Tools

Seven tools. Five are always on and need no configuration — pure-compute utilities plus an SSRF-free IP lookup. Two probe the server host and stay absent from tools/list until you opt in, fail-closed.

Tool

Description

toolkit_hash_value

Generate a cryptographic digest (sha256/sha512/sha1/md5), or constant-time-compare a value against an expected digest.

toolkit_generate_id

Mint cryptographically-random identifiers — UUIDv4, UUIDv7, or ULID — singly or in batches up to 1000.

toolkit_generate_qr

Encode text or a URL into a QR code as SVG markup, base64 PNG, or a terminal-renderable string.

toolkit_encode_value

Encode or decode a value across base64, base64url, hex, or URL percent-encoding, in either direction.

toolkit_geolocate_ip

Resolve a public IP or hostname to geographic and network metadata — country, city, coordinates, ASN, timezone.

toolkit_check_network

Gated, off by default. Read-only network diagnostics from the server host — ping, traceroute, TCP connectivity, or egress-IP detection.

toolkit_check_system

Gated, off by default. Report a facet of the server host's system state — OS, CPU, memory, load average, or network interfaces.

toolkit_hash_value

Generate a digest, or constant-time-verify a value against an expected one.

operation: generate (lowercase-hex digest) or compare (timing-safe check via timingSafeEqual)

Algorithms: sha256 (default) and sha512 for security; sha1 and md5 are exposed for checksum and file-integrity compatibility only — never for passwords or signatures

inputEncoding reads value as utf8 (default), hex, or base64, so binary blobs skip a decode round-trip

Canonical use: match
