Leadspace MCP
Verified B2B Data, Right Inside Your AI
Ask Claude, ChatGPT or Cursor to find the right buyers, research an account, reveal verified contact details and send the list to your CRM, without leaving the conversation.
What It Does
Your whole GTM workflow, in one conversation
The Leadspace MCP connects your AI assistant to The GTM Data Intelligence Cloud™. Search, research, reveal and activate verified B2B data in plain language, with no tab-switching and no copy-paste.
Account Intelligence
Industry, size, revenue, location, industry codes and the full corporate family tree for any company.
Free
Verified Contact Data
Look up anyone from an email, LinkedIn profile or name, then reveal a verified business email or direct-dial and mobile number on demand.
1–3 credits per reveal
Buying Intent
See which topics a company is actively researching right now, so you know who is in market before you reach out.
Free
Prospect Search
Find people and companies by title, seniority, industry, size, location, technology used or intent topic, and get lookalikes of your best contacts.
Pro and above
Account Research
Buying signals such as funding, hiring and job changes, the buying group at an account, recent LinkedIn activity and whether a record is already in your CRM.
Pro and above
Lists, Export and CRM
Save any search as a list, then export it to CSV or send it straight to Salesforce or HubSpot using your existing field mapping.
Pro and above

Who It's For
Ask for it the way you’d say it
No commands to learn. Your assistant turns a plain-English request into the right searches, lookups and reveals.
Sales
“Find VPs of Sales at US software companies with 500+ employees and get the email for the top match.”
Account Executives
“Any buying signals at Northwind? Who else should I talk to there, and are they already in Salesforce?”
Marketing
“Save marketing directors in Germany at 1,000+ employee companies as a list and export it to HubSpot.”
RevOps
“Enrich this list of inbound sign-ups and flag the ones at companies over 1,000 employees showing buying intent.”
Pricing
Free to start. Pay only for reveals.
Looking things up, checking intent and searching are free. You only spend credits to reveal a contact detail, and anything you’ve already revealed stays free.

One balance everywhere
The MCP uses the same credits as Sidekick and the Leadspace website.
Starter: 25 credits a day
Paid plans include a larger monthly allowance.
Pro and above
Unlocks search, account research, lists and export to CSV or your CRM.
Built for Teams
Your AI gets your access. Nothing more.
The MCP runs on the same permissions, credits and records as the Leadspace website, so an assistant can never see or do more than you can.
Your own sign-in
Secure OAuth with your work account. No API keys to share, and credentials never reach the AI.
Same permissions
List visibility, export limits and admin actions follow your role, exactly as on the website.
Cost before credits
Your assistant shows what a reveal will cost and checks your balance before spending anything.
Confirm before changes
Deleting a list, inviting a teammate or exporting with reveals always waits for your go-ahead.
