Firmable Launches MCP to Connect ChatGPT, Claude, and Cursor to Verified B2B Sales Data

Most sales reps already use AI tools. The problem is those tools are only as good as the data behind them — and for most teams, that data is stale, duplicated, or flat-out wrong. Firmable’s new MCP server is a direct attempt to fix that gap.

The company has launched its Model Context Protocol (MCP) server alongside a new hub called Firmable Connect, giving revenue teams a way to pull verified B2B company and contact data directly into the AI tools they’re already using — ChatGPT, Claude, Cursor, and others.

Key Highlights

Firmable MCP pipes verified B2B data straight into ChatGPT, Claude, and Cursor
540 pre-built skills add guardrails so AI cannot quietly corrupt your CRM
Firmable Connect unifies MCP, webhooks, CRM sync, and API for GTM automation

The Practical Takeaway

The MCP trend is moving fast, and the quality of what gets connected to these protocols varies enormously. Firmable’s bet is that verified, continuously refreshed data — delivered with built-in guardrails — is worth more to a sales team than raw AI capability alone.

If your team is already using Claude or ChatGPT for prospecting and keeps running into data quality problems, this is worth a close look. The free trial makes it easy to test whether the coverage and freshness actually hold up in your market before committing.

This is especially relevant for teams focused on Lead Scoring & Prospecting.
