Apertis Coworker — delegate grunt work to cheaper models

## Details

The Apertis MCP server now ships a **delegate coworker tool**. Connect it to Claude Code (or any MCP client) and Claude can hand off routine, high-volume subtasks — bulk edits, boilerplate, repetitive lookups — to a cheaper model through your Apertis API key, while staying in control as the "manager."

  ### What's new

  - **`delegate` tool** — Claude calls a single MCP tool to run a subtask on a
    lower-cost model, then reviews the result. You keep premium models for
    reasoning and spend cheap tokens on the busywork.
  - **Works with any MCP client** — Claude Code, Claude Desktop, and other
    MCP-compatible agents.
  - **One install** — available on npm as `@apertis/mcp-server`.

  ### Get started

  ```bash
  npx @apertis/mcp-server
  ```
  
  Add it to your MCP client config with your Apertis API key, and Claude can
  start delegating immediately.
