AI agents call check_bulk_dph_payer to retrieve information from Adis 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 check_bulk_dph_payer 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.

Bulk reliability check for up to 100 Czech subjects in one ADIS request. Lighter than the single-subject check — returns reliability status, accounts, and tax office, but no name/address. Useful for screening invoice-issuer lists or supplier portfolios. Returns one entry per input DIČ; entries with reliability NENALEZEN indicate the subject is not in the VAT registry.. It is categorised as a Read tool in the Adis MCP Server, which means it retrieves data without modifying state.
Register the Adis MCP server in PolicyLayer and add a rule for check_bulk_dph_payer: 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 Adis. Nothing to install.
check_bulk_dph_payer 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 check_bulk_dph_payer 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 check_bulk_dph_payer. 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.
check_bulk_dph_payer is provided by the Adis MCP server (@czagents/adis). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
