AI agents call find_semantic_software to retrieve information from Schema Gov It MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing metadata from a public catalog. It has no side effects, does not create, modify, or delete data, and does not execute code or trigger external operations. The search functionality is read-only information retrieval, making it a Read category tool with low severity due to its informational nature and lack of blast radius.
From the tool's definition Tool performs a 'Search' operation on the Open Knowledge Graphs catalog for semantic web software tools. The description explicitly states it searches and indexes metadata, with no modification, deletion, or execution capabilities mentioned.
Documented attack patterns abuse exactly the kind of access find_semantic_software gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Schema Gov It MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for find_semantic_software:
{
"version": "1",
"default": "deny",
"tools": {
"find_semantic_software": {}
}
} find_semantic_software is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Schema Gov It MCP Server MCP server in PolicyLayer and add a rule for find_semantic_software: 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 Schema Gov It MCP Server. Nothing to install.
find_semantic_software 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 find_semantic_software 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 find_semantic_software. 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.
find_semantic_software is provided by the Schema Gov It MCP Server MCP server (italia/dati-semantic-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Schema Gov It MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
