Release R26-5 #
Available from 11th May 2026
Highlights #
Accounts > OAuth Client Credentials – available to all Consoles
The Account-level OAuth Client Credentials feature – used to secure both MCP Servers (when the feature is enabled) and Webhooks – is now available as a standard feature in all Consoles.
Console > Template Library / Accounts > Cycles – multiple levels of folders
You can now create folders within folders, in both the Template Library and your Accounts.
Also, when searching for Templates or Cycles, the location within any folders is shown, to help you identify where the matches were found.
Cycle Execution > Webhooks – “+json” Content-Types now accepted
Cyclr now accepts requests to its Webhook Steps which use a Content-Type HTTP Header containing “+json” as JSON data, e.g. application/...+json.
MCP Servers – can now use your Custom Connectors
When you have MCP Servers enabled on your Cyclr Console, you’re no longer restricted to using Application Library Connectors, but can also use Custom Connectors that you’ve created.
MCP Servers – exposing Tasks and other details
When you have MCP Servers enabled on your Cyclr Console, a number of details are now shown in Cyclr’s interface, to help you identify activity and usage of your MCP tools.
Improvements #
Custom Connectors > Script – new auth_unique_identifer Script variable
Script functions now have an auth_unique_identifer variable available. It contains the Unique Identifier of the currently selected Authentication Type used on an installed Connector. This enables you to write Script that can decide what action to take if it’s dependent on the Authentication Type in use.
Cycle Execution – resolved data being identified as empty
In some situations, it was possible for data returned when Cyclr made a call to an eternal system to appear blank, resulting in an erroneous “Response data fields missing“ Step Warning being recorded. That was quickly identified and resolved.
Cycle Execution – “Wait Until” Steps show a Step Error if parameter missing
If a Wait Until Step uses a value mapped from a previous Step, but no value is provided during Transaction execution, a Step Error will now be logged for it.
Cycle Execution > Webhook Replaying – resolved missing Webhook data
Corrected Webhook data missing when using the Replay Transaction option.
