Agentalmanac: A Catalog of 23 MCP Servers with Paste-Ready JSON Configs
A Redditor built agentalmanac.org, a catalog of 23 MCP servers designed to eliminate the repetitive config setup when adding servers to Claude Desktop. Each server has a detail page with paste-ready JSON config snippets for three runtimes: Claude Desktop, Cursor, and Continue. You pick your runtime, copy the JSON, and you're done.
One notable finding: many of the “official” reference servers in modelcontextprotocol/servers are archived — including GitHub, Slack, Postgres, SQLite, Puppeteer, Sentry, Brave Search, and Google Drive. Yet most catalog sites still list them as current. The author manually routed every archived server to actively maintained alternatives:
- Puppeteer → Microsoft's Playwright
- Slack → Zencoder
- Brave Search → Brave's own first-party server
The author also hosts one server themselves: agentalmanac-time, a time utility (e.g., get_current_time, convert_time) running on a Cloudflare Worker. It's a proof of concept that MCP servers can run on Cloudflare Workers. Drop the snippet into claude_desktop_config.json and it works.
Stack details
- Catalog: Plain HTML/JS on Cloudflare Pages. Single
servers.jsonfetched client-side. No framework, no database, no build step. - Hosted MCP demo: Small Worker using Cloudflare's agents/mcp SDK with a Durable Object for session state. About four hours of work end to end.
- JSON feed available at
/servers.jsonfor building on top.
No signup or login required. If you want a server added, the author asks for a comment on the Reddit thread. They're also curious whether anyone would deploy servers through a hosted platform like this versus running on Railway or Fly.
