A user says Fable 5 in Cowork built an end-to-end MCP server in one shot.
- They expected a plan they could review, but after approving the plan the system kept working for about 2 hours.
- The logs reportedly showed it spinning up around 70 agents.
- The result was a complete MCP server that actually worked, after the user had spent about a week trying to build a different one manually and was still not halfway done.
- The post frames this as a dramatic productivity boost for agentic coding workflows.
