AI agents call view to retrieve information from Mitre Cwe without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though view only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access view gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
"Top 25 most dangerous software weaknesses" / "OWASP Top 10 CWE mapping" / "CWE view [N]" — fetch a curated CWE view (a published, opinionated selection of weaknesses). View 1003 = simplified mapping (NVD uses this), view 1387 = Top 25, view 1344 = OWASP Top 10. Returns the view's metadata plus the included CWE IDs.. It is categorised as a Read tool in the Mitre Cwe MCP Server, which means it retrieves data without modifying state.
Register the Mitre Cwe MCP server in PolicyLayer and add a rule for view: 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 Mitre Cwe. Nothing to install.
view 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 view 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 view. 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.
view is provided by the Mitre Cwe MCP server (https://gateway.pipeworx.io/mitre-cwe/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
