-# One-time setup for the Instagram MCP server. Each OpenSwarm user runs this
-# once on their machine; it installs the ShawnMadadha/instagram_dm_mcp fork
-# (carries the per-tool rate limiter that protects accounts from anti-abuse
-# bans) into ~/.openswarm/instagram-mcp/ and pip-installs its dependencies
-# into a local venv. Re-running upgrades to the latest version.
-#
-# Why a fork: trypeggy/instagram_dm_mcp upstream does not have the rate
-# limiter yet. PR is open at trypeggy/instagram_dm_mcp#12.
