Documentation

From the project's GitHub README.

aether-developer

Everything you need to call Aether — the financial-vertical agent search engine — from your own code or your favourite MCP-enabled IDE.

The repo holds two kinds of integration plus the docs that explain them:

MCP wrapper — @evidinvest/aether-mcp. Drop it into Claude Desktop, Cursor, Cline, or any stdio-MCP client and you can search SEC filings + earnings transcripts from chat.
Client libraries — small typed HTTP clients in TypeScript / Python (and more languages over time). For when you're building your own service instead of using an MCP-aware UI.

Quick start

Claude Desktop / Cursor / Cline (MCP)

Add this to your client's MCP-server config:

{
  "mcpServers": {
    "aether": {
      "command": "npx",
      "args": ["-y", "@evidinvest/aether-mcp"]
    }
  }
}

First run prints a device-code URL — open it, sign in, approve. Full guide: docs/mcp.md.

TypeScript / Node

pnpm add @evidinvest/aether-sdk

import { AetherClient } from "@evidinvest/aether-sdk";

const aether = new AetherClient({ apiKey: process.env.AETHER_API_KEY });
const { hits } = await aether.search({ query: "Apple supply-chain risk", limit: 5 });

Full guide: clients/typescript/README.md.

Python

pip install aether-sdk

from aether import AetherClient

with AetherClient(api_key="ak_...") as aether:
    result = aether.search(query="Apple supply-chain risk", limit=5)
    for hit in result.hits:
        print(hit.score, hit.section_title)

Full guide: clients/python/README.md.

Docs

docs/search.md — request/response shapes, auth, schemas.
docs/mcp.md — MCP setup for Claude Desktop, Cursor, Cline, env overrides.

Contribute a client library

The TypeScript and Python clients are intentionally tiny — one bearer-token fetch wrapper + typed shapes for /v1/search. Porting to Go, Rust, Java, etc. should fit in ~150 lines. Open a PR under clients/<lang>/.
