Toolstem Sec MCP server

SEC EDGAR MCP Server — Insider Signals, 13D Activist Risk & Filing Intelligence

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.

https://mcp.toolstem.com/mcp/sec

• 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 claudedesktopconfig.json:

{
  "mcpServers": {
    "toolstem-sec": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.toolstem.com/mcp/sec"
      ]
    }
  }
}

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:

import { MultiServerMCPClient } from "@langchain/mcp-adapters";
import { ChatOpenAI } from "@langchain/openai";
import { createReactAgent } from "@langchain/langgraph/prebuilt";

const client = new MultiServerMCPClient({
  toolstem_sec: {
    transport: "http",
    url: "https://mcp.toolstem.com/mcp/sec",
    // Add your x402-signing middleware via headers, OR run an x402
    // proxy locally and point url at it. See https://www.x402.org/clients.
  },
});

const tools = await client.getTools();
const agent = createReactAgent({ llm: new ChatOpenAI({ model: "gpt-4o-mini" }), tools });
await agent.invoke({ messages: "Has TSLA disclosed any material 8-K events in the last 90 days?" });

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:

import { createToolstemTools } from 'langchain-toolstem';
const tools = await createToolstemTools({ walletPrivateKey: process.env.WALLET_KEY });
// SEC tools included automatically — agents pay per call in USDC

Prefer to run the server yourself over stdio/HTTP? See Advanced: self-host at the bottom.

Try the tools live in the Toolstem playground.

Pricing

• MCP initialize and tools/list are free — discover the server and its tool surface without paying anything.
• tools/call is tiered per tool, paid in USDC on Base mainnet via x402. No API key, no signup, no marketplace account — agents pay directly from their own wallet.
