# Create Mapping Between Systems

### Description

A user wants to create a new field mapping between entity types of two systems — for example, mapping Jira Issues to Rally Defects.

### Example interaction

| Component               | Detail                                                                                                                                                      |
| ----------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **User prompt**         | "Create a mapping between Jira Issues and Rally Defects for the Alpha (Jira) - Beta (Rally) project integration."                                           |
| **MCP tools invoked**   | `mapping_planner` → `get_fields_meta` (for both systems) → `create_mapping`                                                                                 |
| **AI assistant steps**  | Retrieves field metadata for both entity types → checks for duplicate mappings → presents proposed mapping for user confirmation → creates on confirmation. |
| **AI assistant output** | Confirmation of the created mapping with its ID and a summary of the fields mapped.                                                                         |

### Notes

* The AI assistant will always check for existing mappings before creating and will warn of potential duplicates.
* Advanced configurations such as XSLT transformations, conflict detection rules, and overwrite settings can be applied by requesting them in your prompt.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.opshub.com/v7.237/manage/mcp/mcp-sample-use-cases/mcp-use-case-create-mapping.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
