MCP Server
The Universal Connector for AI Agents
Quick Answer / TL;DR
An MCP server is a JSON-RPC 2.0 service that exposes tools, resources, and prompts to AI clients, enabling dynamic integration without custom code.
Key Takeaways
- Standardized JSON-RPC 2.0 communication format
- Compatible with Claude Desktop, Cursor, and other MCP-speaking clients
- Replaces one-off API integrations with a single client-server interface
Key Compliance Rule: Under the DPDP Act 2023, MCP servers processing Indian user data must enforce data localization and maintain immutable audit logs.
2. How It Works
Complete guide to Model Context Protocol servers – architecture, transport, security, and deployment.
Client Discovery
Client queries the local/remote MCP server capabilities via standard JSON-RPC handshake.
Schema Mapping
Exposed resources, tools, and templates are dynamically validated against standardized schemas.
3. When to Use It
This standard protocol should be implemented whenever an application requires:
- Real-time database queries prompted dynamically by user conversations.
- Secure interaction with private enterprise repositories (GitHub, GitLab).
- Dynamic tool call structures that avoid hardcoded server routes.
4. Connection Architecture
Standard Protocol Stack Flow
- Transport Protocol: Configurable Stdio pipeline or Server-Sent Events (SSE).
- RPC Layer: 100% compliant JSON-RPC 2.0 message parsing.
- Validation Layer: Strict JSON-Schema constraints check for error-free queries.
5. Standard Setup Instructions
# Install the official MCP SDK
npm install @modelcontextprotocol/sdk
# Configure server inside Claude Desktop config
{ "mcpServers": { "my-server": { "command": "node", "args": ["dist/index.js"] } } }
6. Security & Isolation Controls
Because MCP servers run locally or inside hosted cloud environments, they have direct code execution abilities. Always constrain environments, rotate keys, use secure SSE paths, and authorize write operations.
7. Engineering Best Practices
Keep Schemas Minimal
Avoid deeply nested structures so LLMs can map parameters accurately.
Stderr Logging
Always log debugging outputs to stderr, keeping stdout clean for JSON-RPC messages.
Supported Integrations
GitHub
Securely connect your AI agents to private and public GitHub repositories to write, review, and automate code workflows, pull requests, issues, and releases.
PostgreSQL
Expose PostgreSQL databases to AI agents. Let your models query schemas, run safely-isolated SELECT queries, and automate database administration tasks.
Slack
Let AI agents read public channels, send instant Slack updates, search for historical threads, and manage channel setups.
Deploy Node Globally
Deploy ultra-low latency Model Context Protocol nodes to Mumbai / Bengaluru edge clusters with zero DevOps management.
