Give your AI agent SEC EDGAR data: a free remote MCP server for insider trades and XBRL financials

Description and use

The MCP server offers a simple interface to SEC EDGAR data, including insider trades, filings, and XBRL, freeing AI agents from manual HTTP handling, User‑Agent, and CIK lookup.

Problem

EDGAR data is free but hard to use for AI agents due to User‑Agent rules, CIK lookups, XML/XBRL complexity, and rate limits.

Outcome

The MCP server simplifies AI agent access to SEC EDGAR data, enabling quick retrieval of insider trades, market insider buys, filings, financial snapshots, XBRL concepts, and search results without handling low‑level HTTP details.

Workflow

• 1. Add MCP server URL to client config (Cursor, VS Code, Claude Desktop, Claude Code).
• 2. Initialize MCP via JSON‑RPC POST to https://sec‑edgar‑api.kidriahx.workers.dev/mcp.
• 3. Call desired tool (e.g., get_insider_trades) with arguments (ticker_or_cik, filings, max_rows).
• 4. Receive JSON result in result.content[0].text.
• 5. Use result in prompts or downstream processing.

Evidence

EDGAR is one of the best free financial datasets around: every insider trade, 10-K, 8-K and XBRL financial fact that U.S. public companies file.

Source

SEC's fair‑access policy asks every client to send a declared User‑Agent with a contact email and to stay under 10 requests per second.

Source

The server is stateless, so you don't need an SDK to test it. Every request is a single JSON‑RPC POST.

Source

Every tool takes a ticker or a CIK, and all of them are marked read‑only.
