Configure client

Clients that support OAuth connect with a SECSift sign-in, no API key required. Clients that do not can use an API key instead. Both reach the same account and the same credits.

The server

Point your client at:

https://mcp.secsift.com

The transport is Streamable HTTP, the current MCP standard. There's nothing to install and no local process to run.

Get an API key

Skip this if your client signs in with OAuth, like Claude does. For everything else, open the reader and sign in, then select your account at the bottom of the left sidebar and choose API keys from the menu. Create a key and copy it when it appears, because it is shown only once.

Note: You get up to 5 keys, and you can revoke any of them from the same screen.

Claude

On claude.ai:

  1. Open Settings, then Connectors.
  2. Choose Add custom connector and paste the server URL.
  3. Select Connect. Claude sends you to the SECSift sign-in, and approving it links your account. No key to copy.

Connectors you add there follow your Claude account, so SECSift is available in Claude on the web, the desktop apps, and mobile.

Custom connectors are on Claude's paid plans. Anthropic's connector guide covers the details.

Claude Code

Add it with an API key:

claude mcp add --transport http secsift https://mcp.secsift.com --header "Authorization: Bearer YOUR_KEY"

Or leave the header off, then run /mcp inside Claude Code to sign in with SECSift:

claude mcp add --transport http secsift https://mcp.secsift.com

The Claude Code MCP docs cover scopes, timeouts, and everything else.

Cursor and other clients

Add SECSift to the client's MCP config. In Cursor that is .cursor/mcp.json:

{
  "mcpServers": {
    "secsift": {
      "url": "https://mcp.secsift.com",
      "headers": { "Authorization": "Bearer YOUR_KEY" }
    }
  }
}

Clients that support OAuth can drop the headers line and sign in on first use. See Cursor's MCP docs for the details.

ChatGPT

In ChatGPT, connectors live under Settings, then Connectors, and adding a custom MCP server can require Developer mode. Choose Create and fill in the form:

Name:            SECSift
MCP server URL:  https://mcp.secsift.com
Authentication:  OAuth

ChatGPT sends you to the SECSift sign-in to finish. Availability varies by plan; OpenAI's connector guide has the current details.

Check it works

Ask your AI: "Using SECSift, find NVIDIA and list its recent filings." A working connection answers with the filings and links to SECSift. Reading is free, so this costs nothing; the first analysis request is what starts spending credits.

Troubleshooting

  • Unauthorized: The key was mistyped or revoked, or the header is not exactly Authorization: Bearer YOUR_KEY. Make a fresh key and reconnect. A revoked key can keep working for up to two minutes.
  • Out of credits: Analysis tools stop while reading tools keep working. Top up under Plans and credits.
  • Rate limited: The free tools allow bursts but not a flood from one key. Wait a few seconds and continue. There is also a daily reading allowance of 1,000 calls on the Free plan, 10,000 on Analyst, and 30,000 on Pro, which resets at midnight UTC.
  • Stuck on sign-in: Finish the SECSift sign-in in the window your client opens, then try the connection once more.

Note: Anyone who has your key can spend your credits. Treat it like a password, and revoke any key you are not using from the same API Keys screen.
