Model Context Protocol (MCP)
Verdict
The open standard connecting AI assistants to tools and internal data — now the default integration layer.
Where it wins, where it doesn't
Pros
- Universal stateless bridge between assistants and internal tools
- Robust OAuth support when configured properly
- Keeps data on your infrastructure rather than in a provider's
Cons
- A malicious or compromised server is a supply-chain risk with an execution path
- Secure initial setup is genuinely complex
- Server quality across the ecosystem varies enormously
Editorial note
MCP won the integration problem by being boring in the right way: a stateless protocol that lets any assistant talk to any tool without either side knowing about the other in advance. That is why it went from proposal to de facto standard so quickly, and why the interesting question is no longer whether to use it but how to secure it. The security surface is genuine and under-appreciated. An MCP server is, by design, something an AI can invoke, which means a compromised or malicious server is a compromised or malicious action taken on your behalf — supply-chain risk with an execution path attached. OAuth support is solid and worth using properly rather than reaching for a static token. Treat server selection with the same scrutiny you would give a dependency with production credentials, because that is what it is.
In-Depth Review
MCP won the integration problem by being boring in the right way: a stateless protocol that lets any assistant talk to any tool without either side knowing about the other in advance. That is why it went from proposal to de facto standard so quickly.
Why it matters
- One bridge, many tools. You implement a server once and every MCP-compliant assistant can use it.
- Data stays put. The tool runs on your infrastructure; the provider never holds your internal data.
- OAuth support is solid when configured properly — reach for it rather than a static token.
The security surface is real and under-appreciated
An MCP server is, by design, something an AI can invoke — so a compromised or malicious server is a malicious action taken on your behalf. Supply-chain risk with an execution path attached. Server quality across the ecosystem varies enormously, and secure initial setup is genuinely complex.
The rule
Treat server selection with the scrutiny you would give a dependency holding production credentials, because that is what it is. Vet the source, pin versions, and scope permissions tightly.
