## Clay

Clay brings together the three pillars of modern go-to-market work: data, reasoning, and activation. On the data side, its marketplace lets you buy and combine records from more than 200 providers under a single contract, with waterfall enrichment that queries multiple sources and keeps the best match. Signals and intent tracking surface job changes, promotions, and buying activity so you know when an account is actually in-market.

On top of that data layer, Clay runs agentic workflows. Its global agent and account agents research companies and people with AI, score and route leads, and write personalized outreach — and you can chain these steps into long-form automations or call them through the CLI and API. Because the same canvas handles enrichment, scoring, and messaging, teams stop stitching together spreadsheets, point tools, and scripts.

The activation layer is what makes the platform practical: sync targeted audiences to LinkedIn, Meta, and Google Ads, push enriched records back into your CRM with reverse ETL, or send personalized sequences through Clay's native sequencer. Clay is aimed at GTM ops, sales, marketing, and enterprise teams that want a repeatable, testable system rather than a pile of one-off campaigns.

**Pricing & Plans:** Clay uses flexible, plan-based pricing with a 14-day free trial and a free entry point for individuals getting started, while larger teams and enterprises are quoted based on seats, credits, and data usage. Contact Clay for detailed enterprise pricing.

- **Waterfall data enrichment:** Query 200+ data and AI providers from one contract and cascade across them to maximize coverage and accuracy.
- **Agentic research & scoring:** Clay's global agent and account agents research companies and people with AI, then score and route leads automatically.
- **Signals & intent tracking:** Monitor job changes, promotions, hiring activity, and other buying signals to target accounts at the right moment.
- **Workflow orchestration & CLI/API:** Chain enrichment, reasoning, and outreach into long-running workflows, or build programmatically with Clay's CLI, API, and MCP tooling.
- **Multi-channel activation:** Sync audiences to LinkedIn, Meta, and Google Ads, push data back to CRM via reverse ETL, and run personalized sequences natively.

**Strengths:** Unifies data enrichment, AI research, and multi-channel activation in a single platform; Marketplace with 200+ providers and waterfall enrichment delivers strong coverage; Powerful workflow automation with CLI, API, and MCP access for technical teams; Large, active community plus Clay University, livestreams, and education resources

**Limitations:** Steep learning curve — the flexible canvas can overwhelm new users; Credit-based data usage costs can scale quickly for high-volume teams; Enterprise pricing is quote-based, which complicates budget planning

## 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
