# MCP Server

> Use every Seamless.AI API as agent tools in Claude, ChatGPT, Cursor, VS Code, and any MCP client: 57 tools across search, research, and outreach.

> [!NOTE]
>
> **Server URL** `https://mcp.seamless.ai/mcp` · **Auth** OAuth 2.1 or API key · **Credits** same as the matching REST API

## Introduction

The Seamless.AI MCP server exposes the catalog as tools an AI agent can call directly: search contacts and companies, research them, manage lists and saved searches, build campaigns, send email, log calls, and read activity. Your agent picks the right tool from a plain-English request, with no API code to write.

| Tool domain | Tools | Matching REST API |
| - | - | - |
| Search | `search_contacts`, `search_companies`, `lookup_locations` | [Contact Search](/api-catalog/contact-search), [Company Search](/api-catalog/company-search), [Location Lookup](/api-catalog/location-lookup) |
| Research | `research_contacts`, `research_companies`, `poll_contact_research`, `poll_company_research` | [Contact Research](/api-catalog/contact-enrichment), [Company Research](/api-catalog/company-enrichment) |
| User | `get_credits`, `get_my_contacts`, `get_my_companies` | [My Contact Data](/api-catalog/my-contact-data), [Account](/api-catalog/account) |
| Engagement | Lists, saved searches, campaigns, templates, email, calls, tasks, activity | [Engagement API](/api-catalog/engagement) |

The full tool list is in the [MCP docs](/mcp-docs).

## Connect

```json Claude Desktop / Cursor theme={null}
{
  "mcpServers": {
    "seamless": {
      "url": "https://mcp.seamless.ai/mcp"
    }
  }
}
```

```bash Claude Code theme={null}
claude mcp add --transport http seamless https://mcp.seamless.ai/mcp
```

On first connect, the client opens a browser window to log in to Seamless.AI. Clients without OAuth can [use an API key](/mcp/authentication). See the [install guides](/mcp/install/cursor) for each client.

## AI agent prompt

Once connected, try:

```text theme={null}
Find 25 VPs of Sales at SaaS companies with 200-1,000 employees in Texas that use Salesforce,
research the top 10, and add them to a new list called "Q4 Texas RevOps".
```

## Access

MCP must be enabled on your account. Engagement tools need a Connect license. See [Access control](/mcp/access-control) and [Risk tiers](/mcp/risk-tiers).
