This reverts commit 0d8c03515888c62dc47186d4a3b0b7b04e78f8af.
* refactor(ai): ship Harness as optional companion
* fix(ai): support Harness companion on Windows
* test(ai): restore navigator after Harness Windows test
- Limit text reads and existence checks to platform discovery files
- Drop unused create and open capabilities
- Document restored desktop automation reconnection
The default capability only granted read_file/write_file/mkdir/remove/watch,
but the app also calls exists(), readTextFile(), create(), and open() from
@tauri-apps/plugin-fs. Each fs-plugin command requires its own explicit
permission identifier in Tauri v2 — these were never added.
The most visible symptom: EditorView's automation startup calls
discoveryFileExists()/readDiscoveryToken() (spawn.ts) to reuse an already-
running MCP server. With allow-exists and allow-read-text-file missing, both
calls silently fail (the fs-plugin IPC rejection is caught and treated as
"file not found"), so the app always falls through to spawning a redundant
MCP server process and registers with a freshly generated auth token instead
of the real one — which the already-running server then rejects, leaving
automation permanently disconnected from any already-running MCP server.
- Windows: npm installs .cmd wrappers, not direct executables. Spawn
via 'cmd /c openpencil-mcp-http' on Windows to resolve .cmd files.
- macOS/Linux: add fix-path-env-rs to inherit shell PATH in GUI apps.
- Add 'cmd' to shell spawn capabilities for Windows.
Fixes#226
- open_file: opens a .fig/.pen from disk into a new tab via MCP
- new_document: creates an empty doc with optional save path
- export_image, export_svg, get_jsx: optional path param writes output
to disk instead of returning base64/string (avoids flooding AI context)
- OPENPENCIL_MCP_ROOT env var scopes all file paths (defaults to cwd)
- setPlannedFilePath + startWatchingCurrentFile on editor store
- Extract openFileFromPath helper in use-menu.ts
- Add fs:allow-mkdir and scoped fs:allow-watch Tauri capabilities
- Better 'app not connected' error in stdio — instructs agent to stop
Co-authored-by: Jais Pedersen <jais@pedersens.net>
- Add packages/mcp/src/stdio.ts — proper stdio MCP server that
connects to the running app via WebSocket
- openpencil-mcp bin now points to stdio entry (was HTTP)
- openpencil-mcp-http bin added for the HTTP server
- Extract registerTools() from server.ts to share between transports
- Move index.ts banner output to stderr (prevents stdout corruption)
- Update Tauri shell spawn to use openpencil-mcp-http
- Update all docs (EN + 6 translations): correct binary names, source
paths, port number
Fixes#194
ACP agents now get an MCP server at http://127.0.0.1:7600/mcp that
proxies tool calls through the automation WebSocket to the browser,
where they execute against the live editor store. No separate
subprocess, no stale npm package — tools operate on the open canvas.
- Add /mcp endpoint to automation bridge (Streamable HTTP transport)
- Each MCP tool call → sendToBrowser({command:'tool'}) → browser executes
- Strip mcp__open-pencil__ prefix from tool names in chat UI
- Export paramToZod from MCP package for bridge reuse
Pass openpencil-mcp as a stdio MCP server to the ACP session so
agents get all design tools (create shapes, render JSX, export
images, etc.) instead of just plain conversation.
- Add makeFigma option to createServer for external FigmaAPI injection
- Skip file lifecycle tools (open/save/new) when using external FigmaAPI
- Pass MCP server config in ACP newSession mcpServers
- Add bun to Tauri shell scope for MCP server subprocess
- Add scoped command definitions for claude-code-acp, codex-acp, gemini
in Tauri shell plugin capabilities (required for Command.create)
- Show error banner in ChatPanel when transport initialization fails
instead of silently swallowing the error
Implement Agent Client Protocol (ACP) integration so users can use their
existing Claude Code, Codex, or Gemini CLI subscriptions directly in
OpenPencil's AI chat instead of managing separate API keys.
- Add ACPAgentDef/ACPAgentID types and ACP_AGENTS registry to core constants
- Create ACPChatTransport implementing Vercel AI SDK ChatTransport over ACP
- Spawn agent as subprocess via tauri-plugin-shell, communicate over stdio
- Map ACP session/update notifications to UIMessageChunk stream
- Update provider selector to show ACP agents alongside API-key providers
- Hide API key fields for ACP providers in setup/settings UI
- Add tauri-plugin-shell dependency and capability permissions
- ACP agents only appear in Tauri desktop builds (subprocess required)
Eliminates per-frame WASM allocations for shadows and blurs:
- Reusable effectLayerPaint instead of new Paint() per effect
- ImageFilter cache keyed by params (drop shadow, blur, decal blur)
- Zero allocations during SkPicture recording for cached effects
- Replace deflate with Zstd compression via zstd-wasm for .fig export
(Figma expects Zstd, not zlib deflate)
- Extract IS_TAURI constant from repeated window check
- Fix Tauri fs permissions: use allow-write-file / allow-read-file
with glob scope instead of bare allow-write / allow-read
