Which integrations does Merge support through the unified API?

Merge supports over 150+ integrations across HRIS (BambooHR, Workday), ATS (Lever, Greenhouse), CRM (Salesforce, HubSpot), and Ticketing (Zendesk, Jira). Your agent can access all of them using the same standardized tools once the accounts are linked in Merge.

How do I target a specific customer's data through the agent?

Each request requires a `MERGE_ACCOUNT_TOKEN` which uniquely identifies a linked account (e.g., a specific customer's integration). By providing this token along with your API key, your agent can retrieve data exclusively from that customer's connected platform.

Can my agent list candidates from my ATS and support tickets from Zendesk at the same time?

Yes. Since Merge unifies multiple categories, your agent can use the `list_candidates` and `list_tickets` tools in the same conversation to bridge data from different functional areas of your business instantly.

Merge (Unified Integration API) + Claude Desktop FAQ

Common questions about integrating Merge (Unified Integration API) MCP Server with Claude Desktop.

How does Claude Desktop discover MCP tools?

When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.

What happens if the MCP server is temporarily unavailable?

Claude Desktop handles disconnections gracefully — if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.

Can I connect multiple MCP servers simultaneously?

Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.

Is there a limit on the number of tools per server?

Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.

Does Claude Desktop support Streamable HTTP transport?

Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL — Claude auto-negotiates the transport protocol.
