AI agents call scope_credential_alerts to retrieve information from Scope (AEC) - Preview 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 scope_credential_alerts 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.

Vendors with expiring or expired credentials. Filtered version of scope_vendor_health. Use for compliance review or for the morning briefing's 'what needs attention' list.. It is categorised as a Read tool in the Scope (AEC) - Preview MCP Server, which means it retrieves data without modifying state.
Register the Scope (AEC) - Preview MCP server in PolicyLayer and add a rule for scope_credential_alerts: 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 Scope (AEC) - Preview. Nothing to install.
scope_credential_alerts 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 scope_credential_alerts 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 scope_credential_alerts. 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.
scope_credential_alerts is provided by the Scope (AEC) - Preview MCP server (scope-bid/scope-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
