Look up the risk score for a contact identifier (email or phone). Use for account-takeover screening at login or password reset.
AI agents call get_score_by_contact to retrieve information from Mcp Ap2 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries existing risk score data based on contact identifiers (email or phone). It has no capability to modify data, execute code, delete records, or commit financial transactions. While it is used in a security-sensitive context (account-takeover screening), the tool itself only reads information.
From the tool's definition Tool performs a 'Look up' operation to retrieve a risk score for a contact identifier. Description explicitly states it is used for 'screening' (query/check), not modification or execution.
Documented attack patterns abuse exactly the kind of access get_score_by_contact gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for get_score_by_contact:
{
"version": "1",
"default": "deny",
"tools": {
"get_score_by_contact": {}
}
}get_score_by_contact is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Look up the risk score for a contact identifier (email or phone). Use for account-takeover screening at login or password reset. It is categorised as a Read tool in the Mcp Ap2 MCP Server, which means it retrieves data without modifying state.
Register the Mcp Ap2 MCP server in PolicyLayer and add a rule for get_score_by_contact: 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 Mcp Ap2. Nothing to install.
get_score_by_contact 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_score_by_contact 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_score_by_contact. 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_score_by_contact is provided by the Mcp Ap2 MCP server (@codespar/mcp-ap2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Ap2, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
