Nothing serious here today

Today is the operative word: we check Loopgantt every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This one needs environment variables set before it will start: LOOPGANTT_API_KEY (Optional. Enables the account tools create_project / list_projects (https://loopgantt.com/settings/api-keys).). The author declared them in the registry entry; get the values from the project itself.

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

gantt

create_gantt

Create a Gantt chart from a task list — no account or API key needed. YOU author the plan: list the tasks in execution order with realistic working-day durations and dependencies (0-based positions of earlier tasks; use { task, type, lag } for start-to-start/finish-to-finish links or lag). Milestones have duration 0. Only add a dependency where a task truly needs another one finished - independent tasks should run in PARALLEL (share a predecessor, or take no dependencies at all and start at the project start). Group tasks into top-level phases for a structured plan/WBS: the phase task gets isPhase: true, its tasks get parent = the position of the phase. LoopGantt schedules it with its critical-path engine and returns a picture of the chart, the dates, the critical path and a link where the user can view, export (PNG/PDF) and save the chart. Always show the user the link. Tasks with a due date take deadline: YYYY-MM-DD (a marker - the reply reports the fit). Use create_gantt when the user wants a chart to open, export or save; use schedule_project instead for what-if date math where nothing should be stored.

schedule

schedule_project

Compute a schedule without storing anything: dates, critical path, float and project end for a task list (same input shape as create_gantt; name optional). Use it to answer "what is the critical path?", "when would this finish?", "how much slack does X have?". Use create_gantt when the user wants a chart they can open.

template

get_template

Get one industry template by slug: its task list with durations, ready to adapt and pass to create_gantt.

templates

list_templates

List LoopGantt's industry project templates with task counts and typical durations. Pick one, fetch it with get_template, adapt it, then create_gantt.

Loopgantt — questions

Answers built from our own checks of this server.

What can Loopgantt do?

It exposes 4 tools, read directly from the server on our last check. Among them: create_gantt, get_template, list_templates, schedule_project. 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 Loopgantt working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 409 ms. The bar chart above shows every period we have measured.

How do I connect Loopgantt?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Loopgantt need an API key?

No. Loopgantt completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Loopgantt?

It answers our handshake in 409 ms on average, which is faster than 37% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use Loopgantt?

The npm package @loopgantt/mcp-server was installed 41 times in the last week. Week over week that is -13%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
