Watch it work on Clay
Ask in plain English. Your AI reads Clay with real MegaMCP tools, then hands you a plan. Nothing moves until a person clicks Approve, and supported changes can be undone.

Try “Show the clay operations available to this client.” Reports answer straight away. Anything that changes Clay comes back as a plan for you to approve.
Safety
Hand AI the keys. Keep the brakes.
The same loop guards every MegaMCP connection: ask, see the diff, approve, undo.
Approval before every change
Clay write tools never touch Clay directly. They return a plan, and a person approves it in the dashboard, or in chat if an admin allows it.

A diff first
Every plan lists each change with its before and after values, so you see exactly what will move before it does.

Undo for supported changes
Supported changes reverse through a separately reviewed undo plan. Anything that can't be undone is marked before you approve it.

Receipts for everything
Platform checks stop stale edits, and the flight recorder logs every tool call, plan and approval, with who did it and from which AI app.

FAQ
Clay MCP server questions
Is there an official Clay MCP server?
Yes. As of October 2026, Clay publishes an official MCP server for find-and-enrich tools and Functions. MegaMCP's native connection uses Clay's public REST API, with authorized Enterprise table reads and reviewed routines. It does not relay every tool from Clay's hosted MCP server or invent unsupported table-edit operations.
What is a Clay MCP server?
An MCP (Model Context Protocol) server lets AI assistants such as Claude, ChatGPT and Cursor use Clay through tools. MegaMCP's hosted Clay MCP server gives your assistant 2 read tools and 1 write tool for authorized Enterprise table fields, credit balance, routine results and supported workflow queries, and every change waits for a human approval.
Does the Clay MCP server work with ChatGPT?
Yes. MegaMCP is a remote MCP server with OAuth sign-in, so one URL works in ChatGPT (as an app, with developer mode on), Claude (as a custom connector), Cursor, Claude Code and VS Code. Your AI app's own plan decides whether it can add custom MCP servers.
Can it make changes to my Clay account?
Yes, with your approval. It can propose supported searches and enrichment routine requests after review changes. Each one comes back as a plan with a line-by-line diff and waits for a human before anything moves. Fixed vendor-workspace client scope. Exact proposals, provider quota and no replay of uncertain writes. Credential administration, billing, permanent deletion and binary transfers remain in the vendor dashboard.
How do I connect Clay to Claude or ChatGPT?
Customer API key and authorized table IDs. Structured tables require Enterprise access.
What does the Clay MCP server cost?
Reading Clay is free on MegaMCP's Free plan (100 reads a day, no card). Approved changes are included in every paid plan, from $19/month after a 5-day free trial, with unlimited runs and no credits. MegaMCP adds no markup: any subscription or API usage with the vendor stays between you and them.
Is my Clay data safe?
Your Clay credentials are encrypted at rest (AES-256-GCM) and bound to their connection, and MegaMCP never trains AI models on your data. Your AI only sees the accounts you switch on, members limited to certain clients only see those clients, and every tool call lands in the flight recorder.
