security

Secure Claude-powered applications by applying defense patterns like input sanitization, output filtering, and tool permission models to prevent prompt injection and data exfiltration. This skill provides concrete hardening steps to reduce these specific attack surfaces.

Implement PII detection and output filtering by applying defensible data handling controls to scan generated responses. This prevents leaking sensitive information by validating outputs against secure defaults before returning them to the end user.

Set up rate limiting and sandboxing for MCP-enabled workflows to limit tool abuse and restrict exposure. Applying these controls confines execution boundaries and mitigates malicious or excessive automated actions within the environment.

Yes, you can enforce least-privilege permission models and audit logging to prevent Claude tool abuse. Configuring strict access controls and recording actions ensures defensible tracking of all operations executed by the application.

You need threat modeling and secure defaults for end-to-end Claude integrations when deploying production applications handling untrusted inputs. This process identifies vulnerabilities and establishes baseline protections across the entire workflow.

Audit a Claude app for security gaps by evaluating input validation, permission models, and logging configurations. The review provides concrete hardening steps and code examples to immediately secure the identified vulnerabilities.
