Because MCP uses a dynamic JSON-RPC transport that negotiates schemas in real-time, it creates a large interception surface beyond typical REST APIs. Key attack vectors include Schema Manipulation (injecting malicious tool definitions) and Cross-Agent Poisoning in multi-agent chains. The recommended defense is a Hybrid PQC/Classical approach using NIST FIPS 203/204 algorithms layered over existing TLS, preserving backwards compatibility while adding quantum resistance. A three-phase roadmap covers assessment of all MCP connections, hybrid transition for sensitive endpoints, and eventual full post-quantum migration as legacy systems are retired. ## Full article daily.dev links to this article rather than hosting it.
