Wires HeadlessEditorState + MCPBridge into a standalone whetstone_mcp binary that any MCP client (Claude Code, Cursor, etc.) can launch over stdio. No SDL, no ImGui, no OpenGL — headless only. 12/12 tests pass. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Sprint 9 Progress — Agent-First Tooling
Phase 9a: Standalone MCP Server
Step 245: HeadlessEditorState (no ImGui dependency)
Status: PASS (20/20 tests)
Created the headless agent API surface — same method interface as EditorState but with zero GUI dependencies (no ImGui, no SDL, no WebSocket).
Files created:
editor/src/ASTUtils.h— Pure AST utility functions extracted from EditorUtils.h (cloneModule, isAnnotationNode, countAnnotationNodes, findNodeById, findNodeAtPosition)editor/src/HeadlessEditorState.h— Lightweight state: HeadlessAgentState, HeadlessLibraryState, HeadlessBufferState, buffer management, orchestrator synceditor/src/HeadlessAgentRPCHandler.h— Full RPC dispatch mirroring AgentRPCHandler.h (20+ methods: getAST, parseSource, runPipeline, applyMutation, applyBatch, projectLanguage, generateCode, workflow recording, etc.)editor/tests/step245_test.cpp— 20 test cases covering construction, buffer management, RPC dispatch, permission enforcement, pipeline execution
Key design decisions:
- JSON roundtrip cloning (matching EditorUtils.h) instead of manual deep copy
- Separate HeadlessAgentState (no AgentMarketplace/WebSocket dependency chain)
- All files under 600-line architecture limit
Step 246: mcp_main.cpp — Standalone MCP Server Entry Point
Status: PASS (12/12 tests)
Wires HeadlessEditorState + MCPBridge into a standalone whetstone_mcp binary
that any MCP client (Claude Code, Cursor, etc.) can launch over stdio.
Files created:
editor/src/mcp_main.cpp— Standalone MCP server entry point with CLI arg parsing (--workspace, --language, --verbose), signal handling, resource reader lambda routing whetstone:// URIs, and MCPBridge stdio loopeditor/tests/step246_test.cpp— 12 test cases: initialize, notifications, tools/list (10+), resources/list (5), prompts/list (4), tools/call pipeline, tools/call get_ast, resources/read ast, resources/read diagnostics, ping, resources/read settings, CLI arg parsing
Key design decisions:
- No SDL, no ImGui, no OpenGL — headless only binary
- Fixed "mcp-session" session ID (MCP stdio is single-client)
- Default Refactor role for full MCP access
- Empty scratch buffer on startup so getAST works immediately
- All logging to stderr (stdout is the MCP transport)
