# Every operation: API and MCP reference

Each operation is both an MCP tool (by its name) and a REST request under https://app.julius.dealsflow.ai/api/v1. The machine-readable version is the OpenAPI description.

The Julius Answer API has one list of operations, used by the REST API and the MCP server alike. Reading needs read access, day-to-day work needs write, and changing the setup needs admin. Inputs go in the path, the query string (for GET and DELETE) or a JSON body.

## Conventions
- **Ids** (call_id, contact_id, booking_id, task_id, question_id) come from the lists: list_calls, list_contacts, get_todo and get_today.
- **Times** like 09:00-17:00 are 24-hour, in the business's time zone. Dates are YYYY-MM-DD.
- **Phone numbers** can be typed any common way: (312) 555-0100 or +13125550100.
- **Partner keys** add X-Workspace-ID to every request here (or workspace to every MCP tool). The partner's own endpoints are on [the partner API page](/docs/partners/).
- **OpenAPI 3.1:** https://app.julius.dealsflow.ai/api/v1/openapi.json, with every input's schema.
