Transport: stdio, Streamable HTTP
Category: Search & AI memory
You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on the maker’s server: what you ask it goes through their server.
You fill in yourself: AETHER_API_KEY, Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Or run it on your computer

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "aether-developer": {
      "command": "npx",
      "args": [

      ],
      "env": {
        "AETHER_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add --transport http aether-developer https://aether.evidinvest.com/mcp --header 'Authorization: your-value'

Or run it on your computer

claude mcp add aether-developer --env AETHER_API_KEY=your-value -- npx -y @evidinvest/aether-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "aether-developer": {
      "url": "https://aether.evidinvest.com/mcp",
      "headers": {
        "Authorization": "your-value"

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

Common questions

Is Aether Developer safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.3.4) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa

Everything you need to connect Aether — the search engine built for agents, over SEC filings, earnings-call transcripts, and EU financial regulation — to your LLM, your IDE, or your own code.

Every result is a ready-to-cite evidence payload: the exact filed passage, an accession-numbered citation, the sec.gov / EUR-Lex link, and a confidence score. No filing, no answer — your agent stops inventing numbers.

MCP endpoint: https://api.aether.evidinvest.com/mcp · Auth: OAuth (sign in when your client prompts — free account).

Then ask: *"What does Apple's latest 10-K say about supply-chain risk? Quote the passage with the sec.gov link."* Name the company in the question — every tool takes an issuer, and naming it is what makes the answer scoped rather than a relevance-ranked sweep of every filer.

Teach your agent the craft (skills)

MCP gives the agent the tools; the skills/ directory teaches it the craft — tool routing, citation discipline, point-in-time transcript retrieval:

cp -r skills/aether-research ~/.claude/skills/   # Claude Code, personal

See skills/README.md for Claude Desktop / other frameworks.

Call the API from code

Four REST endpoints — the same tools MCP exposes (full reference):

POST /v1/tools/search   ← start here (unified)

POST /v1/tools/financial_search POST /v1/tools/transcript_search POST /v1/tools/regulation_search

Name the company, then narrow. Pass issuer on every call and the answer is scoped to that filer: fast and precise. Omit it and the call searches every issuer at once — slower, relevance-ranked only, and the response carries a quality_caveat. scope: "issuer" with no caveat is the only guarantee you got a filtered answer, so read both fields.

And query is optional: omit it, pass an identifier plus form_type / fiscal_year / section, and you get fetch mode — that filing's sections in filing order, no ranking, mode: "fetch", tens of milliseconds. If you already know which document you want, don't rank it.

TypeScript / Node

pnpm add @evidinvest/aether-sdk

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

const aether = new AetherClient({ apiKey: process.env.AETHER_API_KEY });

// search: the question in query, the company in issuer const out = await aether.financialSearch({ query: "supply-chain concentration risk", issuer: { ticker: "AAPL" }, fiscal_year: 2025, limit: 5, }); if (out.quality_caveat) console.warn(out.scope, out.quality_caveat); for (const c of out.results) { const start = c.metadata?.retrieval?.body_offset ?? 0; // skip the EDGAR cover page console.log(c.citation, c.metadata?.source_url, c.text.slice(start, start + 200)); }

// fetch: no query — Apple's latest 10-K risk factors, in filing order const risks = await aether.financialSearch({ issuer: { ticker: "AAPL" }, form_type: ["10-K"], section: "Item 1A", limit: 5, }); console.log(risks.mode); // "fetch" — and no confidence on any hit

Python

pip install evidinvest-aether-sdk

from aether import AetherClient

with AetherClient(api_key="ak_...") as aether: out = aether.financial_search( query="supply-chain concentration risk", issuer={"ticker": "AAPL"}, fiscal_year=2025, limit=5, ) if out.quality_caveat: print(out.scope, out.quality_caveat) for c in out.results: start = c.body_offset or 0 # skip the EDGAR cover page print(c.citation, c.metadata.get("source_url"), c.text[start : start + 200])

fetch: no query — Apple's latest 10-K risk factors, in filing order

risks = aether.financial_search( issuer={"ticker": "AAPL"}, form_type=["10-K"], section="Item 1A", limit=5 ) print(risks.mode) # "fetch" — and confidence is None on every hit

Get an API key

https://aether.evidinvest.com/developer/keys — anonymous calls work but are rate-limited; keys are free.

What's in the corpus

SEC filings — 10-K / 10-Q / 8-K, registration statements, prospectuses, press exhibits; ~10 years of S&P 500 and beyond.
Non-US registries — Sweden (Bolagsverket), Japan (EDINET), Korea (DART) annual reports. Reach a non-US filer by name — issuer: {company_name: "Sivers Semiconductors"} — or scope a whole market with jurisdiction: ["SE"|"JP"|"KR"].
Earnings calls — speaker-attributed transcripts + furnished press exhibits, with point-in-time filters (order: "earliest" finds first mentions) and the issuer's own fiscal_year + quarter.
EU regulation — MiFID II, MiCA, DORA, the AML package; article-level citations.

3 months free. Verify your email when you sign up and you're on the trial tier automatically — up to 5,000 API calls/hour on Aether's search tools, free for 3 months. No card required; it reverts to the free tier (100 calls/hour + paid credits) when the trial ends.

Contribute a client library

The TypeScript and Python clients are intentionally tiny — one bearer-token fetch wrapper + typed shapes for the /v1/tools/* endpoints. Porting to Go, Rust, Java, etc. is ~150 lines. Open a PR under clients/ /. Whatever you write, surface scope, quality_caveat, mode and each hit's body_offset: a client that drops them leaves its users unable to tell a precise answer from an approximate one. Response fixtures to test against live in clients/fixtures/.
