Instana MCP wrapper that fixes WatsonX Orchestrator parameter stringification

Instana Wrapper MCP Server

Wrapper MCP server that fixes WatsonX Orchestrator parameter stringification issues for Instana tools.

Problem

WatsonX Developer Edition stringifies dictionary parameters when calling MCP tools, but the official Instana MCP server expects native Python dictionaries. This wrapper parses the stringified parameters and calls the actual Instana MCP server with the correct format.

Solution

This wrapper provides 5 critical Instana tools with parameter parsing:

1. get_host_metrics - Get CPU, memory, disk metrics for a host
2. get_application_metrics - Get application performance metrics
3. get_incidents - Get critical incidents/alerts
4. get_issues - Get warnings and issues
5. get_changes - Get deployment and configuration changes

Installation

# Install from PyPI (after publishing)
pip install instana-wrapper-mcp-server

# Or install from local directory
cd instana-wrapper-mcp-server
pip install -e .

Usage with WatsonX Orchestrator

1. Import Toolkit

orchestrate toolkits import \
  --kind mcp \
  --name instana-wrapper \
  --description "Instana monitoring wrapper with parameter parsing" \
  --package "instana-wrapper-mcp-server" \
  --command "uvx instana-wrapper-mcp-server --transport stdio" \
  --tools "*" \
  --app-id instana

2. Add to Agent

In WatsonX UI:

1. Open your agent
2. Go to Tools section
3. Add instana-wrapper toolkit
4. Select the tools you need

3. Test

Ask your agent:

"Get CPU and memory metrics for host t3992-dev1-db-node01-par01-dev"
"Show me incidents for host t3992-dev1-db-node01-par01-dev"
"Get application metrics for PDWDBT"

Environment Variables

# Required - Instana API credentials

Tools

get_host_metrics

Get infrastructure metrics for a specific host.

Parameters:

• hostname (string): Hostname or IP address
• metrics (string): JSON array of metrics, e.g., ["cpu.used", "memory.used"]
• time_range (string, optional): Time range like "1h", "24h", default "1h"

Example:

{
  "hostname": "t3992-dev1-db-node01-par01-dev",
  "metrics": "[\"cpu.used\", \"memory.used\", \"disk.used\"]",
  "time_range": "1h"
}

get_application_metrics

Get application performance metrics.

Parameters:

• application_name (string): Application name

Example:

{
  "application_name": "PDWDBT",
  "metrics": "[\"calls\", \"latency\", \"errors\"]",
  "time_range": "24h"
}
