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.
- Go to Settings → Connectors → Add custom connector.
- Enter the server URL
https://shareseer.com/mcp and click Continue.
- Claude detects Sign in now — leave it selected and click Add.
- 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-).
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.

🐛 Troubleshooting
Common Issues
Claude doesn't show ShareSeer tools:
- Make sure you completed the Connect step — adding the connector alone doesn't sign you in
- Restart Claude after adding the connector
- Check that your ShareSeer account is active
Using a header instead of signing in, and calls fail:
- If you used
authorization, the value must start with Bearer (including the space);
x-api-key takes the bare key
- Verify your API key is correct and active on your profile page
"Rate limit exceeded" error:
- Check your current subscription tier limits
- Wait for the rate limit window to reset
- Consider upgrading to Premium for higher limits
- Spread out your queries over time
"Invalid API key" error:
- Verify your API key starts with
sk-shareseer-
- Check that your ShareSeer account is active
- Get a fresh API key from your profile page
