Tools

• check_email_auth ~242 tokens
  Check a domain's live email authentication — SPF, DKIM and DMARC — and return a plain-language verdict on whether it is actually enforced. Use for questions about mail being spoofed, landing in spam, or failing delivery, and to audit a domain's anti-spoofing posture. Catches the common traps: DMARC
• check_security_headers ~189 tokens
  Fetch a URL and report which HTTP security headers it sets — HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy and Permissions-Policy — with what each one is for. Use to audit a site's header posture or verify a header change is live. Also flags weak configurations, not just missin
• check_service_status ~209 tokens
  Current reported status of major developer and consumer services (GitHub, Cloudflare, OpenAI, npm, Vercel, Discord, Reddit and others). Use when asked whether a service is down or having problems right now. Sampled from each vendor's own status page, so it reflects what the vendor admits to, and dis
• dns_lookup ~229 tokens
  Look up live DNS records for a domain (A, AAAA, MX, TXT, NS, CNAME, CAA, SOA). Use whenever the real, current DNS state matters: where a domain points, which mail servers it uses, whether it resolves at all, or to verify a DNS change actually propagated. Distinguishes a domain that does not exist (N
• find_deals ~398 tokens
  Search recently-sighted PC hardware deals aggregated from Slickdeals, r/buildapcsales and DealNews. Use when someone wants current deals on a component type or under a budget. Results are sightings recorded when first seen, NOT verified live inventory — each row carries its age so stale entries are
• ping ~81 tokens
  Health check for the pcblt server. Returns the server version and the current UTC time. Use only to confirm connectivity — it carries no other data.
• price_check ~236 tokens
  Judge whether a specific asking price for a PC part is good, by comparing it against tracked market data. Use when someone asks 'is $X a good price for Y' or wants a listing sanity-checked. Strongest for RAM, which is compared per-GB against the daily index; for other parts it falls back to matching
• ram_price_index ~204 tokens
  Current PC memory prices and their daily history: blended dollars-per-GB, the cheapest tracked kit in each DDR4/DDR5 segment, and 7- and 30-day movement. Use for any question about what RAM costs right now, whether memory prices are rising or falling, or whether to buy now or wait — RAM pricing move
• remote_job_market ~218 tokens
  Aggregate view of the remote tech job market as PC-BUILT currently tracks it: open counts by discipline, which companies are hiring most, how many postings demand US residency, and what salary data exists. Use for 'what is the remote market like for X' or to size a discipline before searching it. Th
• search_remote_jobs ~532 tokens
  Search currently-open REMOTE tech jobs aggregated from company ATS boards (Greenhouse, Ashby, Lever, Workday, iCIMS) and remote job feeds. Use when someone asks what remote roles are open in a discipline, at a company, or above a salary. Rows are sightings refreshed every ~3h, not verified live inve
• service_uptime_history ~264 tokens
  How reliable a service has actually been over time: percentage of readings operational, degraded, or in a major outage, plus a list of incident windows. Use for questions a status page cannot answer — 'how often has Vercel gone down this month', 'has OpenAI been flaky lately', 'which of these provid
• trace_redirects ~204 tokens
  Follow a URL's redirect chain hop by hop and report every stop with its status code, plus the final destination. Use to find where a shortened or tracking link actually leads before opening it, to debug redirect loops, or to check that a migration's redirects land where intended. Flags when the chai
