MCP vs REST API 2026

Compare MCP and REST APIs for AI agents, CRUD apps, discovery, security, performance, and India deployments.

Quick Answer / TL;DR

MCP and REST are complementary. REST is excellent for deterministic application endpoints; MCP is better when AI clients need dynamic discovery, tools, resources, and prompt context.

Key Takeaways

REST remains useful.
MCP sits above APIs for agents.
Use MCP when discovery and model context matter.

Architecture comparison

REST exposes resources through fixed URLs. MCP exposes tool and context capabilities through a protocol that AI clients can discover and call safely.

Need	REST	MCP
CRUD application	Strong	Optional wrapper
AI tool discovery	Custom code needed	Native
Prompt templates	Not standard	Native
Human approval	Application-specific	Client workflow friendly

Example wrapper

Many Indian teams keep REST APIs and expose only selected actions through MCP for agents.

async function getSettlement({ id }) {
  const response = await fetch(`https://api.example.in/settlements/${id}`, {
    headers: { Authorization: `Bearer ${process.env.API_TOKEN}` }
  });
  return response.json();
}
