Building MCP Servers with ToolGroups and OSGi Services
MCP Server development has become popular, and developers are frequently looking to build MCP Servers, and expose existing APIs and services as MCP Tools.
The ECF Project has recently added support for Dynamic Tool Groups based upon and extending the mcp-annotations project. Although not limited to OSGi frameworks, the ability to dynamically reflect and generate MCP Tool Specification Metadata from mcp annotated OSGi services makes it an excellent fit for the OSGi Service Registry and the Service Component Runtime.
We’ve recently added 3 new bndtools project templates for constructing and testing MCP Servers. These MCP Servers, can dynamically add or remove any mcp annotated OSGi service as an MCP Tool Group (set of associated tools), making it immediately available to any MCP Client for tool introspection or tool calling.
Below is a few screenshots showing the use of the 3 new project templates in bndtools to create an MCP ToolGroup OSGi service, dynamically add and remove the tools in that tool group to MCP sync or async server, and a simple example test client that to test the functioning of the MCP servers.
With Bndtoools 7.1+ installed an a recent version of Eclipse (4.36+), create a new Eclipse workspace and choose New->Bnd OSGi Workspace.
- Create a new Bndtools Workspace using the ECF Bndtools Workspace Template
- Create a new bndtools project using the ArithmeticToolGroup API Project template
The new project wizard will request a name for the project. You should use a name with java package-like ‘dot’ notation for the project name…e.g.: my.arithmetic.api
- Create a MCP Server project using the ArithmeticToolGroup MCP Servers Project template from the New Bnd OSGi Project wizard as shown above.
The project name should be unique, but should have same dot notation as above. For example: my.arithmetic.mcpserver
After the new project name entry and Next> this dialog will appear:
The name given during api project creation should be provided in this field as shown in the screenshot above.
- Create a MCP Test Client project using the ArithmeticToolGroup MCP Test Client Project template from the New Bnd OSGi Project wizard.
As before, you should give a project name like the two previous projects: my.arithmetic.mcpclient
This dialog will then appear and you should complete both fields with the names for the projects used above and choose Finish
You should then have three projects in your workspace. You may examine the API class (ArithmeticToolGroup in API project) or API impl in the mcpserver project (ArithmeticToolGroupComponent) the two (sync and async) servers.
Run/Debug the ArithmeticToolGroup MCP Servers in Eclipse
To Run or Debug the ArithmeticToolGroup MCP Servers, to to the mcpserver project in your workspace and open the file mcpservers.bndrun. Once the bndrun editor is open you can launch (run or debug) by choosing the Run OSGi or Debug OSGi button in the upper right of the bndrun editor.
In the console you should then get debug output like this

Welcome to Apache Felix Gogo
g!
The debug output indicates that both async and sync mcp servers were created (see AsyncMcpToolGroupServerComponent and SyncMcpToolGroupServerComponent), and that the ArithmeticToolGroupComponent api implementation was created but the api was dynamically inspected, tool specifications created, and then added to the sync or async servers appropriately. See ArithmeticToolGroupComponent.activate() method.
Run/Debug the Test MCP Client in Eclipse
In your MCP client project in workspace, open the mcpclient.bndrun file and choose Run OSGi/Debug OSGI as desired. The MCP Test Client has both an async client (McpAsyncClientCompoent) and sync client (McpSyncClientComponent). Both of these client connect via the Unix Domain Socket Transport to the async or sync MCP server that should be already running, and then call some of the async/sync method calls via the MCP protocol.
