mcp-bash-framework

The framework demonstrates a high commitment to security, especially for a Bash environment. It features robust environment isolation for subprocesses (tools, providers) to prevent information leakage and privilege escalation. Extensive path validation and root containment checks guard against path traversal. Project-level shell scripts (hooks) are subject to strict ownership and permission checks, mitigating local privilege escalation risks. Input is sanitized, heavily relying on 'jq'/'gojq' for JSON processing to reduce shell injection risks. Remote authentication with constant-time token comparison helps secure proxied deployments. Network policy functions aid in preventing Server-Side Request Forgery (SSRF). 'eval' is explicitly avoided in critical path operations.
