Reddit Ads

The film shows hosted getmcpads with sample data. Its MCP Apps, from creative galleries and alerts to Google Sheets exports and bulk launches, belong to the hosted product. This repository provides the standalone native API tools.

31 read tools · 22 write tools, disabled by default.

Run locally with your own platform credentials and a client that supports stdio MCP, such as Claude Desktop, Claude Code or Cursor. Your requests go directly to the platform. For managed connections, including supported ChatGPT setups, use the hosted option.

What's new

v1.0.1: Zod 4 security update · October 26, 2026

• Update zod to 4.6.7. Every Zod release before 4.6.6 is covered by the high-severity advisory GHSA-mrhx-c7xc-m3w5: validating an oversized constrained collection can exhaust memory, and no Zod 3 release carries the fix. npm audit --omit=dev reports no vulnerability again.
• Keep the Zod 3 validation behaviour. A parameter default is still validated and completed before use, so an omitted object must still supply its required fields.
• Keep each parameter's own description when the parameter is optional or has a default. Zod 4 stores a description on the wrapped schema only, so the shared fallback description could otherwise replace it.
• reddit_get_insights still names the rejected value when a metric or breakdown is unknown.
• Tool names, parameters and descriptions published over MCP are unchanged. server-card.json is regenerated with Zod 4's JSON Schema output, which spells some constraints differently.

Upgrade notes

Requires Node.js 22.23.4, 24.22.1, 26.12.1 or a newer release of those lines. CI covers Node 22, 24 and 26, and the server prints a warning to stderr on an older runtime. Writes remain optional and require explicit confirmation. Hosted creative integrations and MCP Apps UI are outside this release.

Install this release

This is a GitHub source release. npm and MCP Registry versions are published separately. The commands below select this exact version; unpinned npx examples later in this document select the version currently available on npm.

git clone --branch v1.0.1 --depth 1 https://github.com/get-mcp-ads/reddit-ads-mcp-server.gitcd reddit-ads-mcp-servernpm cinpm run build

Configure your MCP client to run node with the absolute path to dist/cli.js and the platform credentials documented below. Once the package is on npm, the same server runs with npx -y @getmcpads/reddit-ads-mcp-server. A Claude Desktop entry looks like this:

{  "mcpServers": {    "reddit-ads": {      "command": "npx",      "args": ["-y", "@getmcpads/reddit-ads-mcp-server"],      "env": {        "REDDIT_ADS_REFRESH_TOKEN": "your-refresh-token",        "REDDIT_ADS_CLIENT_ID": "your-app-client-id",        "REDDIT_ADS_CLIENT_SECRET": "your-app-secret",        "REDDIT_ADS_ACCOUNT_IDS": "a2_abc123"      }    }  }}

Managed connection. Use Reddit Ads with hosted getmcpads. Connect your account, select the data your assistant may access and use the hosted MCP connection. See the site for current features and plans.

Configuration

Provide these environment variables through the client's secret configuration:

Register a developer application and request Ads API access as described in Reddit's Ads API documentation. Then run Reddit's OAuth authorization code flow with the scopes adsread, plus adsedit only if you plan to enable writes, and duration=permanent to receive a refresh token. Reddit access tokens expire after about an hour. Give the refresh token and the app credentials for daily use; an access token alone works until it expires. This package accepts tokens. It does not run an OAuth browser flow and never writes a renewed token to disk. Reddit ad account IDs start with a2_; the business ID is a different value.

npm run doctor reports which variables are set, without printing any value, and whether your Node.js release carries the October 2026 security fixes. Run reddit_health_check as the first call: it reads the account, its business, currency and timezone.

Safety and coverage

Writes preview by default. Review the exact account, target and payload before repeating the call with confirm: true. Campaigns, ad groups and ads are created paused. Activation can spend advertising budget, and previews that set configured_status to ACTIVE say so with activationMaySpend. Do not retry a write automatically when its result is uncertain. Read the account and reconcile it first. The server retries only after an HTTP 401, once, when it renewed the token, because Reddit rejected that request before acting on it. The account allowlist applies before every request. Each entity read is checked against the ad account, directly or through its profile, business or catalog. Before a confirmed write, the campaigns, ad groups, posts, audiences, pixels, product sets, profiles and assets it references are checked the same way. Write payloads are validated against Reddit's schemas pinned on 2026-09-11. Billing fields and computed statuses are refused. Passing local validation is not provider acceptance. Budgets, bids and SPEND are microcurrency: one millionth of the account currency. Other reporting fields keep their native units. Pagination cursors are Reddit's own page tokens.

Requests go only to ads-api.reddit.com and, for token renewal, www.reddit.com. No request follows a redirect. Each one has a timeout and a response size limit. Credentials are redacted from every result and error. Media URLs that Reddit returns are passed on as data. This server never downloads them.

Some Reddit capabilities are intentionally not exposed:

• Customer-list member uploads and conversion event injection.
• Lead submissions and any other download of personal records. Lead forms are readable as configuration only.
• Product feeds, billing and funding instruments.
• Destructive deletes. Status updates accept PAUSED and ACTIVE only, and saved audiences cannot be set to DELETED.
• Onsite lead-form creation, which Reddit ended on September 21, 2026.

This server exposes a reviewed subset of the Reddit Ads API. It does not automatically expose new upstream endpoints. Hosted creative galleries, alerts, exports and MCP Apps UI are excluded. Use tools/list or server-card.json for exact schemas, reddit_get_write_schema for the pinned write schemas and Reddit's API reference for provider details.
