🪄 fix: MCP UI Renders for OAuth and Custom User Vars Servers

[dustinhealy]

Summary

This pull request changes the behavior of the MCP UI elements in chat so that they will now always appear if there are any MCP servers configured in librechat.yaml that do not have chatMenu set to false in order to address the issue raised in [Enhancement]: Stop hiding MCP Servers badge when all servers are "oauth" or "customUserVars"

Previously, startup: false and OAuth servers would not cause the MCP UI to render on their own, requiring users to initialize them in the MCP Settings Panel before the badge / tools dropdown would appear. In order to accomplish this change, the mcpServerNames property has been removed from the context in favor of using the more comprehensive mcpServerManager, which provides access to configuredServers directly. This has the added benefit of streamlining server configuration checks and improving maintainability.

Context refactoring:

• Removed the mcpServerNames property and its associated logic from BadgeRowContext.tsx, replacing it with mcpServerManager for more robust server configuration handling. [1] [2] [3] [4]

Component updates for server configuration:

• Updated MCPSelect.tsx and ToolsDropdown.tsx components to use configuredServers from mcpServerManager instead of relying on mcpServerNames, ensuring consistent server availability checks and rendering logic. [1] [2] [3]

• Simplified conditional rendering in MCPSelectContent by removing checks for isPinned and mcpValues, relying solely on configuredServers for display logic. [1] [2]

Change Type

• Bug fix (non-breaking change which fixes an issue)

Testing

Verified absence of MCPSelect and ToolsDropdown when only github-mcp with startup: false or spotify mcp server (OAuth) configured in YAML

Verified presence of aforementioned elements with same YAML configuration after changes
