# Create workflow MCP server (/api-reference/mcp-servers/createWorkflowMcpServer)

`POST /api/v2/workflow-mcp-servers`

## Description
Create an MCP server exposing deployed workflows as tools. Every supplied workflow must already be deployed. With `isPublic: true`, anyone holding the server URL can execute its workflows without a Sim API key. Requires workspace Admin access. Workspace API keys return `403`; use a personal API key or scoped OAuth token.

OAuth scope: `api:write`.

## Request Body

A new workflow MCP server and deployed workflows to expose as tools.

### 403 — The caller lacks the rights this operation requires. When the cause is one a caller can act on, `error.details.code` names it. A resource in a workspace the caller cannot reach at all answers `404` instead, so absence and denial are indistinguishable.
