Hi, I am trying to use Claude to automate CRM process and came across a problem on Decile MCP. I've reported this(#122431). When will you fix it and notify me? Thank you!!!

Minimal repro: Decile MCP write endpoints fail due to missing top-level array envelope

Summary

Decile MCP read endpoints work, but multiple write endpoints fail with the same validation error indicating the wrapper is not nesting records under the required top-level key.

Environment
- Toolkit: Decile MCP
- Auth: valid
- Confirmed working reads: list_people, check_api_key_status, debug_api_request

Repro 1: createorupdate_person
Input:
json
{
"first_name": "Test",
"last_name": "User",
"email": "test@example.com"
}

Actual error:
text
param is missing or the value is empty or invalid: people


Repro 2: createorupdate_prospect
Actual error:
text
param is missing or the value is empty or invalid: prospects


Repro 3: createmultipleprospects
Actual error:
text
param is missing or the value is empty or invalid: prospects


Expected behavior

Wrapper should send:
json
{ "people": [ ... ] }

or
json
{ "prospects": [ ... ] }


Likely root cause

MCP wrapper posts record fields flat instead of wrapping them in the API’s required envelope.

Hey Pamela, thanks for the report on this. We'll update the MCP instructions to be a bit more clear on the field wrapping.

Hey  @Pamela Hsieh , sorry for the delayed response. Over the last 2 weeks we been doing major updates to the MCP, including bringing it into the fold at decilehub.com/mcp instead of its own domain.

Please check https://decilehub.com/api/settings to get a new API token and get the new MCP instructions as well. This is an area of significant focus for us right now, and we are adding/improving the new MCP daily.
