Connect your AI app

You need a Definedge trading account and this address: https://mcp.definedgesecurities.com/mcp

Three steps in any app

1. Check whether Definedge is already there: Connectors in Claude, Plugins in ChatGPT.
2. If not, add it. Name: Definedge. Address: the one above. Authentication: No sign in (Claude suggests it) or No authentication (ChatGPT).
3. Sign in. In a chat, ask "Connect to my Definedge account." and sign in through the Definedge link.

Do step 3 again on a new device, or whenever the assistant says you are not signed in. The detailed steps for each app follow.

Claude

1. Open Claude at claude.ai or in the desktop app. Go to Customize → Connectors.
2. Click + Add, then Add custom connector. Name: Definedge. URL: https://mcp.definedgesecurities.com/mcp. Click Continue.
3. Click Continue again. Under Authentication, keep No sign in (Claude suggests it), then click Add. You sign in to Definedge from the chat instead.
4. In a new chat, click +, open Connectors and switch Definedge on.
5. Ask "Connect to my Definedge account." The assistant shows a Definedge sign-in link. Open it, sign in on signin.definedgesecurities.com, then come back and ask your question.

Optional: want Claude to ask you too before any order? Open Definedge in Customize → Connectors and, under Tool permissions, set the seven order tools (placeOrder, modifyOrder, cancelOrder, placeGttOrder, modifyGttOrder, cancelGttOrder, placeSliceOrder) to Needs approval. Definedge asks you to confirm every order either way.

Custom connectors work on every Claude plan; the Free plan allows one. You can also add the connector in the Claude mobile app: name, address, No sign in. Claude's help centre says connectors added on the web or desktop also appear in the mobile app. Servers added in Claude Code are separate and don't appear in the Claude apps.

Claude Team / Enterprise

1. An Owner adds the connector once: Organization settings → Connectors → Add → Custom → Web. Name: Definedge, URL: the address above. Click Continue, set Authentication to No sign in, then Add.
2. Each member finds Definedge (labelled Custom) in Customize → Connectors and switches it on in a chat. The assistant shows a Definedge sign-in link, and each member signs in with their own Definedge account.
3. Optionally, owners set Tool permissions for the organisation: the order tools to Needs approval, or to Blocked for members who only analyse.

Each person sees only their own Definedge account. Adding the connector for the organisation does not share anyone's account.

ChatGPT

Add the server on chatgpt.com. Once added, Definedge also works in the ChatGPT mobile app. This works on Plus, Pro, Business, Enterprise and Edu. On Business, only workspace admins and owners can add one. Free and Go are not confirmed: if your account has no Add custom MCP server option, use Claude.

1. Go to Plugins (chatgpt.com/plugins), click +, then Add custom MCP server.
2. Name: Definedge. Under Connection, enter https://mcp.definedgesecurities.com/mcp. Authentication: No authentication. You sign in to Definedge from the chat instead.
3. Tick I understand and want to continue, click Create as a plugin, then install the plugin.
4. In a new chat, type @, choose Definedge and ask "Connect to my Definedge account." Open the Definedge sign-in link the assistant shows, sign in on signin.definedgesecurities.com, then come back and ask your question.

ChatGPT asks you to approve a Definedge tool before it uses it. You can approve a tool for the rest of the conversation.

Claude Code

claude mcp add --transport http definedge https://mcp.definedgesecurities.com/mcp

Then ask a question and open the Definedge sign-in link the assistant shows. Claude Code keeps its own list: Definedge added here doesn't appear in claude.ai or the Claude apps. To block the order tools in a project, add them to permissions.deny in .claude/settings.json:

{ "permissions": { "deny": [
  "mcp__definedge__placeOrder",
  "mcp__definedge__modifyOrder",
  "mcp__definedge__cancelOrder",
  "mcp__definedge__placeGttOrder",
  "mcp__definedge__modifyGttOrder",
  "mcp__definedge__cancelGttOrder",
  "mcp__definedge__placeSliceOrder" ] } }

Cursor · VS Code

Cursor: ~/.cursor/mcp.json

{ "mcpServers": { "definedge": { "url": "https://mcp.definedgesecurities.com/mcp" } } }

VS Code: .vscode/mcp.json

{ "servers": { "definedge": { "type": "http", "url": "https://mcp.definedgesecurities.com/mcp" } } }

Use the agent or chat mode, and approve the sign-in when prompted.

Other clients

Clients that only support local (stdio) servers can use the mcp-remote bridge. This needs Node.js installed.

{
  "mcpServers": {
    "definedge": {
      "command": "npx",
      "args": ["mcp-remote", "https://mcp.definedgesecurities.com/mcp"]
    }
  }
}

Is "No sign in" safe?

Yes. "No sign in" (Claude) or "No authentication" (ChatGPT) only skips a sign-in step in the AI app's settings. Your Definedge account stays closed until you sign in through the Definedge link in the chat.

Menu names change

AI apps rename their menus from time to time. If a menu above looks different, search your app's help pages for "custom connector" or "MCP".
