io.github.EvidInvest/aether-developer is an MCP server with 14 tools an agent can call, among them financial_search, holdings_by_manager, holdings_by_security. It answers at https://aether.evidinvest.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 4 of 6 times since 11 September 2026; the last check, on 19 October 2026, succeeded.
Cited search over SEC filings, earnings transcripts and EU regulation, with fetch mode. 14 tools.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
financial_search | Search SEC filings (10-K, 10-Q, 8-K, registration statements/prospectuses and press exhibits; S&P 500 coverage, ~10 years) with hybrid semantic + keyword retrieval. TWO MODES. Search mode (pass `query`): results ranked by relevance, highest Inputs: query, issuer, fiscal_year, scope, domain, limit |
holdings_by_manager | What a fund owns: an institutional manager's reported equity book from SEC Form 13F — top positions by value, with quarter-over-quarter share changes and new/increased/decreased flags. Answers 'what does Bridgewater hold', 'what did this fu Inputs: manager, cik, issuer, period, limit |
holdings_by_security | Who owns a stock: institutional holders of a security from SEC Form 13F, ranked by position value, with quarter-over-quarter share changes. Answers 'who are the largest holders of NVDA', 'which funds added or trimmed this quarter', 'did any Inputs: ticker, cusip, issuer, period, limit |
list_partners | List active marketplace partners (sellers) and what each offers. Each partner has zero or more 'modes': `indexed` (free queries via partner_search against published documents) and/or `proxy` (queries routed server-to-server to the seller's Inputs: ticker, mode, limit |
partner_proxy_search | Route the agent's query server-to-server to one or more seller-registered API endpoints. Each call consumes prepaid Aether credits from the connected account at the per-call rate listed in list_partners (consumed regardless of result count) Inputs: query, partners, endpoints, issuer, ticker_filter, limit |
partner_search | Search marketplace partner documents (research notes, supply-chain analyses, etc. published by registered sellers). Returns ranked chunks with explicit per-document attribution and license terms. Pass `issuer` when the question is about one Inputs: query, partners, doc_types, issuer, scope, ticker_filter |
regulation_search | Search the text of EU financial regulation — a 29-act corpus (~13,000 citable chunks) covering markets & securities (MiFID II, MiFIR, MAR, Prospectus, EMIR, CSDR, Short-Selling, SFTR, Benchmarks), crypto & operational resilience (MiCA, DORA Inputs: query, celex, scope, doc_type, article, chunk_type |
search | Unified search across every Aether corpus at once — SEC filings, Japan/EDINET and Korea/DART annual reports, EU financial regulation, and earnings calls/press-release exhibits — auto-routed and merged into one corpus-tagged, citation-comple Inputs: query, issuer, fiscal_year, scope, tickers, limit |
seller_list_my_documents | List documents this seller has published. Returns status (pending / indexed / failed / revoked) and the indexed chunk count (`indexed_chunk_count`; the legacy alias `vespa_chunk_count` carries the same value for one release). Inputs: seller_api_key |
seller_list_my_endpoints | List proxy endpoints this seller has registered. Secrets are never returned — only a `secret_configured` boolean. Inputs: seller_api_key |
seller_publish_document | Publish (or update) a document into the marketplace. The content is chunked + embedded + indexed by a background worker; status moves from `pending` to `indexed` once that completes. Re-publishing the same external_doc_id replaces the prior Inputs: seller_api_key, external_doc_id, title, doc_type, license, ticker_coverage |
seller_register_endpoint | Register a proxy endpoint (Mode B). Aether stores your auth secret encrypted at rest (AES-256-GCM) and routes agent queries server-to-server — agents never see your URL or token. Charge per call via the `price_per_call_usd_cents` field. Acc Inputs: seller_api_key, slug, display_name, description, url, http_method |
seller_signup | Create a new marketplace seller account. Returns an API key (shown once). New accounts default to status='pending_review' — they can publish documents and register endpoints, but content is not surfaced in search until ops approves the acco Inputs: slug, org_name, contact_email, description, invite_code |
transcript_search | Search earnings-call transcripts and earnings press-release exhibits by speaker turn (CEO/CFO prepared remarks, analyst Q&A, press releases). Returns verbatim quotes as agent-ready payloads: speaker name/role, fiscal year + quarter, call da Inputs: query, issuer, fiscal_year, scope, ticker, lookback_quarters |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://aether.evidinvest.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
