Authenticate with your Seamless account in a single click.
Prompt away
Ask your agent to find buyers. Tools show up automatically.
Built for the way real teams ship
Every call runs as you — scoped to your license, your credits, and your permissions. Nothing runs, sends, or deletes without the guardrails your security team already expects.
- Read — looks things up · runs on its own
- Write — creates or sends · asks you first
- Destructive — deletes for good · needs explicit OK
Scoped to your license
Every request runs as the signed-in user. Your client only lists the tools your license and Connect access allow.
Risk-tiered tools
Every tool is labeled read, write, or destructive, with SDK hints so clients can gate side effects before a call runs.
Human in the loop
Turn on confirmation for write and destructive tools. Destructive actions can't be undone — so your agent asks first.
OAuth 2.1 + PKCE
No shared keys. Tokens refresh automatically and can be revoked any time.
The verified data your agent runs on
Seamless MCP is built on the same platform sales teams already rate among the best in sales intelligence.
I love how accurate their data is, the ease of use for their platform and how quick I am able to research my prospects. Support is paramount in this area and they have it all. Ease of implementation helps a lot. The software is frequently used by my staff. Their integration helps with workflow into our other SaaS stacks.
I appreciate that it is real-time AI data. Other vendors store data and only review it once every 60 days or quarter, making much of the data stale. The UI/UX is clean. The system is easy to use. I have used other competitors and find the accuracy of this data to be far superior.
I specifically like the ability to select parameters that fit the profile of your ideal client, and even more so the ability to identify consumers that may be looking for services that fit your scope of work.
What is Seamless MCP?
The Seamless MCP server connects your AI agent to verified B2B data and outreach — 54 tools across 11 domains, from search to send. Point any MCP client at https://mcp.seamless.ai/mcp and go. Review our Knowledge Base to see how the Seamless MCP works.
How long does setup take?
About 60 seconds. Add the server URL to your client, sign in with OAuth, and run your first search. Read the quickstart guide to learn more.
Which clients does it work with?
Claude Desktop, Claude Code, Cursor, VS Code, ChatGPT, Windsurf, Gemini CLI, Cline, Amazon Bedrock, Amazon Q, BoltAI, and any MCP-compatible client. Review our docs to see a list of all install guides.
Does it cost credits?
Search is free. Credits apply only when you enrich a contact or company.
Can my AI send email on my behalf?
Only when you approve it. Sending is a write action, so your agent confirms before every send. Please note emailing requires you to have Connect enabled and have Connect access on your account.
Is my data secure?
Every request runs as the signed-in user, scoped to your license. Write and destructive tools require confirmation, and OAuth tokens refresh automatically. Review how access control works in our docs.
Do I need a developer?
No. OAuth auto-discovery means most clients register with just the server URL — no code, no manual wiring. Review the docs on how OAuth authentication works.
Where is the server URL, and is there a GitHub version?
The server lives at https://mcp.seamless.ai/mcp — that's all most clients need. For hands-on setup, the install guides cover Claude, Cursor, VS Code, and more at docs.seamless.ai/mcp-docs.
Do I need MCP access enabled on my account?
Yes. MCP must be enabled for your account. It should be on by default. If you see “MCP Server access is not enabled,” contact your administrator or Seamless support.
