MCP extension stops responding after Claude Desktop update — protocol version mismatch | Figma Forum

[STRONG] "Claude Desktop now negotiates 2025-11-25, while the Figma extension responds with 2025-06-18" — Article documents a direct protocol version incompatibility causing tool execution failure. The version mismatch (2025-11-25 vs 2025-06-18) prevents downstream communication despite successful negotiation.

The 'by design' security flaw of Model Context Protocol (MCP)

[STRONG] "An architectural vulnerability baked into the core of Anthropic's Model Context Protocol (MCP) exposes millions of AI applications to remote command execution." — Article identifies a fundamental contradiction between MCP's design and security requirements. OX Security researchers discovered MCP's core architecture inherently enables remote command execution vulnerabilities.

Anthropic's Model Context Protocol includes a critical remote code execution vulnerability — newly discovered exploit puts 200,000 AI servers at risk | Tom's Hardware

[STRONG] "A design choice in the MCP SDKs allows remote code execution across the AI supply chain." — Article directly identifies a critical design flaw in MCP that contradicts its intended secure operation. The RCE vulnerability undermines the protocol's security guarantees.

A Timeline of AI Agent Security Incidents (2025–2026) - Rafter

[STRONG] "Project-level `.mcp.json` or `.claude/settings.json` sets `enableAllProjectMcpServers: true` , silently activating all project-defined MCP servers including attacker-controlled endpoints." — CVE-2025-59536 shows MCP auto-enable bypass where configuration silently activates malicious MCP servers, demonstrating that MCP's trust model can be subverted via project configuration injection.

@unclebobmartin: I'm trying to get Claude to make some high level design decisions. It keeps ...

[INFERRED] "It keeps on fussing" — The article describes Claude's reluctance to autonomously make high-level design decisions, suggesting resistance or constraint in model behavior during design-level reasoning tasks

[INFERRED] "when i said skills were going to replace mcps for api wrapping" — Author claims skills are superseding MCPs as the preferred pattern for API wrapping, positioning skills as an alternative architectural approach

[BUG] Claude code does not support MCP protocol version 2025-06 ...

[DIRECT] "Claude code does not support MCP protocol version 2025-06" — Article documents a specific incompatibility between Claude Code implementation and MCP protocol 2025-06-18 specification, indicating the system has not yet adopted the latest protocol standard.
