LeadSmarts MCP MCP server

The LeadSmarts MCP server enables AI agents to qualify B2B leads by submitting lists for live web research. Agents can import leads, monitor research progress, and retrieve verdicts (Hot, Warm, Cold) with sourced evidence. It also supports generating outreach drafts and managing CRM matches, allowing agents to automate lead prioritization while keeping human oversight for final actions.

Claude Code configuration

claude mcp add --transport http leadsmarts-mcp https://mcp.leadsmarts.app

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration
