Perplexity

Run company research via this MCP Server

The `get_company_info` tool pulls live firmographic data directly into your Claude Desktop chat. You drop a company name, and your agent returns their industry, size, and location. It stops you from keeping ten browser tabs open just to research a prospect. Digging deeper takes one prompt. Ask Claude to run `get_company_tech` or `get_company_revenue` to qualify the lead. Your agent grabs the exact tech stack and revenue brackets, formatting everything into a clean table before you even ask.

Find and verify contact details

The `find_email` and `find_phone` tools let Claude hunt down direct contact information for specific decision-makers. You give the agent a name and domain. It returns the exact email and dial string you need for outreach. Bounced emails ruin domain reputations. That is why your agent runs the `verify_email` tool automatically before drafting any cold outreach. You get a confirmed address and a drafted message in a single workflow.

Pull lists from LinkedIn profiles

The `enrich_linkedin` tool translates a standard LinkedIn URL into a complete data payload. Paste the link into claude.ai, and the agent extracts the person's current role, past experience, and company details. Scaling this up requires the `bulk_enrich` tool. You can upload a CSV of profile links to Claude Desktop, and the agent processes the entire list. It spits out a clean dataset ready for your CRM.
