Tool	Description
network_enable	Enable network request monitoring.
network_disable	Disable network request monitoring
network_get_status	Get network monitoring status.
network_monitor	Manage network request monitoring.
network_get_requests	Get captured network requests.
network_get_response_body	Get the response body for a captured request.
network_get_stats	Get network statistics.
performance_get_metrics	Get page performance metrics.
performance_coverage	Start or stop code coverage recording.
performance_take_heap_snapshot	Take a V8 heap memory snapshot
performance_trace	Start or stop a Chrome performance trace.
profiler_cpu	Start or stop CPU profiling.
profiler_heap_sampling	Start or stop heap allocation sampling.
console_get_exceptions	Get captured uncaught exceptions from the page
console_inject	Inject an in-page script, XHR, fetch, or function monitor.
console_inject_fetch_interceptor	Inject a fetch interceptor.
console_inject_xhr_interceptor	Inject an XMLHttpRequest interceptor.
console_buffers	Manage injected interceptor state.
http_request_build	Build a raw HTTP/1.x request payload.
http_plain_request	Send a raw HTTP request over plain TCP.
http2_probe	Probe an HTTP/2 endpoint.
http2_frame_build	Build a raw HTTP/2 frame.
http2_frame_parse	Decode a raw HTTP/2 frame (hex string) back into its header fields and type-specific payload (SETTINGS entries, PING opaque data, WINDOW_UPDATE increment, RST_STREAM/GOAWAY error codes, GOAWAY debug data). Inverse of http2_frame_build. Lenient: malformed payloads set decodeError but still return payloadHex.
network_http2_fingerprint	Compute an Akamai-style HTTP/2 fingerprint from one or more captured HTTP/2 frames (the client connection preface: SETTINGS + stream-0 WINDOW_UPDATE + any PRIORITY frames). Returns the canonical "<settings>|<window_update>|<priority>" string, a sha256 hash, and the structured fields (settings entries, window update increment, priorities). Ships NO hardcoded feature library — the structured fields are authoritative; the caller decides what is "bad". Pair with network_tls_fingerprint for full client identity.
grpc_frame_parse	Split a captured gRPC / gRPC-Web body into its length-prefixed messages. Each message is 1 compressed-flag byte + 4-byte big-endian length + payload. Detects gRPC-Web trailer frames (flag bit 7) and the compression flag (bit 0). Lenient: a truncated trailing message is still emitted with a warning. Each message exposes payloadHex and payloadBase64 — feed payloadBase64 directly to protobuf_decode_raw to complete the gRPC decode chain (capture body -> grpc_frame_parse -> protobuf_decode_raw).
grpc_frame_build	Encode one or more messages into a gRPC / gRPC-Web length-prefixed body. Inverse of grpc_frame_parse — for constructing test or replay bodies. Each message takes payloadHex plus optional compressed / isTrailer flags.
network_rtt_measure	Measure round-trip time to a target URL.
network_latency_stats	Measure repeated latency and compute percentile stats.
network_traceroute	Run an ICMP traceroute.
network_icmp_probe	Run an ICMP echo probe.
dns_resolve	Resolve a hostname to DNS records using the system resolver or an optional DNS server.
dns_reverse	Reverse DNS lookup — find hostnames for an IP address.
dns_probe	Run a DNS query and return structured status instead of throwing.
dns_cname_chain	Trace the full CNAME chain for a hostname.
dns_bulk_resolve	Resolve many hostnames concurrently with per-host status.
network_extract_auth	Extract authentication data from captured network requests.
network_export_har	Export captured network traffic as HAR.
network_replay_request	Replay a captured network request with optional changes.
network_intercept	Manage network interception rules.
network_tls_fingerprint	Compute TLS/HTTP fingerprints for bot detection. compute_tls/compute_http build fingerprints from user-supplied lists; parse_client_hello parses a raw ClientHello record (hex) and emits JA3 + JA4 from the real wire bytes; analyze_request links a captured requestId.
network_bot_detect_analyze	Analyze captured requests for bot-detection signals. Optionally supply a JA3/JA4 TLS fingerprint (from network_tls_fingerprint parse_client_hello) plus user-defined knownBad hash lists; matching hashes raise the bot score. Ships NO hardcoded feature library — the caller decides which hashes are bot-like.
