What it can do
Tool names and descriptions exactly as the server reported them on Nov 12, 2026. The maker wrote them, not us; we show them as plain text.
start_sessionStart a guided session to estimate app development cost, scope an MVP, and generate a software PRD. No portal account or personal access token is required. Call it with no arguments unless the user already named Review each step (clarify_first) or Run it for me (auto_complete). D
send_turnContinue an app cost estimate by sending the user's answers or requested changes to the MVP scope, user stories, requirements, or technical specification. Pass their exact words in input_as_text, even when next_tool is send_action. Compact replies such as "1A, 2B" are valid. Pres
send_actionSubmit the user's pending choice. Set action_type to a value from pending_gate_payload.allowed_actions. In Review each step, action_type is required; confirmed_by_user=true is preferred and is not a substitute for it. In Run it for me, omit action_type and payload to advance one
get_estimate_statusRead the current app cost estimate without advancing it. Returns flow_stage, pending_gate, and pending_gate_payload. After submission it also returns post_submit_notice and post_submit_links: relay the notice verbatim, keep every URL, and do not add an email-delivery caveat. Pass
submit_prdLooks like an instruction to the AISubmit the completed software PRD and app development estimate for email delivery and portal project creation.

Common questions
Is ChatStack - App Cost Estimator safe?
It passed 1 of 3 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?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 15 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).
What can I use instead?
