Data Coverage
4/8 security categories assessed
Score based on 4 of 8 categories. Missing categories could not be assessed due to lack of public data or vendor restrictions.
Evaluation Friction
Evaluation friction estimates how long it typically takes to fully evaluate this vendor's security practices, from initial contact to complete assessment.
2 Data Sources Blocked
This vendor is actively blocking 2 automated data collection sourcesthrough bot protection, authentication requirements, or access restrictions.
What this means: The security assessment may be incomplete because the vendor is restricting access to public security information. Manual verification may be required during procurement.
Security Documentation
These documents were discovered during automated assessment and may contain additional security information not reflected in the score.

AI Integration Security Assessment
Industry-first assessment evaluating whether Signal is safe and ready for AI agent integration. Covers AI security controls and readiness infrastructure for Anthropic's Model Context Protocol (MCP).
AI Integration Security
Industry-first assessment for AI agent safety
✅Excellent Security Features
- ●The parties derive new keys for every Double Ratchet message so that earlier keys cannot be calculated from later ones. The results of Diffie-Hellman calculations are mixed into the derived keys so that later keys cannot be calculated from earlier ones.
- ●Exceptional cryptographic key rotation: automatic per-message key derivation with forward secrecy
- ●Post-quantum security with PQXDH and ML-KEM Braid protocols
- ●Strong forward secrecy and post-compromise security guarantees
⚠️Security Gaps & Recommendations
- ●No oauth scopes
- ●No token expiration
- ●No service accounts
- ●No mfa enforcement
- ●No pii redaction
- ●No training opt out
- ●No data residency
- ●No gdpr compliance
- ●No read only tokens
- ●No granular permissions
AI Integration Security evaluates whether Signal is safe for AI agent access. This assessment considers authentication strength, access controls, observability capabilities, and data privacy protections when APIs are accessed by AI systems like Claude Code, GitHub Copilot, or custom AI agents.
AI Readiness Assessment
Evaluates readiness for AI agent integration
Official or community MCP server support
API docs, SDKs, code examples
API reference, auth flows, error handling
MCP Server Available
communitySignal supports Anthropic's Model Context Protocol (MCP) for secure AI agent integration.
View MCP Server💡Recommendations
- →⚠️ Official MCP server not found. Best alternative: https://github.com/awslabs/mcp (Trust: 50/100)
- →⚠️ ⚠️ Use with caution - review code before use
- →❌ Poor AI readiness - not recommended for AI workflows
AI Readiness measures whether Signalprovides the infrastructure and developer resources necessary for secure AI agent integration. High readiness indicates official MCP server support, comprehensive API documentation, and developer-friendly tools.
