AI agents call get_provider to retrieve information from Xcircl Agent without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves provider information from a regulated-care provider data API using an entity_id parameter. It performs a read-only query with no side effects, no code execution, no data modification, and no destructive or financial operations.

Fetch a single provider by entity_id (e.g. It is categorised as a Read tool in the Xcircl Agent MCP Server, which means it retrieves data without modifying state.
Register the Xcircl Agent MCP server in PolicyLayer and add a rule for get_provider: 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 Xcircl Agent. Nothing to install.
get_provider 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 get_provider 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 get_provider. 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.
get_provider is provided by the Xcircl Agent MCP server (25cy/xcircl-agent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_provider is one line of Xcircl Agent's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
