Loom Transcript MCP (Fixed)

A working Model Context Protocol (MCP) server for fetching transcripts and comments from Loom videos.

This is a fixed fork of @daanvanhulsen/loom-transcript-mcp that resolves the 400 GraphQL errors caused by recent changes to Loom's API.

What Was Fixed

The original package stopped working due to three critical bugs:

Array vs Object: The original code sent GraphQL requests as an array [{...}] instead of a plain object {...}, which Loom's API now rejects with a 400 error.
Missing Headers: Added proper browser-like headers including Accept and User-Agent to pass Loom's validation.
Response Parsing: Fixed response data access from response.data[0].data to response.data.data to match the correct response format.
