Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

SUBSTACK_PUBLICATION_URL env
Your Substack publication URL (e.g. https://you.substack.com/). Optional if set in ~/.cursor/mcp.json's mcpServers.substack-api.env.
SUBSTACK_USER_ID env
Your Substack numeric user id. Optional if set in ~/.cursor/mcp.json.
SUBSTACK_SESSION_TOKEN secret env
Your Substack session cookie value (the s%3A... string). Required for authenticated calls. Easier path: run `substack-ops auth login --browser chrome` and the cookie is auto-grabbed.
SUBSTACK_OPS_MCP_PATH env
Override path to the mcp.json file the auth layer reads. Defaults to ~/.cursor/mcp.json.
SUBSTACK_OPS_LLM_CMD env
Optional: override the host CLI used by the unattended daemon path (default: auto-detect claude / cursor-agent / codex on PATH). Use {prompt} placeholder if your CLI takes the prompt as an arg.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is substack-ops safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: SUBSTACK_SESSION_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.3.5) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

substack-ops

Standalone Substack CLI + 26-tool MCP server for Cursor MCP, Claude MCP, OpenCode MCP, and any stdio MCP host. Your IDE drafts the replies. Zero AI API keys.

Site → [substack-ops.chavan.in](https://substack-ops.chavan.in) · Source → [06ketan/substack-ops](https://github.com/06ketan/substack-ops) · Glama → [mcp/servers/06ketan/substack-ops](https://glama.ai/mcp/servers/06ketan/substack-ops)

Posts, notes, comments, replies, reactions, restacks, recommendations, search, profiles, feeds, automations, MCP server, Textual TUI. One Python install, one binary, MIT licensed.

TL;DR — MCP-native (no API key, one command)

uvx substack-ops mcp install cursor          # or claude-desktop, claude-code, opencode, print

Restart your host. Then in chat:

"list unanswered comments on post 193866852"

"draft a warm reply to comment 12345"

"post that draft"

Your host's LLM (Cursor's, Claude's) does the drafting via the propose_reply / confirm_reply tools. No ANTHROPIC_API_KEY / OPENAI_API_KEY needed.

Wrong install?

This project is `substack-ops` on [PyPI](https://pypi.org/project/substack-ops/) — install with `uv` / `uvx`, not unrelated `npx` packages that appear when searching “Substack MCP”. Canonical listing: [Glama — 06ketan/substack-ops](https://glama.ai/mcp/servers/06ketan/substack-ops).

Works with (MCP)

These rows help discovery (search keywords); confirm each host’s current MCP docs before upgrading.

Open source–oriented hosts

Host	Documentation	Typical wire-up
OpenCode	OpenCode MCP servers	`uvx substack-ops mcp install opencode`
Continue	Continue	`uvx substack-ops mcp install print` — paste the snippet into Continue’s MCP settings
Zed	Zed	Configure stdio MCP per Zed’s docs
Cline	Cline	MCP setup per extension / marketplace docs
Goose	Goose	MCP extensions per Goose docs

Large commercial stacks

Host	Documentation	Typical wire-up
Cursor	Cursor MCP	`uvx substack-ops mcp install cursor`
Claude (Desktop / Code)	Claude Desktop, Claude Code	`mcp install claude-desktop` / `claude-code`
GitHub Copilot	Copilot	MCP in VS Code / Copilot where supported — use `print` + host docs
ChatGPT	OpenAI	Developer / connector flows — often REST (Slideshot API) for tools without MCP
Google Gemini	Gemini	Gemini CLI / IDE features per Google docs — stdio where supported

OpenCode (copy-paste)

Auto-install:

uvx substack-ops mcp install opencode

Manual (~/.config/opencode/opencode.json):

"mcp": { "substack-ops": { "type": "local", "command": ["uvx", "substack-ops", "mcp", "serve"], "enabled": true } } }

Optional version pin: use ["uvx", "substack-ops==0.3.5", "mcp", "serve"] (replace with current PyPI release).

Setup (dev / from source)

git clone https://github.com/06ketan/substack-ops && cd substack-ops

uv sync uv sync --extra mcp # mcp SDK for the MCP server (recommended) uv sync --extra tui # textual for the TUI uv sync --extra chrome # pycryptodome + keyring for Chrome cookie auto-grab

Auth defaults to ~/.cursor/mcp.json's mcpServers.substack-api.env. Override with env or .env. Or use one of the auth flows in auth login / auth setup.

uv run substack-ops auth verify

uv run substack-ops quickstart # 20-step tour

Command surface

Grouped by intent. Every write defaults to --dry-run; flip with --no-dry-run (and --yes-i-mean-it for the irreversible ones). All writes land in .cache/audit.jsonl and are dedup-checked against .cache/actions.db.

Multi-publication

Every read command accepts --pub . Defaults to your own publication.

substack-ops posts list --pub stratechery --limit 5

substack-ops posts search "ai" --pub stratechery substack-ops recommendations list --pub stratechery

Reply modes

Mode	What it does	Safety
`template`	YAML keyword/regex rules under `src/substack_ops/templates/*.yaml`	dry-run default
`review`	LLM drafts each reply, you `[a]ccept / [e]dit / [s]kip / [q]uit`	dry-run default + manual gate per comment
`bulk`	LLM drafts every comment to `drafts.json`. Edit file, set `action: "approved"`	offline review, dedup-checked on send
`bulk-send`	Posts only items with `action: "approved"`	dry-run default; dedup DB prevents the M2 31-dup-replies regression
`auto`	LLM drafts and posts immediately	requires `--no-dry-run --yes-i-mean-it`, 30s rate limit

After every live note-reply the engine re-fetches the new comment and asserts ancestor_path is non-empty. If empty, the audit row's result_status is flipped to "orphaned" (the M2 bug where parent_comment_id was silently dropped — now caught).

Automations

Built-in presets (auto presets):

like-back — when someone reacts to your note, react to their latest note.
auto-reply — same trigger, but post a templated thank-you.
auto-restack — when a watchlist handle posts a new note, restack it.
follow-back — when someone follows you, follow them back.

Custom YAML rules under ~/.config/substack-ops/auto/*.yaml. Loop with auto daemon --interval 60.
