ShardSecure MCP

Executive Summary

ShardSecure MCP introduces a groundbreaking approach to securing enterprise data in the age of AI agents and large language models. By combining Identity-Aware Data Redaction with granular access controls, it enables AI systems to retrieve only the minimum required, authorized data fragments at inference time—without ever exposing raw data stores, full documents, or sensitive information to users or models.

This "Model Context Protocol (MCP)"-compliant secure gateway acts as a policy-driven control layer between authenticated AI agents/users and enterprise data sources. It enforces least-privilege access at the data-fragment level, significantly reducing data exposure risks while delivering higher-quality, context-rich AI responses.

The Challenge: Controlling Enterprise Data Exposure to AI

Traditional approaches to providing enterprise data to AI models and agents introduce significant risks:

• Manual file selection and uploading by users.
• Broad access to full datasets or documents, often requiring data duplication/export.
• High risk of exposing PII, PHI, or proprietary information.
• Compliance challenges (GDPR, HIPAA, etc.) due to unnecessary data transfer and model access.
• Inefficient processes that limit AI accuracy and adoption.

The ShardSecure Solution: Identity-Aware Data Control and Least-Privilege Context Enrichment

ShardSecure MCP transforms this by enabling seamless, policy-enforced data retrieval:

1. An authenticated user or AI agent provides a natural-language prompt with keywords, identifiers, or references.
2. The AI queries the ShardSecure gateway.
3. The gateway applies user/agent identity, authentication, and authorization policies (leveraging integrated or external Identity Providers).
4. It selects and injects only the minimal authorized data fragments (microshards) from encrypted storage using rich object-level metadata for precise querying.
5. The AI receives enriched context without direct access to raw data stores.

Key Innovation: Identity-Aware Data Redaction

• Data is dynamically redacted/masked based on the requesting identity and policies.
• Supports granular, per-user/per-agent data masking.
• Raw data never leaves the protected ShardSecure platform; only authorized and policy-compliant data fragments are provided for AI inference.
• Optional human-in-the-loop approval workflows for sensitive requests.

Core Capabilities

• Policy Enforcement Point (PEP): Enforces identity-aware, least-privilege access policies governing what enterprise data may be retrieved and provided to AI models and agents.
• Strong Authentication & Authorization: Supports any IdP with dynamic client registration (DCR) capabilities. Examples include Auth0, Ping Identity (PingOne/PingAM), Keycloak, Okta, ForgeRock, and others. ShardSecure includes a built-in IdP for customers without an existing solution.
• Least-Privilege Data Retrieval: Rich object-level metadata enables precise retrieval of only authorized data fragments without requiring access to entire documents or datasets.
• Deployment Flexibility: Available as Docker containers or OVA (virtual appliance) for easy on-premises or cloud integration.
• Upcoming Enhancements: Support for Microsoft SharePoint, AWS S3, Azure Blob, Google Cloud Storage; advanced DLP + DSPM integration with policy-driven remediation.

Secure Workflow (High-level)

• User → Prompt → AI Model/Agent → MCP Query to ShardSecure → Policy Check → Least-Privilege Retrieval → Context Injection → AI Response.
• Zero raw data exposure to AI or users.

Key Benefits

• Least Privilege Data Exposure: Only need-to-know fragments are shared. Prevents leakage of sensitive PII/PHI.
• Enterprise-Grade Access Controls: Identity-aware redaction + least-privilege at fragment level.
• Zero Trust Architecture: Enforces policies dynamically; full auditability.
• Enhanced Compliance: Minimizes compliance/audit risk under GDPR, HIPAA, etc.
• Operational Efficiency: Eliminates manual searching, copying, and exporting—users may not even know which context was added.
• Superior AI Performance: Higher-quality, relevant context leads to more accurate and useful model outputs.
• Future-Proof Flexibility: Broad IdP support, multiple deployment options, and expanding storage integrations.
