AI agents use record_gap to create or update resources in NIST CSF 2 0 Assessment Platform — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your NIST CSF 2 0 Assessment Platform environment.
This tool creates or modifies gap analysis data within the assessment platform, which is a reversible write operation. It does not delete data (would be Destructive), does not execute arbitrary code (would be Execute), involves no financial transactions (would be Financial), and is not a simple read/query operation (would be Read).
From the tool's definition Tool name 'record_gap' and description 'Record gap analysis for a category' indicate a write operation that creates or stores gap analysis records.
Documented attack patterns abuse exactly the kind of access record_gap gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and NIST CSF 2 0 Assessment Platform, and nothing reaches the server without passing your rules. This is the rule we recommend for record_gap:
{
"version": "1",
"default": "deny",
"tools": {
"record_gap": {
"limits": [
{
"counter": "record_gap_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}record_gap 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.
Free to start. No card required.
Record gap analysis for a category. It is categorised as a Write tool in the NIST CSF 2 0 Assessment Platform MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the NIST CSF 2 0 Assessment Platform MCP server in PolicyLayer and add a rule for record_gap: 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 NIST CSF 2 0 Assessment Platform. Nothing to install.
record_gap is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the record_gap 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.
Set action: deny in the PolicyLayer policy for record_gap. 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.
record_gap is provided by the NIST CSF 2 0 Assessment Platform MCP server (rocklambros/nist-csf-2-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
