I have a few updates to my MCP server I wanna share: New Memory tool, improvements to web search & speech generation.
# Memory_Manager Tool
We now have a Memory_Manager tool. Ask ChatGPT to write all its memories verbatim, then tell gpt-oss-20b to save each one using the tool, then take them anywhere! It stores memories in a
The Memory_Manager tool is currently hidden from the HF space because it's intended for local use. It's enabled by providing a HF_READ_TOKEN in the env secrets, although it doesn't actually use the key for anything. There's probably a cleaner way of ensuring memory is only used locally, I'll come back to this.
# Fetch & Websearch
The Fetch_Webpage tool has been simplified a lot. It now converts the page to Markdown and returns the page with three length settings (Brief, Standard, Full). This is a lot more reliable than the old custom extraction method.
The Search_DuckDuckGo tool has a few small improvements. The input is easier for small models to get right, and the output is more readable.
# Speech Generation
I've added the remaining voices for Kokoro-82M, it now supports all 54 voices with all accents/languages.
I also removed the 30 second cap by making sure it computes all chunks in sequence, not just the first. I've tested it on outputs that are ~10 minutes long. Do note that when used as an MCP server, the tool will timeout after 1 minute, nothing I can do about that for right now.
# Other Thoughts
Lots of MCP use cases involve manipulating media (image editing, ASR, etc.). I've avoided adding tools like this so far for two reasons:
1. Most of these solutions would require assigning it a ZeroGPU slot.
2. The current process of uploading files like images to a Gradio space is still a bit rough. It's doable but requires additional tools.
Both of these points make it a bit painful for local usage. I'm open to suggestions for other tools that rely on text.
