working with agents — and building them.
Let an agent change which MCP servers are enabled mid-session — list the MCPs, restart, and continue.
I had agents connected to ~37 of my integrations and apps, and honestly the time-to-first-token was too slow with everything loaded up front.
So instead of carrying all of it, I blow the agent away — kill the session, instant-reconnect, and specify only the tools it actually needs. A hook lists the available MCP servers and re-enables just the relevant ones on continue.
