Connect ChatGPT or Claude

ChatGPT

1. Open Settings → Apps & Connectors (in some versions Plugins), then Advanced → Developer mode.
2. Choose Create (or Add → Create MCP App). Name: Mktly. MCP server URL: https://mktly.ai/mcp. Authentication: OAuth. Confirm the warning about custom servers and create.
3. Click Continue to Mktly, sign in with your Google account, press Allow access, then Finish connecting.
4. In a chat, pick Mktly from the “+” menu or start with “Using Mktly, …”. Keep the plugin permission on Allow low-risk tools: reads run freely, changes ask you first.

Claude

1. Open Customize → Connectors → Add → Add custom connector. Name: Mktly. MCP server URL: https://mktly.ai/mcp. Leave the authentication defaults (“Sign in now”, “Register automatically”) and press Add.
2. Press Connect, sign in with your Google account and press Allow access; Claude returns to the connector page.
3. Under Tool permissions, set the read-only tools to Always allow and keep Google write on Needs approval. If Mktly is off in a chat, enable it in the tools menu.

What the assistant gets

Seven tools: list_resources, describe_method, google_read, gaql_search, google_write, dataset_read, fetch_page. There are no pre-made reports: the assistant reads the official method contracts and composes the requests itself. A change always goes through a dry run and needs your explicit yes in the conversation.

The Google APIs behind the tools

google_read and google_write call methods of these official REST APIs by their Discovery ids (for example analyticsdata.properties.runReport); describe_method returns each method's contract from the same Discovery documents. Mktly adds nothing to the data and removes nothing from it.

• Google Analytics 4 — Data API v1beta (reports) and Admin API v1beta (properties, key events, audiences, links)
• Google Tag Manager — Tag Manager API v2 (containers, workspaces, tags, triggers, variables, versions)
• Google Ads — Google Ads API (REST); gaql_search runs GAQL through customers.googleAds.search
• Search Console — Search Console API (search analytics, sitemaps, URL inspection)

Access uses the OAuth scopes you grant on Google's screens; the privacy policy lists what Mktly stores.

First things to try

• “Using Mktly, list my resources” — checks the connection and shows what the assistant may use.
• “Sessions by channel for the last 28 days from my GA4 property” — a first read.
• “Prepare a new key event in GA4 called contact_form, but don't execute yet” — a first dry run; nothing changes until you agree.
