removing a tool or resource dynamically #711
Description
Activity
Hi @skunkwerk,
I've submitted a PR that addresses this feature request: #728
The PR adds enable() and disable() methods to tools, which allows temporarily disabling tools and re-enabling them when needed.
Would this solution work for your use case?

I can't speak for @skunkwerk, but for our use case (a multi-tenant MCP server), no, we need to actually remove the tool, not just disable it.
Right now, we are doing some hackery like
def _remove_tool_from_mcp(self, tool_name: str) -> bool: """Remove a tool from the MCP server. NOTE: There is no API available for tool removal, so we edit private members ourselves. """ if tool_name in mcp._tool_manager._tools: # noqa: SLF001 del mcp._tool_manager._tools[tool_name] # noqa: SLF001 return True return False
- linked a pull request that will close this issuefeat: add ability to remove tools #1322
on Oct 3, 2025 Should be addressed by #1322 once we land that
- marked Dynamic load or unload mcp tools #599 as a duplicate of this issue

Is your feature request related to a problem? Please describe.
There doesn't seem to be a way to call remove_tool or remove_resource, such as in the tool manager
Describe the solution you'd like
If this is indeed the case, I'm happy to submit a PR to add those methods to the resource & tool managers in fastMCP
