"How to Search for Legitimate Email Addresses" matching MCP tools:
- Search npm or PyPI to estimate how crowded a package category is before you claim that a market is empty, niche, or competitive. Use this when you have a category or search phrase such as 'edge orm' and want live result counts plus representative matches. Do not use it to compare exact known package names or to infer adoption from downloads; it reflects search results, not market share. Registry responses are cached for 5 minutes.Connector
- Fetch full details of a single participant from a sweepstakes by token, email, or phone. At least one search parameter is required. Use fetch_sweepstakes first to get the sweepstakes_token. For listing participants, use fetch_participants instead. NEVER fabricate, invent, or hallucinate participant data under any circumstance. If no result is returned by the API, report exactly that — do not guess names, emails, or counts. Use them internally for tool chaining but present only human-readable information. # get_participant ## When to use Fetch full details of a single participant from a sweepstakes by token, email, or phone. At least one search parameter is required. Use fetch_sweepstakes first to get the sweepstakes_token. For listing participants, use fetch_participants instead. NEVER fabricate, invent, or hallucinate participant data under any circumstance. If no result is returned by the API, report exactly that — do not guess names, emails, or counts. Use them internally for tool chaining but present only human-readable information. ## Pre-calls required 1. fetch_sweepstakes if the user gave you a sweepstakes name instead of a token ## Parameters to validate before calling - sweepstakes_token (string, required) — The sweepstakes token (UUID format) - participant_token (string, optional) — The participant token (UUID format) - use this OR email OR phone - email (string, optional) — Participant email address - use this OR participant_token OR phone - phone (string, optional) — Participant phone number (10 digits) - use this OR participant_token OR emailConnector
- Register a new agent account and get an API key. No authentication needed. The returned API key grants read+write access to all BorealHost API endpoints. Store it securely — it cannot be retrieved again. The key is automatically activated for this session — all subsequent tool calls will use it. No extra configuration needed. If no email is provided, a synthetic agent identity is created (agent-{uuid}@api.borealhost.ai). If an email is provided, it links to an existing or new human account. Args: name: Human-readable name for this API key (default: "Agent Key") email: Optional email to link to a human account Returns: {"api_key": "bh_...", "key_id": "uuid", "prefix": "bh_...", "scopes": ["read", "write"], "account_id": "uuid", "message": "Store this API key securely..."} Errors: RATE_LIMITED: Max 5 registrations per IP per hour VALIDATION_ERROR: Invalid email formatConnector
- Get a human's FULL profile including contact info (email, Telegram, Signal), crypto wallets, fiat payment methods (PayPal, Venmo, etc.), and social links. Requires agent_key from register_agent. Rate limited: PRO = 50/day. Alternative: $0.05 via x402. Use this before create_job_offer to see how to pay the human. The human_id comes from search_humans results.Connector
- Transfer multiple ENS names in a single transaction via Multicall3 — bulk send. Much cheaper and faster than transferring names one at a time. Supports up to 20 names per batch. Automatically detects whether each name is wrapped (NameWrapper/ERC-1155) or unwrapped (BaseRegistrar/ERC-721) and builds the correct transfer call for each. All names can go to the same recipient or to different recipients — specify a toAddress per name. Requirements: - The fromAddress must currently own ALL names in the batch - All addresses must be valid Ethereum addresses - Names must be registered (not expired) WARNING: This transfers FULL ownership of every name. Recipients gain complete control. Resolver records (avatar, addresses, etc.) are NOT affected by transfer — they stay on each name. After transfer, consider using bulk_set_records to update ETH address records on the transferred names.Connector

- Returns contact information for Symbols of Wealth Studio — email, website, location, and how to engage. Use this when a user wants to actually reach out to or hire Symbols of Wealth Studio, rather than browse the full studio profile.Connector
- Request a free Nefesh API key. No existing API key needed for this call. IMPORTANT: You MUST ask the user for their real email address before calling this tool. Do NOT invent, guess, or generate an email address. The user will receive a verification link they must click to activate the key. Without clicking that link, no API key will be issued. Disposable or temporary email services are blocked. Example prompt to the user: "What is your email address? You will receive a verification link to activate your free API key." Flow: call this with the user's real email, then poll check_api_key_status every 10 seconds until status is 'ready'. Free tier: 1,000 calls/month, all signal types, 10 req/min. No credit card.Connector
- General search tool. This is your FIRST entry point to look up for possible tokens, entities, and addresses related to a query. Do NOT use this tool for prediction markets. For Polymarket names, topics, event slugs, or URLs, use `prediction_market_lookup` instead. Nansen MCP does not support NFTs, however check using this tool if the query relates to a token. Regular tokens and NFTs can have the same name. This tool allows you to: - Check if a (fungible) token exists by name, symbol, or contract address - Search information about a token - Current price in USD - Trading volume - Contract address and chain information - Market cap and supply data when available - Search information about an entity - Find Nansen labels of an address (EOA) or resolve a domain (.eth, .sol)Connector
- Resend the email verification link for an existing Unphurl account. Use this when a user signed up but their verification link expired (links are valid for 24 hours) and they need a new one. The user's API key won't work until their email is verified. For security, the response is always the same regardless of whether the email exists, is already verified, or was rate limited. This prevents account enumeration. Rate limited to 3 requests per email per hour. This tool does not require an API key.Connector
- Create a Disco account and get an API key. Provide an email address to start the signup flow. If email verification is required, returns {"status": "verification_required"} — the user will receive a 6-digit code by email, then call discovery_signup_verify to complete signup and receive the API key. The free tier (10 credits/month, unlimited public runs) is active immediately. No authentication required. Returns 409 if the email is already registered. Args: email: Email address for the new account. name: Display name (optional — defaults to email local part).Connector

- List top sending sources (ESPs, ISPs, mail services) for a domain, grouped by source type. Filters: "known" (legitimate ESPs like Google, Mailgun), "unknown" (unrecognized senders), "forward" (forwarding services). Empty = all types. Returns top 20 per type with message volume, SPF/DKIM/DMARC pass/fail counts. Use this to investigate WHERE email is being sent from — especially when unknown sources appear or compliance is low. To drill down into a specific source (by IP, ISP, hostname, or reporter), use get_domain_source_details.Connector
- Get a new API key for an existing Disco account. Sends a 6-digit verification code to the email address. Call discovery_login_verify with the code to receive a new API key. Use this when you need an API key for an account that already exists (e.g. the key was lost or this is a new agent session). Returns 404 if no account exists with this email — use discovery_signup instead. Args: email: Email address of the existing account.Connector
- Preview today's content from 3 channels. No signup, no arguments required. Call this first to see what your human would receive. If you like it, call start_subscription to activate. Args: source: Optional. How you found us (e.g. "mcpregistry", "relay", "search")Connector

- Pre-flight reality check for on-chain AI agents. Verifies token addresses, prices, chain IDs, and contract existence before your agent acts. Catches hallucinated addresses that would cause irreversible losses. FREE: 5/day per IP, unlimited with API key. Returns: { verified: bool, hallucination_risk: 'none'|'low'|'medium'|'high'|'critical', correct_value, correction, source, confidence } Supports batch mode (up to 10 claims). Always run before any on-chain tx.Connector
- Connect a third-party provider (Zernio, Resend, GA4, Search Console, HubSpot, Stripe, Linear, Notion, Slack) to this workspace. USE WHEN the user wants to wire up publishing, email sending, or analytics readback. For OAuth providers (ga4 / search_console / hubspot) returns an authorizeUrl the agent surfaces to the user. For API-key providers (zernio / resend) returns instructions for the set-key tool. Without this, publish/send/measure tools return 'configure first' errors.Connector
