AI Actions/Zapier MCP

  I'm unable to authenticate the Zapier MCP server with Claude Code. The OAuth flow completes successfully (I receive the callback with authorization code), but the token exchange fails with an HTTP 500 error.  Error details:  HTTP 500: Invalid OAuth error response: SyntaxError: JSON Parse error: Unrecognized token '<'Steps I've taken:  1. Generated a new API key from https://mcp.zapier.com  2. Removed and re-added the MCP server with the new token  3. Completed the OAuth authorization flow (success screen appeared)  4. Restarted Claude Code  The connection shows "connected" but "not authenticated" due to the 500 error during token exchange.  Environment:  - Client: Claude Code v2.0.76  - MCP URL: https://mcp.zapier.com/api/mcp/mcp  - OS: macOS  This appears to be a server-side issue with the OAuth token endpoint. Please advise.

I need assistance making a formstack to Google Drive automation. I want the submissions forms to be saved as a Google Drive, with the clients corresponding name and the attachments to save with attachments being named as well.   

Hi,Is there any way to integrate Google Gemini with Zapier Webhooks or MCP?I want to start Zaps with Google Gemini, for instance with voice commands.

I set up an MCP server on Zapier to connect to Kantata. I am using Claude to connect with that Zapier MCP Server to create a Kantata project from a series of prompts. It is successfully creating the project, however there are still several issues with field values and I am looking for some guidance:Start date - I am passing a date but it is being left blank. It does, however, successfully set the Due Date with the value I am passing Budget - I am passing a value and that value is being set in the project, however the Budget field is disabled. When I create a new project from the Kantata UI, the field remains enabled, so it confirms I do have the appropriate permissions in Kantata. My project permissions are also set correctly to Project Admin. Schedule and budget changes must be approved - even though I am telling it to not have this  option checked, it still creates the project with this option checked Target margin - I am sending in a value b

I tried to use Zapier webhook(gmail connected) to send a mail as usual but to day i encountered a new error saying “Invalid proxy server token passed” where i thought the problem was on my side(my code) and then tried it on Cursor AI by connecting the server config from zapier then encountered the same error where the agent is returning this response from zapier:{  "error": "Authentication Error, Invalid proxy server token passed. Received API Key = sk-...OiKQ, Key Hash (Token) =XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX. Unable to find token in cache or `LiteLLM_VerificationTokenTable`"}The agents on Cursor AI are also encountering error to execute a  gmail_send_email toolFor reference i have also uploaded the screenshot of the error on Cursor AI and Zapier historyHow to solve this issue?Is this problem associated with the Cursor agents or Zapier! 

I’m embedding Zapier MCP inside an Android WebView (Jetpack Compose).The integration works sometimes, but intermittently the embed shows a blank screen — even though the console says ✅ mcp.js manually loaded.@Composablefun ZapierWebView(viewModel: ZapierViewModel) {    AndroidView(factory = { context ->        WebView(context).apply {            WebView.setWebContentsDebuggingEnabled(true)            settings.javaScriptEnabled = true            settings.domStorageEnabled = true            settings.mixedContentMode = WebSettings.MIXED_CONTENT_ALWAYS_ALLOW            CookieManager.getInstance().setAcceptThirdPartyCookies(this, true)            addJavascriptInterface(object {                @JavascriptInterface                fun onServerUrlReceived(url: String) {                    Log.d("ZapierJS", "✅ MCP Server URL received: $url")

I connected the Google Ads MCP (Multi-Client Platform) to Claude, but discovered a key limitation in how it handles account selection.Unlike the Google Analytics MCP integration which allows you to choose which account to connect (for example, a management account or a specific property) the Google Ads MCP does not currently provide an option to select or switch between accounts. Once connected, it automatically links to the primary Google Ads account associated with the authenticated email address.This poses a challenge for agencies and consultants who manage multiple client accounts under a single Google Ads manager login. Without the ability to search for, select, or switch between linked accounts, you’re effectively restricted to data from the default account only.In practice, this means that anyone managing several businesses, campaigns, or client accounts from one email address cannot easily access or query the individual account data through Claude. Each

After the successful, OAuth2.0 AuthorizationCodeGrantFlow and fetching the access token. When connecting to zapier mcp server, I am getting data: {"jsonrpc":"2.0","id":0,"error":{"code":-32001,"message":"Error POSTing to endpoint (HTTP 401): {\"jsonrpc\":\"2.0\",\"id\":null,\"error\":{\"code\":-32600,\"message\":\"Invalid authorization: Failed to decode server ID and secret from token\"}}","data":{}}}

Hi All, I’ve tried to use AI Actions in ChatGPT and it starts to work. Only problem is that every action need to be confirmed by clicking button, which makes all this stuff little unproductive. Did I configured something wrong? 

Here is the URL where we have created an Anthropic API based MCP Server that connects to our Confluence Cloud.https://mcp.zapier.com/mcp/servers/XXXXXXXXXXXXXXXXXXXXXXXXXX/connectionsConfluence Cloud Site - https://.atlassian.net/wiki/spaces.atlassian.net/wiki/When I send a query to write to a space in this site, I get a response which tells me that the confluence page has been created but the URL to access this page is not available due to permission issues. However, in reality the page is never created at that location.Attached are some screenshots of tools access testing and the query I ran using some python code and the Anthropic Client.  query = "Create a new Confluence page with content: \"This project focuses on developing an intelligent chatbot application designed to enhance custom

Hello Team, I am using Open AI agent SDK to send automated mail through Zapier MCP. When i configured the below config in claude desktop , it is working but the same is not working from python client. It is giving timeout error. Can you please help where to properliy increase timeout config. params={            "command": "npx",            "args": [                "--yes",  # Auto-accept npm package installation                "mcp-remote",                "URL with key"            ],            "env": {                "NODE_OPTIONS": "--max-old-space-size=4096",                # Add environment variables to bypass prompts                "CI": "true",  # Indicates automated environment                "ZAPIER_MCP_AUTO_APPROVE": "true",  # If supported by Zapier                "NO_PROMPT": "true",                "ZAPIER_MCP_TIMEOUT": "10000"  # Set timeout to 10 seconds

I’ve tried numerous suggestions to fix this, disconnecting and reconnecting the OpenAI connection with Zapier’s AI Actions, but for some reason GPT is unable to gather or list any of the available actions that I created in Zapier’s API Actions. I don’t understand why this keeps on happening. Everyting’s connected, the action is enabled, but for some reason Zapier’s API fails to return a response. It sometimes work when I preview it. I then update it and then try to actually use the AI action in GPT, but it always fails to connect. Is the API flawed here, what gives?

Hello! I’m trying to better understand the function of AI withing a zap. When using AI by Zapier, can you reference a Table (Zapier) and perform a lookup function in one column and return a result from another column. For example:AI analyzes the information and returns the house title “Fantastic home near parks and dining”.The specific address of the house is needed and the title is used to look up the street address.Can AI then reference a table in Zapier and Title column to look up “Fantastic home near parks and dining” and return to me the actual street address listing in another column?….. “1234 Main St Anytown, AK 54321” Is this possible or do I need to perform the look-up and return function in another task in the zap?

Hello, I’m trying to implement AI Actions on my SaaS platform. I’m trying to generate Oauth Login Link and it’s asking me for AI Actions OAUTH Client. Can anyone tell me where I can create this client and/or how this works?

I am trying to connect my zapier MCP server to Google Analytics 4. I am able to connect to the account correctly. But when testing the action Run Report for a Property , it is redirecting me to the modal where it is asking for the query again. I can see the error in console as Bad request and unable to emit event, see attached image. This post has been edited by a moderator to remove potentially sensitive details.

Hi, the Zapier AI Actions are working on my ChatGPT web (Chrome). I have actions such as add to my calendar etc. However, on the ChatGPT android app, I get error “I can’t access the calendar tool at the moment. This is the same for all other actions as well. I have tried deleteing and reinstalling the chatgpt app. Loging in and out. Is there any solution to this?

I am facing an error while trying to use Zapier MCP server to integrate with application - Razorpay. I am able to successfully link Razorpay account, but when I trying to enable all tools in the MCP server, it is not going to next screen.I am stuck in below screen, need some help 

Hi,I was interested in Zapier’s MCP and had a look at the following youtube video - https://youtu.be/QEShi98TCaU?si=9WcTK4SnMfONyAiR -  where the developer shows how to use Zapier MCP to connect to VAPI’s AI Voice Assistant, I followed the video to the letter ‘t’ (except copy his prompts, but, the important once were copied) but could not sent even one SMS.This is what I get from the call log{ "role": "tool_calls", "time": 1748618189819, "message": "", "toolCalls": [ { "id": "call_DNwH6A7UxXINoWwlcIApDKjr", "type": "function", "function": { "name": "mcp_tool", "arguments": "{}" } }, { "id": "call_PCMnea2spYJ7bHp1U0CglJOr", "type": "function", "function": { "name": "mcp_t

The Anthropic API has options to enable ‘thinking’ in its newest models (Sonnet 3.7, Sonnet 4 and Opus 4). As far as I can see, there’s no option to enable this in Zapier, so currently all the requests to the new models are not doing any thinking. Anthropic docs for this are here: https://docs.anthropic.com/en/docs/build-with-claude/extended-thinking#how-extended-thinking-worksWould be great to have this as an option (and also to have the thinking tokens/summaries as a variable we can work with too), as it unlocks the higher levels of capability (there are some Zaps I have that will only work with Opus thinking atm).   

Besides the obvious UI difference, what are the differences in using AI by Zapier Claude or ChatGPT models vs using Claude and ChatGPT’s standalone Zapier actions?

I’m having trouble with oAuth with my Claude Desktop to the Zapier MCP server.  When I launch Claude Desktop, it redirects me to an oAUTH page for Zapier but I get an error: Error: invalid_requestMismatching redirect URI. Below is my JSON Configuration file for Claude Desktop:{  "mcpServers": {    "zapier-mcp": {      "command": "npx",      "args": [        "mcp-remote",        "https://mcp.zapier.com/api/mcp/a/16048681/sse"      ]    },    "github": {      "command": "npx",      "args": [        "-y",        "@modelcontextprotocol/server-github"      ],      "env": {        "GITHUB_PERSONAL_ACCESS_TOKEN": "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"      }    }  },  "globalShortcut": "Ctrl+Space"}

Hey! I”m trying to create an automation that goes from (simplified but you get the idea) Airtable new row → Prompts SOMETHING to do some research → AI writes summary → adds summary to Airtable. It doesn’t seem ChatGPT is connecting to the internet to search for up-to-date info. Will Claude do this? Is this where I need perplexity?

I’m logged into Zapier. I went to https://zapier.com/mcp to try out MCP. I then hit the the button “Get started” and it opens up a net tab to https://mcp.zapier.com/mcp. That page gives me a 500 error. Please advise as I don’t know what or how to proceed. I really want to test this out.  

Is possible to get the token usage from AI action by AI Zapier? I want to prompt the AI Action and try to see how much tokens was being used for this action.
