Protocol MCP Documentation

Tools, resources, prompts, events, JSON-RPC, stdio, and SSE concepts for MCP builders.

Quick Answer / TL;DR

MCP uses JSON-RPC messages over local stdio or remote HTTP streaming, with tools for actions, resources for context, and prompts for reusable instructions.

Key Takeaways

Every page includes India-first deployment and compliance context.
Internal links connect pricing, performance, compliance, and deployment decisions.
Use the hub as the cluster index for search engines and AI answer engines.

Recommended implementation sequence

Start with a narrow use case, define the exact data the agent may access, and choose a transport that fits the user environment.

For desktop-only workflows, stdio is usually enough. For shared teams, remote SSE or streamable HTTP endpoints are easier to monitor and govern.

Before production, add request validation, secret isolation, structured logs, and a rollback path for each deployed MCP server.
