Tools Discovery →What is the Eploy MCP Server?
A Eploy MCP server lets AI agents read and write Eploy data through the Model Context Protocol — Anthropic's open standard for connecting LLMs to external tools. StackOne's Eploy MCP server ships with 92 pre-built actions, fully extensible via the Connector Builder — plus managed authentication, prompt injection defense, observability, and agent execution runtime. Connect it from MCP clients like Claude Desktop, Claude Code, Cursor, Goose, and VS Code, or from agent frameworks like OpenAI Agents SDK, LangChain, and Vercel AI SDK.

Users
- Create User
Create a new user. Either RoleIDs or CopyPermissionsFromUserId must be provided — the provider returns 400 if neither is present. Each Contact can only have one user per UserTypeId; a second create for the same ContactId+UserTypeId combination returns 409 Conflict. Note: provider returns 500 when only required fields are submitted — including optional fields (e.g. Position, RoleIDs) in the payload avoids this (provider-side bug).

WeekCommencing must be in UTC format (e.g. 2026-01-05T00:00:00Z). Note: GET responses use TimesheetID (not Id) as the primary key field, and PlacementId is returned as Placement.Id nested object.
