AI agents call search_legislation to retrieve information from Icelandic Law 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 search_legislation 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.

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so search_legislation only ever does what you allow.

What does the search_legislation tool do? +

Search Icelandic statutes (lög) and regulations by keyword. Searches provision text using FTS5 full-text search with BM25 ranking. Supports boolean operators (AND, OR, NOT), phrase search ("exact phrase"), and prefix matching (term*). Returns matched provisions with snippets, relevance scores, and document metadata. Icelandic law numbers use the format number/year (e.g., "90/2018" for Persónuverndarlög). When NOT to use: If you already know the exact law number and provision, use get_provision instead.. It is categorised as a Read tool in the Icelandic Law MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on search_legislation? +

Register the Icelandic Law MCP server in PolicyLayer and add a rule for search_legislation: 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 Icelandic Law. Nothing to install.

What risk level is search_legislation? +

search_legislation is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit search_legislation? +

Yes. Add a rate_limit block to the search_legislation 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.

How do I block search_legislation completely? +

Set action: deny in the PolicyLayer policy for search_legislation. 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.

What MCP server provides search_legislation? +
