Aether Developer

Wraps the Aether search API so Claude can query SEC filings, earnings call transcripts, and EU financial regulations (MiFID II, MiCA, CRR, GDPR) directly from chat. You get a handful of search tools that handle hybrid retrieval across those corpora. The underlying service is EvidInvest's financial agent search engine. Setup is the usual npx one-liner, then OAuth device flow on first run. The repo also ships TypeScript and Python HTTP clients if you want to call Aether outside an MCP context. Free tier gives you 5,000 calls per hour for three months, which is generous enough to prototype a research workflow or build a filing-analysis agent without hitting a wall.
