INSIGHT

MCP Enables Extensible AI Apps

MCP is an open protocol designed to extend AI applications through external integrations by any developer, not just original teams.
It aims to create an interoperable ecosystem for LLM interactions, similar to how APIs unify web service usage.

INSIGHT

Standard Interface for LLM Agents

MCP provides a standard interface for LLM agents to interact with unknown tools or context via a unified protocol.
This approach lets developers build reusable servers, avoiding building a unique tool for every client or platform.

ANECDOTE

MCP's Origin Story

David Soria Parra and Justin Spahr-Summers created MCP inspired by a need to unify workflows across AI tools like Claude Desktop and Zed editor.
They prototyped a Chrome control server (Puppeteer) to power interactive demos showing agents doing tasks autonomously.

In this episode of AI + a16z, Anthropic's David Soria Parra — who created MCP (Model Context Protocol) along with Justin Spahr-Summers — sits down with a16z's Yoko Li to discuss the project's inception, exciting use cases for connecting LLMs to external sources, and what's coming next for the project. If you're unfamiliar with the wildly popular MCP project, this edited passage from their discussion is a great starting point to learn:

David: "MCP tries to enable building AI applications in such a way that they can be extended by everyone else that is not part of the original development team through these MCP servers, and really bring the workflows you care about, the things you want to do, to these AI applications. It's a protocol that just defines how whatever you are building as a developer for that integration piece, and that AI application, talk to each other.

"It's a very boring specification, but what it enables is hopefully ... something that looks like the current API ecosystem, but for LLM interactions."

Yoko: "I really love the analogy with the API ecosystem, because they give people a mental model of how the ecosystem evolves ... Before, you may have needed a different spec to query Salesforce versus query HubSpot. Now you can use similarly defined API schema to do that.

"And then when I saw MCP earlier in the year, it was very interesting in that it almost felt like a standard interface for the agent to interface with LLMs. It's like, 'What are the set of things that the agent wants to execute on that it has never seen before? What kind of context does it need to make these things happen?' When I tried it out, it was just super powerful and I no longer have to build one tool per client. I now can build just one MCP server, for example, for sending emails, and I use it for everything on Cursor, on Claude Desktop, on Goose."
