Frequently Asked Questions

What is Activitypub MCP?

Is Activitypub MCP safe to use?

We cannot tell you that, and nobody scanning at this scale can. What we did in March 2026 was shallow-clone Activitypub MCP and run five keyword searches over its source: auth identifiers, CORS configuration, rate-limit identifiers, the dependency manifest against a hardcoded list of 18 known-vulnerable packages, and unguarded eval/exec calls. None of them matched. A text search cannot follow a variable, judge intent, or tell you what a server does once it is running, so "nothing matched" is not "safe". What the scan does and does not cover is written out at /mcp/security.

What are alternatives to Activitypub MCP?

Similar MCP servers include Agent Skills Search Server, Airweave Search, Exa MCP Server. Each serves a similar purpose but may differ in features, language, and compatibility.
