WHAT IT DOES

What collections_add_file does on Dialogbrain

AI agents use collections_add_file to create or update resources in Dialogbrain, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Dialogbrain environment.

Parameter	Type	Required	Description
`file_id`	integer	Yes	ID of the file to add (from files_upload)
`collection_id`	integer	Yes	ID of the collection

Parameters from the server's own tool schema.

RISK

Why collections_add_file is rated Medium

This tool modifies data (a knowledge collection) by adding or re-enabling file associations. It is reversible (files can be removed), so it falls under Write rather than Destructive. Severity is medium because unauthorized addition of files to collections could pollute knowledge bases or expose sensitive information to AI agents, but the impact is localized to the collection and reversible.

From the tool's definition Tool 'collections_add_file' creates or modifies a knowledge collection by adding a file to it. Description states it 'Add[s] a file to a knowledge collection' and can 're-enable' previously removed files, indicating reversible state changes.

RECOMMENDED RULE

The rule that runs collections_add_file safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Dialogbrain, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For collections_add_file, this is the rule to start with:

collections_add_file Rate-limited

collections_add_file 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 Dialogbrain, apply this rule, and every collections_add_file call is checked against it from then on.
