LeadMagic MCP Server: Local B2B Data Enrichment Tools

A TypeScript stdio MCP server that connects AI clients to a subset of the LeadMagic B2B enrichment API. It provides 19 tools for email discovery and validation, people and company enrichment, job research, advertising data, and credits.

LeadMagic B2B enrichment · MCP setup guide · Pricing and credits

For the current hosted experience, use LeadMagic hosted MCP at https://mcp.leadmagic.io/mcp with OAuth. The Cursor plugin and Claude Code plugin configure that service.

Local installation

Use this package when your client needs a local stdio process and you intend to manage a REST API key. It does not provide the hosted server's complete search, bulk, or OAuth feature set.

npm ci --ignore-scripts
npm run build
# Set LEADMAGIC_API_KEY securely in your shell or secret manager first.
node dist/index.js

Configure your MCP client to launch node with the absolute path to dist/index.js and provide LEADMAGIC_API_KEY through the client's secret or environment mechanism. Do not commit literal keys. Source changes here do not update already published npm packages.

API behavior

  • REST calls use https://api.leadmagic.io, documented /v1/ routes, and X-API-Key.

  • Credits use GET /v1/credits and consume no credits.

  • HTTP failures are returned as errors; redirects are rejected to avoid forwarding credentials.

  • Diagnostics go to stderr and omit API-key fragments and upstream error payloads.

  • Requests time out after 30 seconds by default. Paid requests are not automatically retried.

  • Email Finder returns validated work emails. Validate externally sourced emails separately.

See API documentation and credit costs. Tool and package changes should be tested with a small, authorized sample before production use.

Development

npm ci --ignore-scripts
npm run validate
npm test

Tests use a mocked HTTP adapter and do not consume credits.

    B3.2/5.0

    Scored across 19 tools

    Disambiguation4/5

    Tools have largely distinct purposes, with clear input/output differences between email lookup variants, profile lookups, company search, and ad searches. A few related tools (find_email vs. social_to_work_email, search_company vs. get_company_funding) could be confused at a glance, but descriptions provide enough separation.

    Naming Consistency4/5

    Most names follow a predictable snake_case verb_noun pattern (find_email, search_company, get_credits). Minor deviations like social_to_work_email and email_to_profile are still descriptive and snake_case, but break the verb-first convention slightly.

    Tool Count4/5

    With 19 tools spanning email enrichment, profiles, companies, jobs, and ads, the count is slightly heavy but reasonable for the platform's breadth. Each tool appears to own a distinct operation rather than duplicating another.

    Completeness4/5

    The surface covers core B2B lead generation workflows: validation, email finding, profile/company lookup, jobs, mobile numbers, and ad intelligence. Minor gaps exist, such as detail endpoints only for B2B ads rather than Google/Meta ads, but agents can still complete most workflows.
