A base64 string of 128+ characters appears in a documentation file. Encoded prompt injection hides the hostile instruction in base64 — invisible to keyword filters — and relies on the agent's ability to decode it at runtime. There is no normal authoring reason to embed a multi-hundred-byte base64 blob in skill docs.

What looks like documentation becomes an executable payload the agent may run without ever asking you.

MCP server for managing MCP server registries — health checks, duplicate detection, and configuration portability.
52% of remote MCP servers are dead. Only 9% are fully healthy. This server gives you a central registry to track what you have, what works, and what overlaps — before MCP sprawl becomes the microservices sprawl of 2018.
