**Bug: Claude.ai Pipedrive MCP connector passes incorrect field names for email and phone on Person records**

API
1

Summary:
The Pipedrive MCP connector used in Claude.ai is passing email and phone (singular) when creating or updating Person records. The Pipedrive v2 API requires emails and phones (plural), and rejects the requests with the following validation error:

Validation failed: email: Parameter ‘email’ is not allowed for this request; phone: Parameter ‘phone’ is not allowed for this request

Steps to reproduce:

  1. Use the Claude.ai Pipedrive MCP connector
  2. Call pipedrive_create_person or pipedrive_update_person with email and phone fields
  3. The API call fails with the validation error above

Expected behavior:
Email and phone should be passed as emails and phones (plural arrays) per the Pipedrive v2 API spec:

{
  "emails": [{"value": "example@email.com", "primary": true, "label": "work"}],
  "phones": [{"value": "555-555-5555", "primary": true, "label": "work"}]
}

Actual behavior:
The connector sends email and phone (singular), which the v2 API rejects.

Fix:
Update the MCP connector tool definition to use emails and phones as the parameter names to match the Pipedrive v2 API specification.
