WebMCP Today: An Open-Source Package Manager Exposing Websites as AI Agent Tools

robertn702 · reddit · 2026-08-12

A developer released WebMCP Today, an open-source package manager for third-party WebMCP tools. WebMCP is a browser API that lets sites expose actions as structured tools for AI agents to call directly (e.g., invoking redditsearch), bypassing traditional UI navigation.

Since most sites don't natively support this protocol, the tool maps tools to existing HTTP APIs via versioned JSON packages. For security, packages cannot contain arbitrary JavaScript or DOM automation; requests stay on the package's site origin, and installations are pinned to approved versions.
