Raise conversion on a site you manage. No API key, no human to wake — you prove the domain.
Cromanion is a remote MCP server published at cromanion.com. It has been probed 8 times since 9/12/2026. It answered in 8 of them (100.0%), a near-uninterrupted record. Median response time is 342 ms, placing it among the faster endpoints. It exposes a broad tool surface of 26 tools. On the protocol side it speaks the 2026-07-28 stateless spec.
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
cromanion_pending — Description is vague about when to use it, only stating it shows 'what is waiting for a decision'.cromanion_add_goal — Numerous optional parameters (e.g., 'type', 'value', 'label') lack clear definitions of required vs. optional fields.cromanion_set_holdout — Parameter 'siteId' is optional but not explained when it is required.Risk: low
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
cromanion_open_claimStart here, and you need nothing to do it — no API key, no human. This call takes no credential and creates NOTHING: no account, no key, no charge. It returns a challenge to publish on the site you manage (a file, a meta tag or a DNS record — whichever your hosting lets you write) and the secret you will authenticate with once the proof is read. That proof is the whole trust model: we cannot take your word for an email address, but we can check what you control. Store the secret; it is shown once. Refuses if the address already has an account, because controlling a site does not prove controlling a mailbox.
emailstringrequiredsiteUrlstringrequiredagentstringcromanion_verify_claimRedeem a claim once you have published one of its three proofs (a /.well-known file, a <meta> tag, or a DNS TXT record). On success it creates the account and the site and returns the tracking snippet to install. Idempotent — safe to retry. Requires the claim secret as a bearer token.
cromanion_site_statusCheck the site you provisioned: whether the tag is actually live (a beacon received from your own domain, not merely a snippet handed to you), how the crawl is going, and the plan. Poll this after installing the snippet. Requires the claim secret as a bearer token.
siteIdstringcromanion_install_checkWhy the tag is not firing. cromanion_site_status tells you `verified: false`; this tells you WHY — fetching your human's own pages and reporting, per page, whether the tag is there and what is stopping it. It finds the four failures a boolean cannot: the tag missing from some pages but not others, a Content-Security-Policy blocking the script, a consent manager holding it, and beacons arriving from a host the site was not claimed under. Each comes back with the fix. Rate-limited to one check every two minutes, because it fetches ten pages from your human's server.
siteIdstringcromanion_upgrade_linkGet a Stripe Checkout link for a paid plan (pro or growth). Returns a URL and nothing else — YOU do not pay and cannot: give the link to your human, who enters their own card. The site works on the free plan meanwhile. Requires the claim secret as a bearer token.
siteIdstringplanstringrequiredcromanion_errorsEvery refusal this server can return, and what to do about each. Needs no credential — you can read it before you have one, or after a refusal has told you the one you had is gone. The field to branch on is `retry`: `later` means a cooldown or a transient, `fix_request` means change something and resend, `needs_human` means nothing you send will help until a person acts. Read it once and stop guessing whether a 409 is worth retrying.
cromanion_grantsList what your human has allowed this agent to do, and what they have not. Read this before assuming a capability — the alternative is discovering your permissions by failing in front of them. You cannot change these yourself; only your human can, in their console.
cromanion_pendingEverything on this site that is waiting for a decision: page rewrites the agent wants to make, rules it distilled from real sessions, conversions it spotted but has never counted, and pages your traffic found that the crawl missed. This is the client's actual job in the console, in one call. Rule on an item with cromanion_decide.
siteIdstringcromanion_configEverything IN FORCE on this site: the conversions that count, the facts you may state and the ones forbidden, which surfaces are enabled, the brand, and every distilled rule WITH its status. cromanion_pending shows what is waiting for a decision; this shows what was already decided — including by you. Read it before writing anything, because most writes here REPLACE rather than add.
siteIdstringcromanion_decideRule on one thing from cromanion_pending: pass its `kind` and `id` back unchanged with a decision. `approve` / `reject` for everything; `pause` additionally for a playbook rule. Approving a GOAL is different in kind from the rest — it changes what every impact figure for this site means, permanently. You cannot edit rule text here, only rule on it.
siteIdstringkindstringrequiredidstringdecisionstringrequiredallbooleancromanion_set_playbookReword a distilled rule, or ask for a fresh distillation. Rules are what the agent learned from real sessions; cromanion_decide approves or pauses them, and this changes what they SAY. Send a ruleId with condition and/or recommendedAction to reword one — ids come from cromanion_config, which also shows rules you have already approved or paused. Send redistill: true instead to distil new rules from recent sessions; they arrive as `proposed` for you to rule on. Rate-limited to one distillation an hour. Needs the decisions permission.
siteIdstringruleIdstringconditionstringrecommendedActionstringredistillbooleancromanion_ask_humanAsk your human for something only they can do, in a place they will actually see it. Every other refusal here ends with YOU reading it — a permission they did not grant, a payment you cannot make, a mode you may not set — and from their side you simply went quiet. This puts one request on their notifications screen, attributed to you. Nothing replies here: they act in their console, and you find out by reading cromanion_grants or cromanion_config again. One request an hour, and a second from you replaces the first rather than stacking.

**AI-readiness audit for any public website** — ecommerce, content, SaaS, docs, marketing sites. Built for the era where AI assistants (ChatGPT, Perplexity, Claude, Google AI Overviews) decide who gets cited. When a shopper asks ChatGPT *"what's the most comfortable lightweight summer shoe?"* — does **Crocs** show up? When someone asks Perplexity *"best running shoes for marathon training"* — is **Academy Sports** in the answer? When a buyer asks Claude *"where should I buy an engagement ring online?"* — does **Signet** appear with a citation? The answer depends on whether your site has the metadata, structured data, and AI-crawler signals that LLM-powered search engines actually parse. Most sites were built for human SEO (Google blue links). They've never been audited for **AI citation readiness**. Multipliers Site Auditor changes that. Point it at any public URL and in ~20 seconds you get a **comprehensive, evidence-backed report**: - A **0–100 AI-readiness score** with a transpa

Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
The two probe legs separately: modern server/discover and legacy initialize.
