substack-ops
Substack CLI + 26-tool MCP server. Your IDE drafts replies via propose_reply. No API keys.
Using substack-ops in Claude, Cursor, Gemini CLI, Cline, or Zed?
MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).
Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

- - Semantic screen only - the deterministic conformance probe has not run on this server
- - Confidence is reported but not yet calibrated (v1)
- - Screen reads the tool description, not the live behavior
- - advisory
- - registry description only no input schema
- - screen model 8b
Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

That verdict was true at screening time (snapshot 2026-07-31).
Contracts can change after screening, with no version bump. The gate pins substack-ops’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Optional if set in ~/.cursor/mcp.json's mcpServers.substack-api.env.
SUBSTACK_USER_IDYour Substack numeric user id. Optional if set in ~/.cursor/mcp.json.
SUBSTACK_SESSION_TOKENYour 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_PATHOverride path to the mcp.json file the auth layer reads. Defaults to ~/.cursor/mcp.json.
SUBSTACK_OPS_LLM_CMDOptional: 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.
