Common questions
Is Elc Toolkit safe?
It passed 0 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?
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 3 months 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 in developer mode.
What can I use instead?

"Is my engineering org top-heavy?" "How do I justify a conference/community sponsorship budget internally?" "Should I start a local engineering-leadership meetup?"
Your AI already gets asked these. Now it can answer with first-party data from Engineering Leaders Community: 3,300+ engineering leaders across Prague, Brno, Bratislava and Kraków, running since 2019, instead of guessing.
This is a remote MCP server. No install, no API key. One URL:

Tools
| Tool | The question it answers |
|---|---|
benchmark_leadership_ratio | Is my org's manager-to-senior-IC ratio healthy? Compares your split against the ELC peer baseline (69% manager / 21% senior IC across 3,300+ CEE leaders) |
build_partnership_business_case | How do I justify a partnership budget for ELC internally? Real reach numbers, goal-specific framing, and a forwardable approval email — no invented pricing |
plan_leadership_career_path | The engineering manager role is changing. Which path is mine, and what do I do in the next 6 months? 7 questions, one of three paths (Grow up, Go deep, Go product), and a month-by-month plan with a proof per month. Built from ELC meetup #43 |
assess_community_launch_readiness | Should I start an engineering-leadership meetup in my city? 5-question readiness check straight from ELC's own new-city launch playbook |
