AI agents call trust_get_score to retrieve information from Servicialo 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 trust_get_score 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.

Get the trust score of an organization from the Servicialo resolver. Use this to evaluate reliability before booking — returns score (0-100), trust level (unverified → declared → vouched → verified), and last activity timestamp. Do NOT use this to find organizations (use resolve.search). Trust accumulates passively from verified service history; it cannot be purchased or self-declared.. It is categorised as a Read tool in the Servicialo MCP Server, which means it retrieves data without modifying state.
Register the Servicialo MCP server in PolicyLayer and add a rule for trust_get_score: 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 Servicialo. Nothing to install.
trust_get_score 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 trust_get_score 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 trust_get_score. 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.
trust_get_score is provided by the Servicialo MCP server (@servicialo/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
