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.

Example request: "Turn our customer onboarding steps into a simple flowchart I can share with the team."

How to connect: Not 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. 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.

Tools:
- create_flowchart: Create 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_chart: Create 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: Present
- create_funnel_chart: Create 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_chart: Create 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 nee
- create_timeline_chart: Create 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 durati
- create_erd_chart: Create 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_chart: Edit 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 — flowchart
- get_chart: Fetch a chart's current spec (JSON) and editable source text, plus its share URL.
- list_charts: List your CalderFlow charts (id, title, type, share URL), newest first.
- delete_chart: Permanently delete a chart you own.
