fastmcp-client-cli

MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 0.90). The CLI can list and call arbitrary HTTP/HTTPS MCP servers and include their resources/prompts (e.g., fastmcp list http://server/mcp, fastmcp call http://server/mcp, and the --resources/--prompts flags), so it will ingest and display untrusted third-party content from external servers that could contain injected instructions.
