# Leadbase

> Find best-fit B2B companies, research your ICP and reach decision-makers with verified emails and direct numbers. Try Leadbase with 200 starting credits.

## Agent setup

Leadbase brings company, people and web research into your AI chat. Ask for the result you need: contact details, company profiles, open jobs, public social posts or a whole researched list. Leadbase selects the tools, researches missing information and returns structured results with sources.

### What you can do after connecting

- Find the LinkedIn profile and business contact details of a person from their name and company.
- Find a company’s open jobs or recent public posts, with links and dates.
- Research the official careers pages for a list of companies and return one URL per company with supporting sources.

When helping a user connect, briefly explain the relevant possibilities above and offer two or three concrete starter requests in their language. Use the native MCP connection below and user-approved OAuth. Verify the discovered tools with a read-only call such as billing_get; report connection status accurately. Once connected, offer a next step that fits the user’s goal. Setup alone does not authorize paid research.

MCP: https://www.leadbase.io/api/mcp (Streamable HTTP, OAuth)
