[P1] Metrics Collector Failing - MCP Gateway Schema Validation Error

[github-actions]

🚨 High Priority: Metrics Collector Workflow Failing

Summary

The Metrics Collector workflow has degraded to 50% success rate (5/10 runs) starting January 9, 2026. This is blocking all workflow health monitoring and metrics collection.

Error Details

• Error Type: MCP Gateway configuration validation error
• MCP Gateway Version: v0.0.47
• Success Rate: 50% (was 100% before 2026-01-09)
• Last Success: Run Add HTTP transport capability validation and time MCP server for agentic engines #19 (2026-01-08)
• Impact: No workflow metrics collected for 5+ days

Root Cause

MCP Gateway schema breaking change in v0.0.47 requires:

• New container property for stdio server config
• Removal of command property (now invalid)
• Updated configuration structure

Error Messages

Error: failed to load config: Configuration validation error (MCP Gateway version: v0.0.47):

Sample Failed Run

• Date: 2026-01-13
• Run Number: #24

Required Fix

Update MCP Server Configuration

The workflow needs to migrate from old schema:

tools:
  server_name:
    command: "/path/to/server"
    args: ["--arg1"]
    env:
      VAR: "value"

To new schema:

tools:
  server_name:
    container:
      image: "server-image:latest"
      # or for stdio mode
      # command: "/path/to/server"
      # args: ["--arg1"]
    env:
      VAR: "value"

Recommended Actions

Immediate (P1)

1. Review Workflow File: .github/workflows/metrics-collector.md
2. Update MCP Configuration: Migrate to new schema format
3. Test with MCP Gateway v0.0.47: Validate configuration
4. Recompile Workflow: Run make recompile after changes

Follow-up

1. Audit all workflows for MCP Gateway usage
2. Document schema migration guide
3. Add schema validation to CI/CD
4. Consider pinning MCP Gateway version

Impact Assessment

Direct Impact

• No workflow metrics since 2026-01-09
• Workflow Health Manager lacks execution data
• Agent Performance Analyzer missing metrics
• Unable to track success rates, failures, performance

Cascade Impact

• Meta-orchestrator monitoring degraded
• System health visibility lost
• Other orchestrators (Campaign Manager) affected
• Cannot detect new failures or trends

Related Issues

• Part of MCP Gateway breaking change affecting multiple workflows
• Meta-orchestrator cascade failure
• Highest priority for system visibility restoration
