"address validation" matching MCP tools:

• check_wallet_sanctionsA

  PG1 Sovereign Threat IntelligenceA

  PG1 Sovereign Threat Intelligence: checks a cryptocurrency wallet address against the OFAC SDN (Specially Designated Nationals) sanctions list, synced daily from US Treasury data. No payment required — this tool is always free. SIBLING DIFFERENTIATION: Use for wallet/address sanctions screening only. Do NOT use for IP/domain/hash/URL threat lookups (use get_ioc_context) or CVE data (use get_cve_details). BEHAVIOR: Returns { listed: true|false, matches, source, list_last_synced }. A listed:false result means the address is not on the OFAC SDN list as of the reported sync time — it is informational only, not legal or sanctions-compliance advice, and is never phrased as "safe" or "clean". Fails loudly (returns an error) if the sanctions data is empty or unreachable, rather than ever reporting listed:false on a data failure. VALIDATION: if the address does not match a recognised format for any supported currency (EVM, BTC/LTC/BCH/DOGE/DASH/ZEC base58 or bech32/cashaddr, TRON, Monero, Solana), returns an MCP tool error (isError: true, code invalid_address) instead of a result — it never reports listed:false for malformed input.

• update_checkoutA

  VesremontA

  Change one or more checkout fields using choices from get_checkout. Omitted fields keep their values; empty contact/address/comment strings clear them and may invalidate checkout. Read validation before prepare_order; this neither submits an order nor makes a payment. OAuth scopes: checkout:write. Changes buyer or order state.

• validate_addressA

  DIDWW MCPA

  Check whether an existing address (and its identity) satisfies a regulation or emergency requirement BEFORE creating a verification — a read-only pre-flight that changes nothing. Pass the address_id and either a requirement_id or country_iso (+ did_group_type) to resolve the requirement; requirement_type picks the rule set: "regulation" (DID registration, mirrors the panel address validation) or "emergency" (E911, mirrors the emergency address validation). Returns a valid flag plus what is missing: identity/address proof documents, supporting documents, mandatory identity fields, structural mismatches the upload flow cannot fix (identity type, country/area levels), and whether the requirement demands a one-time supporting document at verification time. The next_step field says how to proceed: create_address_verification directly when everything is in place, create_regulation_upload_link when documents (incl. the one-time document) still must be collected, update_identity for missing fields. Note: for City/Area-level requirements the city match against the actual DIDs is checked only at verification time (no DIDs are passed here).

• verify_vatA

  ENTIA Entity Verification MCPA

  Real-time EU VAT validation via VIES (27 countries). Returns {valid, name, address, vat_number, country, checked_at}. Some Member States (Spain among them) do not disclose name/address through VIES: name/address come back null with name_disclosure=withheld_by_member_state; use entity_lookup for the registered name.

• validate_actionsA

  FlowCastleA

  Dry-run validation of a proposed batch of flow-builder actions. Mutates nothing and is safe to repeat. OPTIONAL: apply_actions runs this exact validation itself and applies nothing when invalid, so calling validate_actions first is redundant — use it only to check a draft you do not intend to apply yet. Returns the same errors and warnings apply_actions would report. Note that passing validation does not mean the design is sound; structural rules live in get_design_guidelines.

• validate_emailA

  FabTally ValidA

  PAID $0.002 (x402, USDC on Base). Validate an email address: give {email} and get RFC-ish syntax validation, a LIVE MX-record (DNS) existence check, disposable/throwaway-domain detection (bundled blocklist), and a role-address flag (info@, admin@…). STATELESS and non-PII — the address is never stored and no SMTP mailbox is probed. Without payment returns the x402 challenge; pass x_payment to settle.

• wufoo_submit_entryA

  Wufoo MCP by usefulapiA

  WRITE: submits a new entry to a form, exactly as if someone filled it in — it is stored and triggers the form's notifications, webhooks and integrations. Keys are field API IDs from wufoo_get_form_fields (Field1, Field105…); fields with sub-fields (name, address, checkbox) take one key per sub-field ID. Dates must be YYYYMMDD. Field validation and form limits still apply: a rejected submission returns each field error. Limited by Wufoo to 50 submissions per user per 5 minutes. Wufoo: POST /forms/{identifier}/entries.json.

• blackwood_email_batchA

  Blackwood StateA

  Use when you need bulk email validation, email list verification or to verify email lists before a send or import. Do not use for one address (email-check is cheaper), proving a mailbox exists (no SMTP probe) or sending email. Returns JSON checking up to 20 email addresses in one call: syntax, MX records, disposable, free and role flags, SPF, DMARC and a verdict each, plus counts by verdict for 0.02 USDC per call. Typical response time 2500 ms (p95). Category: Data.

• create_wallet_accountA

  maginary-mcpA

  Create (or access) a Maginary account using a wallet signature. Sign the message ``Maginary: authenticate <address> at <timestamp>. This does not move funds.`` with EIP-191 ``personal_sign`` and pass all three values. On success, an API key is returned immediately — no email verification needed. Use this when you have a wallet but no email. The returned ``api_key`` should be passed as ``Authorization: Bearer <key>`` in the MCP client config, or via ``configure_api_key`` (stdio) / ``_meta["maginary/api_key"]`` (hosted, per-call). If the wallet already has an account, returns the existing account with a fresh API key. Args: address: EVM wallet address (0x..., 42 chars). signature: Hex-encoded EIP-191 personal_sign of the auth message. timestamp: Unix epoch seconds used in the signed message (must be within the last 5 minutes). Returns: Dict with ``address``, ``api_key`` (full key — show once), ``key_prefix``, ``created`` (bool), ``message``. On failure: ``isError`` with ``error`` = ``"validation"``, ``"signature_failed"``, or ``"rate_limited"``.

• taggun_validate_receipt_campaign_urlA

  Taggun MCP by usefulapiA

  WRITE: this scan counts against YOUR Taggun quota and plan (free for the first 30 days or 1,000 scans, then billed per scan by Taggun), even if the receipt fails validation; it is never retried automatically.

Scan a receipt at a public https URL and check it against the rules of a campaign stored on your Taggun account (dates, merchants, products, balance owing, fraud checks). Returns pass/fail with reasons. Needs the Campaign Validation feature on your Taggun plan; use taggun_list_campaigns for the ids. Same URL rules as taggun_scan_receipt_url. POST /api/validation/v1/campaign/receipt-validation/url.

• generate_sepa_xmlA

  ISO 20022 GeneratorA

  Generate SEPA XML (pain.001 or pain.008) with XSD + business validation. Included in the multi and business subscriptions (monthly quota); demo callers are limited to 2 transactions per file. Party addresses are optional and structured only: street_name, building_number, post_code, town_name, country — town_name and country are required as soon as any address field is given (SEPA banks refuse unstructured addresses from November 2026). A party accepts no other key: address_lines, a nested address object, postal_code, city and the like are refused rather than ignored. In the 2009 versions (pain.001 001.03, pain.008 001.02) a structured address passes the ISO XSD but not the German DK profile GBIC_3, which admits only Ctry and AdrLine: for a German bank, omit the address there or use the format's 2019 version (see list_supported_versions).
