Your First Tool Call

Once you’ve connected a service and configured your MCP client, it’s time to verify everything works.

Testing with Claude Desktop

The easiest way to test is by asking Claude to use one of your connected tools.

Test Gmail

If you’ve connected Google, try asking:

“Check my unread emails from today”

Claude will use the gmail_search tool to query your inbox and return the results.

Test Slack

If you’ve connected Slack, try:

“What are the recent messages in #general?”

Claude will use slack_get_channel_history to fetch messages.

Test Calendar

“What meetings do I have tomorrow?”

Claude will use calendar_list to show your upcoming events.

Understanding Tool Responses

When a tool executes successfully, you’ll see:

The tool name Claude is calling (e.g., gmail_search)
The parameters being passed
The response with your data

Debugging Issues

”Service not connected”

This means Fp Switchboard doesn’t have a valid token for the service. Go to the dashboard and reconnect the service.

”Rate limited”

The external service (Google, Slack, etc.) has temporarily blocked requests. Wait a few minutes and try again.

”Invalid token”

Your Fp Switchboard token may have been revoked. Generate a new token from the dashboard.

No response

Check that your MCP client is properly configured
Verify the token is correctly copied (no extra spaces)
Try restarting your MCP client

  -H "Authorization: Bearer fps_unified_your_token" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",

    "method": "tools/list"
  }'

This returns a list of all available tools for your connected services.
