We built an MCP server for 1500+ Tools

Hey everyone, I’m one of the co-founders of ApyHub.

We recently built an MCP server that lets your agent use 1500+ tools from one connector.

The idea is pretty simple.

Instead of wiring an MCP server to one API, then another, then another, the agent can search the catalog, find the API it needs, see what it does, and call it.

ApyHub has 400+ services and 1,500+ endpoints across things like file conversion, OCR, data extraction, validation, geolocation, SEO, image processing, and AI.

So you can give an agent a fairly small set of tools and still have access to a much larger set of capabilities.

Some examples:

• convert a Word document to PDF
• extract text from a PDF
• OCR a scanned document
• extract text from a webpage
• compress a video
• generate a QR code
• validate an EU VAT number
• validate email DNS
• convert currencies
• parse a resume
• check SERP rankings
• generate speech from text

The useful part is that these can also be chained.

For example:

Take a scanned invoice → OCR it → extract the data → validate the VAT number → convert the currency → generate a PDF.

Or:

Extract a webpage → check readability → summarize it → check its search ranking.

You don't have to build those workflows ahead of time. The agent can compose the calls based on the task.

There is also curation.

Giving an agent 1,500 tools creates tool bloat and overwhelms the model with context.

Instead, you can select which endpoints an agent may use: a document agent might have 15–20 endpoints, while an enrichment agent uses a different set.

One other thing we cared about was credentials.

Normally, connecting an agent to ten vendors requires ten API keys stored somewhere in the agent’s environment or context. Those traces eventually appear in logs, observability tools, bug reports, etc.

With ApyHub, the agent uses one scoped key.

The MCP server is at:

And the catalog is here:

The thing I’m most interested in is what people actually try to make their agents do with the catalog. There are a lot of boring utilities in there already, but there are always going to be things we haven't covered yet.

If you have any questions, I’m happy to assist 🙂
