Submitator

Submitator MCP server

Launch your clients' products on up to 100 directories each from Claude, ChatGPT, Cursor or VS Code.

This MCP server is for agencies on Submitator's white label plan. Your assistant creates a client project from a URL, shows which directories it would reach, launches it once you agree, and follows the listings as they go live. The badge, the report and the client page carry your agency's brand. It calls the Submitator API with your agency key and does nothing the API does not.

What you need

• An agency account: app.submitator.com/agency/start.
• An API key from Developers in the agency console. With claude.ai or ChatGPT, the sign-in creates one (see Remote server).
• A sbm_test_ key is free from the day you create the agency. It runs in test mode: projects and listings are test data, nothing is submitted, and its test launches are not bought ones.
• A sbm_live_ key comes with your first purchase. Each launch_project spends one launch.

Install

The package runs on your machine with npx (Node.js 20 or newer). Keep the key in your user-level config, never in a file that lives in a repository.

Claude Code (user scope, so the key stays out of the project's .mcp.json)

claude mcp add --scope user submitator --env SUBMITATOR_API_KEY=sbm_test_... -- npx -y submitator-mcp

Cursor (~/.cursor/mcp.json, the user-level file)

{

"mcpServers": { "submitator": { "command": "npx", "args": ["-y", "submitator-mcp"], "env": { "SUBMITATOR_API_KEY": "sbm_test_..." } } } }

VS Code (.vscode/mcp.json): VS Code asks for the key and keeps it out of the file.

{

"inputs": [ { "type": "promptString", "id": "submitator-key", "description": "Submitator API key", "password": true } ], "servers": { "submitator": { "type": "stdio", "command": "npx", "args": ["-y", "submitator-mcp"], "env": { "SUBMITATOR_API_KEY": "${input:submitator-key}" } } } }

Claude Desktop (claude_desktop_config.json): the same block as Cursor, under mcpServers. Claude Desktop starts servers in the disk root, so add "SUBMITATOR_FILES_DIR": "/path/to/client/images" to env if you want to upload local images.

Devin Desktop (formerly Windsurf), Cline and other MCP clients: run npx -y submitator-mcp with SUBMITATOR_API_KEY in its environment, or use the remote server below.

Remote server

The remote server at https://mcp.submitator.com/mcp needs no install. There are two ways in: claude.ai and ChatGPT sign in to Submitator, and other clients send an agency key in a header.

claude.ai: sign in

1. In claude.ai, open Customize > Connectors, press + Add, then Add custom connector.
2. Enter the name Submitator and the URL https://mcp.submitator.com/mcp, then press Continue. Check the settings it found and press Continue again.
3. Under Authentication pick Sign in now, keep Use Claude's published identity (Recommended) as the OAuth client, leave Request headers empty and press Add.
4. Submitator's sign-in opens: log in to the agency console. The consent page names the client and its host (Claude, claude.ai). Pick Test or Live and Full or Read only, then press Allow Claude.
5. In a chat, open +, then Connectors, and switch Submitator on.

This link opens the dialog of step 1 with the name and the URL filled in.

The sign-in creates a key labelled MCP: Claude on the console's Developers page. Revoke it there to disconnect: the next call asks to sign in again. Live needs an agency that has bought launches, so a new agency gets Test only, and test mode submits nothing.

On Team and Enterprise plans an Owner adds the connector first, under Organization settings > Connectors: Add, Custom, Web. Members then press Connect under Customize > Connectors, and each of them signs in.

ChatGPT: sign in

1. In ChatGPT on the web, open Plugins (chatgpt.com/plugins), press the plus button, then Add custom MCP server.
2. Enter the name Submitator and, under Connection, the Server URL https://mcp.submitator.com/mcp.
3. For authentication pick OAuth with a Client ID Metadata Document (CIMD), and enter no client ID or secret: Submitator's sign-in reads ChatGPT's published client document and needs no client registration.
4. Review the risk warning, select I understand and want to continue, then Create as a plugin.
5. Install the plugin, then in a chat type @ and pick it.

When ChatGPT sends you to Submitator's sign-in, log in to the agency console, pick Test or Live and Full or Read only on the consent page, and allow ChatGPT. As with claude.ai, the sign-in creates a key whose label starts with MCP: on the console's Developers page (revoke it there to disconnect), and a new agency gets Test only.

OpenAI's documentation says ChatGPT asks for confirmation before write actions by default and treats a tool without readOnlyHint as a write. Here the tools that only read carry readOnlyHint: true, and every other tool false. In a workspace, its permissions and security settings apply to adding and using custom MCP servers.

Claude Code, Cursor, VS Code and other clients: a key in a header

URL:    https://mcp.submitator.com/mcp

Header: Authorization: Bearer (X-API-Key: works too)

Claude Code

claude mcp add --transport http submitator https://mcp.submitator.com/mcp \

--header "Authorization: Bearer $SUBMITATOR_API_KEY"

Cursor (~/.cursor/mcp.json)

{

"mcpServers": { "submitator": { "url": "https://mcp.submitator.com/mcp", "headers": { "Authorization": "Bearer sbm_test_..." } } } }

VS Code (.vscode/mcp.json): VS Code asks for the key and keeps it out of the file.

{

"inputs": [ { "type": "promptString", "id": "submitator-key", "description": "Submitator API key", "password": true } ], "servers": { "submitator": { "type": "http", "url": "https://mcp.submitator.com/mcp", "headers": { "Authorization": "Bearer ${input:submitator-key}" } } } }

Other clients that connect over HTTP take the same URL and header.

The remote server keeps nothing between requests: it passes the key, from the header or from the sign-in's access token, on to the Submitator API and forgets it. Files cannot be read or saved there, so save_report_file and local image paths work only with the npx package.

Tools

Prompts: launch_client_project walks through a launch, and client_progress_update drafts a note for your client that does not name Submitator.

Keys and safety

• Keep your client's approval prompt on for launch_project, add_directories and update_project instead of allowing them always: a launch spends money. These three, like every tool that overwrites or deletes data or submits to directories, carry destructiveHint: true, so clients that read the hint ask before each call. Tools that only add or check, such as create_project, add_screenshot and verify_badge, carry false. With a live key, clients that support questions to their user (MCP elicitation) also ask you before a launch or an add, and the answer never passes through the model. The remote server keeps no session, so there this question reaches only clients on MCP protocol 2026-07-28.
• The npx package reads the key from its environment and sends it only to https://api.submitator.com.
• Local images are read only from SUBMITATOR_FILES_DIR (or the folder the client starts the server in), only real PNG, JPEG, GIF or WebP files, and never through a link. Reports are saved to Downloads by default and never over an existing file; reports that include logins are not saved here.
• A read-only key fits an assistant that only checks status: projects, listings, events and existing reports. Building a report or a client page link needs a key with full permissions.
• Logins and their passwords are not exposed through this server. Read them in the agency console.
• Every call shows up in Developers, Request log with a request id that starts with mcp-. Revoke a key there at any time.
• Report a vulnerability by email to vlad@submitator.com, not in a public issue (SECURITY.md).

Development

npm install

npm test # unit, contract and protocol tests npm run build npm run sync:openapi # refresh openapi/v1.json and src/v1.d.ts from the public contract npm run check:pack # pack, install in an empty folder, run the stdio handshake

When the API ships a new release, npm run sync:openapi and npm test show which new operations need a tool or a line in EXCLUDED (src/tools/index.ts).
