","category:code-analysis","environment:local","hosting:hybrid","language:html","license_grade:f","descriptionMarkdown","descriptionPlainText",13692,"integrations",[57,68,75],{"_58":59,"_31":65,"_66":67},"brand",{"_60":61,"_37":62,"_63":64},"logoSvgPath","M13.983
