AI agents call get_public_obligations to retrieve information from Mcp 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 get_public_obligations 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.

Retrieve the universal obligation set for a Norwegian entity type. Returns every regulatory obligation that applies by virtue of an entity BEING that organisational form, BEFORE per-company Tier-2 data (employee count, MVA registration, turnover) is layered on. Use this tool when an agent wants to answer 'what does an AS owe?' or 'what are the baseline filings for an Enkeltpersonforetak?' without naming a specific company. Each obligation in the response carries a tier_2_required boolean — true means the rule engine needs commercial data to know whether the obligation actually applies to a SPECIFIC company (e.g. MVA / VAT registration only applies above the NOK 50,000 turnover threshold), false means the obligation applies unconditionally to every entity of that type. Common Norwegian regulatory concepts surfaced in the response include MVA / VAT (Merverdiavgift, Norwegian value-added tax), A-melding (the monthly employer payroll report consolidating tax + payroll-tax + pension data), Aksjonærregisteret (shareholder register filing), and Årsregnskap (annual accounts). Input: { entity_type } from the closed enum AS / ASA / ENK / DA / ANS / SAMVIRKE / STIFTELSE / NUF / OFFENTLIG. For per-company evaluation that DOES layer on commercial data, call get_company_obligations. Failure modes the agent must handle: VALIDATION_FAILED on an unknown entity_type (the enum is closed; there is no 'OTHER' fallback); SCOPE_INSUFFICIENT if the API key is not scoped read:rulebook; UPSTREAM_TIMEOUT on rulebook latency.. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for get_public_obligations: 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. Nothing to install.
get_public_obligations 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_public_obligations 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_public_obligations. 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_public_obligations is provided by the MCP server (https://www.apier.no/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
