The MCP server for US public financial disclosures.

One queryable surface for every public US financial disclosure that matters.

KeyVex normalizes 41+ distinct US public-record sources into a clean Model Context Protocol (MCP) server with 38 agent-native tools. Connect it to Claude, Cursor, your custom agent, or any MCP-compatible client. No scraping, no parsing, no schema-wrangling on your end.

One tool call. Every source that matters.

Live demo · unified_search(ticker:"LMT") fanning out across the disclosure surface in one round trip.

Most financial-data APIs give you one narrow view. KeyVex's tools are designed to chain — and the unified_search tool shown above does the chaining for you. When you want to drive the chain manually, the same composition is just as natural:

Agent: get_congressional_trades(ticker:"LMT", since:"2026-01-01")
→ 23 trades by senators and reps in Lockheed Martin stock

Agent: get_member_profile(bioguide_id:"<each trader's id>")
→ party, state, committees — including who sits on Armed Services

Agent: get_roll_call_votes(legislation_type:"HR", since:"2026-01-01")
→ defense-related bills those members actually voted on

Agent: get_federal_contracts(recipient_name:"Lockheed Martin", since:"2026-01-01")
→ 1,247 LMT contracts awarded by DoD

Agent: get_fundamentals(ticker:"LMT", category:"income_statement")
→ LMT's actual revenue + operating income trend, quarter by quarter (XBRL)

Agent: get_lobbying_filings(client_name:"Lockheed Martin", filing_year:2026)
→ LMT's lobbying spend, what issues, what agencies contacted

Agent: get_proxy_filings(ticker:"LMT")
→ exec comp + board nominations + shareholder proposals

Agent: get_insider_transactions(ticker:"LMT")
→ insider buys/sells from the company's officers + directors

Agent: get_enforcement_actions(text:"Lockheed")
→ any SEC / DOJ / CFTC / OCC / FDIC actions involving LMT

Agent: get_economic_indicators(category:"rates", latest_only:true)
→ Fed Funds + 10Y Treasury + mortgage rate context (FRED)

Agent: get_treasury_auctions(security_type:"Note", since:"2026-01-01")
→ bond-market sentiment / demand backdrop

Agent: get_fec_candidate_profile(candidate_name:"<member name>")
→ that member's FEC candidate ID + principal campaign committee

Twelve separate disclosure sources, joined by ticker + bioguide_id + recipient_name + company name. Triangulation that takes a Bloomberg terminal and an analyst — fundamentals from a separate provider — and a macro data subscription on top, all combined into a single AI agent conversation in a few seconds.

Or in one tool call:

Agent: unified_search(ticker:"LMT", per_source_limit:5)
→ fans out to 9 collections in parallel
→ returns one envelope grouped by source —
   insider_trades, congressional_trades, planned_insider_sales,
   activist_ownership, material_events, proxy_filings, ...
→ sub-second response across the full disclosure surface

From Claude Desktop: add KeyVex to your claude_desktop_config.json as a remote MCP server — no token required for preview access. One-click install through Anthropic's MCP directory once review completes.

Pay for what you actually use.

Generous free tier. Hard quotas, no overage charges. Same data freshness at every tier — the only difference is monthly call quota and support response time.

When you hit your monthly limit, requests are politely rejected until the next month or you upgrade. No surprise bills.

Built for the people building tools.

KeyVex isn't a dashboard. It isn't a stock-picker. It's data infrastructure for the people building the next generation of financial-research tools and AI agents.

Built for production agents, not prototypes.

The plumbing behind the response is what separates infrastructure from an experiment. KeyVex runs autonomously, returns audit-grade provenance on every record, and is indexed for the cross-source queries agents actually compose — not just the easy single-collection ones.

Pure-publisher posture. Public-record data only.

KeyVex takes the raw, fragmented data that US government repositories publish — SEC EDGAR XML, House Clerk PDFs, Senate eFD HTML behind a CSRF gate, USAspending JSON, FEC's paginated APIs, and a dozen more — and presents it clean, normalized, and ready to use. Parsed, ticker-resolved, schema-unified, idempotent — shaped for your agent to query directly. What we don't add on top is derived signals: no trading recommendations, no investment advice, no scoring or ranking of securities, no claims about future performance.

Source-faithful, byte-exact, auditable. We don't silently alter what SEC published either. Sentinels, filer typos, the full set of source-side quirks — preserved byte-for-byte. Conventions are explained in each tool's description; a source_metadata block annotates the quirks at read time so your agent reads them correctly. Audit any KeyVex record against EDGAR — the bytes match.

This isn't a marketing distinction — it's a deliberate legal posture (Lowe v. SEC, 1985) that keeps KeyVex cleanly outside investment-advisor territory. We do the data work; what you build on top of it is yours.
