Works with Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This connection provides 8 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.
Gathering a unified view of customer and employee data shouldn't require logging into five different tools.
Today, building a single report means opening the CRM to check contacts, switching tabs to the HRIS for employee status, then jumping over to the ticketing system just to see if that contact has an open issue. You spend more time clicking and copy-pasting than analyzing.
With Merge's MCP Server, you simply ask your agent: "Give me all active employees who have open support tickets." The server executes `list_employees` and then runs `list_tickets`, correlating the data instantly and giving you one clean response.
Using Merge (Unified Integration API) MCP Server: Streamline your B2B Data Access
The most time-consuming manual steps disappear. You no longer have to write multi-stage scripts or manage multiple authentication tokens for different services just to pull a basic list of contacts and candidates.
You get one unified API endpoint that abstracts away the complexity of connecting Workday, Salesforce, Zendesk, and others. It's reliable data access, period.
What your AI can actually do with this
You connect your AI agent to Merge and it hooks you up with data from HRIS, ATS, CRM, and ticketing platforms. You use one chat window for everything—you list employees from Workday, check candidates in Greenhouse, or pull support tickets from Zendesk. It unifies all that messy business junk—from employee profiles to customer issues—so your agent can query it right away.
Getting started? Your AI client just needs to talk to the server. You don't gotta jump between dashboards or write complex API calls just to gather a report. The system handles routing and data standardization across all those systems.
Account Setup & Boundaries:get_account_details retrieves metadata about the linked account, letting you review integration boundaries; list_accounts gets a list of customer accounts mapped inside your CRM integration.
HRIS Data (Employees & Companies):
You can check out all active employees using list_employees; it handles large data sets. You also get organizational company details by calling list_companies, pulling structured lists from your connected HR system.
ATS Data (Candidates & Applications):
Want to see who's in the pipeline? list_candidates pulls a list of all recruited candidates across the entire ATS integration. To check job applications, you run list_applications, getting every application currently stored within your ATS setup.
CRM Data (Contacts & Accounts):
You access external sales contacts using list_contacts, grabbing every contact defined in your CRM integration. You can also call list_accounts to get a list of customer accounts mapped inside the system.
Ticketing Board:
The server lets you pull support tickets, running list_tickets retrieves all inbound and outbound support issues from your issue-tracking board.
Your agent uses these tools together. You can ask it to find employees who are also listed as external contacts, or check the status of a candidate while pulling up related customer accounts—all in one go.

Here's how it actually works
The bottom line is: You ask a question about your business data once, and the server handles connecting to all the right places to answer it.
Subscribe to the server and input your Merge API Key and dedicated Account Token.
Send a natural language prompt to your AI client (e.g., "Show me all high-priority tickets for contacts in the West region").
The agent runs the necessary tools, pulls data from HRIS, CRM, ATS, or Ticketing, and provides you with one unified response.
Who is this actually for?
This is for Product Managers who need to audit how different systems connect. It's also essential for RevOps or HR Analysts tired of manually pulling data from four separate dashboards just to generate a single report. If you spend time copying and pasting data between Salesforce, Workday, and Zendesk, this saves your sanity.
Uses the API to correlate sales contact lists (CRM) with employee status (HRIS), verifying clean data before a major quarterly review.
Verifies that unified data schemas work across multiple categories, testing if CRM contacts match HRIS company structures without manual API logging.
Runs reports to get a combined list of active employees and associated organizational companies from the HRIS integration in seconds.
What Changes When You Connect
Correlate employee records and contacts. Instead of checking Workday, then Salesforce, you ask the agent for "all employees who are also key contacts." It runs list_employees and list_contacts, giving you a single list that cross-references both sources.
Track candidates through the entire lifecycle. You can get status updates on applications (list_applications) and see which candidates are flagged as high potential (list_candidates), all without leaving your chat window.
Get full visibility into customer issues. Running list_tickets provides a real-time snapshot of open support tickets, allowing you to immediately prioritize based on issue type or client account found in the CRM data.
Verify integration health instantly. Use get_account_details to audit your linked workspace and see exactly which systems are connected and what boundaries the API can touch—no manual setup checks required.
Standardize reporting across silos. By unifying access, you stop dealing with proprietary formats. You get a standardized data structure whether the information came from an HRIS or an ATS.
See it in action
Checking candidate overlap
A recruiter needs to know if a high-potential job applicant (ATS) already exists as a sales contact in the CRM. They ask the agent, "Cross-reference candidates with our top contacts." The system runs list_candidates and compares results against list_contacts, solving the manual spreadsheet matching problem.
Post-onboarding data audit
A Product Manager needs to verify that every new employee (HRIS) has a corresponding account record (CRM). They prompt, "Show me all employees without an associated CRM account." The agent runs list_employees and then checks for matches in list_accounts, instantly identifying gaps.
Triaging a critical customer issue
A support lead receives a ticket (Ticketing). They ask the agent to look up the client's history. The system runs list_tickets and uses that account ID to pull related contact details from the CRM (list_contacts), giving immediate context.
Reviewing company structure changes
An executive wants to see how many people (HRIS) are working for companies listed in the CRM. The agent executes list_companies and compares the resulting list against the data from list_employees, providing a clean headcount report.
The honest tradeoffs
The Dashboard Hop
Pulling reports by manually logging into Workday, then Zendesk, then Salesforce, and finally compiling the data in Excel. This takes hours and is prone to human error.
Ask your AI agent for a summary report. The agent handles the multi-system call automatically, running list_employees, list_tickets, and others, giving you one consolidated JSON output.
The Point-to-Point Script
Writing 4 separate API endpoints—one for HRIS data, one for CRM data, etc.—and then building the logic to combine them in your own backend code.
Use Merge. The server already handles the complex plumbing and standardization between systems; you just need to call the relevant tools conversationally.
The Over-Fetch
Requesting every single field for every employee when you only needed their name and department.
Be specific in your prompt. Ask, "List the names and departments of employees who are also contacts." This limits the scope and prevents unnecessary data retrieval.
When It Fits, When It Doesn't
Use this MCP Server if your core problem is data correlation or cross-platform reporting. Specifically, use it when you need to answer questions like, "Which candidates in the ATS have current support tickets?" You rely on its tools (list_candidates, list_tickets) to bridge gaps between otherwise separate systems.
Don't use this if your task is simple data transformation (e.g., changing date formats) or complex business logic that requires decision-making between the retrieved data sets. If you need real-time, transactional synchronization—where an action in System A must immediately trigger a specific record update in System B—you should look into dedicated event streaming platforms or middleware solutions instead.
Questions you might have
Can I use list_employees to find people who are also CRM contacts? +
Yes. You ask your agent for a cross-reference query (e.g., "List employees who match any records in the CRM"). The server uses list_employees and compares that output against data pulled from list_contacts.
Does list_tickets include historical or just open support tickets? +
The tool retrieves both inbound and outbound support tickets. You can refine your prompt to specify if you only want 'open' issues, helping the agent filter the data for you.
What is the difference between list_candidates and list_applications? +
list_candidates gives a roster of people tracked in your ATS. list_applications provides specific records detailing job submissions, showing which roles they applied for.
Is getting account details the same as listing accounts? +
No. get_account_details checks the connection's overall configuration and boundaries. list_accounts actually retrieves a list of specific customer records from the CRM integration.
If I update my credentials, how do I verify changes using get_account_details? +
You must use get_account_details after updating your API key or token. This tool lets you inspect the current integration boundaries and ensures your agent is pointing to the correct data source immediately.
When I run list_employees, how does the system handle pagination for large organizations? +
The MCP server handles pagination automatically. If there are thousands of records, your AI client doesn't just get the first page; it loops through all necessary API calls to pull every available employee record.
Does list_candidates have visibility into rejected applicants or only active ones? +
The list_candidates tool pulls data based on what your ATS integration exposes, typically including both active and historical records. You can filter the results within your AI client to focus only on specific statuses.
If list_contacts fails due to a CRM service outage, does it affect other tools? +
No. The MCP server isolates tool calls. If list_contacts throws an error, your agent will report that failure clearly without affecting the ability to run commands like list_tickets or list_companies.
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.
