I'm In! Sign-up Sheets missed 3 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

draft
draft_sheet_link
Turn the user's email, notes, flyer text or description of their event into a link that opens im-in.events with those words in the Describe it box. Pressing Make my draft there builds the whole sign-up sheet (dates, times, place, every role with its count, waitlist, reminders and its look) for the user to check and publish. Creates nothing and needs no account.
signup
create_signup_sheet
Create a live sign-up sheet on im-in.events from a title, slot names and a time zone. Returns the shareable sheet URL and emails a private manage and claim link to owner_email, the user's own address. One sheet per owner email a day.
templates
list_templates
List I'm In! sign up sheet templates (potluck, meal train, volunteer shifts, ...) with their prefilled slots.

I'm In! Sign-up Sheets — questions

Answers built from our own checks of this server.

What can I'm In! Sign-up Sheets do?
It exposes 3 tools, read directly from the server on our last check. Among them: create_signup_sheet, draft_sheet_link, list_templates. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is I'm In! Sign-up Sheets working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 678 ms. The bar chart above shows every period we have measured.
How do I connect I'm In! Sign-up Sheets?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does I'm In! Sign-up Sheets need an API key?
No. I'm In! Sign-up Sheets completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is I'm In! Sign-up Sheets?
It answers our handshake in 678 ms on average, which is faster than 16% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
