What Firmbase's MCP integration means for your sales workflow
By Dave Curran, Co-Founder, Firmbase | March 2026 | 6 min read
If you've been reading about AI assistants and Model Context Protocol (MCP), you've probably seen it mentioned as a big deal. But if you're not deep in AI infrastructure, it's not immediately clear why you should care.
Here's why: MCP lets you talk to your sales tools in plain English, and have an AI assistant query them directly - without switching tabs, without manual data entry, without the friction that usually comes with integrations.
What MCP actually is (in one paragraph)
MCP is an open standard that lets AI assistants connect directly to tools and data sources. Instead of you having to grab data from five different tabs and paste it into a document, you ask your AI assistant a question in plain English, and it queries those tools directly to answer it. Think of it like giving an AI assistant the ability to use your software stack.
What this means for Firmbase users
With MCP integration, you can ask Claude (or any MCP-compatible AI) questions about your Firmbase data directly:
"Which of my target accounts have shown a buying signal in the last 30 days?" - The AI queries Firmbase and gives you a list with context.
"Find 20 IT consultancies in Manchester with revenue between £2M and £10M that have appointed a new director this year." - The AI searches Firmbase using your exact criteria and surfaces matching accounts. No manual filtering.
"Show me the top 10 accounts in my universe that are showing three or more buying signals this month." - The AI applies signal weighting, ranks accounts, and surfaces your priority list.
Why this matters for sales workflows
Most sales workflows involve a lot of tab-switching and copy-pasting. With MCP integration, it's one conversation:
"I'm about to reach out to Example Ltd. Pull their latest Companies House data, show me the buying signals we've identified, tell me who their leadership team is, and suggest an outreach angle."
The AI does the work. You get a one-page brief. You write your email. Done.
Real examples of what this enables
Building a weekly priority list: "Give me the top 20 accounts in my target universe that are showing buying signals this week, sorted by signal strength. For each one, tell me what signals they're showing and suggest the next action." That's a 30-minute task if you do it manually. It's five seconds with MCP.
Researching before a cold call: "I'm calling the Managing Director of Example Ltd this afternoon. What do I need to know? Pull their recent Companies House filing, show me if they've hired anyone recently, tell me what job postings they've got open, and suggest what pain points they might have based on their growth pattern."

FAQ
Do I need to be technical to set up MCP?
No. If you can connect an app to your email, you can set up MCP integration. It's a few clicks.
Will this work with other AI assistants besides Claude?
MCP is an open standard, so yes - any AI assistant that supports MCP can integrate with Firmbase.
Is my data secure if I'm querying it through an AI assistant?
Yes. Your data stays within your Firmbase instance. The AI queries it, reads the response, and that's it.
How is this different from just exporting data from Firmbase?
Exports are static - you export once and the data gets old. MCP queries are live - you ask a question and get real-time data.
