substack-ops MCP Server

What this does

substack-ops exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation.

Requirements

This server needs the following environment variables to be set before it can run:

SUBSTACK_PUBLICATION_URL
SUBSTACK_USER_ID
SUBSTACK_SESSION_TOKEN
SUBSTACK_OPS_MCP_PATH
SUBSTACK_OPS_LLM_CMD

Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).

How do I install substack-ops?

Run the Claude Code command in the install section to add substack-ops to Claude Code, or copy the ready-made config for your client from the install section on this page. Restart your client afterwards and the tools appear in your next conversation.

This page carries setup and config for Claude Code, Claude Desktop, Cursor and VS Code. Any other MCP client that accepts a standard server config can connect to substack-ops as well.

Yes. Before it can run, set these environment variables: SUBSTACK_PUBLICATION_URL, SUBSTACK_USER_ID, SUBSTACK_SESSION_TOKEN, SUBSTACK_OPS_MCP_PATH, SUBSTACK_OPS_LLM_CMD. They go in the env block of your MCP config.
