An official MCP server for Derrick that enables AI agents to perform B2B prospecting tasks. It allows users to find leads, verify work emails and phone numbers, enrich company data, and check tech stacks using natural language prompts.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http derrick-mcp https://app1.derrick-app.com/mcp

Codex

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

Codex configuration
