get_viewport_screenshot
Capture a screenshot of the 3D viewport
Part of the Blender MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
WHEN AI AGENTS USE THIS TOOL
AI agents call get_viewport_screenshot to retrieve information from Blender 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_VIEWPORT_SCREENSHOT
Even though get_viewport_screenshot 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.

FREQUENTLY ASKED QUESTIONS
What does the get_viewport_screenshot tool do?
Capture a screenshot of the 3D viewport. It is categorised as a Read tool in the Blender MCP Server, which means it retrieves data without modifying state.
How do I enforce a policy on get_viewport_screenshot?
Add a rule in your Intercept YAML policy under the tools section for get_viewport_screenshot. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Blender MCP server.
What risk level is get_viewport_screenshot?
get_viewport_screenshot is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Can I rate-limit get_viewport_screenshot?
Yes. Add a rate_limit block to the get_viewport_screenshot 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_viewport_screenshot completely?
Set action: deny in the Intercept policy for get_viewport_screenshot. 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_viewport_screenshot?
get_viewport_screenshot is provided by the Blender MCP server (ahujasid/blender-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
