Swagger MCP Bridge

Swagger MCP Bridge is a small add-on for web apps built with Spring Boot, a popular way to build Java apps. It takes the list of actions your app already publishes about itself and turns them into tools your AI assistant can call. It is handy for developers and small teams who want an AI to work with an app they already have, without writing new code for every action.

What this MCP server does

You add this add-on to an existing Spring Boot app and switch it on. From then on, the app reads its own published description of available actions and offers each one to your AI as a tool. When you ask your AI something, it picks the matching action, fills in the details, and the helper sends the request to your app. You get the answer back in the chat, and if something is missing or risky, it tells you before doing anything. There are also helper tools that let the AI look around first, plan a few steps, and test a call before running it for real.

What you can do with it

• Ask your AI what actions your app offers and how they are grouped
• Describe a single action so you can see what it needs before running it
• Let your AI pick the right action from a plain-English request
• Check a call for missing details without actually running it
• Plan a chain of steps, such as creating a record and then reading it back
• Run a plan as a dry run first, then for real when it looks clean
• Keep risky actions behind a confirmation word you set

Try asking your AI

• “What actions does my app offer, grouped by area?”
• “Describe the get order action and show me the details it needs.”
• “Check this call before running it: get order with id order-1.”
• “Plan a workflow that creates an order and then reads it back.”

What it gives back to you

You get answers in the chat, in everyday words: what actions exist, what a particular action needs, and whether a planned call looks complete. When a call runs for real, you see what your app sent back, such as the data you asked for or a note that a record was created. If a call is refused, you get a short, clear explanation, for example that a required detail was missing, instead of a broken request being sent.
