The Leadspace MCP connects your AI assistant directly to Leadspace's B2B data. Instead of switching tabs and copying details across tools, you just ask — "Enrich Acme Corp," or "Find the VP of Sales there and get her email" — and the answer comes straight back in your chat.

It works inside the AI tools you already use, such as Claude and ChatGPT. You ask in plain language, and Leadspace does the lookup behind the scenes. This guide walks you through setup, which takes a couple of minutes.

What you can do

Before you start: create a free Leadspace account

The MCP is available to anyone with a free Leadspace account. If you already have one (including through Sidekick), you're ready — skip to the next step.

Create your account (free)

1. Sign up at skprod.leadspace.com using your work email (personal email addresses aren't accepted).
2. That email and password is what you'll use to sign in when you connect the MCP.
3. Note: if you already use Leadspace Sidekick browser extension, you can use the same account with MCP.

Connect it to your AI

Every client uses the same address:

https://skprod.leadspace.com/mcp/v1

In Claude

1. Open Settings > Connectors and choose Add custom connector.
2. Paste the address above and leave the optional OAuth fields blank.
3. Click Connect, then sign in with your Leadspace login when the browser window appears.
4. That is it. Leadspace tools are now available — just start asking.

You can also use Leadspace MCP in Claude Code. Just follow thee steps:

1. Add the server:

   claude mcp add --transport http leadspace https://skprod.leadspace.com/mcp/v1

2. Authenticate — in Claude Code, run:

   /mcp

then select leadspace → Authenticate. A browser window opens; sign in with your Leadspace login.

3. That's it — the Leadspace tools are available. Just ask (e.g. "enrich companyname.com").

Notes: leave any Client ID / Secret blank (handled for you), and no Node.js or bridge is needed — Claude Code connects to the URL directly. This is the one non-Claude-web path you've actually verified end to end, so it's solid to publish as-is.

In ChatGPT

You can connect Leadspace directly in the ChatGPT web app. This requires a ChatGPT plan that supports custom connectors and Developer Mode (Pro or higher — custom connectors aren't available on Free or Plus).

1. In ChatGPT, go to Settings > Connectors (may show as "Apps & Connectors") and enable Developer Mode under Advanced Settings.

2. Click Create (or the + Add button) and enter:

   • Name: Leadspace
   • URL: https://skprod.leadspace.com/mcp/v1
   • Authentication: OAuth

   Leave any Client ID and Secret fields blank.

3. Click Create, then Connect, and sign in with your Leadspace login when the browser window opens.
4. Start a new chat, enable Leadspace from the + / Apps menu, and ask in plain language.

Prefer a local setup? You can also use Leadspace through OpenAI's Codex agent:

1. Make sure you have OpenAI's Codex installed (OpenAI's local agent / CLI).

2. Run the following command:

   codex mcp add leadspace --url https://skprod.leadspace.com/mcp/v1

3. Run codex mcp login leadspace, then complete the browser sign-in with your Leadspace login.
4. Ask in plain language. The Leadspace tools are now available in Codex.

You always complete the sign-in yourself. Credentials are never handed to the agent.

In Cursor, VS Code, and other clients

Leadspace works with any MCP-compatible client using the same address and your Leadspace sign-in. Client fields such as Client ID and Secret stay blank.

• Claude Desktop — Settings > Connectors > Add custom connector > paste the URL > sign in.
• Cursor — Settings > MCP > Add server > paste the URL, then authenticate with your Leadspace login.
• VS Code — using an MCP-capable extension, add a server pointing at the URL, then authenticate.

Some clients connect to the URL directly. Others use a local mcp-remote bridge on any port in the 4903–4910 range. Either way, you complete the OAuth sign-in yourself.

Signing in

You only ever sign in with your Leadspace login, the same work email and password. Leave any "Client ID" or "Secret" fields blank — those are handled for you.

Using the Leadspace MCP

Try it: things to ask

Once connected, just talk to your assistant normally. A few examples by role:

What costs credits?

Looking things up is free. You only spend credits when you ask to reveal a specific contact detail or check buying intent.

Good to know

If a detail is not on file, you are not charged. Revealing the same detail again later is free. You can always ask your assistant "what's my Leadspace credit balance?" to see where you stand.

The MCP uses your Leadspace account credit balance. The free Starter tier includes 25 credits per day, use-it-or-lose-it, resetting daily. Paid plans give you a larger monthly allotment. 

You can also earn extra credits inside Leadspace Sidekick chrome extension through audience setup, CRM connections, and referrals, or upgrade your plan at any time.

Tips for the best results

• Be specific. A full name plus the company works far better than a name alone.
• Add context such as industry or location when a company name is common, so the assistant picks the right one.
• Keep working in the same chat. Your assistant remembers the company you are looking at, so you can ask follow-ups.
• Check buying intent first when prioritizing accounts, before spending credits on contact reveals.

Troubleshooting

• Don't see Leadspace tools? Make sure you finished signing in and the connector shows as "Connected."
• Can't sign in? Use the email and password for your Leadspace account. If you don't have one yet, sign up here first with your work email.
• Out of credits? You can earn more credits from within Sidekick chrome extension, for example by completing your target-audience setup, connecting a CRM, or referring a colleague. You can also upgrade your plan (Starter, Solo, Pro, or Enterprise) for a larger credit allowance. Ask your assistant to check your balance at any time.
