How to assign trust levels or verification states inside MCP?

 

Step 1: Understand the Components of MCP

 

• Familiarize yourself with the core components of the Model Context Protocol (MCP), which include System Instructions, User Profile, Document Context, Active Tasks/Goals, Tool Access, and Rules/Constraints. Understanding these will provide a foundation for assigning trust levels or verification states.

 

Step 2: Define Trust Levels or Verification States

 

• Decide on the specific trust levels or verification states you wish to implement for your application. Examples might include trusted, verified, unverified, or restricted. These will help in setting boundaries on how the model can access or interpret different contexts.

 

Step 3: Integrate Trust Levels within System Instructions

 

• Modify the System Instructions to incorporate trust levels. This can be done by embedding rules within the instructions.

System_Instructions = {
    "role": "You are an LLM functioning as an assistant with different access levels.",
    "trust_levels": {
        "trusted": "Full access to tools and data.",
        "verified": "Limited access, with some restrictions.",
        "unverified": "Minimal access, review required before processing."
    }
}

 

Step 4: Incorporate Trust Levels into User Profiles

 

• Embed trust information into the User Profile to ensure the model acknowledges user-specific permissions.

User_Profile = {
    "name": "John Doe",
    "preferences": ["financial analysis", "real-time updates"],
    "trust_level": "verified"
}

 

Step 5: Utilize Trust Levels in Document Context

 

• When adding documents or knowledge bases, assign them a trust level to guide the model's access.

Document_Context = {
    "FinancialReport2023": {
        "content": "",
        "trust_level": "trusted"
    },
    "UserGeneratedContent": {
        "content": "",
        "trust_level": "unverified"
    }
}

 

Step 6: Define Trust Levels in Active Tasks/Goals

 

• Set tasks with respective trust levels to ensure goals are aligned with permitted access.

Active_Tasks = {
    "task_1": {
        "objective": "Generate quarterly report",
        "trust_level": "trusted"
    },
    "task_2": {
        "objective": "Analyze user feedback",
        "trust_level": "verified"
    }
}

 

Step 7: Apply Trust Levels to Tool Access

 

• Define which tools a model can or cannot call based on trust levels. Restrict or allow access as necessary.

Tool_Access = {
    "trusted_tools": ["database", "web scraper"],
    "verified_tools": ["basic analytics", "summarization"],
    "restricted_tools": ["social media API", "email sender"]
}

 

Step 8: Implement Rules/Constraints with Trust Levels

 

• Add constraints that enforce the permissible actions for each trust level, ensuring compliance with defined boundaries.

Rules_Constraints = {
    "trusted": "Can access sensitive data and perform data modification.",
    "verified": "Can only read sensitive data, no modification allowed.",
    "unverified": "Cannot access sensitive data."
}

 

Step 9: Test the System for Compliance and Security

 

• Validate the system by testing scenarios with different trust levels to ensure that the model adheres to the set rules and properly assigns verification states.

 

Step 10: Iterate and Update Trust Levels

 

• Continuously monitor and refine trust levels and verification states according to changes in use cases or security requirements to maintain an effective context management system.
