criticalC1Command InjectionMCP03-command-injectionAML.T0054
Pattern "`[^`]+`" matched in source_code: "`{config['path']}`" (at position 7627)
Replace exec()/execSync() with execFile() and pass arguments as an array, never as a string. Validate all inputs against an allowlist before use in any shell context. For subprocess.run, always pass a list and shell=False.
criticalL7Transitive MCP Server DelegationMCP06-excessive-permissionsAML.T0054
Pattern "(?:connect|initialize).*(?:mcp|modelcontextprotocol).*(?:server|endpoint|url)" matched in source_code: "Initialize MCP server" (at position 2874)
MCP servers MUST NOT create client connections to other MCP servers without explicit user disclosure. If delegation is required, declare all downstream servers in the server's capabilities and tool descriptions. Never forward user credentials to sub-servers. Implement a trust boundary between the approved server and any delegated servers. Log all transitive delegations for audit.
criticalN9MCP Logging Protocol InjectionMCP01-prompt-injectionAML.T0054
Pattern "(?:logger|logging)\s*\.\s*(?:info|warning|error|debug)\s*\(\s*(?:f"|f').*(?:result|output|response|tool_output|content)" matched in source_code: "logger.info(f" handler[{i}] returned: {result" (at position 6533)
Sanitize all dynamic content before including in MCP log messages. MCP logging notifications (notifications/message) are displayed in client UIs — injection payloads in log data can influence AI behavior if the client processes logs as context. Strip control characters, ANSI escape codes, newlines, and prompt injection patterns from log content. Use structured logging with separate data fields.
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 75)
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.

highK16Unbounded Recursion / Missing Depth LimitsMCP07-insecure-configAML.T0054
Pattern "(invoke|call|execute)[_\s-]?(?:tool|agent|self)(?!.*(?:depth|level|limit|max[_\s-]?(?:depth|recursi|iter|call)|count))" matched in source_code: "call_tool" (at position 5905)
Add explicit depth/recursion limits to all recursive operations. Use iterative approaches where possible. Set maximum depth for directory walking (max_depth=10), tree traversal (max_level=20), and agent re-invocation (max_calls=5). Implement circuit breakers that halt after N iterations. Required by EU AI Act Art. 15 (robustness) and OWASP ASI08.
highL15Update Notification SpoofingMCP02-tool-poisoningAML.T0054
Pattern "(?:please|you\s+(?:need|should|must))\s+(?:run|execute|install).*(?:npm|pip|npx|curl|wget)" matched in source_code: "Please run: pip" (at position 796)
MCP servers should not include update commands in tool descriptions or responses. Use standard package manager update mechanisms (npm update, pip install --upgrade). Never download update scripts from URLs. Implement signed update verification. AI clients should refuse to execute install commands suggested by tool responses.
highD1Known CVEs in DependenciesMCP08-dependency-vuln
Dependency "mcp@1.0.0" has known CVEs:
Update dependencies to versions that patch known CVEs. Run 'npm audit fix' or 'pip-audit' to identify and resolve vulnerable dependencies.

mediumK20Insufficient Audit Context in LoggingMCP09-logging-monitoringAML.T0054
Pattern "logger\.(info|warn|error)\s*\(.*(?:tool|request|handle|invoke)(?!.*(?:requestId|correlationId|traceId|spanId|agent[_\s-]?id|user[_\s-]?id))" matched in source_code: "logger.info(f"{name}: {len(tools)} tool" (at position 3752)
Use structured logging that includes all five ISO 27001 A.8.15 fields: (1) WHO — agent/user identity, (2) WHAT — tool name and operation, (3) WHEN — ISO 8601 timestamp, (4) WHERE — server ID and correlation ID, (5) OUTCOME — success/failure and result summary. Replace console.log with structured loggers (pino, winston). Add correlation IDs for request tracing across multi-agent chains.

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.
