Jotform MCP Connector: All endpoints failing with tool execution errors

Hi team,

I'm using the JotForm MCP connector in Claude Cowork and all three available tool endpoints have been returning tool execution failures since approximately mid-day on April 19, 2026. The issue is consistent across multiple attempts over several hours.

Affected tools:

• create_form — fails on every attempt, including minimal single-line descriptions
• edit_form — was working earlier today (successfully added fields to form ID 261076976733064 around midday), then stopped responding entirely
• fetch — fails on both valid form IDs and fresh attempts

What we were trying to do:

• Fetch metadata from an existing form (261076976733064) to confirm its current state
• Create a new multi-page form via create_form
• Edit the existing form via edit_form as a fallback when create_form failed

Error returned: Tool execution failed. You can try again. — no additional detail, no HTTP status code surfaced to the agent.

What we've ruled out:

• JotForm's own infrastructure — status.jotform.com shows all systems operational (Forms, API, Submission Service all green)
• Description length — create_form was tested with a single sentence and still failed
• Form-specific issues — fetch fails on a known valid form ID that was successfully accessed hours earlier

Context:

• The connector worked correctly earlier today — edit_form successfully added 10 fields to form 261076976733064
• The failure appears to have started after a period of inactivity, possibly a session/token expiry or a dropped connection on the MCP server side
• No changes were made to credentials, settings, or the plugin between the working and non-working states

Request: Can you check whether the MCP server process needs a restart, whether there's a session token that's expired, or whether there's a known issue with the connector? Happy to provide any additional logs or form IDs needed to reproduce.

Thanks!

Hi Devin,

Thanks for reaching out to Jotform Support. As a troubleshooting step, we can try re-authenticating the connector between your Claude and Jotform. This can be done in your Claude account, through the connectors or plugins menu. Try disconnecting the Jotform connector and adding it back. This will force a new OAuth handshake and generate a fresh access token.

Also, can you log into your Jotform account and go to Settings > API > Authorized Apps? Check if Jotform MCP appears there. If it does, try deleting that specific authorization and then reconnecting through Claude.

Once done, try operating your Jotform account through Claude again and see how it goes. If the same thing happens again, let us know, and we can investigate what's happening further.

Keep us updated and let us know if you need any help.
