Available tools 10

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

guidance

check_guidance_status

Use before answering or acting when current official GOV.UK employment guidance materially matters. Returns current preserved verification status, freshness and provenance for one or all monitored sources. Free.

get_guidance_changes

Use when the task asks whether monitored official UK employment guidance changed, what changed, or whether earlier retained guidance differs from the latest preserved state. Free.

list_guidance_sources

Use when an agent first needs to see which UK employment-guidance classes G05 can verify. Lists only the monitored GOV.UK source set; do not use as legal advice or for unrelated GOV.UK content. Free.

search_guidance_sources

Use when ordinary employment/payroll language must be mapped to a monitored G05 source before checking current official guidance. Searches only the bounded GOV.UK source set. Free.

aios

aios_status

Return public AIOS discovery state. Free; no product result.

capabilities

list_capabilities

List public AIOS capabilities and availability. Free.

capability

get_capability

Describe one stable public AIOS capability ID. Free.

preflight

preflight_request

Check bounded capability readiness without returning the substantive result. Free.

pricing

list_pricing

Return Public Discovery free state and intended introductory paid pricing. Free.

verification

get_verification_evidence

Use when an agent needs evidence for a consequential answer: authoritative source identity, verification time, provenance and a bounded excerpt from a monitored GOV.UK employment source. Free.

AIOS Public Discovery — questions

Answers built from our own checks of this server.

What can AIOS Public Discovery do?

It exposes 10 tools, read directly from the server on our last check. Among them: aios_status, check_guidance_status, get_capability, get_guidance_changes, get_verification_evidence, list_capabilities and 4 more. 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 AIOS Public Discovery 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 180 ms. The bar chart above shows every period we have measured.

How do I connect AIOS Public Discovery?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does AIOS Public Discovery need an API key?

No. AIOS Public Discovery completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is AIOS Public Discovery?

It answers our handshake in 180 ms on average, which is faster than 67% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
