Lie Detector Test missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

booking
get_booking_status
Check the status of an existing booking or appointment request by its reference (e.g. LDT-2026072062783). Returns the status and location. Status "request" means the request has been sent to the examiner, who will contact the person directly.
offices
find_offices
Find lie detector (polygraph) test offices near a place. Search by city, state/region, or country (United States, Canada, or United Kingdom). Returns each matching office with its address, all-inclusive prices, and a booking link.
pricing
get_pricing
Get polygraph examination pricing for a location. Returns the all-inclusive price tiers (single person, couple/two-person total, and group per-examinee) and how payment works: there is no booking fee and nothing is paid online or to LieDetectorTest.com — the client pays the examiner directly once the examiner accepts the case.
service
get_service_info
Get general information about the lie detector test service: what is offered, how booking works, how payment works, the service area, and what happens after booking. Takes no arguments.
start
start_booking
Send a free, no-obligation lie detector test appointment request for a person, directly to the examiner who covers the chosen location. Nothing is paid online and there is no booking fee: the examiner contacts the person, agrees the date, payment and cancellation terms with them, and the person pays the examiner directly. Only use this when the person has asked you to send the request with these details. Returns a booking reference, the office and a page link where the person can see their examiner (and optionally complete a confidential pre-examination questionnaire). Do not put the person's contact details in any URL.

Lie Detector Test — questions

Answers built from our own checks of this server.

What can Lie Detector Test do?
It exposes 5 tools, read directly from the server on our last check. Among them: find_offices, get_booking_status, get_pricing, get_service_info, start_booking. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Lie Detector Test working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 478 ms. The bar chart above shows every period we have measured.
How do I connect Lie Detector Test?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Lie Detector Test need an API key?
No. Lie Detector Test completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Lie Detector Test?
It answers our handshake in 478 ms on average, which is faster than 26% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
