Wiring an agent framework to an MCP server is the easy half, the part that broke for me was evaluating the handoffs once the agent started calling those tools in sequence. I wrote up the handoff checks I run here: kartiknvjk.hashnode.dev/how-i-evaluate-agent-hand…, since a clean integration still fails if the agent passes the wrong context between steps. Useful walkthrough for getting the Fabric MCP piece connected in the first place.
