Modifying a Provider Tool

​
Using HasMCP UI

Edit Provider Tool Modal Updating a specific tool visually:
  1. From the Provider Details page, locate your target tool in the tool list.
  2. Click the Edit button contextually aligned with it.
  3. A modal will appear allowing you to alter the tool’s description, inputSchema, or execution path.
  4. Click Save to apply the configuration patch.

​
Using REST API

APIs evolve. If an endpoint changes its expected path parameters or if you wish to refine a tool description to get better LLM adherence, you can iteratively update a specific tool.

​
The API Endpoint

PATCH /providers/{providerId}/tools/{id}

​
Making the Patch Request

Send a request embedding the UpdateProviderToolRequest data payload. Only include the fields inside the tool object that you explicitly wish to modify—omitted fields will retain their existing configurations.

​
Example Update Request

curl -X PATCH https://app.hasmcp.com/api/v1/providers/kSuB9Gf6aD4/tools/tOlM8Hr2zP1 \
 -H "Authorization: Bearer YOUR_TOKEN" \
 -H "Content-Type: application/json" \
 -d '{
 "tool": {
 "description": "An UPDATED prompt for the LLM. Describe the query accurately.",
 "execution": {
 "method": "POST",
 "path": "/api/v3/customers/query"
 }
 }
 }'
If the syntax and schemas are valid, HasMCP responds with 200 OK signaling that all connected servers mapped to this tool will now utilize the updated configuration in real-time.
