Crypto discovery/caps (CoinMarketCap), Fed macro series with point-in-time vintages (FRED/ALFRED), and the FOMC decision calendar as an MCP server and scion-sdk source adapters
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":"bellwether-mcp-2","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

# bellwether-mcp *Version: 1.3.8* > **Documentation** — Installation, deployment, and tool usage are maintained in the > [official documentation](https://knuckles-team.github.io/bellwether-mcp/). Crypto discovery/rankings/market caps (CoinMarketCap), Fed macro and liquidity series with point-in-time vintages (FRED/ALFRED), and the FOMC decision calendar (hike/cut/hold, sourced) — as an MCP tool surface and, through `scion-sdk`'s declarative `mcp_tool` source adapter, as bounded, checkpointed ingestion streams intended for EG's `finance-v1` world-model ontology (`feat/finance-core`, not yet published — see AGENTS.md). **Not a venue-specific OHLCV feed.** CoinMarketCap's general historical OHLCV endpoint documents hourly/daily coverage only, not minute-level exchange candles — pair this package with an `emerald-exchange` backend for tradable bars and charts. ## Sources | Ledger row | Sources | Target class (provisional) | |---|---|---| | EH-412 (crypto discovery/caps) | CoinMarketCap listings/quotes/global-metrics | `Instrument`, `MacroEvent` | | EH-412 (Fed macro series) | FRED/ALFRED `series/observations`, `series/vintagedates` | `EconomicIndicator` | | EH-412 (FOMC calendar) | Curated dataset, sourced to federalreserve.gov press releases | `MacroEvent` | | EH-422 (macro/liquidity) | FRED named aliases: `WALCL`, `WDTGAL`, `M2SL`, `RRPONTSYD`, `WRESBAL`, `DGS10`, `DTWEXBGS` | `EconomicIndicator` | `Instrument`, `EconomicIndicator` and `MacroEvent` are the design doc's own proposed finance-v1 class names (`plans/refactor/proposals/FINANCE-INTEGRATION-20260924.md` section 4/7). EG's `feat/finance-core` branch, which owns finance-v1, has not published anything yet as of this package's build — see AGENTS.md "Ontology mapping" before trusting these as final. ## Tools Nine MCP tools, one FastMCP server (`bellwether-mcp` console script): `cmc_listings`, `cmc_quotes`, `cmc_global_metrics`, `fred_macro_series_aliases`, `fred_series_observations`, `fred_series_observ…
