Notes from building the gateway
What we have learned about MCP, credential design, tool retrieval and the arithmetic that catches every agent team eventually.
The N×M problem is eating agent teams alive
Every agent needs tools; every tool needs an integration. The arithmetic gets ugly fast, and a gateway is the only shape that fixes it.
Stop putting API keys in your agents
Handing provider credentials to an autonomous process is a blast radius problem. Scoped, revocable, brokered access is the fix.
How tool discovery keeps 25,000 tools out of your context window
A catalog this size cannot be pasted into a prompt. Here is the retrieval layer that decides what an agent actually sees.
Turning any REST API into an MCP server
Most of an MCP server is mechanical translation from a schema you already have. Here is what generates cleanly and what still needs a human.
Give every agent one endpoint
Connect your apps once, mint a scoped key, and point Claude, Codex, Cursor or your own runtime at a single MCP server.
