Options Data MCP Server

1. 01

   Add the server

   Run this on its own. It registers the server. It does not finish sign-in.

   claude mcp add --transport http moontower https://api.moontower.ai/mcp

2. 02

   Sign in with OAuth

   In Claude Code, open /mcp, select moontower, and choose Authenticate. Approve the connection in the browser.

   /mcp → moontower → Authenticate → Allow

3. 03

   Or pass an API key

   For scripts or headless clients, send the same key as the REST API in the X-API-Key header. The value starts with mtw_. The export uses the placeholder mtw_.... A real key typed into that export is stored in shell history.

   export MOONTOWER_API_KEY="mtw_..."
   claude mcp add --transport http moontower https://api.moontower.ai/mcp \
     --header "X-API-Key: $MOONTOWER_API_KEY"

4. 04

   Or write .mcp.json

   Same API-key path, in a project file. Claude Code expands ${MOONTOWER_API_KEY}. A raw $MOONTOWER_API_KEY, or an unexpanded ${MOONTOWER_API_KEY}, will not authenticate.

   {
     "mcpServers": {
       "moontower": {
         "type": "http",
         "url": "https://api.moontower.ai/mcp",
         "headers": {
           "X-API-Key": "${MOONTOWER_API_KEY}"
         }
       }
     }
   }

5. 05

   Verify the connection

   After you allow the connection, claude mcp get moontower should show https://api.moontower.ai/mcp. On the API-key path it should also show an X-API-Key header.

   claude mcp get moontower
