Frontend process for integrating and managing third-party services using Model Context Protocol (MCP).

​
Overview

MCP provides standardized connections between AI systems and external data sources, storing service data per user for secure access management.

​
Integration Steps

​
1. Environment Setup

  • Configure service environment variables:
    • Client ID
    • Client Secret
  • Set up service configuration:
    • OAuth endpoints
    • Required scopes

​
2. OAuth Flow Implementation

Initiation:
  • User clicks “Connect”
  • Generate OAuth state
  • Redirect to service OAuth URL
Callback Processing:
  • Service redirects with authorization code
  • Frontend exchanges code for access token
  • Verify OAuth state
  • Handle errors and display feedback
Token Storage:
  • Encrypt access token
  • Store with user information in database

​
3. Database Management

Storage Structure: 
mcpdata: {
  SLACK: {},
  GITHUB: {},
  GOOGLE_DRIVE: {}
}
Disconnect Process:
  • Remove specific service token from user collection
  • Update user’s MCP data object

​
4. State Management

Redux Store:
  • Connection status tracking
  • Loading states management
  • MCP data persistence
Secure Storage:
  • Encrypted token storage
  • User service selections
  • Tool configurations per service

​
5. Tool Integration

Service Mapping:
  • Define available tools per service (Slack, GitHub, etc.)
  • Configure UI service selection options
  • Map service codes to tool functionality
Tool Configuration:
  • Service-specific tool settings
  • Parameter requirements per tool
  • Permission management

​
6. Chat Interface Integration

Service Loading:
  • Load connected MCP services on chat page load
  • Display available tools grouped by service
  • Dynamic tool selection interface
Query Processing:
  • User selects tool from available list
  • Collect required parameters via dynamic forms
  • Submit query for tool invocation
  • Display results inline in chat interface

​
7. Disconnect Workflow

User Interface:
  • “Disconnect” button in service configuration modal
  • Confirmation dialog to prevent accidental disconnection
  • User confirmation required
State Updates:
  • Display “Disconnecting…” loading state
  • Disable disconnect button during process
  • Show visual feedback (spinner, progress indicators)
Backend Communication:
  • POST request to backend with:
    • User authentication credentials
    • Target service information
  • Handle API response or error states

​
Security Considerations

  • Token encryption at rest
  • Secure OAuth state validation
  • Protected API endpoints
  • User-specific data isolation

​
