Updating an Existing MCP Server

​
Using HasMCP UI

Server Edit Page To modify an existing MCP server through the dashboard:
  1. Navigate to the Servers page from the sidebar.
  2. Click on the server you want to update to open its details.
  3. Click the Edit button in the top right corner.
  4. Modify properties like the name or instructions, and hit Save to apply your changes.

​
Using REST API

To modify the properties, instructions, or associated components of an existing MCP server programmatically, use the PATCH method against the server’s specific API endpoint.

​
Update Endpoint Route

PATCH /servers/{id}

​
The Update Process

  1. Identify the Server ID: Find the 11-character identifier of your target server (e.g., kSuB9Gf6aD4).
  2. Construct the Update Payload: The JSON body should conform to the UpdateServerRequest schema.
  • Update string fields such as name or instructions.
  • Update associations by passing lists containing the desired providers, resources, or prompts.

​
Example cURL Update

curl -X PATCH https://app.hasmcp.com/api/v1/servers/kSuB9Gf6aD4 \
 -H "Authorization: Bearer YOUR_TOKEN" \
 -H "Content-Type: application/json" \
 -d '{
 "server": {
 "name": "updatedServerName",
 "instructions": "New and varied instructions."
 }
 }'
If successful, the API returns a 200 OK response with the newly updated Server object.
