MCP toolFilter allow list not applied correctly

[bugcy013]

The MCP proxy toolFilter configuration for the MCP server is not functioning as expected.

Even though the allow list explicitly includes tools such as jira_search, the proxy continues to ignore them during tool registration.

Only jira_get_issue is successfully added, while other allowed tools are incorrectly filtered out.

This prevents limiting tool exposure properly and breaks intended tool-scoping for integrations.

config:

"atlassian": {
  "command": "uvx",
  "args": [
    "mcp-atlassian"
  ],
  "options": {
    "toolFilter": {
      "mode": "allow",
      "list": [
        "confluence_search",
        "jira_get_issue",
        "jira_search"
      ]
    }
  }
}
