# LeadLex MCP server

> Connect Claude, ChatGPT, Cursor and other AI assistants to your LeadLex workspace.

The LeadLex MCP server lets an AI assistant work inside your LeadLex workspace. You ask in plain language. The assistant searches your contacts, creates a deal, books a follow-up task or drafts a campaign, and it does so with your own CRM data.

MCP (Model Context Protocol) is the open standard that AI assistants use to talk to outside tools. LeadLex runs a remote MCP server, so there is nothing to install.

## Endpoint

```
https://mcp.leadlex.com/mcp
```

The server speaks streamable HTTP. You can sign in with OAuth 2.1 or with a workspace API key. See [Authentication](/mcp-server/authentication.md).

## What the server exposes

> **[99 tools](/mcp-server/tools.md)**
>
> Contacts, companies, deals, tasks, meetings, notes, email, campaigns, prospecting, reports and more.

> **[5 resources](/mcp-server/resources-and-prompts.md)**
>
> Read-only records the assistant can load on demand, such as a workspace snapshot.

> **[6 prompts](/mcp-server/resources-and-prompts.md)**
>
> Ready-made workflows such as a weekly pipeline review.

## Connect your assistant

> **[Claude](/mcp-server/connect-claude.md)**
>
> Claude.ai, Claude Desktop and Claude Code.

> **[ChatGPT](/mcp-server/connect-chatgpt.md)**
>
> Add LeadLex as a custom connector.

> **[Cursor](/mcp-server/connect-cursor.md)**
>
> Add LeadLex to your Cursor MCP config.

> **[Other clients](/mcp-server/connect-other.md)**
>
> Any client that supports remote streamable HTTP servers.

## How it relates to the REST API

The MCP server and the [REST API](/api-reference/contacts/list.md) work on the same workspace data. Use MCP when an AI assistant is the user. Use the REST API when your own code is the client.

## Workspace isolation

Every call runs inside the workspace of the account that signed in. You never pass a workspace or company id, and the tools do not accept one. Read more on the [Security](/mcp-server/security.md) page.

## Availability

MCP is included on every LeadLex plan. OAuth connections can make 60 tool calls a minute; above that the server answers `429` with a `Retry-After` header.
