FAQ

Something else? Ask in the demo form.

What is an MCP connector?

An MCP connector is a server that exposes your product's API as tools AI assistants can call, using the open Model Context Protocol. Users connect it once in Claude, ChatGPT, Grok, Cursor or VS Code and can then work with your product from the chat.

How do I get my SaaS into Claude's connector directory?

Host a remote MCP server over HTTPS with Streamable HTTP and OAuth 2.0, annotate every tool, and publish a privacy policy and docs. Then submit it from a paid Claude account at claude.ai/directory/manage with a test account that has sample data. Anthropic reviews it and decides the listing; we prepare and file the submission with you.

How do I get into ChatGPT's app directory?

Verify your organization on the OpenAI Platform, test the MCP server in ChatGPT developer mode, then submit it in the plugin submission portal with test prompts, a reviewer account without MFA and your website, support, privacy and terms URLs. OpenAI reviews every submission.

Does it work in Grok?

Yes. Grok supports custom MCP connectors at grok.com/connectors, so your users can add it by URL. Grok's built-in catalog is curated by xAI, so a listing there isn't something anyone can promise.

How much does it cost to build an MCP server?

Toolbridge charges a fixed $4,500 for a production MCP server with OAuth, or $7,500 including Claude and ChatGPT directory submissions. Care plans start at $400 a month.

How long does it take?

10 business days from when we have API access, hosting and DNS. Directory review happens after that and its timing is set by each platform.

Do you guarantee a listing?

No. Approval is each platform's decision. We deliver submissions that pass their automated checks and handle one round of reviewer fixes.

Where does the code live?

In your GitHub and hosting accounts. You own it on final payment.

Is the demo really free?

Yes. We build it on your public API, never publish it, and delete it after 14 days.
