Overview

AI-generated overview

ShareSEER is a remote MCP server that lets an assistant look up SEC filings, insider transactions and company data through the ShareSEER API.

What you can do
Look up company details by ticker symbol and list a company's recent SEC filings and insider transactions. Scan market-wide recent SEC filings and recent insider trading activity. Find the largest daily or weekly insider transactions by buyers or sellers. Results depend on the account tier, with free accounts limited in history, freshness, result counts and pagination.
When to use it
Useful when you want an assistant to answer questions about US public companies, their SEC filings, or insider buying and selling, such as recent 10-K filings or the biggest insider purchases this week.
Requirements
A remote endpoint at shareseer.com/mcp over streamable HTTP. A ShareSEER account is required; sign in through OAuth, or pass an API key from your profile page in an authorization, x-api-key, api-key or x-auth-token header. Network access is needed.
Before you install
The API key (starts with sk-shareseer-) is a credential; keep it out of shared files and revoke it if exposed. Free tier is rate-limited and delayed, and Premium costs $49/month. Queries and account data go to ShareSEER as a third party.

Installation

In SourceWeft

  1. Open ShareSEER in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.shareseer%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

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-).

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:

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
