[language-support] Serena MCP tools unavailable — Go, TypeScript/JavaScript, and Python language support tests failed

[github-actions]

Summary

The language support tester workflow ran on 2026-02-23 and was unable to test Go, TypeScript/JavaScript, or Python language support because Serena MCP tools (serena-* prefix) are not available in the agent environment.

Languages Affected

• ❌ Go — serena-get_symbols_overview and serena-find_symbol not available
• ❌ TypeScript/JavaScript — serena-get_symbols_overview and serena-find_symbol not available
• ❌ Python — serena-get_symbols_overview and serena-find_symbol not available

Specific Errors

When attempting to call Serena MCP tools in the agent session, none of the serena-* prefixed tools were registered in the toolset. The complete available toolset consisted only of bash, view, edit, grep, glob, sql, github-, and safeoutputs- tools — no serena-* tools were present.

Steps to Reproduce

1. Trigger the language-support-tester workflow (workflow run ID: 22292708646)
2. The agent attempts to call serena-get_symbols_overview and serena-find_symbol
3. Tools are not found/registered — all calls fail

Possible Root Causes

1. The Serena MCP server is not running or failed to start in the workflow environment
2. The MCP gateway is not configured with a serena server entry, or the entry is misconfigured
3. The tool-registration handshake between the MCP gateway and Serena backend failed
4. The Serena MCP server is not connected to the agent's session

Diagnostics to Check

• Confirm the serena process is active in the workflow runner
• Check config.toml / awmg-config.json for a serena server entry
• Check mcp-gateway.log for Serena backend startup errors
• Check tools.json in the log directory to see if Serena tools were registered

Workflow Run

• Run ID: 22292708646
• Repository: github/gh-aw-mcpg
• Date: 2026-02-23
