Hi

I tried to use the PD MCP in VSCODE for auto create Schedule Overides but I’m always getting the error: “Sorry, no response was returned.”

 

My MCP config is below:

"io.github.PagerDuty/pagerduty-mcp": {

"type": "stdio",

"command": "uvx",

"args": [

"pagerduty-mcp==0.2.1",

"--enable-write-tools"

],

 

“Get” operations are working fine.

 

My request is:

 

schedule_id: "P76S19G"
override_request: {
  "start": "2026-02-08T18:00:00+02:00",
  "end": "2026-02-09T08:00:00+02:00",
  "user": {
    "id": "PNBBMSL",
    "type": "user_reference"
  },
  "time_zone": "Asia/Jerusalem"
}

 

will appreciate any help here

Hi ​@yirmio thank you very much for raising this issue, we’ve tried to replicate the issue and it turned out that this issue is more related with a Model misuse of the tool, because We tested with Sonnet 4.5 and it didn’t go well, but after testing it with GPT 5 and Gemini 3, they both understood the PD tool instructions.

 

Therefore, we’ll have to enhance this specific tool instructions for models looking to improve model tool use. Expect to see this patched during next week. Thanks for the patience, please stay tuned.
