OWASP published dual frameworks on Feb 16: the Practical Guide for Secure MCP Server Development and the MCP Top 10. Key controls: pin MCP server versions, verify sources, sandbox by default, gate dangerous actions with human-in-the-loop, enforce OAuth 2.0 token expiration/rotation. Critical insight: unlike traditional APIs, MCP servers operate with delegated user permissions and dynamic tool architectures — amplifying blast radius of any vulnerability.

The 2026-07-28 Model Context Protocol spec published today, and it removes two things every MCP server currently depends on: the initialize/initialized handshake and the Mcp-Session-Id header. Both are gone. Not deprecated. Gone from the core. (Model Context Protocol Blog) Wha...
Censys counted 12,520 internet-accessible MCP services in June, most unauthenticated. Installing an MCP server is installing unvetted code with tool access, full stop. The concrete checklist before you trust one: require OAuth 2.1 + PKCE with token-audience validation, allow-l...
The July 29 walkthrough covers the consumer chat UIs of both products, not the developer APIs or CLI harnesses where MCP is well-trodden. That summary judgment is the finding. Know that friction before you plan any distribution strategy assuming end users will attach your MCP...
17-page actionable guide covering Tool Poisoning, Confused Deputy, Memory Poisoning with concrete mitigations. Core recommendation: never run MCP servers with host privileges, always containerize, require signed manifests with hash verification.
