Part of the Canadian Law MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call search_legislation to retrieve information from Canadian 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.

Search Canadian federal statutes and regulations by keyword using full-text search (FTS5 with BM25 ranking). Returns matching provisions with document context, snippets with >>> <<< markers around matched terms, and relevance scores. Supports FTS5 syntax: quoted phrases ("exact match"), boolean operators (AND, OR, NOT), and prefix wildcards (term*). Results may be in English or French depending on available translations. Default limit is 10 results. For broad topics, increase the limit. Do NOT use this for retrieving a known provision — use get_provision instead.. It is categorised as a Read tool in the Canadian Law MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for search_legislation. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Canadian Law MCP server.
search_legislation 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 search_legislation rule in your Intercept 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 Intercept 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.
search_legislation is provided by the Canadian Law MCP server (@ansvar/canadian-law-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
