MCP Search (MCP Stack)

Hyper-targeted B2B prospect lists for France, built for teams and AI agents

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.

Strengths & Pros

+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
