For Anthropic's Claude Code creator, MCP is the default way to plug an agent into your existing stack — one connector shared across every surface.
for us, it's always just the simplest answer, it's just MCP
MCP vs API is a false dichotomy — what matters is giving the model programmatic access, because everything reduces to tokens anyway.
it could be MCP, CLIs, APIs, just some sort of programmatic access because the … model doesn't care. It's … to the model, it's just tokens
Anthropic's own agent builders warn against reaching for MCP first — an unmanaged pile of overlapping servers creates chaos.
We see a lot of folks run towards MCP first, and a lot of our customers end up in this ecosystem where there's a lot of kind of chaotic MCP servers that exist

The rule of thumb for when to publish an MCP server: only when multiple clients need the same standardized, governed tools.
only in the case where we have a common collection of tools that multiple clients will benefit from accessing, do we go about the process of collecting those and publishing them as an MCP server

In practice, a single MCP connector can stand in for thousands of individual integrations — Gmail, Slack, Notion and beyond.
they allow you to have one connector, one MCP, essentially, that connects to thousands of other apps, whether it's Gmail, Slack, Notion, what have you

Inside the agent loop, MCP is where external tools enter: the model decides what to run and pulls capabilities in from connected servers.
there's the core agent loop itself, where you have Claude model that's determining what to do, what tools to run … maybe it's pulling in some tools from MCP servers

FAQ
What is an MCP server?
An MCP server is a program that exposes tools and data over the Model Context Protocol, an open standard from Anthropic, so AI assistants like Claude can discover and call them. One server can serve many clients at once — the Claude app, Claude Code, and custom agents all reuse the same connector.
What's the difference between MCP and an API?
An API is specific to one service; MCP standardizes how an AI model discovers and calls tools across any service. As Claude Code creator Boris Cherny puts it, to the model it's all just tokens — but builders on the Claude podcast caution that MCP servers can pollute the model's context, so they start with local tools and publish an MCP server only when multiple clients need the same set.
How do I connect an MCP server to Claude?
In the Claude apps, add the server's URL under Settings > Connectors. In Claude Code, run `claude mcp add` with the server command or URL. Once connected, the server's tools are automatically discovered and available to the model in every conversation.
