✓ Watched since 2026-06-03 — behavioral baseline locked. We re-check this server's tool surface on a schedule; if it adds, removes, or silently rewrites a tool (rug-pull), we record it.

What it offers — 12 tools · Developer Tools

cross_lens_verify

A2 — the cross-lens join. Fuse TunnelMind's two lenses (Scry attacker intelligence + Sigil supply graph) into ONE verdict on a single node key. This i

sigil_verify_supply_path

The core pre-bid check. Verify the trustworthiness of one programmatic ad supply path and get back a composite trust verdict plus a signed proof token

sigil_verify_ads_txt

Check whether an exchange/SSP is authorized to sell a publisher's inventory, per the publisher's ads.txt file. Fast cached lookup against Sigil's dail

sigil_verify_ip_type

Classify an IPv4 address as datacenter, residential, mobile, or unknown. Detects datacenter traffic posing as real user devices. Stateless — the IP is

sigil_verify_app_bundle

Verify that a mobile/CTV app bundle ID actually exists in its app store and, optionally, that the listed developer matches. Detects bundle-ID spoofing

sigil_verify_supply_chain

Verify a full OpenRTB SupplyChain (schain) object — every node, end to end. Per node Sigil checks the seller against the exchange sellers.json and the

traverse_supply_chain

Walk the supply graph for a publisher domain and get back the ITEMIZED sell paths — distinct from sigil_verify_supply_chain (which verifies a schain y

sigil_score_entity

Get the pre-computed trust score for one supply-chain entity (a publisher or an SSP). Scores are recomputed daily from ads.txt health, supply-chain di

sigil_score_batch

Pre-computed trust scores for up to 200 entities in one call — built for an agent evaluating many supply sources during campaign setup. Use this tool

sigil_atap_register_ait

Register an ATAP v0.1 Agent Identity Token for a media-buying agent. Sigil validates the capabilities + constraints against the `sigil:media_buyer:v1`

sigil_atap_witness

Witness one agent-reported bid or budget event into an AIT's hash-chained attestation log. Sigil validates the payload (rejecting any PII), classifies

sigil_generate_receipt

Generate the ATAP v0.1 compliance Receipt for an AIT — the portable, signed artifact a media buyer hands its principal. The receipt grades every event

Observed behavior

No proxied traffic observed for this host yet. Connect it at /connect and its grade gains a measured Reliability score + per-tool behavioral evidence — the half a static scan can't produce.

Findings

No blocking issues found in the static + spec checks.

Agents: check this before connecting

Add the wmcp.sh trust oracle as an MCP server and call grade_mcp_server / check_mcp_drift in your agent's pre-connection gate:

How this grade is computed. An open, independent rubric — Spec conformance (20%), Security mapped to the OWASP MCP Top 10 (30%), Reliability (20%), Tool hygiene (15%), Transparency (15%) — run by connecting to the server and inspecting its real MCP surface. The grade is free and identical whether or not the operator pays. v1 uses static + spec signals from a single connection; continuous uptime, real latency, and annotation-truthing (declared readOnly vs observed behavior) layer on via the wmcp.sh proxy.
