Investigation of smoke test run #22238913503 reveals the Serena MCP test failure is a false negative - the server operates correctly but the Copilot agent cannot discover its tools due to incorrect tool naming.

Root Cause

Serena MCP server initializes successfully:

  • Loads 40 tools, exposes 23 in 'codex' context (excludes create_text_file, read_file, execute_shell_command, prepare_for_new_conversation, replace_content)
  • Auto-configures project, detects Go as primary language (53.2%)
  • Registers in gateway alongside other MCP servers
  • Both activate_project and find_symbol are available in the exposed toolset

Agent reports tools unavailable without attempting invocation:

rpc safeoutputs→tools/call missing_tool
  reason: "The Serena MCP server tools (activate_project, find_symbol) are not available"

Issue: The smoke test referenced tools without the server name prefix (activate_project, find_symbol), but the Copilot agent framework expects the server-toolname pattern for proper tool discovery in routed mode.

Changes Made

Updated .github/workflows/smoke-copilot.md to use correct tool naming convention:

  • Changed activate_projectserena-activate_project
  • Changed find_symbolserena-find_symbol

This matches the naming pattern used by other MCP tools in the workflow (e.g., safeinputs-gh, safeinputs-make) where tools are prefixed with their MCP server name using hyphens.

Analysis

Confirmed Working:

  • Container launch: ghcr.io/github/serena-mcp-server:latest
  • Server initialization: v0.1.4, process id=1
  • Project configuration: /home/runner/work/gh-aw-mcpg/gh-aw-mcpg/.serena/project.yml
  • Gateway registration: Listed in startup logs with 6 total servers

Fixed Issue:

  • Tool naming now follows the server-toolname convention required by the agent framework for tool discoverability
  • Recompiled workflow lock file with gh-aw v0.47.4

Note: Playwright test failure (network timeout to github.com) is expected due to firewall constraints, not a code issue.

Updated the smoke test to use serena-activate_project and serena-find_symbol tool names, matching the naming pattern used by other MCP tools in the workflow (e.g., safeinputs-gh, safeinputs-make).

The tools are referenced with the server name prefix using hyphens, which should resolve the discoverability issue where the Copilot agent couldn't find the Serena tools.

Pull request overview

This pull request fixes a tool discovery issue in the smoke-copilot workflow where Serena MCP server tools were not being discovered due to incorrect naming conventions. The fix updates tool references to use the server-toolname pattern required by the MCP Gateway routed mode when multiple MCP servers are configured.

Changes:

  • Updated Serena tool names from unprefixed (activate_project, find_symbol) to server-prefixed format (serena-activate_project, serena-find_symbol)
  • Upgraded gh-aw version from v0.47.1 to v0.47.4 with associated lock file recompilation
  • Updated GitHub MCP Server from v0.30.3 to v0.31.0

  • The MCP_GATEWAY_DOCKER_COMMAND should reference ghcr.io/github/gh-aw-mcpg:latest instead of :v0.1.4. The workflow builds a local container tagged as :latest (line 340), and this command needs to use that locally built container. Using :v0.1.4 here will cause the workflow to use an older pinned version instead of the freshly built local version, defeating the purpose of the local build step.

The MCP Gateway container version should be :latest instead of :v0.1.4. The workflow builds a local container tagged as ghcr.io/github/gh-aw-mcpg:latest (line 340), but this download step references :v0.1.4, which means the locally built container won't be used. This is inconsistent with other workflows like language-support-tester.lock.yml which correctly use :latest throughout. The lock file needs to be recompiled with the correct version, or the source .md file may need adjustment.

This issue also appears on line 1349 of the same file.
