## [2.35.3] - 2026-02-19
|
||||
|
||||
### Changed
|
||||
|
||||
- **Updated n8n dependencies**: n8n 2.6.3 → 2.8.3, n8n-core 2.6.1 → 2.8.1, n8n-workflow 2.6.0 → 2.8.0, @n8n/n8n-nodes-langchain 2.6.2 → 2.8.1
|
||||
- **Fixed node loader for langchain package**: Adapted node loader to bypass restricted package.json `exports` field in @n8n/n8n-nodes-langchain >=2.9.0, resolving node files via absolute paths instead of `require.resolve()`
|
||||
- **Fixed community doc generation for cloud LLMs**: Added `N8N_MCP_LLM_API_KEY`/`OPENAI_API_KEY` env var support, switched to `max_completion_tokens`, and auto-omit `temperature` for cloud API endpoints
|
||||
- Rebuilt node database with 1,236 nodes (673 from n8n-nodes-base, 133 from @n8n/n8n-nodes-langchain, 430 community)
|
||||
- Refreshed community nodes (361 verified + 69 npm) with 424/430 AI documentation summaries

## [2.35.2] - 2026-02-09
|
||||
|
||||
### Changed
|
||||
|
||||
- **MCP Apps: Disable non-rendering apps in Claude.ai**: Disabled 3 MCP Apps (workflow-list, execution-history, health-dashboard) that render as collapsed accordions in Claude.ai, and removed `n8n_deploy_template` tool mapping which renders blank content. The server sets `_meta` correctly on the wire but the Claude.ai host ignores it for these tools. The 2 working apps (operation-result for 6 tools, validation-summary for 3 tools) remain active. Disabled apps can be re-enabled once the host-side issue is resolved.

|

## [2.35.1] - 2026-02-09
|
||||
|
||||
### Fixed
|
||||
|
||||
- **MCP Apps: Fix UI not rendering for some tools in Claude**: Added legacy flat `_meta["ui/resourceUri"]` key alongside the nested `_meta.ui.resourceUri` in tool definitions. Claude.ai reads the flat key format; without it, tools like `n8n_health_check` and `n8n_list_workflows` showed as collapsed accordions instead of rendering their rich UI apps. Both key formats are now set by `injectToolMeta()`, matching the behavior of the official `registerAppTool` helper from `@modelcontextprotocol/ext-apps/server`.
