shareseer/shareseer-mcp-server

A Model Context Protocol (MCP) server that provides access to ShareSeer's comprehensive SEC filings, insider transactions, and financial data through Claude and other MCP-compatible AI assistants.
🚀 Quick Start
Claude (web, desktop, or mobile)
No API key needed — you sign in with your ShareSeer account.
1. Go to **Settings → Connectors → Add custom connector**.
2. Enter the server URL https://shareseer.com/mcp and click **Continue**.
3. Claude detects **Sign in now** — leave it selected and click **Add**.
4. Click **Connect** and approve the request.
Claude receives a token scoped to your account that refreshes on its own. You can disconnect at
any time without affecting your API key.
If you don't have a ShareSeer account yet, sign up free at
shareseer.com/signup — you'll be prompted to sign in during step 4.
Claude Code and other MCP clients
Clients that prefer a static credential can pass your API key as a header instead. Get the key
from your profile page (it starts with sk-shareseer-).
Or in your project's .mcp.json:
The server accepts authorization, x-api-key, api-key, and x-auth-token, so whichever header
name your client offers will work. An Authorization value must include the Bearer prefix;
x-api-key takes the bare key.
