M3U8 stream downloader for browser extensions and MCP
This project downloads M3U8 live streams to local disk from a browser extension. It also exposes an MCP tool definition so an agent can call the downloader through JSON-RPC 2.0 and JSON Schema.
Builders who want a browser extension or agent tool for saving HLS streams locally.
You can capture live streams to disk instead of relying on the website or player.
What it does
M3U8 stream download
Saves live HLS streams from the browser to local disk.
Browser extension builds
Includes separate `v2` and `v3` extension implementations with manifests and runtime code.
MCP tool definition
Ships `v3/mcp/mcp.json` so coding agents can call the downloader as a tool.
Stream blocking controls
Includes `v3/network/blocked.json` for sites that request their streams be ignored.

Content Creators
If you want this extension to ignore your website's streams, please request a pull merge for blocked.json, or open a bug report. To ensure protection against misuse, I also require an email that includes the link to the pull request from the owner of the website.
MCP Server
This extension can be used with coding agents such as OpenCode. Read FAQs page for more info. Also check the mcp.json (LLM tool definition) file which defines available tools for an agent, using JSON-RPC 2.0 as the envelope and JSON Schema for input/output.
