Turn plain language into editable flowcharts, funnels, timelines and data models.
Connects to CalderFlow to build presentation-ready diagrams: flowcharts and decision trees, chevron process charts, conversion funnels, lifecycle curves, timelines and entity-relationship data models. Muse can create, edit, list and share charts, adjusting nodes, steps and icons on request.
Try asking Muse: "Turn our customer onboarding steps into a simple flowchart I can share with the team."

Not in Muse's Connectors list yet, but Muse can still use it. Copy the request below and paste it into Muse. Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

CalderFlow is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Screened, no issues found
Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.
create_flowchartCreate a presentation-ready flowchart or architecture diagram from Mermaid source. Use for branching processes, decision trees, and system architecture. Rules: start with 'flowchart TD' or 'flowchart LR'; solid arrows only (-->, optionally with |labels|); node shapes: A[Process] create_chevron_chartCreate a sequential/chevron chart: a linear sequence of steps, phases, or stages (e.g. onboarding steps, project phases). NOT for branching logic — use create_flowchart for that. Include a 1-2 sentence description per step to make it presentation-ready. Aim for 4-6 steps: Presentcreate_funnel_chartCreate a funnel chart for filtering/narrowing processes where quantities reduce per stage (conversion funnels, pipelines). Include stage values when numbers are available; set conversionRates for proportional widths.create_lifecycle_chartCreate a lifecycle chart: phases across the top and milestones plotted on a curve. Each milestone has a level 1-10 setting its height — bell curves, S-curves, dips all emerge from levels. Use for product lifecycles, customer journeys, adoption/maturity curves. Every milestone neecreate_timeline_chartCreate a timeline of events in chronological order (roadmaps, company history, sprint/release schedules). Every event needs a marker: supplied dates, relative time for a proposed plan, or Phase 1, Phase 2, etc. for an undated process. Never invent factual dates or measured duraticreate_erd_chartCreate an entity-relationship diagram (database schema / data model) with typed fields, PK/FK markers, and crow's-foot relationships. Entity names UPPER_SNAKE_CASE, 3-8 focused fields each.edit_chartEdit an existing chart. Call get_chart first to see its current spec, then pass tool_calls (surgical edits) and/or mermaid (full source replacement, flowchart/ERD only). A create_* tool call replaces the chart's data wholesale and can switch its type. Valid tool names — flowchartget_chartFetch a chart's current spec (JSON) and editable source text, plus its share URL.list_chartsList your CalderFlow charts (id, title, type, share URL), newest first.delete_chartPermanently delete a chart you own.https://www.calderflow.com/mcpNot in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use CalderFlow to help me. It is a free service with an MCP server at https://www.calderflow.com/mcp. It needs an API key from CalderFlow; ask me to enter it through your secure credential prompt. Ask me before you share anything with it." Muse asks before it shares anything with the app's site.

At the last check (November 15, 2026, 17:45 UTC) the endpoint was working, answering in 286ms. Over the last 7 days it answered 100% of health checks. It is checked every 15 minutes.
It was screened on November 15, 2026 with the result "screened, no issues found". Screening checks the domain against threat feeds and reads the tools for hidden instructions and requests for passwords or card numbers. It cannot see the server's code, so grant only the access you need.
It exposes 10 tools, including create_flowchart, create_chevron_chart, create_funnel_chart, create_lifecycle_chart. For example, you could ask Muse: "Turn our customer onboarding steps into a simple flowchart I can share with the team."
