toolstem/toolstem-sec-mcp-server

**SEC EDGAR intelligence for AI agents.** Five composite tools that pre-compute high-value signals directly from SEC EDGAR's public submissions API, returned as structured JSON.
> **No SEC API key required.** Data is sourced directly from SEC EDGAR's public submissions API. A built-in sliding-window rate limiter keeps traffic under SEC's 10 rps fair-access ceiling automatically.

Quickstart — hosted endpoint (recommended)
Point your MCP client or agent at the hosted endpoint. **No API key, no infra, no setup.** Billing is per-call via x402 — the agent's wallet pays directly in USDC on Base mainnet.
- **No SEC API key, no signup, no marketplace account** — the agent's wallet pays directly.
- **No infrastructure** — nothing to install, host, or keep running.
- **No setup** — connect an MCP client and call a tool.
- initialize and tools/list are **free** (discovery and schema introspection).
- tools/call is **tiered per tool** (see Pricing below).
Claude Desktop
Drop this into your claude_desktop_config.json:
Restart Claude Desktop, then ask: *"Has TSLA disclosed any material 8-K events in the last 90 days?"*
Any MCP client (LangChain.js)
The official @langchain/mcp-adapters library connects directly to the hosted URL:
LangChain quick-start (langchain-toolstem)
The langchain-toolstem wrapper handles x402 payment for you — pass a funded wallet key and the SEC tools are included automatically:
Prefer to run the server yourself over stdio/HTTP? See Advanced: self-host at the bottom.

The five tools
All five tools are composite/curated (they compute derived signals or aggregate across multiple EDGAR endpoints — no raw passthroughs). Annotations: readOnlyHint: true, destructiveHint: false, idempotentHint: true, openWorldHint: true.
