AI agents call solve_captcha to retrieve information from Screenshotsmcp 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 solve_captcha 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.

Automatically solve CAPTCHAs on the current page using CapSolver AI. Supports Cloudflare Turnstile, reCAPTCHA v2/v3, and hCaptcha. Detects the CAPTCHA type and sitekey automatically, sends it to CapSolver for solving, injects the token, and optionally submits the form. Use this when a CAPTCHA blocks form submission during browser automation.. It is categorised as a Read tool in the Screenshotsmcp MCP Server, which means it retrieves data without modifying state.
Register the Screenshots MCP server in PolicyLayer and add a rule for solve_captcha: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Screenshotsmcp. Nothing to install.
solve_captcha 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 solve_captcha rule in your PolicyLayer 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 PolicyLayer policy for solve_captcha. 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.
solve_captcha is provided by the Screenshots MCP server (relievedattention992-smithery/screenshotsmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
