角色特定上下文 MCP 服务器

Role-Specific Context MCP Server

A Model Context Protocol (MCP) server that defines and governs contextual boundaries based on agent roles in your system.

Overview

This MCP server enables role-based context management for AI agents, allowing you to:

Establish clear instructions, objectives, and domain knowledge for each AI agent (Marketing Expert, Songwriter, Executive Assistant, etc.)
Keep role-relevant memory partitioned and scoped, preventing cross-contamination between different agent roles
Adapt tone and style dynamically (serious, witty, sarcastic) per role, with tone profiles baked into the prompt

Features

Role Management

Create, update, and delete custom roles
Pre-defined roles with specific expertise domains
Role-specific system prompts and instructions
Customizable tone profiles

Memory Management

Role-specific memory storage
Memory retrieval based on relevance to current query
Time-to-live (TTL) for memories
Memory limits per role

MCP Integration

Exposes roles as MCP resources
Provides tools for role management and query processing
Offers prompts for role-based interactions

Getting Started

Prerequisites

Node.js 18+
OpenAI API key

Installation

# Clone the repository
git clone https://github.com/yourusername/role-context-mcp.git
cd role-context-mcp

# Install dependencies
npm install

# Set up environment variables
echo "OPENAI_API_KEY=your_api_key_here" > .env

# Build the project
npm run build

Running the Server

# Run the MCP server
npm start

# Run the HTTP server for testing
npm run start:http

Configuration

The server can be configured by modifying src/config.ts. Key configuration options include:

Default roles and their properties
Available tone profiles
Memory management settings
OpenAI model selection

MCP Integration

Resources

The server exposes the following resources:

role://{roleId} - Information about a specific role
role://tones - Available tone profiles

Tools

The server provides the following tools:

process-with-role - Process a query using a specific role
create-role - Create a new role
update-role - Update an existing role
delete-role - Delete a custom role
change-role-tone - Change the tone of a role
store-memory - Store a memory for a specific role
clear-role-memories - Clear all memories for a role

Prompts

The server provides the following prompts:

role-{roleId} - Use a specific role to process a request
create-custom-role - Create a new custom role

Example Usage

Processing a Query with a Role (MCP)

// Example of using the process-with-role tool
const result = await client.executeToolRequest({
  name: 'process-with-role',
  parameters: {
    roleId: 'marketing-expert',
    query: 'How can I improve my social media engagement?',
    customInstructions: 'Focus on B2B strategies'
  }
});

Processing a Query with a Role (HTTP API)

// Example of using the HTTP API
const response = await axios.post('http://localhost:3000/process', {
  roleId: 'marketing-expert',
  query: 'How can I improve my social media engagement?',
  customInstructions: 'Focus on B2B strategies'
});

console.log(response.data.response);

Creating a Custom Role

// Example of using the create-role tool
const result = await client.executeToolRequest({
  name: 'create-role',
  parameters: {
    id: 'tech-writer',
    name: 'Technical Writer',
    description: 'Specializes in clear, concise technical documentation',
    instructions: 'Create documentation that is accessible to both technical and non-technical audiences',
    domains: ['technical-writing', 'documentation', 'tutorials'],
    tone: 'technical',
    systemPrompt: 'You are an experienced technical writer with expertise in creating clear, concise documentation for complex systems.'
  }
});
