Built on the Model Context Protocol (MCP) for Claude, ChatGPT, Cursor, and more

The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.

This connection provides 6 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.

Documentation knowledge bases are constantly out of date., Solved with Vinkius AI Gateway

Today, updating technical guides means logging into the documentation platform dashboard. You check one tab for analytics, another to see if a specific site folder was crawled, and yet another to generate new search credentials for your apps. It's manual clicking, copy-pasting API keys, and hoping nothing breaks.

With this MCP, you tell your agent what needs to happen—like 'Index the entire v2 API section.' The agent handles the complex multi-step process behind the scenes. You get an instant confirmation that the content is live, searchable, and ready for users.

Ask Fern: Instant Answers Across Domains

Before this MCP, if a user asked a question that touched on both billing policies and API usage, you had to manually route the query or write an FAQ covering both areas. This was slow and prone to conflicting information.

Now, using `post_chat_completion`, your agent can read across defined domains—say, 'billing' and 'API usage'—and synthesize one coherent answer immediately. It makes cross-domain support instant.

What your AI can actually do with this

This connector lets your agent manage the life cycle of technical documentation. Instead of manually running separate jobs to check if content is indexed or if a feature is working, you simply tell your AI client what you need done. You can trigger new crawling jobs to include updated guides or instantly get answers from specific sections using advanced chat completion.

Plus, it gives you insight into how users actually interact with the material by retrieving recent queries and providing secure access tokens for external applications. Because Vinkius hosts this MCP, your agent connects once and gains control over the entire documentation process, letting you manage everything from analytics to content publishing.

Questions you might have

How do I use the Fern MCP to make sure my new website content is searchable? +

You run the index_website tool through your agent, specifying the full URL you want indexed. The system handles triggering the crawl and updating the search index for AI access.

What data does get_recent_queries provide about my users? +

This tool pulls raw analytics showing a list of recent questions asked by your user base, allowing you to identify gaps in your documentation or confusing topics immediately.

Can I use the Fern MCP for secure application integration? +

Yes. You can execute get_jwt and get_search_key. These tools generate the necessary access tokens and Algolia keys needed to connect external applications securely.

How does post_chat_completion work with different knowledge sections? +

You simply instruct your agent via the tool prompt, specifying which documentation domains it should use. The assistant then synthesizes a single answer from all provided contexts.

Is whoami useful for verifying my API client's status? +

Yes. Running whoami checks your current authentication status and user details, which is useful for building internal workflows that require identity validation before running other tools.
