## HubSpot Breeze AI & Agent Hub

HubSpot's artificial intelligence ecosystem—branded across the platform as Breeze AI and managed centrally through Agent Hub—embeds autonomous go-to-market agents directly into the HubSpot Smart CRM. Because every agent operates natively on live contact records, deal timelines, call transcripts, and support tickets, teams can deploy AI across marketing, sales, and service without complex data pipelines or external middleware.

In 2026, Agent Hub serves as the command center for monitoring prefabricated and custom AI teammates. Its specialized roster includes the Customer Agent (which autonomously resolves over 65% of support inquiries across chat, email, and beta voice calling), the Prospecting Agent (which monitors buyer intent signals and drafts personalized outreach), the Content and Campaign Agents (which turn a single marketing goal into multi-channel blog posts, landing pages, and nurture sequences), the Data Agent (which answers custom research questions across CRM records and documents), and the Revenue Agent for automated invoice follow-ups.

Teams that need bespoke workflows can use the no-code Agent Builder canvas to assemble custom agents grounded in proprietary prompts, knowledge bases, and third-party app integrations, accessible anywhere via Breeze Assistant. HubSpot also introduced Answer Engine Optimization (AEO) tools to track brand visibility inside AI search engines, alongside an outcome-based credit model announced in April 2026 that charges $0.50 only when the Customer Agent successfully resolves an inquiry.

**Pricing & Plans:** Breeze Assistant and foundational AI writing tools are included on Free and Starter ($15/seat/month with 500 HubSpot Credits); autonomous agents in Agent Hub require Professional ($800+/month, 3,000 monthly credits included) or Enterprise ($3,600+/month, 5,000 credits included), where Customer Agent costs 50 credits ($0.50) per resolved conversation, Prospecting Agent costs 100 credits ($1.00) per recommended lead, and extra credits cost $10 per 1,000 ($9/1,000 billed annually).

- **Centralized Agent Hub & No-Code Agent Builder:** Monitor live status and ROI across your entire AI workforce in one dashboard, or build custom CRM-grounded agents on a visual no-code canvas.
- **Outcome-Billed Breeze Customer Agent:** Resolve repetitive support tickets 24/7 across web chat, email, forms, and voice using live contact and contract history, billed at 50 credits ($0.50) only upon verified resolution.
- **Autonomous Prospecting & Smart Deal Progression:** Watch target accounts for buying signals, trigger personalized outreach automatically, and generate post-call CRM updates and next-step recommendations.
- **Campaign, Content & Nurture Marketing Agents:** Plan multi-channel campaigns from a single goal in one session, generate brand-voice blog posts and landing pages, and tailor lifecycle nurture emails per contact.
- **Data Agent & Answer Engine Optimization (AEO):** Query CRM records, call transcripts, and PDFs 10x faster with the Data Agent while tracking how AI answer engines cite and rank your brand via HubSpot AEO.

**Strengths:** Zero data integration friction—agents read and write directly to HubSpot Smart CRM contacts, deals, calls, and tickets from day one.; Fair April 2026 shift to outcome-based pricing ($0.50 per resolved conversation) makes the Customer Agent one of the lowest per-resolution rates in the market.; Included credit pools on Starter (500), Professional (3,000), and Enterprise (5,000) let teams test AI agents before buying extra credit packs.; Strong enterprise governance with SOC 2 Type II compliance, published AI model cards, and strict zero-training policies with external LLM vendors.

**Limitations:** Autonomous agents like the Customer Agent require expensive Professional ($800+/mo) or Enterprise ($3,600+/mo) base subscriptions plus mandatory onboarding fees.; All Breeze AI agents and data enrichment features draw from a single shared HubSpot Credits pool, making multi-agent budgeting tricky to predict.; Customer Agent voice calling remains in beta and is metered separately at $0.50 per minute.

## MCP Search (MCP Stack)

MCP Search, live on the mcp-stack.com domain, targets a specific and often underserved job: producing very fine-grained B2B prospect lists for the French market rather than running a global people search. Instead of stacking dozens of filters, you describe your target in a sentence — for example, sales directors who graduated from an engineering school, have worked in manufacturing for at least three years, and are employed at companies that are still active. The engine cross-references legal registry records (INSEE, Infogreffe, BODACC), verified Google Maps listings, public LinkedIn company profiles, open web contact data and financial filings to return a structured list.

The dataset is positioned as a pre-crossed French prospecting base: roughly 27 million legal entities, about 29 million profiles and professional experiences, and around 1.4 million establishment-level records usable in the same query. Job-posting signals from boards such as LinkedIn, Welcome to the Jungle, Pôle emploi and Indeed are announced as coming next.

The product is currently in a waitlist phase with a September launch; the company states that the MCP connector for Claude, Grok or home-built agents is not yet publicly callable and will expose the same France-first list engine when it opens. It positions itself against Apollo (global outbound) and Clay (multi-provider enrichment) rather than against infrastructure tooling. MCP Search is an independent product and is not produced or endorsed by Anthropic, xAI or any model provider.

**Pricing & Plans:** Pricing is not published on the current site. The product is in a waitlist phase ahead of a September launch, and no public plan, trial or per-seat figure is listed yet — check the site for updates when the product opens.

- **One-sentence list building:** Describe your target in plain French and get a cross-referenced list, instead of stacking 8+ filters across NAF codes, revenue thresholds and tenure.
- **Multi-source French data:** Crosses legal registry records (SIREN/SIRET, officers, financials), Google Maps establishments, public LinkedIn company data and open web contacts.
- **Large FR-first coverage:** Around 27M legal entities, roughly 29M profiles and experiences, and about 1.4M establishment records accessible within the same query intention.
- **MCP connector for AI agents:** An MCP endpoint designed so Claude, Grok or a custom agent can run the same fine-grained French account queries, planned for public release at launch.
- **Direct competitor framing:** Explicitly positioned against Apollo-style global people search and Clay-style enrichment workflows, focusing on crossed French list building as the core job.

**Strengths:** Focuses on a genuinely hard problem: fine-grained, cross-referenced French B2B lists rather than generic global people search; Aggregates several authoritative French sources (legal registry, Maps, LinkedIn, financials) into a single intention-based query; Plans an MCP connector so the same list engine is callable by AI agents; Transparent comparison pages against Apollo, Clay and French data providers

**Limitations:** Currently in a waitlist phase, so the core product and MCP tools are not yet publicly usable; No public pricing published, which makes budgeting hard to plan; Coverage is France-specific, so it is not suitable for multi-country outbound
