• Today I learned that @OpenAIDevs MCP client https://t.co/nhRPF6KVEf lists private_key_jwt for the token endpoint auth while the CIMD endpoint is actually public (auth=none). So your MCP OAuth must be able to skip private_key_jwt, if unsupported.

• Even if an AI did exactly what I told it to do, precisely and without error, I would still work hard as an engineer. Brooks told us why in 1986: "Even perfect program verification can only establish that a program meets its specification. Much of the essence of building a program is in fact the debugging of the specification." What he meant is that engineering is not the execution of commands... It is very much design. And design is ridiculously difficult. You need to decide what you will build and how you will build it. Of course, you can outsource the design to the AI. But that's assuming t…

• Goodbye per-seat pricing. Per-user pricing has always rubbed me the wrong way. And in this agentic age, it feels downright antique. For the vast majority of the time Basecamp has been on offer, we never charged per-user. A few years ago we experimented with one pay-per-user plan, and that experiment just came to an end. And it couldn’t come at a better time. With the Basecamp CLI (and soon MCP, too), you can bring your agents to Basecamp as users too. Charging you for individual agents feels just as wrong as charging you for individual people. So today we have brand new pricing plans with NO…
