"How to invoke Claude code or API" matching MCP connectors:
GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
Read-only access to your own crypto portfolio across 11+ exchanges and 20+ chains: holdings, full history, FIFO cost basis and P&L, fees and income. Ask Claude or ChatGPT about your portfolio; the connector can never trade, move funds or act as a login.
No-signup IoT backend: device names, sensor readings, history and live charts. No API key needed.
Validate Mermaid syntax and get error details your coding agent can use to correct a diagram. Check the source again before adding it to your documentation. Validation works without saving a diagram. Render SVG, PNG, or PDF, save diagrams privately, and publish selected snapshots. Your existing agent writes and corrects the source; MermaidDesk checks and renders it. Validation checks syntax, not whether a diagram accurately describes a system. Connect through MCP with Streamable HTTP and a scoped bearer API key. Enable MERMAID_RENDER for validation and rendering. A REST API is also available. MCP setup: https://www.mermaiddesk.com/developers/mcp REST API guide: https://www.mermaiddesk.com/developers/api
