Access SEC filings, insider transactions, and financial data via the ShareSEER API.
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.
No API key needed — you sign in with your ShareSeer account.
https://shareseer.com/mcp and click Continue.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.
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-).
claude mcp add --transport http shareseer https://shareseer.com/mcp \
--header "Authorization: Bearer sk-shareseer-YOUR_API_KEY_HERE"
Or in your project's .mcp.json:
{
"mcpServers": {
"shareseer": {
"type": "http",
"url": "https://shareseer.com/mcp",
"headers": {
"Authorization": "Bearer sk-shareseer-YOUR_API_KEY_HERE"
}
}
}
}
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.
