12/13/2025, 5:48 PMi am working on a project and using tool router ,
i am facing one issue when loading my own tools using mcp into it, the context window is becoming too large, does anyone knows how to put own tools in tool router and make it discover on its own at the time on run time instead of loading all tools?

12/17/2025, 10:02 AMHey Deep,
We've released the new version of tool-router. Here's the changelog: [link](https://docs.composio.dev/docs/changelog/2025/12/15) and the full docs: [link](https://docs.composio.dev/tool-router/overview)
We're currently testing custom MCP server support internally and would be happy to onboard you as an alpha user. Integration with tool-router is in progress and will take some time, but I'll ping you as soon as it's ready.
Could you share your email here?

12/22/2025, 5:42 AMHi Deep,
- You can use the standard toolkits listing API: [link](https://docs.composio.dev/rest-api/toolkits/get-toolkits). Currently we don't have a field to indicate a toolkit is custom, but plan to add something like
is_custom_toolkit
