PCBLT — Live Checks
com.pcblt/pcblt · 0.4.0
Live DNS, email-auth and redirect checks, HTTP security headers, uptime history, PC hardware prices.
Nobody here has read this server's code, because it publishes none. The description above is the maker's own, from the registry. A connection test shows whether it answers and what tools it says it has; it never calls a tool, so it cannot show what one does with your data.
Where it sits in the directory's order
What can be seen from outside, weighed as the directory publishes.
Observable signals: 45 of 100 points (at most 60 here)
| Input | Points | What was seen |
|---|---|---|
| Source published | held at 0 | No entry here publishes source: that is what puts it in this directory. |
| Licence stated | held at 0 | With no files, there is nothing for a licence to be stated in or held against. |
| Advisory state | held at 0 | Advisory databases index packages, and these entries publish none, so there is nothing to look up. |
| Auth declared | 0 of 15 | The registry entry declares no key. That is what it declares, not a finding that it has no protection. |
| Latest connection test reached it | 20 of 20 |

Connection test
The MCP handshake, then a request for the tool list, with no key and no data of yours. Run nightly, and by anyone, at most once every ten minutes per server.
It completed the handshake and listed 12 tools.

The tools it lists (12, as of 3 days ago)
The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.
pingHealth check for the pcblt server. Returns the server version and the current UTC time. Use only to confirm connectivity — it carries no other data.
dns_lookupLook 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 (NXDOMAIN) from one with no record of that type.
check_email_authCheck 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 stuck at p=none (monitoring only, nothing blocked), pct below 100, SPF +all, and duplicate SPF records. Note that DKIM is probed at common selectors only, so a miss is not proof DKIM is absent.
trace_redirectsFollow 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 chain ends on a different host than it started on.
check_security_headersFetch 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 missing headers: short HSTS max-age, no includeSubDomains, and CSP containing unsafe-inline or unsafe-eval.
How this entry becomes a listing
For the maker. The catalogue lists what it can read, and this server publishes nothing to read yet. There are two routes, and only the first is open today.
Publish the source Open today
- Put the server's source in a public repository on github.com, with a licence.
- Keep a server.json in that repository naming this server,
com.pcblt/pcblt, and declare the repository in it:"repository": { "url": "https://github.com/owner/repo", "source": "github" }, adding"subfolder"when the server lives in a folder. - Publish that version to the official MCP registry.
- The nightly registry sweep records the declaration. This page stays, dated, and says the source is declared but not yet read.
- The catalogue reads declared repositories at a pinned commit, in batches run by hand, and lists the servers that meet the batch's rules (among them a server.json at that commit naming the server, an https endpoint and a licence). When it lists this server, this page links to the listing. There is no schedule, so no date can be promised.
