Connect Claude Mobile (Claude on your phone) to Aries so you can ask Claude for portfolio info, market data, or to place orders — by voice or text. You’ll add your Aries credentials in the app 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 Mobile. Do this once: Create an OAuth client in Client Center

​
Step 2: Add the Aries MCP server and your credentials in Claude Mobile

Tell Claude Mobile 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 the Claude app on your phone. (Don’t have it? iOS · Android)
  2. Go to Settings (profile or gear icon).
  3. Open Integrations, MCP, or Connected apps (the name may vary by version).
  4. Tap Add integration 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 → Integrations or Connected apps → Aries entry → enter your Client ID in the field shown.

​
Step 3: Complete the OAuth screen and grant permission

Start the connection from Claude Mobile. A browser (in-app or on your device) will open the Aries OAuth screen (sign-in and consent page) so you can approve access.
  1. In Claude Mobile, start the connection (e.g. Connect to Aries or Enable the Aries MCP server).
  2. A browser opens the Aries OAuth screen.
  3. Sign in with your Aries email and password.
  4. Review the permissions and tap 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 tapping 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 Mobile.
You only do this once. After that, Claude Mobile stays connected until you revoke access or the token expires.

​
Step 4: You’re connected

Claude Mobile is now linked to your Aries account. You can use voice or text to ask, 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 the OAuth screen and approval without delay.
Claude Mobile doesn’t see AriesEnsure the MCP server is added and enabled, and that you completed Step 3 (OAuth login and approval). Restart the Claude app if needed.
Browser doesn’t return to ClaudeAfter approving, if you’re not sent back to the app, open Claude Mobile again and check Settings → Integrations to see if Aries is connected.

How it works

The flowchart below shows the full connection flow. The sections under it are expandable — closed by default; click a step heading to open and see the details.
Where: Client Center → API
  1. Open Client Center and go to the API section.
  2. Click Generate Key.
  3. Fill in client name (e.g. “Claude MCP”), Redirect URI https://mcp.aries.com/auth/callback, and scopes. The redirect URI is for authentication only.
  4. Save and copy your Client ID (you only enter this in Claude).
Where: Claude app → Settings → Integrations or MCP
  1. Open the Claude app on your phone. (Don’t have it? iOS · Android)
  2. Go to Settings (profile or gear icon).
  3. Open Integrations, MCP, or Connected apps.
  4. Tap Add integration or Add MCP server and add the Aries MCP configuration.
  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: Claude Mobile, then your browser (Aries OAuth screen)
  1. In Claude Mobile, start the connection (Connect to Aries or Enable the Aries MCP server).
  2. A browser opens the Aries OAuth screen. The first-time permission grant appears only once — don’t miss it.
  3. Sign in with your Aries email and password and tap Allow or Approve.
  4. You’re redirected to the MCP callback; the gateway completes the token exchange. You’ll see a success message or return to Claude Mobile.
