Full-text search across the CSF framework with fuzzy matching
AI agents call search_framework to retrieve information from NIST CSF 2 0 Assessment Platform without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only searches and retrieves information from the NIST CSF framework. It does not create, modify, delete, or execute any operations. The fuzzy matching capability is a search refinement feature, not an execution of arbitrary code. The blast radius of misuse is minimal - an AI agent could retrieve framework information but cannot harm systems, data, or organizational security posture through search alone.
From the tool's definition Tool performs 'full-text search across the CSF framework with fuzzy matching' - a retrieval operation with no side effects or data modification.
Documented attack patterns abuse exactly the kind of access search_framework 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 search_framework:
{
"version": "1",
"default": "deny",
"tools": {
"search_framework": {}
}
}search_framework is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Full-text search across the CSF framework with fuzzy matching. It is categorised as a Read tool in the NIST CSF 2 0 Assessment Platform MCP Server, which means it retrieves data without modifying state.
Register the NIST CSF 2 0 Assessment Platform MCP server in PolicyLayer and add a rule for search_framework: 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.
search_framework is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the search_framework 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 search_framework. 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.
search_framework 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.
