secapi-mcp

Official Model Context Protocol server for secapi.dev.

Expose SEC filings, financial statements, insider trades, and institutional holdings as AI-native tools for Claude, Cursor, ChatGPT, Windsurf, VS Code, and any MCP-compatible client.

AI Client  →  MCP Tools  →  secapi.dev REST API  →  JSON Response  →  LLM

This server never talks to databases directly — it is a typed, validated interface over the secapi-node SDK.

Features

  • 9 high-level AI tools designed for reasoning, not REST endpoint mirroring

  • SDK-first architecture — all API calls go through secapi-node

  • Zod validation on every tool input

  • AI-friendly errors with categories, suggestions, and retry hints

  • Structured JSON responses with metadata and pagination

  • Extensible tool registry — add new tools in minutes

  • Production logging — structured, secrets-safe

  • Full test suite with Vitest

  • CI/CD with GitHub Actions and Changesets

Adding a New Tool

  1. Create a tool definition in the appropriate src/tools/<domain>/index.ts:

{
  name: "my_new_tool",
  description: "Clear description for the LLM...",
  inputSchema: z.object({ ticker: tickerSchema }),
  handler: async (input, { client }) => {
    const data = await client.filings.search({ ticker: input.ticker });
    return createToolResponse("my_new_tool", data.data, {
      pagination: data.pagination,
    });
  },
}
  1. Export the module from src/tools/index.ts if it's a new domain.

That's it — the registry handles validation, error formatting, and MCP registration.

Troubleshooting

"API key is required" — Set SECAPI_API_KEY in your MCP client config env block.

"Invalid or missing API key" — Verify your key at secapi.dev. Keys are never logged.

"API rate limit exceeded" — Wait and retry, or upgrade your plan.

Server not appearing in Cursor — Restart Cursor after editing MCP config. Check stderr logs with SECAPI_DEBUG=true.

FAQ

Why not mirror REST endpoints 1:1? AI agents work better with semantic, high-level tools. company_overview is more useful than GET /entities/:id + GET /entities/:id/filings.

Can I self-host? Yes. Set SECAPI_BASE_URL if using a custom API deployment.

How do I add more tools? See Adding a New Tool. The framework is designed for fast extension.

    TDQS

    A3.7/5.0

    Scored across 9 tools

    Disambiguation5/5

    Each tool has a clearly distinct purpose: filing analysis, financials, company overview, ratios, insider trades, institutional holdings, and search functions for companies, filings, and institutions. No overlapping responsibilities.

    Naming Consistency4/5

    All tool names use snake_case, but there is a mix of verb-first (analyze_filing, search_*) and noun-first (company_*, institution_holdings) patterns. While readable, the inconsistency prevents a perfect score.

    Tool Count5/5

    With 9 tools, the server covers the essential SEC data retrieval operations without being bloated or too sparse. Each tool serves a well-defined need.

    Completeness4/5

    Core SEC filing and company data operations are covered (search, retrieve, analyze). Minor gaps exist, such as direct XBRL data extraction or historical filing comparisons, but the surface is largely complete for common workflows.
