John Jost — published profile bronze

thejspro.com

“John Jost's published professional profile, served from the same content modules as thejspro.com. Read-only: nothing here changes anything, contacts him, books time or sends a message. This server has been reviewed adversarially by independent AI evaluators, twice: once as first built, and again after it was rebuilt from scratch against the site's own data. Each round put hard questions to it, about seniority, product ownership, backend and full-stack work, typography, greenfield delivery and the accuracy of its own claims. Every defect found was fixed; one finding was itself incorrect and was defended against; and one found that the server's own copy overstated public verifiability, which is why that copy now says exactly what can and cannot be checked. The review transcripts are not published. What you can check is the behaviour: put the same hard questions to this server yourself, and compare its answers against thejspro.com and the corroboration links in get_attestations.

Verified by agenttru.st

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate

Issued by Google Trust Services domain-validated

Valid until 4 Feb 2027 as of our check on 8 Nov 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

Control of the hostname was checked; nothing about who operates it.

Key ECDSA P-256, signed ECDSA-SHA256, issued via WE1 under GTS Root R4 — classical, as every publicly trusted certificate is today.

Names on this certificate (3)

thejspro.com, mcp.thejspro.com, *.mcp.thejspro.com.

Connection

TLS 1.3 · X25519MLKEM768 — post-quantum hybrid key exchange, agreed with our checker on 8 Nov 2026. The agent is served from mcp.thejspro.com, so that server's operator chose this. What this means

DANE / TLSA

Not verified (TLSA query returned RCodeNameError)

Discovery

Well-known document

AI use policy

Search: yesAI input: yesAI training: nouse: reference

What this site's robots.txt says about how AI may use its content. Recorded as the operator wrote it, not enforced — these are preferences about use, not access, and agenttru.st only reads the agent's own discovery documents.

AI-facing documents

Publishes /llms.txt — “thejspro.com” a curated map of the site's content for language models

Fetched from this host during verification. Neither document is how this agent was discovered.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of thejspro.com controls every word below.

This card declares no skills. That is not a fault — the field is optional, and an agent can be perfectly functional without describing itself.

What kind of listing

• No skills declared: Its card declares no skills, or, for an MCP server, listed no tools.

Checked by agenttru.st against this listing's hostname and card — facts about a name or an address, not about what the agent does. How kinds are decided.

Technical agent card
