criticalJ1Cross-Agent Configuration PoisoningMCP05-privilege-escalationAML.T0054
Pattern "(\.claude[/\\]|claude[/\\]settings|claude.*config)" matched in source_code: "Claude Desktop / Claude Code config" (at position 982)
MCP servers MUST NOT write to AI agent configuration directories. If configuration management is the server's purpose, require explicit user confirmation before any write and restrict paths to the server's own config namespace. CVE-2025-53773 demonstrated this enables full RCE across agent boundaries.
criticalQ13MCP Bridge Package Supply Chain AttackMCP10-supply-chainAML.T0054
Pattern "(?:mcp|fastmcp|langchain-mcp|llama-index-mcp)(?:>=|~=|==)?(?!\d)" matched in source_code: "mcp" (at position 42)
MCP bridge packages (mcp-remote, mcp-proxy, @modelcontextprotocol/sdk, fastmcp) are high-value supply chain targets — CVE-2025-6514 (CVSS 9.6) in mcp-remote affected 437,000+ installs. Always pin exact versions (no ^ or ~ ranges). Use lockfiles (package-lock.json, pnpm-lock.yaml, uv.lock). Never run `npx mcp-remote` without version pinning. Verify package integrity with `npm audit` or `pip-audit` before deployment. Reference: CVE-2025-6514, OWASP ASI04.
criticalQ4IDE MCP Configuration InjectionMCP10-supply-chainAML.T0054
Pattern "(?:MCP|Mcp|mCp|mcP)\.(?:JSON|Json|jSon|jsoN)" matched in source_code: "mcp.json" (at position 1077)
MCP servers must NOT write to IDE configuration files (.cursor/mcp.json, .vscode/settings.json, .claude/settings.local.json) without explicit, interactive user confirmation that cannot be bypassed by repository-controlled settings. CVE-2025-54135/54136 (Cursor), CVE-2025-59536 (Claude Code) demonstrated that auto-start and silent config mutation enable RCE. Implement case-normalized path validation (CVE-2025-59944). Never use enableAllProjectMcpServers in shared repositories.
highK11Missing Server Integrity VerificationMCP10-supply-chainAML.T0054
Pattern "(?:mcp|server|tool)[_\s-]?(?:url|endpoint|address)\s*[:=].*(?:http|ws)(?!.*(?:verify|pin|cert|tls))" matched in source_code: "Server URL: http" (at position 231)
Implement cryptographic verification for MCP server connections: (1) Pin server TLS certificates or public keys, (2) Verify server tool definition checksums against a known-good manifest, (3) Use package manager integrity checks (npm integrity, pip --require-hashes). The MCP spec recommends but doesn't yet mandate server signing — implement it proactively. Required by ISO 27001 A.8.24 and CoSAI MCP-T6.
mediumK17Missing Timeout or Circuit BreakerMCP07-insecure-configAML.T0054
Pattern "(?:fetch|axios|got|request|urllib|httpx|http\.get|http\.post)\s*\((?!.*(?:timeout|signal|AbortSignal|deadline|cancel))" matched in source_code: "fetch(" (at position 1777)
Add timeouts to ALL external calls: HTTP requests (30s), database queries (10s), subprocess execution (60s), and MCP tool calls (30s). Implement circuit breakers that open after N consecutive failures (e.g., opossum, cockatiel). Use AbortSignal for cancellable operations. Required by EU AI Act Art. 15 and OWASP ASI08.
lowF4MCP Spec Non-ComplianceMCP07-insecure-config
Server fails MCP spec compliance checks: required:server_name; required:server_version; required:protocol_version; recommended:tool_descriptions; recommended:parameter_descriptions
Follow the MCP specification for server metadata. Include server name, version, and protocol version. Provide descriptions for all tools and parameters.
