Dry-run validation for create_account — does not write to the DB.
AI agents call validate_account_payload to retrieve information from FixPayment without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs input validation without side effects. It checks the format and structure of account creation data but explicitly does not persist any changes to the database. This is a read-only operation that retrieves validation results, making it fall under the Read category with low severity since misuse would only affect the validation output, not actual account data or financial operations.
From the tool's definition Tool description explicitly states 'Dry-run validation for create_account — does not write to the DB.' This confirms no data modification occurs.
Attacks that exploit this kind of access
Dry-run validation for create_account — does not write to the DB. It is categorised as a Read tool in the FixPayment MCP Server, which means it retrieves data without modifying state.
Register the FixPayment MCP server in PolicyLayer and add a rule for validate_account_payload: 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 FixPayment. Nothing to install.
validate_account_payload 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 validate_account_payload 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 validate_account_payload. 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.
validate_account_payload is provided by the FixPayment MCP server (prmail/fixpayment_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
validate_account_payload is one line of FixPayment's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
