Actionstep MCP Server — Release Notes

Checking your MCP Server Version

To check which version of the Actionstep MCP Server you are running, simply ask your AI Agent:

"What version of the Actionstep MCP server am I running?"

It will respond with the current version number similar to the following example:

"You're running actionstep-mcp-server version 1.18.0 (build commit 0c58071)"

NB: This feature is available from v1.18.0 onwards.

What's New in v1.18.3

Released 4 October 2026

• "Everything except…" searches now work. Filters that excluded something — for example matters that aren't a particular type, or tasks whose status isn't Closed — could come back with an error. Behind the scenes your assistant was using a "not equal to" symbol that Actionstep doesn't accept. We now use the correct one and automatically correct the old one if it slips through, so these exclusion searches succeed first time instead of failing.

What's New in v1.18.2

Released 28 September 2026

• Fewer failed filtered searches. Some advanced filters could fail when the wording sent by your assistant contained characters that had been converted to their web-safe form (for example a >= arriving as >=). We now recognise and correct these automatically, so those searches succeed instead of returning an error.

What's New in v1.18.1

Released 19 September 2026

• More reliable searches and filters. Narrowing results — by status, date, name, and so on — now works correctly the first time, so you'll hit far fewer failed or empty searches when filtering matters, contacts, tasks, and file notes. You can also now filter on a wider range of fields than before.

• No more unexpected sign-outs during busy sessions. We fixed a rare issue where several actions running at once could sign you out and make you reconnect. Your session now stays put through bursts of activity.

What's New in v1.18.0

Released 16 September 2026

• Complete lists, every time. We fixed cases where long lists could stop short. Most noticeably, custom-field listings on a matter or contact now return every entry instead of capping at the first 50. Very large result sets can also be retrieved a page at a time.

• Check your version in a click. You can now just ask "What version of the Actionstep MCP server am I running?" and get a clear answer — handy for confirming a release includes the fixes you asked for.

• More complete date filters on file notes. Filtering file notes by date now also picks up system-generated notes (such as custom-field change entries) that could previously be missed.

• Clearer "nothing found" responses. A search that matches no records now says so plainly, rather than returning an ambiguous empty result.

• More accurate guidance. The assistant no longer suggests actions that aren't switched on in this release, so you won't be pointed toward features that aren't available yet.
