Content Sanitization filters MCP-related content (including tool descriptions, tool outputs, error messages, and other data) to remove hidden content and instruction patterns using pattern-based detection combined with structural analysis. This mitigation applies sanitization at multiple points in the MCP pipeline to prevent prompt injection from various sources. Note that pattern-based filtering alone is insufficient and should be combined with other mitigations.
