Taking MCP Further: Runebook is Joining Keycard

When we set out to build Tome, we started with a simple belief: powerful tools should feel effortless. LLMs were getting better at an incredible pace, but connecting them to real products and systems still felt too complicated. If we wanted LLMs to be truly useful, we needed to make the surrounding ecosystem dramatically easier to work with.

That idea shaped how we approached MCP. When MCP arrived most people were juggling npm, uv, and JSON config files just to experiment. So we built the client we wished existed. Tome launched in April and gave anyone the ability to connect to an LLM, local or remote, and one-click install MCP servers from Smithery without touching a single configuration file. We wanted the easiest possible entry point into the MCP world, and for many people Tome became exactly that. (People even used Tome to learn how to build an MCP Server!)

Over the months that followed, it became clear that installation was only the first hurdle. As teams explored serious MCP adoption, the real challenges surfaced. Giving servers the right level of access without overexposure. Deploying agents across environments beyond a single laptop. Delivering tools to end users in a way that’s safe, reliable, and production-ready. These aren’t small UX issues, they’re deep infrastructure problems that need a dedicated platform behind them, one that doesn’t compromise on security or developer experience.

That’s why connecting with the Keycard founders was such an aha moment for us. We were working toward the same goal from different directions. We wanted to make LLM tool integrations simple and accessible. They were building the foundation to make those same integrations secure and trustworthy at scale. Joining forces was a way to bring the original Tome vision to a much larger stage.

So today, I’m excited to share that Runebook is joining Keycard. Together we’ll push forward the mission of building the trust fabric for the agent-native era and make working with MCP as simple and safe as we imagined when we first started building Tome.

Tome will continue to be maintained, and it will remain one of the easiest ways to explore MCP. But our primary focus will shift to helping Keycard become the go-to platform for secure and trusted agent access. We want connecting MCP servers to your agents to feel both powerful and effortless, whether you’re a single developer or a large company rolling out agents across your entire stack.

This is a meaningful new chapter for us, and we’re thrilled about what it unlocks - stay tuned and follow us at our new home, Keycard.ai!
