What is your goal?
Our goal is to use Make MCP Server as a backend for ChatGPT, so that ChatGPT can:
● discover Make scenarios exposed as MCP tools
● invoke on-demand scenarios
● pass structured inputs
● receive structured outputs
In short: Make as an MCP-based function backend for LLM workflows.
What is the problem & what have you tried?
Hi everyone,
I’m starting this thread because I couldn’t find any existing discussion about this yet, and I suspect we’re not the only ones experimenting with this right now.
We’ve been testing the new Make MCP Server integration with ChatGPT, following the official developer documentation and recent webinar materials. Conceptually, the setup is very promising, but in practice we’re currently blocked by what looks like a platform-side limitation or rollout gap.
Below is a concise breakdown of what we tried, what works, and where it breaks down.
What we have set up successfully
● Make plan: Core (paid)
● MCP connection method: OAuth (via ChatGPT → Create App → Custom MCP Server)
● MCP Server URL: https://mcp.make.com
● OAuth authorization completes successfully (organization selected, scopes granted)
● MCP app is created and visible in ChatGPT Apps
● No errors during setup
Test scenario setup in Make
● We created a minimal test scenario:
● Trigger: Tools → Basic Trigger → On Demand
● Input defined on the trigger (e.g. echo_text as string)
● Output module added (e.g. Set Variable / Create JSON)
● Scenario is Active
● No schedule, no webhook, no watch triggers
This should be the simplest possible MCP-exposed scenario.
What does not work
● ChatGPT never actually executes the scenario
● No scenario runs appear in Make execution history
● No errors are shown in ChatGPT
● No MCP tool call is visible or implied
● Agent Mode in ChatGPT appears unstable:
●● task submission button often disabled (greyed out)
●● even valid task descriptions cannot be submitted
● Non-Agent chat also does not trigger MCP calls
From the user’s perspective, it looks like:
the MCP app is connected, but completely inert.
Observations / hypothesis
This does not look like a configuration issue on the Make side:
● Scenario structure matches MCP documentation
● OAuth completes successfully
● No validation errors anywhere
It currently feels more like:
● MCP tool execution is not yet enabled or feature-flagged on the ChatGPT side
● or Agent Mode + Custom MCP Servers are still partially rolled out / unstable
● or the ChatGPT UI allows MCP app creation before execution support is fully live
Questions for the community / Make team
-
Has anyone successfully executed a Make scenario via MCP from ChatGPT yet?
-
Is there a known limitation or rollout phase for ChatGPT MCP execution?
-
Are additional Make-side settings required that are not yet documented?
-
Is Basic Trigger (On Demand) the correct and supported approach for MCP tools?
If anyone has this working (or partially working), we’d love to hear details.
Thanks!
