## Summary
- Consolidates the MCP server from two endpoints (`/mcp` +
`/mcp/metadata`) into a **single `POST /mcp`** endpoint exposing five
high-level tools: `get_tool_catalog`, `learn_tools`, `execute_tool`,
`load_skills`, and `search_help_center`
- Fixes **DATABASE_CRUD tools not accessible via API key auth** by
removing an unnecessary `userId`/`userWorkspaceId` guard in
`DatabaseToolProvider` and threading `ApiKeyWorkspaceAuthContext`
through the tool context chain
- Improves tool descriptions with **STEP 1/2/3 workflow guidance** so AI
clients follow the correct discovery flow (catalog → learn → execute)
instead of guessing tool names
- Simplifies the **frontend AI settings** by removing the schema picker
dropdown (no more "Core Schema" vs "Metadata Schema" choice)
## Changes
### Backend
- **Deleted**: `mcp-metadata.controller.ts`, `mcp-metadata.service.ts`
(merged into core)
- **New**: `get-tool-catalog.tool.ts` — browsable, categorized tool
discovery
- **Fixed**: `DatabaseToolProvider.generateDescriptors` — removed guard
that blocked API key access to CRUD tools
- **Fixed**: `ToolContext` type + `ToolRegistryService` — `authContext`
now flows through so API key CRUD execution works end-to-end
- **Updated**: `McpProtocolService` — builds
`ApiKeyWorkspaceAuthContext` for API key requests
- **Updated**: All MCP tool descriptions with explicit step numbering
### Frontend
- **Simplified**: `SettingsAIMCP.tsx` — removed schema selector
dropdown, shows single MCP config
## Test plan
- [x] All 19 MCP unit tests pass (controller + protocol service)
- [x] Server and frontend lint clean
- [x] Server and frontend typecheck pass
- [x] Live-tested on localhost:3000 with API key: `get_tool_catalog`
returns 236 tools including 196 DATABASE_CRUD tools
- [x] Live-tested `execute_tool` with `find_companies` via API key —
returns real data
- [x] Tested MCP connection from Cursor IDE via project-level
`.cursor/mcp.json`
