Why MCP actually matters (in plain English)

MCP is the hottest protocol in the AI market right now.

BEFORE:

Every API connection is a custom job.

• Want your chatbot to check Gmail? Write custom code.

• Want it to also post to Slack? Write MORE custom code.

• Need it to check your calendar too? Yet another integration.

Each new connection = weeks of developer work that breaks when anything changes.

AFTER:

The protocol that turns your AI into an integration expert.

• Your AI connects to Gmail MCP once and is an expert

• Your AI connects to Slack MCP and understands it perfectly

• Your AI connects to your file system once via MCP and knows it inside out

Now your AI can use ALL of them without additional code.

This saves effort on a single integration, but it makes chaining together integrations 100x simpler.

This is the real magic: CONTEXT PRESERVATION.

When your AI jumps from checking your email to updating your calendar, it remembers what it was doing and why.

Receive an invoice? Ping someone on Slack for approval, and then make a payment via a Stripe virtual card.

All of this was possible before MCP, but it was incredibly labor-intensive and would break.

PRACTICAL IMPACT:

• Every new MCP-compatible tool works instantly with your existing stack

• Developers build new features instead of maintaining brittle connections

• Your AI can actually follow complex instructions across multiple systems

As of now, its unclear if MCP or simple tool use (like Open AI is pushing) will become the default.

But MCP has attention because its open source.

It's not always the best protocol that wins, but the one with the most mindshare.
