Model Context Protocol
- Hosts are LLM applications (like Claude Desktop or IDEs) that initiate connections
- Clients maintain 1:1 connections with servers, inside the host application
- Servers provide context, tools, and prompts to clients

MCP Usages
Roadmap
- agentic messaging primitives
- HTTP-native transport unification and hardening
- agent identity / enterprise-ready security
- improved primitives
- improved SDK developer experience

Limitation
The structure requiring code execution from users poses security risks and is vulnerable to malicious inputs. There are authentication issues and no restrictions on dangerous tools. It's difficult to implement interactive UX and is vulnerable to AI Hacking techniques like Prompt Injection.

Introducing the Model Context Protocol
The Model Context Protocol (MCP) is an open standard for connecting AI assistants to the systems where data lives, including content repositories, business tools, and development environments. Its aim is to help frontier models produce better, more relevant responses.

What it means compared to, Network API
Glama – MCP Hosting Platform
MCP is a wire protocol that standardizes how AI agents interact with external services, enforcing single JSON schemas and deterministic execution, while traditional APIs are documentation formats describing the chaos of HTTP endpoints where data can live in paths, headers, query params, or bodies.

MCP servers: the context-token cost, measured per server · Okane Land
We measured the tool-definition token cost of ten popular MCP servers, and when that cost hits in current Claude Code. Per-server table, keep-or-cut verdicts.
