Deterministic web tools for AI agents: read URLs, metadata, email, scrape, RSS, DNS, SSL, HTTP.
Connect Web to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Deterministic web tools for AI agents: read URLs, metadata, email, scrape, RSS, DNS, SSL, HTTP. The web mcp server is what makes that connection.
Six small tools that AI agents and developers call constantly, each available both as a plain HTTP API and as an MCP server. No LLM in the loop, and no accounts or API keys for the free tier. Same input, same output. Boring and reliable on purpose.
The server ships on npm as package-guard-mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Configuration is passed through the environment: POSTHOG_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Plenty of team communication servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. It is maintained by mlawsonking; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
