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
AcceptandUser-Agentto pass Loom's validation. -
Response Parsing: Fixed response data access from
response.data[0].datatoresponse.data.datato match the correct response format.
