Our reading of midnight-cast, from the data

midnight-cast is a science & research MCP server from kanasjnr, listed in the official MCP Registry.

We haven't measured its tool list yet, so its token cost is unknown.

With 1 GitHub stars it ranks #323 of 1,435 science & research servers we index.

It runs locally on your machine over stdio and needs 2 secrets (BLOCKFROST_PREPROD_PROJECT_ID, BLOCKFROST_MAINNET_PROJECT_ID); use a scoped, least-privilege key.

Install midnight-cast MCP server

claude mcp add midnight-cast -e BLOCKFROST_PREPROD_PROJECT_ID='<blockfrost-preprod-project-id>' -e BLOCKFROST_MAINNET_PROJECT_ID='<blockfrost-mainnet-project-id>' -- npx -y midnight-cast mcp
