Claude Code: ask. ### `buy_credits` - The description's first verb is "start": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `check_domain_health` - 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: ```untrusted-server-text 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. ``` ### `extract_emails` - 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: ```untrusted-server-text Extract all email addresses found in a block of free-form text (notes, pasted documents, signatures). Optionally deduplicates and lowercases the results. ``` ### `get_started` - The name "get_started" says "get": a word for reading. - The description's first verb is "call": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `register_account` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `submit_bulk` - The name "submit_bulk" says "submit": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `verify_batch` - 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: ```untrusted-server-text 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. ``` ### `verify_email` - 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: ```untrusted-server-text Verify one email address in real time. Returns a deliverability verdict (valid / invalid / risky / unknown), the reason, detailed flags (disposable, role account, catch-all, MX, SMTP), a send/reject recommendation, and credit usage. ``` ### `verify_email_demo` - 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: ```untrusted-server-text Verify one email address with NO account or API key, so you can evaluate Verifly before registering. Rate-limited per IP (a few checks). Returns the same deliverability verdict and flags as the full API. For real volume, call register_account for a key + 100 free credits, then use verify_email. ``` ## Only reads (8) Looks things up and changes nothing. Claude Code: allow. ### `clean_email_list` - The name "clean_email_list" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text Clean a list of email addresses before an import or campaign: dedupes, removes invalid syntax, and (optionally) strips disposable and role accounts. Returns the cleaned list plus a summary of what was removed. ``` ### `get_account` - The name "get_account" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return the account profile for the current API key: email, name, company, timezone, remaining credits, total credits used, number of API keys, and plan. Costs no credits. ``` ### `get_credits` - The name "get_credits" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return the API key's remaining verification credits and recent usage (today / this month) and plan. Costs no credits. ``` ### `get_job_results` - The name "get_job_results" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Fetch the full per-address results of a completed bulk verification job by job_id (each email's verdict, recommendation, and reason) plus the valid/invalid/risky summary and credits used. The job must be 'completed' — check get_job_status first. ``` ### `get_job_status` - The name "get_job_status" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Fetch the current status and progress of a bulk verification job by its job_id (status, percent progress, processed count, and a valid/invalid/risky summary). Poll this after submit_bulk until status is 'completed', then call get_job_results. ``` ### `get_packages` - The name "get_packages" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text List the credit packages available for purchase (id, name, credit amount, price in USD, and price per 1k credits). Use the returned package id with buy_credits. ``` ### `get_usage` - The name "get_usage" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return detailed usage statistics for the account over a period (day, week, or month): total credits used, emails processed, request counts broken down by endpoint and source, a daily breakdown, and recent activity. ``` ### `list_jobs` - The name "list_jobs" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List the account's bulk verification jobs, most recent first, with their status, progress, and summary. Optionally filter by status and paginate. Use this to find past jobs and their job_ids. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `verifly`: ```json { "permissions": { "allow": [ "mcp__verifly__clean_email_list", "mcp__verifly__get_credits", "mcp__verifly__get_job_status", "mcp__verifly__get_job_results", "mcp__verifly__list_jobs", "mcp__verifly__get_usage", "mcp__verifly__get_account", "mcp__verifly__get_packages" ], "ask": [ "mcp__verifly__get_started", "mcp__verifly__verify_email_demo", "mcp__verifly__verify_email", "mcp__verifly__verify_batch", "mcp__verifly__extract_emails", "mcp__verifly__check_domain_health", "mcp__verifly__submit_bulk", "mcp__verifly__buy_credits", "mcp__verifly__register_account" ], "deny": [] } } ```
