Capabilities

Known tools 21

kv_set

Store a value durably under (namespace, key) with a TTL.

Inferred read-only

kv_get

Retrieve a value previously stored with kv_set.

Inferred read-only

kv_delete

Delete a key from your namespace.

Potential side effects

kv_list

List keys in your namespace, optionally filtered by prefix.

Inferred read-only

timer_verify_origin

One-time consent handshake before timers can deliver to an origin.

Inferred read-only

timer_schedule

Schedule a durable callback: at fire time this service POSTs your JSON payload to your URL.

Inferred read-only

timer_cancel

Cancel a pending timer by id.

Inferred read-only

timer_status

Check a timer: status (pending|delivering|delivered|failed|cancelled), attempts, last error.

Inferred read-only

name_check

Live availability check for a name across domain TLDs (registry RDAP), npm, PyPI, and GitHub usernames.

Inferred read-only

email_check

Deliverability probe for an email address without sending anything: syntax validation, live MX lookup (with A/AAAA fallback per RFC 5321), disposable-domain detection, and typo suggestions for common providers.

Potential side effects

url_check

Live URL health check: follows the full redirect chain (each hop reported), returns final status, content type, response time, TLS certificate expiry and trust, and access hints (login walls, bot blocks).

Inferred read-only

cron_next

Deterministic cron expression validator and scheduler: parses a cron expression (5 or 6 field, seconds optional) and computes the next N actual fire times, timezone-aware.

Inferred read-only

regex_test

Execute a regex against test strings and return the ACTUAL matches: match text, indices, capture groups, named groups, and optional replacement output.

Potential side effects

fixture_rows

Bulk realistic test data: generate up to 10000 rows from a field schema in one call - orders of magnitude cheaper than generating rows with tokens.

Inferred read-only

tz_convert

Deterministic timezone conversion: convert a timestamp between IANA timezones with full DST awareness.

Inferred read-only

tz_info

Timezone intelligence: for a given IANA timezone and date, returns the UTC offset, whether DST is active, the DST transition dates for that year (exact to the hour), and the timezone abbreviation.

Inferred read-only

dns_query

Full DNS record lookup for a domain: returns A, AAAA, MX, NS, TXT, CNAME, SOA, and CAA records in one call.

Inferred read-only

request_tool

Hit a capability wall?

Inferred read-only

lock_acquire

Acquire a mutual-exclusion lock so concurrent agent runs do not double-process the same work.

Inferred read-only

lock_release

Release a lock early using the token returned by lock_acquire.

Inferred read-only

counter_next

Atomically increment a named counter and return the new value.

Inferred read-only
