WHAT IT DOES

What integrity does on Defense

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

Parameter	Type	Required	Description
`name`	string	—	Baseline name
`paths`	object	—	File path(s) to check (string or array)
`quick`	boolean	—	Quick scan, skip database updates
`quiet`	boolean	—	Only show infected findings
`action`	string	Yes	Integrity monitoring action
`config`	string	—	Custom AIDE config file path
`dryRun`	boolean	—	Preview only
`expert`	boolean	—	Show additional diagnostic info
`dry_run`	boolean	—	Preview without executing
`directories`	array	—	Directories to hash
`update_first`	boolean	—	Update rkhunter database before scanning
`baseline_path`	string	—	Baseline hash file for comparison

Parameters from the server's own tool schema.

RISK

Why integrity is rated Medium

An AI agent can call integrity faster than any human can review: one bad instruction and it creates or modifies resources in Defense by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs integrity safely

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

integrity Rate-limited

integrity 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.

FAQ

Questions about integrity

What does the integrity tool do? +

Integrity: AIDE, rootkit scanning, file hashing, drift baselines. It is categorised as a Write tool in the Defense MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does integrity accept? +

integrity accepts 12 parameters: name, paths, quick, quiet, action, config, dryRun, expert, dry_run, directories, update_first, baseline_path. Required: action. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on integrity? +

Register the Defense MCP server in PolicyLayer and add a rule for integrity: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Defense. Nothing to install.

What risk level is integrity? +

integrity is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit integrity? +

Yes. Add a rate_limit block to the integrity rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block integrity completely? +

Set action: deny in the PolicyLayer policy for integrity. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides integrity? +

integrity is provided by the Defense MCP server (defense-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
