AI agents call devops_check_certs to retrieve information from Devops Status Mcp Server 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 devops_check_certs 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.

Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Inspect SSL/TLS certificate health for one or more domains by performing a real TLS handshake. Works for any internet-accessible domain — no vendor registry required. Reports days to expiry (flagged at < 30 days warning and < 7 days critical), certificate subject and SANs, issuer, chain depth, TLS protocol version negotiated (flags TLS 1.0/1.1 as insecure), cipher suite, and HSTS presence.. It is categorised as a Read tool in the Devops Status Mcp Server MCP Server, which means it retrieves data without modifying state.
Register the Devops Status Mcp Server MCP server in PolicyLayer and add a rule for devops_check_certs: 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 Devops Status Mcp Server. Nothing to install.
devops_check_certs 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 devops_check_certs 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 devops_check_certs. 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.
devops_check_certs is provided by the Devops Status Mcp Server MCP server (@cyanheads/devops-status-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
