get_changed_vector_data

Single-target operation

Part of the Statistics Canada MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

// WHEN AI AGENTS USE THIS TOOL

AI agents call get_changed_vector_data to retrieve information from Statistics Canada 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.

// WHY ENFORCE A POLICY ON GET_CHANGED_VECTOR_DATA

Even though get_changed_vector_data 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.

// RECOMMENDED POLICY

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

What does the get_changed_vector_data tool do? +

Get changed/updated data for a specific Statistics Canada vector. Returns the latest changes for a vector if it was updated today. :param vector_id: The vector ID number (e.g., 32164132) :return: Dictionary with changed vector data or error details . It is categorised as a Read tool in the Statistics Canada MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_changed_vector_data? +

Add a rule in your Intercept YAML policy under the tools section for get_changed_vector_data. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Statistics Canada MCP server.

What risk level is get_changed_vector_data? +

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

Can I rate-limit get_changed_vector_data? +

Yes. Add a rate_limit block to the get_changed_vector_data 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.

How do I block get_changed_vector_data completely? +

Set action: deny in the Intercept policy for get_changed_vector_data. 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 get_changed_vector_data? +

get_changed_vector_data is provided by the Statistics Canada MCP server (pranaviate/statscan-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
