TunnelMind MCP server

• Registry nameai.tunnelmind/dataverified in the MCP registry

The registry name sits under tunnelmind.ai. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-11-04 the server answered initialize and tools/list without a sign-in. First answer in 210 ms.

• Whether its tools do the product's job has not been judged yet.
• Checked on 1 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• sigil_verify_ads_txt

  Confirms whether an SSP/exchange is authorized to sell a publisher's inventory according to that publisher's ads.txt. This is a cache lookup against ads.txt files crawled daily across the top 10,000 publisher domains — it does NOT fetch…

• sigil_verify_ads_txt_batch

  Runs up to 100 ads.txt verifications in a single call — the endpoint an ad-buying agent uses for pre-bid checks across a whole campaign's supply. Each item is the same shape as `sigil_verify_ads_txt`. Per-item validation failures are…

• traction

  Live traction numbers computed from sources the Worker owns: the hash-chained D1 audit log (7-day call volume, distinct identified callers, top operations), the stored-receipt table, and Stripe (succeeded charges → paying customers, gross…

• tollbooth_stats

  The public read over the Conduct Log Commons: which agents knocked on attested tollbooth sites in the last 7 days, what they did when offered paid access, and what they would have paid. First-party monitors and credential-scanning recon…

• tollbooth_export

  Free bulk read of the commons — the raw record is never paywalled. Every row is a tollbooth document exactly as its site signed it (Ed25519 over RFC 8785 JCS, key = the row's own `site`), wrapped in a `_commons` envelope naming the tier…

• tollbooth_sites

  Membership of the commons: every signing key that has reported, the domain that vouched for it (by serving the key in its /.well-known/tollbooth-site.json), and when it was last re-checked. Attested only by default; tier=all adds…

• snapshot_manifest

  P4 corpus replication, the OPA "push data into the PDP" pattern. A daily snapshot of the domain corpus (domain, score, category, fingerprinting, entity) is published as deterministic JSONL with a manifest carrying row_count, sha256 over…

• snapshot_data

  The exact bytes the manifest's sha256 commits to. Content-Type `application/x-ndjson`; rows ordered by domain. Verify: `sha256(body) == manifest.sha256`.

• snapshot_diff

  JSONL diff vs the previous snapshot — apply +/~/- lines instead of re-pulling the corpus.

• status_history

  One sample per 20-minute monitor sweep. `uptime_pct` is the share of sweeps in which every fail point was green (the strictest read); `per_monitor` lists only monitors that failed at least once in the window. History begins at feature…

• get_self_view

  P83 Gate 1. The caller is the subject: every fact here comes from the TLS handshake and headers the caller has already sent, so there is no render, no browser, and nothing to authorize. Three surfaces: - `client` — user-agent, HTTP…

• agent_registries_lookup

  P75 registry aggregation: the cross-lens join applied to agent identity. Incumbent providers each consult only their own registry; this endpoint checks every registry TunnelMind can reach and labels each answer with an explicit state, so…

• verify_agent

  Reconciles a claimed bot User-Agent against the operator's OWN published IP-range feed (Googlebot, GPTBot, OAI-SearchBot, ChatGPT-User, PerplexityBot, Perplexity-User, Bingbot). A User-Agent is trivial to forge; membership in the…

• verify_agent_signature

  Neutral third-party Web Bot Auth verification. An origin — or the PDP deciding for it — received a request from a claimed agent carrying the Web Bot Auth headers (Signature, Signature-Input, Signature-Agent). Relay those headers here…

• create_subscription

  Subscribe to a node (ip, domain, asn, or entity slug). On a recurring sweep (~20 min) TunnelMind re-runs the fused `POST /v1/verify` verdict and, when the *material* result changes — the verdict label flips, the trust score crosses a…

• list_subscriptions

  Returns the caller's active and inactive subscriptions (signing_key redacted). Requires an API key.

• get_subscription

  Read one of your subscriptions (signing_key redacted).

• delete_subscription

  Cancel a subscription.

• receipt_log_sth

  P72 RFC 6962 transparency log over the unified receipt ledger (ADR-010). The STH commits to the entire log: `tree_size`, `root_hash` (`0x` + SHA-256), `timestamp`, and an Ed25519 signature (with `key_id` and embedded public key) over the…

• receipt_log_inclusion_proof

  Proves a specific receipt (by unified `receipt_id`, lens alias, or raw `leaf_index`) is included in the tree at `tree_size` (default: the latest STH's). Returns `leaf_hash`, the `audit_path`, the recomputed `root_hash`, and the matching…

• receipt_log_consistency_proof

  Proves the log at size `second` is an append-only extension of the log at size `first` — history was never rewritten. Returns both roots and the proof path. Verify offline with `scripts/verify-log.mjs consistency <proof.json>`.

• receipt_lookup

  P72 unified receipt ledger (ADR-010): every receipt-issuing surface (cross-lens verify, tracker verify, verdict, profile, explain, GhostRoute, Sigil/ATAP, compliance export) records the exact signed document it returned, keyed by one ID…

• attributes_lookup

  P73 fast attributes endpoint (PIP-PLAN P3): a full `POST /v1/verify` resolve fans out across four lenses (~2s) — fine for preflight, fatal inside a per-request authorization loop. This endpoint serves the last-known signed bundle from a…

• tracker_verify

  The Tracker lens-owned verify surface: a per-node verdict over the normalized DDG Tracker Radar / IAB TCF / Disconnect.me corpus, with an optional signed TunnelMind Receipt v1.0. This is the single-lens ground truth the fused `POST…

• sigil_verify_domain

  Confirms a publisher controls a domain by checking for a DNS TXT record the owner publishes under `_tunnelmind.{domain}`. A DNS record can only be set by whoever controls the zone, so its presence proves control — a stronger signal than…

• sigil_verify_ip_type

  Classifies an IPv4 or IPv6 address by network type — the high-value ad-fraud signal being datacenter traffic posing as residential or living-room (CTV) devices. IP→ASN resolution uses Team Cymru's public service; the ASN is then…

• sigil_verify_adscert

  Reports whether a domain publishes ads.cert (IAB Tech Lab Authenticated Connections) DNS records — a readiness signal showing the domain supports cryptographically authenticated ad-tech connections. This is not signature verification…

• sigil_verify_app_bundle

  Verifies that a mobile or CTV app bundle ID actually exists in the relevant app store — used to detect bundle spoofing in bid requests. Platform support (v1): - `ios`: verified live via Apple's iTunes Lookup API. - `android`: verified…

• cross_lens_verify

  A2 — the cross-lens join. TunnelMind owns multiple halves of the open-web graph: Scry sees who is on every IP (attacker intelligence, actor class, Augur threat-intel overlap); Sigil sees the supply graph (publishers, SSPs, DSPs, ads.txt +…

• cross_lens_lookup

  Returns all three lens views for a single node key without computing a fused verdict. Use this when you want raw transparency — the Tracker catalog presence, Scry attacker observations, and Sigil supply-graph position — and intend to make…

• verdict_lookup

  The reconciliation layer in one call. Where `cross_lens_verify` answers "what is this network destination," `verdict_lookup` answers a different, sharper question about a key-addressed ACTOR: **does what this key claims about itself match…

• preflight_should_i_act

  The single call an agent makes before transacting with a destination on the open web. Composes the cross-lens verdict with a bounded Tracker-presence bonus, maps the adjusted trust score to a tri-state decision (`allow` / `caution` /…

• explain_verdict

  Call this when you need to ACT ON a verdict and prove why. It returns the exact verdict `/v1/verify/{node}` computes (same fusion, same weights) PLUS a traced evidence chain: every claim is attributed to where it came from — the attested…

• profile_entity

  At least one of `ip`, `domain` or `entity` is required. Call this before routing traffic, bidding on inventory, or trusting a counterparty. It fuses ALL THREE TunnelMind lenses for one subject — Scry (attacker intelligence + threat feeds…

• signal_tracker_density

  Observed component counts first, a labelled derived roll-up second. The components — `data_categories`, supply-surface counts (ssp + publisher + dsp + owns_seat + buys_through), and corroborating `sources` — are facts…

• signal_dark_pool_risk

  Reconciles every sell path a publisher declares (`sells_through`) against each SSP's own sellers.json (`exchange_seat`) and keeps three classes strictly separate: `corroborated` (seat present), `contradicted` (SSP crawled but seller_id…

• signal_halo_score

  Scores an entity by the trust character of its neighbours — the SSPs its publishers sell through and the DSPs it buys through. Reports neighbour counts, mean/min neighbour trust, and how many neighbours are adversary-classified (P46)…

• signal_team_signal

  Surfaces other entities that operate as a coordinated team with this one: they share a NARROWLY-held direct seller account (2–8 entities — network house accounts shared by hundreds are separated into `house_accounts_excluded`, not…
