Connect Google Ads to LibreChat with MCP

$1B+ ad revenue generated $500M+ managed Ex-Scandiweb paid media lead 630+ MCP tools

To connect Google Ads to LibreChat, add a paidsync entry to librechat.yaml with type streamable-http and the URL https://mcp.paidsync.ai/mcp, restart LibreChat and sign in from the composer. Your self-hosted chat can then run PaidSync.ai tools for Google Ads, Meta Ads and 12 other platforms.

What LibreChat Needs

LibreChat reads MCP servers from its librechat.yaml file. For a remote server with sign-in you need:

An mcpServers entry with type streamable-http and the PaidSync.ai URL.
A restart of LibreChat after you edit the file.
A PaidSync.ai login with Google Ads connected.

LibreChat's docs say OAuth is detected automatically for these servers, and users sign in the first time they use one.

How the Connection Works

Setting	Value
File	librechat.yaml
Type	streamable-http
URL	https://mcp.paidsync.ai/mcp
initTimeout	150000, to leave time for the first sign-in
Sign-in	Pick the server in the composer's + palette

LibreChat waits up to 10 minutes for the OAuth flow by default. You can set oauthPrompt to on_use to delay the sign-in until the agent first calls a tool.

How to Connect Google Ads to LibreChat in 5 Steps

Do these in order. The code box holds the exact setup from LibreChat MCP docs.

Connect Google Ads to PaidSync.ai

Edit librechat.yaml

Add the paidsync entry from the box below under mcpServers.

Restart LibreChat

The docs say a restart is needed before the connection is created.

Sign in

Select the paidsync server in the composer's + palette and sign in with your PaidSync.ai login.

Ask a question

Ask about your Google Ads account and check that a PaidSync.ai tool is called.

librechat.yaml

mcpServers:
  paidsync:
    type: 'streamable-http'
    initTimeout: 150000
    url: 'https://mcp.paidsync.ai/mcp'

How to Check the Connection

Ask LibreChat to list your accounts first. If it names your Google Ads account, the entry works.

"List my Google Ads accounts and set the one called Main as active."

Run this to confirm the connection.

"Run get_wasted_spend_report for the last 30 days and list the search terms with cost and no conversions."

Run this to confirm the connection.

How PaidSync.ai Protects You

Each user signs in. LibreChat asks every user to authorise for themselves.
Reports change nothing. The wasted spend and performance reports only read your account.
Sign-in for changes. Applying a Google Ads change needs the OAuth sign-in.
A change log. Applied changes are logged, on a best-effort basis, with a before-and-after result.

Setup follows the LibreChat MCP documentation, checked on 24 October 2026. Source: LibreChat MCP docs. Every Google Ads tool is on the Google Ads MCP server page, and the full list of clients is on Connect your ads.
