MCP server for solar economics: retail tariffs (OpenEI URDB), electricity prices (EIA), incentives (DSIRE), and auditable ROI estimates
Listed on its own since 2026-09-27. Until then it was part of solar-data, where its earlier checks remain.
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"solar-data-mcp-economics","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

# solar-data-mcp-economics MCP server answering "would solar pay off here?" with cited, decomposable numbers — the economics domain of [solar-data-mcp](https://github.com/hoodsy/solar-data-mcp). | Tool | Answers | |---|---| | `lookup_tariffs` | "Which rate schedules serve this address?" (OpenEI URDB) | | `get_electricity_prices` | "What do people pay in Colorado, and which way is it trending?" (EIA v2) | | `get_incentives` | "What can I claim this year?" (federal ITC + DSIRE snapshot) | | `estimate_roi` | "Payback, NPV, IRR?" — the flagship composite, with a full audit trail | | `sync_incentives` | Load a DSIRE program export into the local store | Run standalone: `uvx --from solar-data-mcp-economics solar-economics-mcp`. Keys: `OPENEI_API_KEY` (tariffs), `EIA_API_KEY` (prices), `NREL_API_KEY` (the production model inside `estimate_roi`) — all free; a tool missing its key returns setup instructions. Most users want the combined [`solar-data-mcp`](https://github.com/hoodsy/solar-data-mcp/blob/main/packages/solar-data-mcp/README.md) server instead — all four domains plus the skill and report layer on one install. Quickstart: [repo README](https://github.com/hoodsy/solar-data-mcp#quickstart).
