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:

  1. 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.

  2. Missing Headers: Added proper browser-like headers including Accept and User-Agent to pass Loom's validation.

  3. Response Parsing: Fixed response data access from response.data[0].data to response.data.data to match the correct response format.

Installation

{ "mcpServers": { "loom-transcript": { "command": "npx", "args": ["-y", "@bstyler/loom-transcript-mcp"] } } }

Docker
