ai agents

A DCI link goes down at 18:00. Nexus Dashboard's syslog export lands seven seconds later, the triage turns it into one incident, the investigation names the link, and the fix goes through NDFC with an approval bound to the exact lines a human read. Part 2 of FabricSRE.

Nexus Dashboard 4.3.1 exposes enough over its GA API to build a real SRE agent. Part 1: the rules, the fabric twin, a ten-hypothesis investigation with evidence on every line, and the fault harness that proves it names the right failure.

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 4 of the Agentic NOC series. A cited timeline: MCP won the vertical axis in a year, A2A won the horizontal axis with a hundred-company tent, and ACP converged into A2A under the Linux Foundation rather than fragmenting the field. Why building on MCP plus A2A today is the safe bet.

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.

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.
