Step 1: Understand the Structure of MCP
To build a context prioritization engine for MCP packing, it's crucial first to understand the structure of the Model Context Protocol (MCP). MCP comprises several components that define:
You need to structure these components in a standardized way to dictate how an LLM should act.
Step 2: Design the MCP Schema
Create a schema for MCP to define how context data should be organized and parsed. This might look like a JSON structure:
{
"system_instructions": "You are a helpful assistant specialized in finance.",
"user_profile": {
"name": "John",
"preferences": {
"language": "English",
"formality": "Casual"
},
"goals": ["Save money", "Understand stocks"]
},
"document_context": ["User uploaded financial report 2023", "Recent market analysis"],
"active_tasks": ["Advise on stock portfolio", "Create budget plan"],
"tool_access": ["web", "Python", "database"],
"rules_constraints": ["Do not provide legal advice", "Avoid medical suggestions"]
}
This schema provides a blueprint for arranging and transmitting context data to the LLM.
Step 3: Build the Context Prioritization Logic
Develop an algorithm for prioritizing which pieces of context should be active and relevant at any given time. Consider criteria such as:
You could use a simple prioritization algorithm, such as:
def prioritize_context(contexts):
# Sort contexts based on custom criteria
prioritized_contexts = sorted(contexts, key=lambda ctx: (ctx.get('recency', 0), ctx.get('relevance', 0)), reverse=True)
return prioritized_contexts
This function can be adjusted to suit specific prioritization needs by including more sophisticated logic as necessary.
Step 4: Implement MCP Packing
Incorporate the MCP packing process into your system. This involves taking prioritized context and generating a structured packet that is passed to the LLM. You might use functions to serialize the prioritized context into JSON format:
def packmcp(prioritizedcontexts):
mcp_packet = {
"system_instructions": "You are a helpful assistant specialized in finance.",
"userprofile": prioritizedcontexts.get('user_profile', {}),
"documentcontext": prioritizedcontexts.get('document_context', []),
"activetasks": prioritizedcontexts.get('active_tasks', []),
"toolaccess": prioritizedcontexts.get('tool_access', []),
"rulesconstraints": prioritizedcontexts.get('rules_constraints', []),
}
return json.dumps(mcp_packet)
This code efficiently packages the MCP data into the desired format for transmission to the model.
Step 5: Test the System
Once the context prioritization engine is built, it's important to thoroughly test its effectiveness. Simulate various user scenarios and evaluate whether the context prioritization correctly identifies relevant components and if the LLM responds as expected.
Through comprehensive testing, you can ensure the MCP packing efficiently guides the LLM behavior.
