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 [Profile (Markdown)](https://openaitools.app/tool/mcp-stack.md) ## Success.ai Success.ai is a B2B sales platform built around an AI-assisted prospecting and outreach workflow.
