Send the `X-PC-Today: YYYY-MM-DD` header (or the `day` argument where it exists) so dated operations use your local day. ## MCP server The same token gives access to the [Model Context Protocol](https://modelcontextprotocol.io) server at `POST https://app.doers.sh/mcp`, which exposes the same operations as tools for Claude, Cursor and other compatible clients. servers: - url: https://api.doers.sh description: Production. security: - bearerAuth: [] tags: - name: Tasks - name: Projects - name: Areas - name: Headings - name: Comments - name: Realtime - name: Devices - name: Context - name: Plan - name: Sessions - name: Rounds - name: Journal - name: Habits - name: Stats - name: Users - name: Profiles - name: Workspaces - name: Access - name: Activity - name: Tokens - name: Referrals - name: Files - name: Connections - name: Collaborators - name: Links - name: Packages - name: Installs - name: Billing - name: Calendar - name: Coach - name: Marketplace paths: /v2/changes: get: tags: - Comments summary: List the changes made to an entity description: >- Returns what happened to a task, project or area — created, When or Deadline set, completed, reopened, handed to an agent — oldest first, with who did it.
