AI agents use seo_audit to create or modify resources in ContrastAPI. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call seo_audit repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach ContrastAPI.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

One-shot SEO audit of a domain's homepage with a 0-100 composite score + a missing_signals list of concrete fixes. Use BEFORE pitching SEO work to a prospect, when triaging a lead's marketing maturity, or as a structured pre-flight before deeper auditing tools (Lighthouse / SEMrush). 10 audit rules each worth 10 pts: title present, title length 30-60 chars (Google SERP truncation window), meta description present, meta description length 50-160, exactly one H1, canonical link, >=3 OG tags, JSON-LD present, image alt-text coverage (proportional), HTTPS. Strictly homepage-only — we do NOT crawl the site. Ethical floor: target's robots.txt is honoured — Disallow: / for ContrastAPI OR * returns 403 error.code = robots_txt_disallow and we DO NOT fetch. Cache-Control: no-store/private skips our cache write (cache_respected=false in the response). Per-target eTLD+1 throttle (60 req/min) prevents weaponising via subdomain rotation. All target-derived strings/lists are _untrusted. Free: 30/hr, Pro: 500/hr. Returns {domain, fetched_url, status_code, title_untrusted, meta_description_untrusted, canonical_url, h1_untrusted, h1_count, h2_count, h3_count, images_total, images_missing_alt, internal_link_count, external_link_count, og_tags, json_ld_present, score, missing_signals, cache_respected, summary}. Returns 502 on DNS/TCP/TLS failure; 403 robots_txt_disallow when the target opted out.. It is categorised as a Write tool in the ContrastAPI MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the ContrastAPI MCP server in PolicyLayer and add a rule for seo_audit: 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 ContrastAPI. Nothing to install.
seo_audit is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the seo_audit 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 seo_audit. 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.
seo_audit is provided by the ContrastAPI MCP server (https://api.contrastcyber.com/mcp/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
