What GPCP reads
GPCP reads each source through a Model Context Protocol server. The page is what those servers returned, plus the encoded rule set. Lease polygons are from the public Bureau of Land Management Mineral and Land Records System. Connector status is read from the published SEPI index at sepi.thermalunderground.org/connectors.json.
Each server wraps one source and exposes read-only tools. Each response carries its source name, endpoint, and retrieval timestamp.
| Server | Source |
|---|---|
ecfr | eCFR and Federal Register public APIs |
ipac | USFWS IPaC Location API |
sepi | SEPI · BLM AFMSS well records |
gpcp-timeline | Encoded dependency rule set |
The schedule is computed from the rule set by topological sort. Same input, same output, every time.
MCP servers are local processes. A static host cannot run them. This site publishes what they produced, with geospatial and reference records from public federal services.
Provenance
Every record carries a marker.
SEPI
Connector status supplied through the Subsurface Energy Permitting Index. SEPI is a separate system. GPCP reads the published index. Records that arrive through SEPI are marked SEPI on that project’s identifier layer.
Captured
