Changes things 9Creates or changes something that can be changed back.Claude Code: ask

buy_creditsStart a purchase of a credit package and return a way to pay.No findings
Why it is in this group
- The description's first verb is "start": a word for a change.
Description, as the server wrote it
Start a purchase of a credit package and return a way to pay. This does NOT complete a payment by itself — it returns a payment link / address: • method 'stripe' → returns a checkout_url. Paying by card requires a HUMAN to open that link and enter card details; an agent cannot finish a card payment on its own. • method 'crypto' → returns a Plisio invoice with a checkout_url AND, when you pass a `currency` (BTC, ETH, LTC, USDT, USDC), a RAW wallet `address` + `amount`. An autonomous agent CAN pay this from a crypto wallet with no browser/human, then credits are added automatically once the payment confirms. Prefer crypto for fully autonomous top-ups. Get a package id from get_packages first.
Annotations the server declares
- title: Buy credits (returns a payment link or crypto invoice)
- readOnlyHint: false
- destructiveHint: false
- openWorldHint: true
check_domain_healthCheck the DNS and deliverability health of an email domain: MX records, SPF, DMARC, and an overall health score.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Check the DNS and deliverability health of an email domain: MX records, SPF, DMARC, and an overall health score. Useful for diagnosing why a domain bounces or for validating a sending domain.
Annotations the server declares
- title: Check email-domain health (MX / SPF / DMARC)
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: true
extract_emailsExtract all email addresses found in a block of free-form text (notes, pasted documents, signatures).No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Extract all email addresses found in a block of free-form text (notes, pasted documents, signatures). Optionally deduplicates and lowercases the results.
Annotations the server declares
- title: Extract email addresses from text
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: false

  Matched text
  annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The name "get_started" says "get": a word for reading.
  What this check looks for
Description, as the server wrote it
Call this FIRST if you have no Verifly API key. Returns how Verifly works and how to get access with no human: pay-as-you-go email verification API, 100 free credits on self-registration, no monthly fee. No API key required to call this tool.

- title: How to start using Verifly (no key needed)
- readOnlyHint: true
- destructiveHint: false

register_accountProgrammatically create a brand-new Verifly account — this is how an agent self-onboards with no human in the loop.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Programmatically create a brand-new Verifly account — this is how an agent self-onboards with no human in the loop. Requires only an email and a password (min 8 chars; disposable email domains are rejected). The new account starts with free credits. The response includes the new account id/email and a freshly generated `api_key.key` that is shown ONCE — capture and store it immediately, it cannot be retrieved again. Subsequent tool calls can then use that key as the bearer token.
Annotations the server declares
- title: Self-register a new Verifly account + API key
- readOnlyHint: false
- destructiveHint: false
- openWorldHint: false
submit_bulkSubmit a list of email addresses as an asynchronous bulk verification job — the right tool for large lists.No findings
Why it is in this group
- The name "submit_bulk" says "submit": a word for a change.
Description, as the server wrote it
Submit a list of email addresses as an asynchronous bulk verification job — the right tool for large lists. Returns immediately with a job_id, status, and the check_status_url / results_url to poll. Small lists may complete inline (status 'completed'); larger ones return status 'pending' — poll get_job_status until it is 'completed', then call get_job_results. Optionally register a webhook_url (public HTTPS) to be notified when the job finishes.

- readOnlyHint: false
- destructiveHint: false
- openWorldHint: true

- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Synchronously verify a list of email addresses (best for up to a few hundred). Returns a per-address verdict for each email. For very large lists use the bulk async endpoint instead.
Annotations the server declares
- title: Verify a batch of email addresses
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: true
verify_emailVerify one email address in real time.No findings
Why it is in this group

Description, as the server wrote it

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
