Install the Transform MCP server

Install the Unstructured Transform MCP server by using these instructions: 
https://docs.unstructured.io/transform/install/postman.md

1. From your terminal, authenticate with the Transform MCP server:
   npx -y mcp-remote https://mcp.transform.unstructured.io
   
   A web browser tab will appear, prompting you to authenticate with Transform. Follow the on-screen directions to finish authenticating.
2. After you authenticate, back in your terminal, press Ctrl + C to exit and return to your terminal prompt.
3. Start the Postman Desktop Agent app.
4. If you are not already signed in to Postman, in the Desktop Agent’s title bar, click Sign in, and follow the on-screen directions to finish signing in.
5. In Desktop Agent’s title bar, in the Search box, enter Unstructured.
6. For filters, select Visibility: Public and Type: Workspace.
7. In the list of search results, select Unstructured’s Workspace.
8. On the sidebar, with the Collections panel expanded, and with the Unstructured Transform MCP Server Collection node expanded within this panel, click Unstructured Transform MCP Server.
9. On the Unstructured Transform MCP Server tab, click Connect. If prompted, select All requests in this collection, and then click Grant access.
10. If a Connection failed or similar message appears, go back to your terminal and run the preceding npx command again, and then click Connect again.
11. After the Unstructured Transform MCP Server shows as Connected with a green circle icon, on the sidebar, click Unstructured Transform MCP Server Request.
12. On the Unstructured Transform MCP Server Request tab, click Tools.
13. If Disabled appears, turn on the toggle to show Tools enabled with a green circle icon. If this does not work, go back to your terminal and run the preceding npx command again, and then turn on the toggle again.
14. In the Add server box, enter the following command, replacing </path/to/local/folder> with the path to the local folder where the files you want Transform to parse are stored:
    npx -y @modelcontextprotocol/server-filesystem </path/to/local/folder/>
    
    
15. Click Add server. It will also show Tools enabled with a green circle icon.
16. The Transform MCP server is ready for you to start using.

Parse your source files

• Each file must be of a supported file type.
• Each file must be 50 MB or less in size.
• Each request must have 10 files or fewer.
• Only 5 requests can be running at a time.

1. After you install the Transform MCP server, make sure the Unstructured Transform MCP Server Request node is already expanded from the previous section.
2. On the Prompt tab, in the New user prompt area, enter the following prompt:
   Use the MCP Transform Unstructured server to parse the files in this folder.
   
   Provide the results as downloadable JSON files, one JSON file per source file.
   
   Note that in the preceding prompt, in this folder refers to </path/to/local/folder/> that you specified in the previous section.

3. In Select a provider or enter URL, select an AI provider and model that you want to use for this AI session. To learn more about this setting, see Create a new AI request in the Postman documentation.
4. If your selected model requires you to provide an API key, click the Authorization tab and follow the on-screen directions.
   This is the API key for your selected model’s provider. This is not your Unstructured API key.
5. Click Send, and follow the agent’s on-screen directions. This will involve the agent asking you to run one or more curl commands yourself to upload your source files to Transform, as well as clicking one or more download links to download Transform’s output JSON files based on your original source files. To respond to the agent or ask follow-up questions at any point, continue typing in the New user prompt area mentioned in step 2. For example:
