Query HRIS and ATS data inside Claude Desktop

Stop wasting time context-switching between tools. When you run this MCP Server locally, your agent uses `list_employees` and `list_candidates` to pull real-time team and recruiting data straight into your chat interface. You don't have to copy-paste JSON payloads from your terminal anymore. The desktop app executes these tools via stdio transport as a subprocess on your machine. This means Claude Desktop can instantly read from your unified integrations and help you cross-reference active job candidates with your current employee headcount.

Fetch CRM contacts and tickets on demand

Keep tabs on customer interactions without opening a browser. Your agent can call `list_contacts` and `list_tickets` to pull live CRM accounts and support issues directly into your conversation. If you prefer the browser, you can configure Claude Desktop using the custom connector path on claude.ai. Just paste your remote MCP server URL, authenticate once, and let your agent handle the API calls behind the scenes.

Inspect integration boundaries and accounts

Debugging sync issues is a pain when you don't know where the data breaks. This server lets you run `get_account_details` and `list_accounts` to check exactly which third-party systems are actively linked. Your agent uses this metadata to map where customer records live and pinpoint failing syncs. You get clean, structured outputs inside your workspace without writing custom testing scripts.
