Adding Custom Objects

This template includes tools for standard Attio objects (companies, people). To add tools for your custom objects:

1. Use get_workspace_schema to discover your workspace's objects and attributes

2. Copy an existing tool (e.g., search-companies.ts) as a template

3. Modify the API endpoint, fields, and types for your custom object

4. Register the new tool in src/tools/index.ts
