Part of the Vimo Financial Intelligence MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call screen_stocks to retrieve information from Vimo Financial Intelligence 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 screen_stocks 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.

Add a rule in your Intercept YAML policy under the tools section for screen_stocks. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Vimo Financial Intelligence MCP server.
screen_stocks 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 screen_stocks 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 screen_stocks. 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.
screen_stocks is provided by the Vimo Financial Intelligence MCP server (cuthongthai/vimo-financial-intelligence). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
