[Unreleased]

[0.3.0] - 2026-05-20

Added

• Added MCP outputSchema and annotations to listed tools.
• Added a standard structured tool result envelope with ok, tool, callId, summary, data, and follow-up refs.
• Added prefab workflow tools: inspect_prefab, validate_prefab_references, duplicate_prefab, edit_prefab_json, create_prefab_instance, inspect_prefab_instance, apply_prefab_instance, and revert_prefab_instance.
• Added get_performance_snapshot and expanded validate_scene with scene scale/performance-oriented counters.
• Added project AI instruction tools: list_project_instructions, read_project_instruction, write_project_instruction, and create_project_skill.
• Added tests for tool metadata, result envelopes, and project instruction helpers.

Changed

• Expanded the default core profile from 28 tools to 34 tools.
• Expanded the full profile from 76 tools to 89 tools.
• Updated tool interaction logs to store concise result summaries from the standard envelope.

[0.2.0] - 2026-05-20

Added

• Added a panel and tool-level update checker for comparing the installed extension version with the latest GitHub release.
• Added custom tool exposure with per-category and per-tool include/exclude configuration.
• Added get_tool_catalog, check_for_updates, get_recent_logs, search_project_logs, clear_logs, and validate_scene.
• Added MCP log resources: cocos://logs/editor and cocos://logs/project.
• Added in-memory runtime logs alongside the existing MCP interaction history.
• Added optional Streamable HTTP session support via enableSessions and Mcp-Session-Id.

Changed

• Expanded the default core profile from 22 tools to 28 tools.
• Expanded the full profile from 70 tools to 76 tools.
• Updated the Cocos panel to show installed version, update status, session toggle, and tool exposure controls.
• Tightened Streamable HTTP behavior for Accept headers, JSON-RPC notifications/responses, 202 Accepted, unsupported GET/SSE requests, and DELETE session termination.

Fixed

• Improved project log tailing so trailing blank lines do not hide the last useful log entries.

[0.1.4] - 2026-05-11

Fixed

• Fixed CI test expectations after expanding the documented core and full tool profiles.
• Aligned the latest release line with the current tested main branch state.

[0.1.3] - 2026-05-11

Added

• Added get_editor_state as a compact structured editor-state summary tool.
• Added get_selection and set_selection as explicit selection workflow tools for editor-side automation.
• Added persistence for the selected one-click MCP client target in the Cocos panel configuration.

Changed

• Expanded the default core profile from 19 tools to 22 tools by promoting editor-state and selection workflows.
• Expanded the full profile from 67 tools to 70 tools.
• Updated panel config persistence so changing the selected MCP client target no longer restarts the server unnecessarily.

[0.1.2] - 2026-04-30

Added

• Added Node.js unit tests for MCP protocol negotiation, tool profile exports, tool execution errors, and project file path safety.

Changed

• Updated the MCP initialize response to negotiate protocol version 2025-11-25 by default while retaining compatibility with older supported protocol versions.
• Added structuredContent to tool call results when a tool returns structured JSON data.
• Changed tool execution failures to return MCP tool errors instead of JSON-RPC internal errors, improving client-side self-correction.
• Updated CI to run the new Node.js test suite.

Security

• Restricted project file and asset-path resources to paths inside the active Cocos project root.
• Added HTTP request body size limits and invalid Origin header rejection for the embedded MCP server.

[0.1.1] - 2026-04-16

Added

• Added automatic port fallback when the configured MCP port is already occupied.
• Added actual-running-port reporting in MCP server status and panel state.
• Added .github/pull_request_template.md for repository contribution guidance.
• Added .github/workflows/ci.yml for lightweight GitHub validation.
• Added a lightweight GitHub Star promotion log after successful MCP server startup.

Changed

• Updated one-click MCP client configuration to write the actual running server port instead of the requested port when port fallback is active.
• Updated the MCP panel status line to show configured-port to actual-port fallback information.
• Updated the English and Chinese README files to document automatic port fallback behavior.

Fixed

• Fixed VS Code one-click configuration to use platform-specific config paths with macOS fallback behavior.
• Fixed Windows one-click MCP configuration path resolution by using a more reliable home/appdata lookup strategy.
