ATLAS-GATE-MCP

Enterprise Model Context Protocol Security Gateway with MCP-Only Sandbox Enforcement

High-Level Overview

ATLAS-GATE-MCP is a production-grade Model Context Protocol (MCP) server that implements enterprise-grade security governance, process-level sandbox enforcement, and comprehensive audit trails for AI agent operations. The system transforms unconstrained AI agents into governed execution authorities through a multi-layered security architecture that enforces zero-trust principles, plan-based authorization, and immutable audit logging.

The system addresses the fundamental security challenge of allowing AI agents to interact with critical systems while maintaining enterprise-grade security posture, compliance requirements, and operational visibility. ATLAS-GATE-MCP serves as a security gateway that mediates all AI agent interactions with development environments, enforcing strict governance policies while providing the flexibility required for modern AI-assisted development workflows.

ATLAS-GATE-MCP operates as an MCP server/gateway in modern AI infrastructure, sitting between AI models/clients and target systems (filesystems, databases, APIs, development tools). It is designed for enterprise environments where security, auditability, and compliance are non-negotiable requirements.

MCP Fundamentals

The Model Context Protocol (MCP) is a standardized protocol for enabling AI models to securely interact with external systems, tools, and data sources. MCP provides a structured framework for AI agent operations that addresses the limitations of traditional integration approaches.

Core Concepts and Terminology

• MCP Server: A process that exposes capabilities to AI models through standardized interfaces. ATLAS-GATE-MCP is an MCP server.
• Tools: Executable functions that AI models can invoke. Tools have defined schemas, parameters, and return values. Examples include file operations, API calls, database queries.
• Resources: Read-only data sources that AI models can access. Resources represent static or dynamic data like configuration files, documentation, or system state.
• Prompts: Reusable prompt templates that guide AI model behavior for specific tasks or contexts.
• Transport Layer: Communication mechanism between AI models and MCP servers, typically JSON-RPC 2.0 over stdio or HTTP.
• Session: A bounded interaction context between an AI model and MCP server with associated state and permissions.

Design Philosophy

MCP exists to solve fundamental architectural problems in AI agent integration:

1. Security Isolation: Prevents AI models from having unrestricted system access
2. Standardization: Provides consistent interfaces across different AI models and tools
3. Governance: Enables policy enforcement and audit trails for AI operations
4. Composability: Allows tools and capabilities to be combined safely
5. Observability: Provides visibility into AI agent operations and decision-making

Compared to traditional APIs, MCP offers:

• Schema Validation: All tool inputs/outputs are validated against defined schemas
• Capability Discovery: AI models can discover available capabilities dynamically
• Security Boundaries: Built-in authentication, authorization, and audit mechanisms
• State Management: Proper session handling and state isolation
• Error Handling: Structured error responses with appropriate context

Compared to plugin-based systems, MCP provides:

• Protocol Standardization: Consistent interface across different implementations
• Security Model: Built-in security considerations rather than afterthought
• Transport Independence: Multiple communication patterns supported
• AI-First Design: Designed specifically for AI model interaction patterns

Security and Permission Model

ATLAS-GATE-MCP implements a comprehensive, defense-in-depth security model designed for enterprise environments where security, compliance, and auditability are paramount.

Authentication Assumptions

ATLAS-GATE-MCP operates under a zero-trust security model with the following authentication assumptions:

Transport Security: Communication occurs over controlled stdio transport or authenticated HTTP channels. The protocol assumes the transport layer provides basic authentication and integrity protection.

Session Authentication: Sessions are established via begin_session with workspace binding and cryptographic session identifiers. Session state is maintained server-side with proper isolation.

Plan-Based Authentication: Operations are authenticated against approved plans stored in the governance repository. Plans serve as capability tokens that authorize specific operations within defined scopes.

Bootstrap Authentication: Initial system setup requires bootstrap secret authentication for creating the first governance plans. This secret is single-use and destroyed after initial configuration.

Authorization and Permission Boundaries

The authorization model implements multiple, overlapping permission boundaries:

Role-Based Authorization:

• Windsurf Role: Full execution capabilities including file writes, plan creation, and system modifications
• Antigravity Role: Read-only capabilities including file reads, plan inspection, and analysis operations
• Role Separation: Strict enforcement prevents privilege escalation between roles

Plan-Based Authorization:

• Plan Reference: All operations must reference an approved plan ID
• Scope Validation: Operations are validated against plan-defined scopes and constraints
• Hash Verification: Plan integrity is verified via cryptographic hashes
• Temporal Validity: Plans may include temporal constraints and expiration

Capability-Based Authorization:

• Tool Scoping: Each tool has defined capabilities and required permissions
• Parameter Validation: Tool parameters are validated against schemas and security policies
• Resource Access: Filesystem and resource access is limited to authorized paths
• Operation Constraints: Specific operations may have additional constraints (e.g., file size limits)

Access Control Mechanisms

MCP-Only Enforcement:

• Process sandbox prevents direct system access
• All operations must go through MCP tool interfaces
• Filesystem access is mediated through authorized tools only
• Network access is blocked by default with explicit allowances

Content Security:

• Static analysis prevents injection of malicious code patterns
• Stub detection prevents deployment of incomplete or placeholder code
• Policy enforcement blocks prohibited constructs and practices
• Content integrity verification ensures file consistency

Audit and Compliance:

• Comprehensive audit logging captures all operations with full context
• Cryptographic signatures ensure audit log integrity
• Tamper detection mechanisms prevent audit log manipulation
• Compliance reporting supports regulatory requirements

Data Exposure and Capability Escalation Prevention

Data Isolation:

• Session-based isolation prevents cross-session data leakage
• Workspace binding limits operations to authorized directories
• Path traversal protection prevents unauthorized file access
• Content filtering prevents sensitive data exposure in responses

Capability Escalation Prevention:

• Role separation prevents read-to-write privilege escalation
• Plan authorization prevents unauthorized capability acquisition
• Tool scoping limits operations to defined boundaries
• Static analysis prevents privilege escalation through code injection

Least Privilege Enforcement:

• Default-deny security posture with explicit authorization
• Minimal required permissions for each operation
• Time-limited authorization tokens where applicable
• Revocation capabilities for compromised sessions or plans

Design Principles

Zero Trust: Never trust, always verify. All operations require explicit authorization regardless of source.

Fail-Secure: Security violations result in operation termination rather than risky fallbacks.

Defense in Depth: Multiple, overlapping security controls ensure no single point of failure.

Audit by Design: All operations are auditable by design with comprehensive logging and integrity protection.

Least Privilege: Operations are granted minimal necessary permissions with scoped access.

Transparency: Security decisions are logged and auditable with clear reasoning and evidence.
