This server does not currently have a deployable release on Glama. Follow the repository's setup instructions to install and configure it for your MCP client, including any required credentials and local dependencies.
Replan a household's day when someone's work shift changes.
Alex has to stay late at work. Someone still needs to pick up the kids, collect groceries and make dinner. PlanPatch works out who can cover each task, accounts for travel time, and shows what has to move or wait until tomorrow.
Watch the demo — a 98-second walkthrough of the running app.
This is a small prototype for the Alexa+ track of the Amazon Developer Hackathon. It has a local web app and an MCP server; it hasn't been connected to Alexa+ yet.
You'll need Node.js 22+ and npm. No API key is needed.
npm ci
npm startOpen localhost:4178.
The demo uses a fictional family and four tasks. Try leaving Alex unavailable from 14:00 to 20:00 with no helper budget. Compare the suggested plans, review the changes, then apply one. The saved schedule survives a refresh; Undo last applied plan restores it.
Change the end time to 23:00 to see which optional task gets deferred. Allow Jo as a helper with a $12 budget to compare another option. That price is sample data, and applying a plan only updates local data.

With the server running, open another terminal:
npm run demo:mcpThe script connects through the MCP SDK, reads the household and requests a recovery plan. Use Review assistant proposal in the web app to open it.
The endpoint is http://127.0.0.1:4178/mcp, using Streamable HTTP with MCP 2025-11-25. For clients that accept this configuration:
{
"mcpServers": {
"planpatch": { "url": "http://127.0.0.1:4178/mcp" }
}
}Tool | What it does |
| Reads tasks, availability and the saved schedule |
| Computes alternatives without changing assignments |
| Retrieves a saved proposal |
Applying a plan is handled in the web app after review. Proposals expire after 30 minutes, and an old proposal can't overwrite a newer schedule.
The planner searches the sample day's time slots and possible assignees. It checks availability, travel time, workload, fixed appointments and the helper budget. Plans are ranked by deferrals, cost, reassignment and time changes. If an essential task can't be covered, it reports that rather than dropping the task.

State is stored in .data/, which is ignored by Git.
npm testTests cover scheduling constraints, impossible plans, helper permissions, persistence, expired or stale proposals, undo, and MCP calls over HTTP. Browser checks are recorded in docs/validation.md.
The planner handles one sample day, not overnight or multi-day schedules. Travel times and workload limits are fixed examples. There are no calendar, messaging, payment or booking connections.
The server is for local use and binds to 127.0.0.1. Cloud clients can't reach that address, and the app doesn't have multi-user authentication, so don't expose it publicly as-is.
Uses the MCP TypeScript SDK, Express and Zod.
