sf agent mcp update --label returns success but resets the label to the server name

[konkonrong-lgtm]

Summary

sf agent mcp update --label returns success, but doesn't persist the requested label.

A custom label works when the MCP server is created, but updating it later resets the label to the server name.

--description updates correctly on the same server.

I also reproduced the behavior with a direct PUT to the API Catalog endpoint, without using sf agent mcp update.

Steps To Reproduce

A repository is not required to reproduce this issue because the behavior occurs against an org-level API Catalog MCP server resource and can be reproduced directly with Salesforce CLI commands.

1. Create an MCP server with a custom label:

sf agent mcp create --name OssMcpLabelTest2 --label "Custom Create Label" --server-url "https://mcptest-daniel-e6e72a8eba7a.herokuapp.com/mcp" -o <target-org> --json

The server is created successfully and the response contains:

{
  "name": "OssMcpLabelTest2",
  "label": "Custom Create Label"
}

2. Update only the label:

sf agent mcp update --mcp-server-id <MCP_SERVER_ID> --label "Updated Label Test" -o <target-org> --json

The command succeeds with status: 0, but the returned server contains:

{
  "name": "OssMcpLabelTest2",
  "label": "OssMcpLabelTest2"
}

rather than the requested value:

{
  "label": "Updated Label Test"
}

3. Read the server again:

sf agent mcp get --mcp-server-id <MCP_SERVER_ID> -o <target-org> --json

The persisted value is still:

{
  "name": "OssMcpLabelTest2",
  "label": "OssMcpLabelTest2"
}

4. As a control, update the description:

sf agent mcp update --mcp-server-id <MCP_SERVER_ID> --description "OSS Description Test" -o <target-org> --json

A subsequent sf agent mcp get correctly returns:

{
  "description": "OSS Description Test"
}

5. I also reproduced the issue without using sf agent mcp update, by sending a raw PUT request directly to the API Catalog endpoint:

'{"label":"Raw Label Test"}' | sf api request rest '/services/data/v67.0/api-catalog/mcp-servers/<MCP_SERVER_ID>' --method PUT --header 'Content-Type: application/json' --body - -o <target-org>

The request succeeds, but the response again contains:

{
  "name": "OssMcpLabelTest2",
  "label": "OssMcpLabelTest2"
}

A subsequent:

sf agent mcp get --mcp-server-id <MCP_SERVER_ID> -o <target-org> --json

confirms that "Raw Label Test" was not persisted.

I reproduced the label update behavior with two separate MCP server registrations.

Expected result

Running:

sf agent mcp update --mcp-server-id <MCP_SERVER_ID> --label "Updated Label Test" -o <target-org> --json

should update and persist the MCP server label as:

{
  "label": "Updated Label Test"
}

Actual result

The command returns success, but the requested label is not persisted.

Instead, the label becomes equal to the MCP server's name:

{
  "name": "OssMcpLabelTest2",
  "label": "OssMcpLabelTest2"
}

The same behavior occurs when sending the update directly to the API Catalog REST endpoint with a raw PUT request.

Additional information

• Reproduced with two MCP server registrations.
• Custom labels work on create.
• Description updates work correctly.
• The same label behavior occurs with a direct REST PUT.
• sf doctor was run before filing; no related diagnostic problems were reported.
• agent mcp is currently in Developer Preview.
