network automation

Part 7 of the Agentic NOC series. How you earn the right to trust a system that watches and sometimes changes your network: 131 offline tests against real captured output, mutated-data fault detection, a live 30-fault campaign, and the worst bug of all, a monitor that mistakes silence for success.

Part 6 of the Agentic NOC series. Real captured runs: a request crossing both protocol layers to a live switch, the planner fanning out, a 30-fault detect-remediate-verify loop, the monitor self-healing then escalating on a flap and refusing to fake health.

Part 5 of the Agentic NOC series. Three read-only MCP servers over a live fabric, firewall pair, and cluster; three A2A specialists and a supervisor; a local-first planner; one guarded write path; an autonomous monitor. The one design law, and how to rebuild it.

Part 3 of the Agentic NOC series. The smallest real A2A agent: one skill, an Agent Card served at the well-known URL, and the actual message/send JSON-RPC captured live. The horizontal axis, one agent discovering and delegating to another, built from scratch, and how it composes with MCP.

Part 2 of the Agentic NOC series. The smallest real MCP server: one read-only tool, stdio transport, and the actual JSON-RPC handshake captured from a live run. Reproducible with one dependency. This is the vertical axis, an agent reaching a tool, built from scratch.

Anycast usually lets the network decide which datacenter answers. I moved that decision onto two GoBGP hosts that watch both datacenters and steer a single global VIP between them. Here's the design, the traffic flow, and three failover drills that came through with zero failed requests.

Part 1 of the Agentic NOC series. It introduces the two protocols that let AI agents reach tools and each other, MCP (the vertical axis) and A2A (the horizontal axis), and the third, ACP, that converged into A2A, plus the mental model the whole series is built on.
