insider-signals-mcp

A thin local stdio MCP proxy for the TradeStar Insider server. It connects to the hosted MCP endpoint at https://mcp.tradestarinsider.com/mcp, reads the tool list from there, and exposes exactly those tools over stdio — so any MCP client that expects a local command (Claude Desktop, Cursor, VS Code, …) can use them.

• No API key. The free tier needs no credentials.
• Nothing hardcoded. The tool list and every result come straight from the remote server, which stays the single source of truth. Your client always sees the live tools.
• Filing-verified data. Every record carries its source filing_url on SEC.gov.

The tools cover SEC Form 4 insider-buy signals (today / by ticker / by date range / cluster buys), filing lookup, recent federal awards, activist 13D stakes, 13F fund position changes, and verification helpers.

Install & run

Pick one — both start the same proxy and require no install step of their own:

# Python (via uv)
uvx insider-signals-mcp

# Node
npx -y insider-signals-mcp

An optional environment variable INSIDER_SIGNALS_MCP_URL overrides the endpoint (for self-hosting or testing). If the remote is unreachable, the proxy returns a clear error that includes the status page (https://status.tradestarinsider.com) — it never hangs (30-second timeout) and never crashes silently.

Client configuration

Claude Desktop

claude_desktop_config.json → mcpServers:

{
  "mcpServers": {
    "insider-signals": {
      "command": "uvx",
      "args": ["insider-signals-mcp"]
    }
  }
}

Node variant:

{
  "mcpServers": {
    "insider-signals": {
      "command": "npx",
      "args": ["-y", "insider-signals-mcp"]
    }
  }
}

Cursor

~/.cursor/mcp.json (or Settings → MCP → Add):

{
  "mcpServers": {
    "insider-signals": {
      "command": "uvx",
      "args": ["insider-signals-mcp"]
    }
  }
}

Node variant: replace with "command": "npx", "args": ["-y", "insider-signals-mcp"].

VS Code

.vscode/mcp.json in your workspace (or MCP: Add Server):

{
  "servers": {
    "insider-signals": {
      "command": "uvx",
      "args": ["insider-signals-mcp"]
    }
  }
}

Node variant: replace with "command": "npx", "args": ["-y", "insider-signals-mcp"].

Prefer the hosted server directly?

Clients that support remote (streamable-HTTP) MCP servers can skip this proxy entirely and point at https://mcp.tradestarinsider.com/mcp. This package exists for clients that only accept a local command.
