Get a single VAST 4.2 linear media
Single-target operation
Part of the AdButler MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call vast42_get_linear to retrieve information from AdButler 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 vast42_get_linear 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.

Get a single VAST 4.2 linear media. It is categorised as a Read tool in the AdButler MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for vast42_get_linear. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the AdButler MCP server.
vast42_get_linear 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 vast42_get_linear 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 vast42_get_linear. 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.
vast42_get_linear is provided by the AdButler MCP server (@adbutler/mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
