Connect Claude Desktop to Aries so you can ask Claude to check your portfolio, get market data, or place orders — without writing code. You’ll add your Aries credentials in Claude once, sign in and approve access, and you’re done.

​
What you need

​
Step 1: Get your Client ID (common for all platforms)

Your Client ID comes from an OAuth client you create in Client Center. Set the OAuth redirect URI there when you generate the key (for authentication only). Then copy your Client ID — you’ll enter only the Client ID in Claude Desktop. Do this once: Create an OAuth client in Client Center

​
Step 2: Add the Aries MCP server in Claude Desktop

Tell Claude Desktop how to connect to Aries by adding the Aries MCP server and your Client ID. Client ID is required — the MCP connection will not work without it.
  1. Open Claude Desktop on your computer. (If you don’t have it yet, the link opens the download page.)
  2. Go to Settings (gear icon or File → Settings).
  3. Open MCP or Integrations (the name may vary by version).
  4. Click Add server or Add MCP server and add the Aries MCP configuration (use the server URL or config from Aries).
  5. When asked for Client ID, paste the value from Step 1.
  6. If you see Redirect URI, enter: https://mcp.aries.com/auth/callback.
  7. Save.
Where to find it: Settings → MCP (or Integrations) → Aries entry → enter your Client ID in the field shown.

​
Step 3: Complete the OAuth screen and grant permission

Start the connection from Claude Desktop. Your browser will open the Aries OAuth screen (sign-in and consent page) so you can approve access.
  1. In Claude Desktop, start the connection (e.g. Connect to Aries or Enable the Aries MCP server).
  2. Your browser opens the Aries OAuth screen.
  3. Sign in with your Aries email and password.
  4. Review the permissions and click Allow or Approve.
First-time permission grant: This permission screen appears only the first time you connect. If you miss it or close it without clicking Allow, it may not appear again. If that happens, remove the MCP server and add it again, or create a new OAuth client in Client Center, then complete the OAuth screen and grant permission.
  1. You’re redirected to the MCP callback; the gateway completes the token exchange. You’ll see a success message or return to Claude Desktop.
You only do this once. After that, Claude Desktop stays connected until you revoke access or the token expires.

​
Step 4: You’re connected

Claude Desktop is now linked to your Aries account. You can ask in plain language, for example:
  • “What’s in my Aries portfolio?”
  • “What’s the current price of AAPL?”
  • “Place a limit buy order for 10 shares of MSFT at $400.”
Claude uses the Aries API with the permissions you approved.

Troubleshooting

IssueWhat to do
“redirect_uri_mismatch”In Client Center, set the redirect URI to exactly https://mcp.aries.com/auth/callback (no trailing slash).
“invalid_client”Confirm your Client ID is correct and the client is active in Client Center.
“invalid_grant” or “code expired”The authorization code is one-time use. Start the connection again and complete login and approval without delay.
Claude Desktop doesn’t see AriesEnsure the MCP server is added and enabled, and that you completed Step 3 (OAuth login and approval). Restart Claude Desktop if needed.

  1. Open Claude Desktop on your computer. (If you don’t have it yet, the link opens the download page.)
  2. Go to Settings (gear icon or File → Settings).
  3. Open MCP or Integrations.
  4. Click Add server or Add MCP server and add the Aries MCP configuration.
  5. When asked for Client ID, paste the value from Step 1.
