The factory is becoming callable.
Machine Observer tracks where advanced-manufacturing capacity, engineering work and purchasing workflows are becoming machine-readable and programmatically accessible. The evidence ranges from digital manufacturing marketplaces to APIs that can quote and order parts and MCP surfaces that expose manufacturing entities directly to AI agents.
Digital manufacturing is already a material business.

This is a curated evidence catalog, not a census of manufacturing software. Capability presence is recorded independently; Machine Observer does not infer autonomous usage from an available interface.

No composite score yet
The machine economy reaches manufacturing when production capacity, engineering operations and commercial workflows become discoverable and callable by software.
- lower transaction cost for sourcing custom parts
- shorter design-to-quote loops
- programmatic access to production capacity
- agent-assisted engineering and planning
- more machine-readable production state and traceability
Boundary: A digital quote is not autonomous commerce. A REST API is not an AI agent. An MCP endpoint is not proof that agents are placing production orders. Each capability is recorded separately.
Still missing: public data on autonomous-agent manufacturing orders; machine-to-machine manufacturing payment volume; comparable longitudinal API call or order counts across providers; causal evidence connecting agent adoption to plant productivity.
