Patto

German-hosted MCP outreach workspace for PR, link building and B2B sales: contacts, campaigns, mailbox drafts and controlled send with your own AI assistant.

Parzialmente ospitato nell'UE

Patto is a Berlin-operated SaaS workspace that connects an MCP-compatible AI assistant to persistent outreach data and your brand mailbox. It is built for PR pitches, link building and B2B prospecting where the assistant does research and writing, while Patto keeps organisations, contacts, prospects, campaigns and threaded drafts across conversations.

Unlike all-in-one AI writing products that meter their own model, Patto does not run a language model. You bring Claude, ChatGPT (with MCP support) or another MCP client; Patto exposes tools over a remote MCP endpoint with OAuth and enforces send rules when drafts are released.

The concrete differentiator for European buyers is the combination of a German contracting entity (onEco GmbH), application and database hosting at netcup in Germany, a registration-time Article 28 DPA, and draft-first sending with opt-out, cooldown and limit checks before mail leaves your own mailbox.

EU-operatedRemote MCPBring-your-own AIDPA availableDraft-first email

Shortlist Patto when you want a German-hosted outreach CRM that your existing MCP assistant can drive, with draft-first sending from your own mailbox. Skip when you need a bundled LLM, purchased leads, or a full Salesforce-class CRM; consider Fireply AI for social reply automation or a conventional ESP/CRM instead.

Key capabilities

Exposes brands, organisations, contacts, prospects, campaigns, mailbox search/drafts and interactions to Claude, ChatGPT or other MCP clients over https://pattorelay.com/mcp with OAuth. The assistant researches and writes; Patto persists the operational record across chats.

Each brand has its own sender identity and mailbox. Connect IMAP/SMTP (app passwords for Google/iCloud) or, on Standard and above, Microsoft 365 via admin consent and Graph tokens. Credentials are stored encrypted; disconnect removes Patto's copy.

Store campaign briefs, link prospects, track stages (qualified, contacted, replied, interested, won) and due follow-ups. The assistant can retrieve what was sent and what came back when starting the next wave.

Every outbound message starts as a draft. Release in the app by default, or enable assistant release on paid plans. Before send, Patto checks suppression/opt-outs, recipient cooldowns, plan sending limits and duplicate-send protection. Replies are drafted inside their threads.

Patto charges for the workspace and infrastructure. Token and model costs stay with your AI provider. Useful when you already standardised on one assistant and do not want a second writing persona product.

Best fit when

  • PR, media relations or link-building teams that pitch from their own brand mailbox
  • B2B founders or small sales desks already using Claude, ChatGPT or another MCP client
  • Agencies that need multi-brand sender identities with shared contacts and per-brand opt-outs
  • Buyers who require a German contracting entity, published DPA and DE application hosting for the workspace
  • Workflows where every outbound mail must start as a reviewable draft with cooldown and suppression checks

Poor fit when

  • Teams that want an all-in-one product with a built-in writing model and metered AI credits
  • Buyers who need a purchased contact database or high-volume ESP infrastructure
  • Consumer or personal use (terms limit Patto to entrepreneurs / B2B)
  • Organisations that require public ISO 27001 or SOC 2 evidence before shortlisting
  • Use cases that must claim an EU-only processing chain including logs and operator tooling

Consider instead when

  • When: You need full CRM, pipeline reporting and ecosystem apps rather than MCP outreach tooling

    Consider: Salesforce (incumbent) or a conventional European CRM/ESP stack

    Patto is intentionally narrower than a revenue cloud.

  • When: Your outreach is social replies on X rather than email PR or link building

    Consider: Fireply AI

    Lithuanian SaaS focused on X reply automation.

  • When: You only need MCP access to analytics or creative rendering, not mailbox CRM

    Consider: AskGSC or thirds.ai

No known US parent of onEco GmbH. Core customer workspace on German netcup hosting, but Papertrail (US) and Slack (US-group) mean the processing chain is not EU-only. Indicative only, not legal advice.

Considerations & known limitations

  • MediumUS logging and US-group ops tooling

    Papertrail in the USA may receive personal data in error context; Slack operator alerts sit under a US parent. Procurement that requires an EU-only chain including observability should treat hosting as partial and review SCCs/DPF language.

  • MediumCustomer-chosen AI and mailbox providers

    Connecting Claude, ChatGPT, Microsoft 365 or other MCP/mailbox providers sends contact and email content to those vendors under the customer's instruction. Patto does not control their retention or training settings.

  • MediumOptional assistant-driven send

    When agentic release is enabled on a paid plan, an authorised MCP client can request sending. Official terms note Patto cannot determine whether a human approved each tool call; suppression and limits still apply but legal permissibility remains the customer's duty.

  • LowNo public independent security audit

    Security claims (AES-256 mailbox secrets, OAuth for MCP, audit logging) are vendor-documented; no public ISO/SOC or independent audit package was found for external verification.

  • LowNarrow product scope vs full CRM/ESP

    Patto does not replace a full CRM suite, lead database or high-volume ESP. CSV export of contacts/prospects is described as a Pro capability; confirm plan fit before migrating large datasets.

Open questions for due diligence

  • Will procurement accept Papertrail (US) and Slack/Salesforce operator paths given German app hosting?
  • Is a customer security questionnaire or penetration-test summary available under NDA?
  • Which exact netcup regions/PoPs host production versus backups, and what is backup retention?
  • For Microsoft 365 tenants with strict Conditional Access, what exemptions are required in practice beyond the published admin-consent notes?

Domande Frequenti

No. Official terms describe a hosted CRM, campaign and email workflow with a remote MCP endpoint. You supply a compatible MCP client and a mailbox. Patto does not provide a language model or a purchased prospect list; research and content come from you or your assistant.

Privacy and DPA annexes state application and database hosting at netcup GmbH in Germany. Documented sub-processors also include SolarWinds Papertrail (USA) for application logs and Slack Technologies Limited (Ireland, Salesforce parent in the USA) for operator alerts. Stripe Payments Europe processes billing. Customer-connected mailboxes, Slack channels and AI providers receive data on your instruction.

Every outbound message is a draft first. Default release is in the authenticated web UI. On a paid plan the account owner may enable release through an authorised MCP client; suppression, cooldowns and limits still apply. Official docs note Patto cannot prove a human approved each tool call when agentic release is on.

Yes. A public Article 28 GDPR DPA with onEco GmbH is published at pattorelay.com/dpa and is concluded together with the terms when you register. It lists sub-processors and technical measures, including AES-256 for mailbox secrets and workspace isolation.

Terms limit the offer to entrepreneurs and public-law entities, not consumers. Shortlist it for PR, link building or B2B email outreach that must run through your mailbox with MCP tool access. Skip it if you need an embedded LLM, a lead marketplace, consumer signup, or a full enterprise CRM suite.
