Polarion MCP Servers

This repository contains Model Context Protocol (MCP) server implementations for Polarion Application Lifecycle Management (ALM) integration.

MCP Tools are available for Polarion work items, including:

• get_text_for_workitems_by_id: Gets the main text content for specified WorkItem IDs.
• get_documents: Lists documents in the project, optionally filtered by title.
• get_documents_by_space_names: Lists documents within specified space names.
• get_space_names: Lists all available space names in the project.
• search_workitems_in_document: Searches for WorkItems within a document based on text criteria.
• get_configured_custom_fields: Retrieves the list of custom fields configured for a specific WorkItem type ID, based on the current project's settings.
• list_configured_workitem_types: Lists all WorkItem type IDs that have custom field configurations defined in the current project's settings.
• get_custom_fields_for_workitems: Retrieves specified custom field values for a given list of WorkItem IDs.

Projects

• PolarionRemoteMcpServer: SSE-based MCP server for server based installations
• PolarionMcpServer: Console-based MCP server for Polarion integration for local workstation installations

Running via Docker & Linux Server (Recommended)

1. From your Linux server, create a directory for your configuration and logs:

   mkdir -p /opt/polarion-mcp-server
   cd /opt/polarion-mcp-server

2. Pull the Docker image:

   docker pull peakflames/polarion-remote-mcp-server

3. Create a tailored /opt/polarion-mcp-server/appsettings.json file to your Polarion configuration:

   {
     "Logging": {
       "LogLevel": {
         "Default": "Information",
         "Microsoft.AspNetCore": "Warning"
       }
     },
     "AllowedHosts": "*",
     "PolarionProjects": [
          {
              "ProjectUrlAlias": "starlight", 
              "Default": true,
              "SessionConfig": { 
                  "ServerUrl": "https://polarion.int.mycompany.com/",
                  "Username": "shared_user_read_only",
                  "Password": "linear-Vietnam-FLIP-212824", 
                  "ProjectId": "Starlight_Main", 
                  "TimeoutSeconds": 60
              },
              "PolarionWorkItemTypes": [
                {
                  "id": "requirement",
                  "fields": ["custom_field_1", "priority", "severity"]
                },
                {
                  "id": "defect",
                  "fields": ["defect_type", "found_in_build"]
                }
              ]
          },
          {
              "ProjectUrlAlias": "octopus", 
              "Default": false,
              "SessionConfig": { 
                  "ServerUrl": "https://polarion.int.mycompany.com/",
                  "Username": "some_other_user",
                  "Password": "linear-Vietnam-FLIP-212824", 
                  "ProjectId": "octopus_gov", 
                  "TimeoutSeconds": 60
              }
          },
          {
              "ProjectUrlAlias": "grogu", 
              "Default": false,
              "SessionConfig": { 
                  "ServerUrl": "https://polarion-dev.int.mycompany.com/",
                  "Username": "vader",
                  "Password": "12345", 
                  "ProjectId": "grogu_boss", 
                  "TimeoutSeconds": 60
              }
          }
      ]
   }

4. Run the Docker container:

   docker run -d \
     --name polarion-mcp-server \
     -p 8080:8080 \
     -v appsettings.json:/app/appsettings.json \
     peakflames/polarion-remote-mcp-server

5. The server should now be running. MCP clients will connect using a URL specific to the desired project configuration alias: http://{{your-server-ip}}:8080/{ProjectUrlAlias}/sse.

6. 📢IMPORTANT - Do NOT run with replica instances of the server as the session connection will not be shared between replicas.

Configuration Options (appsettings.json)

The server uses a PolarionProjects array in appsettings.json to define one or more Polarion instance configurations. Each object in the array represents a distinct configuration accessible via a unique URL alias.

Top-Level Setting	Description
PolarionProjects	(Array) Contains one or more Polarion project configuration objects.

Each Project Configuration Object:

Setting	Description	Required	Default
ProjectUrlAlias	A unique string used in the connection URL (/{ProjectUrlAlias}/sse) to identify this configuration.	Yes	N/A
Default	(boolean) If true, this configuration is used if the client connects without specifying a ProjectUrlAlias. Only one entry can be true.	No	false
SessionConfig	(Object) Contains the specific connection details for this Polarion instance.	Yes	N/A
PolarionWorkItemTypes	(Array, Optional) Defines custom fields to retrieve for specific WorkItem types within this project. Each object in the array should have an id (string, WorkItem type ID) and fields (array of strings, custom field names).	No	Empty List

SessionConfig Object Details:

Setting	Description	Required	Default
ServerUrl	URL of the Polarion server (e.g., "https://polarion.example.com/")	Yes	N/A
Username	Polarion username with appropriate permissions.	Yes	N/A
Password	Password for the Polarion user. (Consider secure alternatives)	Yes	N/A
ProjectId	The actual ID of the Polarion project to interact with.	Yes	N/A
TimeoutSeconds	Connection timeout in seconds.	No	60

Note: It is strongly recommended to use more secure methods for storing credentials (like User Secrets, Azure Key Vault, etc.) rather than placing plain text passwords in appsettings.json.

Configuring MCP Clients

To configure Cline:

1. Open Cline's MCP settings UI
2. Click the "Remote Servers" tab
3. For each ProjectUrlAlias in your appsettings.json that the user wants to connect to:

{
  "mcpServers": {
    ...
    ...

    "Polarion Starling": {
      "autoApprove": [],
      "disabled": true,
      "timeout": 60,
      "url": "http://{{your-server-ip}}:8080/starlight/sse",
      "transportType": "sse"
    },
    "Polarion Octopus": {
      "autoApprove": [],
      "disabled": true,
      "timeout": 60,
      "url": "http://{{your-server-ip}}:8080/octopus/sse",
    "transportType": "sse"
    }
  ...
  ...
}

1. Repeat for each ProjectUrlAlias you want to connect to.

To configure Visual Studio Code:

Add the following configuration to your settings.json file:

"servers": {
    "polarion-starlight": { // Use a descriptive key
        "type": "sse",
        "url": "http://{{your-server-ip}}:8080/starlight/sse", // Replace with your alias
        "env": {}
    },
    "polarion-octopus": { 
        "type": "sse",
        "url": "http://{{your-server-ip}}:8080/octopus/sse", // Replace with your alias
        "env": {}
    }
    // Add entries for each ProjectUrlAlias
}

To Claude Desktop:

Claude Desktop currently doesn’t support SSE, but you can use a proxy with the following addition to the claude_desktop_config.json file:

{
  "mcpServers": {
    "polarion-remote": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "http://{{your-server-ip}}:8080/{ProjectUrlAlias}/sse" // Replace {ProjectUrlAlias}
      ]
    }
    // Add entries for each ProjectUrlAlias, potentially using different keys like "polarion-starlight"
  }
}
