Not in the grid because nothing is read from them: Slack, Telegram and Email are destinations. Each one lets Cursor send to the place you linked. A message goes out as soon as it is sent. Switch on Ask before sending to approve each one first; an email to an address you did not save always waits for you.
Why one server rather than four
A project's mcp.json can list a server per account, and Cursor will call each of them. The catch is the question that spans two: Cursor has to join them in the chat panel, with no idea that one account's conversion is another's purchase. One entry reaches every account from one sign-in, instead of a server per account to keep running.
Held against the two alternatives worth naming: HeyMetra vs AdKit, an MCP server for ad accounts alone, and HeyMetra vs Supermetrics, which lands a copy of the data somewhere rather than answering out of the account.

Your assistant tells you in one line what it will change, and nothing reaches the account until you say yes in the chat. HeyMetra cannot undo a change afterwards.
Adding one in Cursor
See the setup
Why Cursor: A file you can commit. If a colleague clones the repository, the connection comes with it.
Worth knowing for Cursor: Leave the static OAuth fields empty; HeyMetra does not need them.
Authorize the accounts you want reachable. This happens once, in HeyMetra, and is the part that is the same wherever you ask. No HeyMetra account yet? The trial covers this step.
Ask Cursor something that needs one of the accounts. The model picks the tool; you never name it.
These interfaces move, and this one has moved before. Where a step here disagrees with what is on your screen, trust the screen. Then check Cursor's own documentation, which is what these steps were written from. And tell us, so the page stops being wrong for the next person.
Use it from the Cursor subscription you already pay for.
Pricing
There is no second model to buy here. The answering happens in Cursor; HeyMetra supplies the accounts and asks you before anything in them changes.
~/.cursor/mcp.json, or .cursor/mcp.json in a project. The server is one entry in it, and the key that holds the address is url.
Is there anything specific to Cursor I should know?
Leave the static OAuth fields empty; HeyMetra does not need them. Everything else is the same as it is anywhere else: one address, the sign-in you already have, and the tools appear.
Which Cursor plan do I need?
Individual, Teams or Enterprise. That is Cursor's own requirement for adding a server, separate from your HeyMetra plan, which works the same whichever assistant you use.
Does Cursor support MCP?
Yes. Cursor reads MCP servers from an mcp.json file: one per project under .cursor/, or a global one in your home directory.
Where do I add an MCP server in Cursor?
Cursor reads MCP servers from an mcp.json file: one per project under .cursor/, or a global one in your home directory. After that, Cursor discovers the tools the server exposes and decides which to call while it answers you. You never name a tool.
Is a remote MCP server different from a local one?
Yes. A local one runs as a process on your own machine and stops when you close Cursor. A remote one runs on the operator’s infrastructure and is reached over HTTP, so there is nothing to install and nothing to keep running, and the credentials live with the operator.
Can an MCP server change my accounts?
Only if you said it may. Connecting an account to HeyMetra asks that question once: read-only, or may the assistant propose changes there too. An account left read-only carries no tool that can change anything, and Search Console and Jira connect read-only with no option to change. Where you said yes, Cursor tells you in one line what it will change and waits; nothing reaches the account until you say yes in the chat. A message to a channel you linked goes out when it is sent, unless you switch on Ask before sending.
Other AI assistants
The same connection, from any of them. What differs is where the setting lives and what that app calls it: Cursor says “MCP servers”.
MCP is an open standard that lets an AI assistant reach the apps and accounts you already use. What it is, where it came from, how it works, what it changes.
An MCP connector is one authorized account behind an MCP server. How a standard connector differs from a custom one, and when you need the second.
