What transkribus_coll_update_default_tag_defs does on Transkribus
AI agents use transkribus_coll_update_default_tag_defs to create or update resources in Transkribus, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Transkribus environment.
Why transkribus_coll_update_default_tag_defs is rated Medium
This tool creates or modifies data (tag definitions) across all collections. It is reversible (tags can be updated again), so it is Write rather than Destructive. However, the global scope and potential to affect all downstream tagging workflows across an organization elevates severity to high.
From the tool's definition 'Update the default tag definitions across all collections' — this modifies tag definitions that apply globally across all collections, a configuration that affects multiple collections permanently.

The rule that runs transkribus_coll_update_default_tag_defs safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Transkribus, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For transkribus_coll_update_default_tag_defs, this is the rule to start with:
transkribus_coll_update_default_tag_defs stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Transkribus, apply this rule, and every transkribus_coll_update_default_tag_defs call is checked against it from then on.
