    Server tool list (10)

    Raw names from tools/list. Only developers need these.

    audit_wcagWebsite accessibility audit (a11y, WCAG compliance check): WCAG 2.1 level A and AA conformance of any live URL or raw HTML, tested with axe-core in a real headless browser. Returns every violation with rule id, impact, help text and affected node count. Deterministic rules; a check that cannot run returns an error, never a pass. $0.05 per call. Returns: pass (bool), violations[] with id/impact/help/help_url/nodes_affected.
    audit_seoSEO audit of a web page (on-page SEO check) for any live URL or raw HTML: title tag, meta description, H1 heading structure, canonical link, OpenGraph and social tags, JSON-LD structured data, html lang attribute. Rule-by-rule findings with severity and what is missing or malformed. $0.05 per call. Returns: pass (bool), findings[] with id/severity/detail.
    audit_securitySecurity headers check for a website: audits HTTPS, HSTS, Content- Security-Policy (CSP), X-Content-Type-Options, X-Frame-Options / clickjacking protection, Referrer-Policy and CORS from the real HTTP response of any live URL. Findings with severity for what is missing. Header posture only, not a penetration test. $0.05 per call. Returns: pass (bool), findings[] with id/severity/detail.
    audit_performancePage speed and page weight audit of a web page from one real browser load: total bytes transferred, HTTP request count and DOM node count, measured rather than estimated, with findings when the page is heavy. Page-weight signals, not Core Web Vitals. $0.05 per call. Returns: pass (bool), metrics{}, findings[] with id/severity/detail.
    audit_bundleFull website audit in one call: accessibility (WCAG 2.1 A/AA via axe-core), on-page SEO, HTTP security headers and page speed / page weight, from a single browser load of one URL. Cheaper than four separate calls; if any part cannot run, nothing is billed. $0.15 per call. Returns: pass (bool) plus wcag{}, seo{}, security{}, performance{} sub-results.
    web_fetchFetch one public URL from this node and return the response: status, headers, content type, and up to 500 KB of body text for textual content. Redirects are followed with every hop re-checked against the same private-address gate the audits use. $0.10 per call. Returns: status, final_url, headers{}, content_type, text, bytes, truncated.
    web_extractFetch one public HTML page and return its readable content as structured data: title, meta description, language, canonical URL, plain text with scripts and styles stripped, word count and outbound links. Raw parsing of the served page, no browser and no LLM in the loop. $0.10 per call. Returns: title, description, lang, text, word_count, links[], truncated.
    chain_rpcRead-only JSON-RPC against Base mainnet with upstream failover: balances, blocks, transactions, receipts, logs, eth_call and gas queries. The method allowlist is in the input schema; transaction broadcasting is deliberately not offered. A JSON-RPC error object from the chain (an eth_call revert, say) is the chain's answer and is returned as the result. $0.05 per call. Returns: network, method, result (or the chain's error object), provider.
    market_dataCurrent market data from Coinbase's public data APIs: spot price for any listed pair, full exchange-rate table for one asset, or the exchange ticker (price, bid, ask, 24h volume). Live quotes, not advice, and not a licensed market-data feed. $0.02 per call. Returns: op-dependent: amount/currency, rates{}, or price/bid/ask/volume.
    prediction_marketsLive prediction-market data from Polymarket's public Gamma API: top markets by volume, one market by slug with outcome prices, or top events. Read-only market intelligence; this node places no orders and holds no positions. $0.05 per call. Returns: markets[]/market/events[] with question, outcomes, prices, volume.
