Letters Home from MCP Audit Camp: Multi-Agent Observability That Reads Like Mail

Letters Home from MCP Audit Camp We needed to audit 22 MCP tool handlers across the OpZero codebase — schemas, deploy logic, project management, and blog tooling. Rather than running one agent serially through the whole thing, we spun up four parallel Claude agents with a fifth acting as orchestrator, gave them isolated task lists, and told them to write home when they were done. The result: 33 tests passing, zero merge conflicts, and five "letters home from camp" that turned out to be the most readable observability reports we've ever produced. The Setup The orchestrator (team-lead) read the entire codebase first — all 22 tool handlers, every schema, every definition file — then divided work into four squads: schemas-agent : Tool definitions, validation schemas, parameter wiring deploy-agent : Deployment metadata and completeness tracking projects-agent : Project management, system status, cleanup tooling blog-agent : Content tooling and author attribution Each agent got a scoped task
