I added an MCP tool to upload markdown articles to read later on Lion Reader, and it’s becoming one of my most used tools in Claude Code. Whenever I want to learn something but don’t want to be distracted from my current task, I can have Claude write me something to read later[1]; and when I have it run experiments, it can write a report and upload it directly.
The really confusing thing is that Instapaper and Pocket’s MCP tools don’t seem to support directly uploads at all (just saving URLs). It just seems like a glaringly missing feature. Am I the only one who does this kind of thing, or do other people save to notes apps or Google Docs or something?
This post was inspired by a single session where Claude wrote me a post about pre-LayerNorm and why I should use it instead of post-LN, an explainer about post-training acronyms (SFT, RLHF, PPO, DPO) and how they apply to an idea I had, plus two reports on circuits in a toy model and the outcome of an architecture change.
Reading all of this at my computer in a terminal would have been annoying, and asking a separate claude.ai session would have required re-explaining the context.

Is there a length limit on the “urls” you save? Can you save a 60 kB “URL” which is a data:text/markdown;charset=utf-8,%23%20For%20Later%0A%0AThis%20is%20a%20markdown%20document.%20**This%20is%20bold**?
[Link to that “document” if you want to test](data:text/markdown;charset=utf-8,%23%20For%20Later%0A%0AThis%20is%20a%20markdown%20document.%20This%20is%20bold)

It’s on my todo list to see if sub-agents can do this, to avoid wasting context, but you can alway rewind after.

Instapaper claims to save it but then nothing shows up in the app. Wallabag rejects it as an invalid URL.
