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": "*",
     "ApiConsumers": {
       "Consumers": {
         "my_app": {
           "Name": "My Application",
           "ApplicationKey": "your-secure-api-key-here",
           "Active": true,
           "AllowedScopes": ["polarion:read"],
           "Description": "API consumer for my application"
         }
       }
     },
     "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:

   1. Streamable HTTP Transport: http://{{your-server-ip}}:8080/{ProjectUrlAlias}.
   2. SSE Transport: http://{{your-server-ip}}:8080/{ProjectUrlAlias}/sse.

6. The server also provides:

   • REST API: http://{{your-server-ip}}:8080/polarion/rest/v1/projects/{ProjectId}/... (uses SessionConfig.ProjectId)
     • Note: REST API endpoints require API key authentication via X-API-Key header
   • API Documentation: http://{{your-server-ip}}:8080/scalar/v1 (includes authentication UI)
   • Health Check: http://{{your-server-ip}}:8080/api/health

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

Configuration Options

Configuration Files:

• appsettings.json - Base configuration for production/server deployments
• appsettings.Development.json - Overrides base settings for local development (gitignored, takes precedence in Development mode)
• .env - Optional environment variables (copy from .env.example), can set POLARION_DEFAULT_PROJECT

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.

API Key Authentication (REST API Only)

REST API endpoints require authentication via API key. Configure API consumers in the ApiConsumers section of appsettings.json:

Setting	Description	Required
ApiConsumers.Consumers	Dictionary of consumer configurations keyed by consumer ID	Yes
Name	Display name for the API consumer	Yes
ApplicationKey	The API key used for authentication	Yes
Active	Whether the consumer is allowed to authenticate	Yes
AllowedScopes	List of scopes (e.g., ["polarion:read"])	Yes
Description	Optional description of the consumer	No

Available Scopes:

• polarion:read - Read access to all REST API endpoints

Usage:

curl -H "X-API-Key: your-api-key" http://localhost:8080/polarion/rest/v1/projects/{projectId}/spaces

Note: MCP endpoints, health checks (/api/health, /api/version), and API documentation (/scalar/v1) do not require authentication.

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"
  }
}

Running Locally (stdio)

For local development or workstation use, you can run the stdio-based MCP server:

1. Download the appropriate executable for your platform from the releases page
2. Configure your MCP client to use the stdio transport with the executable path
