dy-mcp-demo

A public, unauthenticated demo of dy-mcp — an MCP personal-context server. Lets you poke at every tool the server exposes without needing to install or configure anything.

Live at: https://demo-mcp.dyuhaus.com

• Open the URL in a browser to see the Editorial-style web companion.

• Or point any MCP-aware client (Claude Desktop, Claude Code, etc.) at https://demo-mcp.dyuhaus.com/mcp — no auth header required.

The data is invented (a fictional writer-developer named "Alex Quinn") and the whole database resets every hour, so feel free to create, edit, or delete anything. You won't break it.

For the real, password-protected server this is cloned from, see dyuhaus/dy-mcp.

What's the same as dy-mcp?

Everything to do with the MCP protocol and the data model:

• Six typed contexts: project, idea, preference, writing_style, skill, general.

• All 12 tools: get_personal_context, list_contexts, get_context, add_context, update_context, delete_context, search_contexts, import_project, import_project_section, list_project_files, get_project_file, delete_project_file.

• All 7 resources under context://.

• Same SQLite schema, same storage code, same importer, same HTTP routes.

What's different?

• No auth. /auth/*, /oauth/*, /.well-known/*, session cookies, password bootstrap — all removed. /mcp is open. The web UI boots straight into the dashboard.

• Hourly reset. A scheduled task wipes the DB and reseeds it with the fictional persona (see scripts/seed.ts).

• Default port is 7879 so it can run alongside the main dy-mcp on the same machine.

• Web sidebar shows "PUBLIC DEMO" and a "resets hourly" note.

Run the demo locally

npm install
npm run build
npm run seed       # wipe + reseed the demo DB
npm run web:build
npm run start:api  # http://localhost:7879

The web UI is served at the same port as the API.

Dev loop:

npm run dev:api    # backend with tsx watch
npm run web:dev    # vite dev server on :5173

HTTP endpoints

Hosting

The included scripts/install-demo-task.ps1 registers two Windows scheduled tasks:

1. dy-mcp-demo-api — runs the built server on :7879 at boot.

2. dy-mcp-demo-reset — runs scripts/seed.ts every hour via tsx.

Point a Cloudflare tunnel at http://localhost:7879 under the hostname of your choice. See CLAUDE.md for the exact commands.
