Openworkdays
Let your coding agent compute business-day offsets, ranges, and weekday checks without you wiring a calendar library or holiday dataset.
Overview
openworkdays is a MCP server for the Build phase that provides zero-signup business-day date math (add days, count days, is-business-day) over streamable HTTP.
What is this MCP server?
- Zero-signup hosted streamable-http MCP at openworkdays.vercel.app/api/mcp
- Business-day addition, day-count between dates, and is-business-day checks
- No API keys or local packages in the published server.json remotes config
- Version 0.1.0 with GitHub source at SolvoHQ/openworkdays
- Server version 0.1.0
- 1 streamable-http remote endpoint published in server.json
- Zero required environment variables in the manifest
What problem does it solve?
Hand-rolling business-day logic and holiday edge cases slows feature work and invites deadline bugs in agents-generated code.
Who is it for?
Indie builders who want quick business-day helpers in the agent during API or workflow development without standing up a calendar microservice first.
Skip if: Teams that need jurisdiction-specific public holiday calendars, timezone-aware scheduling, or audited compliance date engines without verifying API behavior.
What do I get? / Deliverables
After you register the remote MCP endpoint, your agent can query business-day calculations while you implement scheduling, billing, or SLA features.
- Agent-accessible business-day add, count, and check operations
- Faster deadline and billing-window logic while coding features
Recommended MCP Servers
Journey fit
Date math usually lands when you are implementing billing windows, SLA timers, or scheduling logic inside the product. This is a remote MCP integration you attach to the agent while building features that depend on correct business-day arithmetic.
How it compares
Remote date-math MCP utility, not a full project-management or cron service.
Common Questions / FAQ
Who is openworkdays for?
Solo and small-team builders who want their AI coding agent to handle business-day math while implementing deadlines, billing periods, or SLA timers.
When should I use openworkdays?
Use it during Build when you are wiring integrations or backend logic that must skip weekends and treat weekdays consistently.
How do I add openworkdays to my agent?
Add the streamable-http remote MCP URL https://openworkdays.vercel.app/api/mcp in your client’s MCP server list; no token is listed in the server manifest.
