# Use Wavegrain from Make

> Call Wavegrain tools from a Make scenario with Make's MCP Client app and an access key.

> Index of these docs: https://wavegrain.com/developers/llms.txt

Make has an MCP Client app that calls a remote MCP server.
Its "Call a tool" module runs one named tool; "Execute an action with AI" lets a model pick the tools.

1. Make an access key in Wavegrain Settings with only the permissions the scenario needs.
2. In Make, add an MCP Client module and create a connection with "+ New MCP Server".
3. Server URL: `https://wavegrain.com/api/mcp`. Paste the access key in the "API Key / Access token" field.
4. In "Call a tool", pick `list_slideshows` and run the module once.

We have not tested Make against Wavegrain yet, and Make does not say how it sends the token.
Wavegrain needs it as `Authorization: Bearer <key>`; if Make sends it another way, the call answers `401`.
Tell us at support@wavegrain.com if it fails.

A scenario must never approve or post.
It makes drafts and Calendar slots; you approve them in Wavegrain.
