Overview
- MCP is an open standard that lets AI apps connect to files, APIs, databases, and workflows so one model can call many approved tools through a single, consistent layer.
- Anthropic launched the protocol in 2024, and support from OpenAI documentation and Linux Foundation stewardship has helped push it into wider use across the industry.
- Recent security research reported flaws in MCP SDK behavior and in some servers that created paths for remote code execution and supply‑chain style attacks, according to coverage that cited OX Security and Tom's Hardware.
- Bugs in Anthropic’s Git MCP server were fixed after disclosure, reinforcing that teams must add strong authentication, permission checks, and logging rather than assuming the standard makes tool use safe by default.
- Experts recommend adopting MCP when it clearly cuts repeated integration work for apps that need shared tool access and live data, and avoiding it when simpler direct APIs meet the product’s needs.
