Chartbrew connects databases and APIs to dashboards and reports. Its official MCP server lets AI assistants find dashboards and datasets, read chart results, explore supported data sources, and create datasets and chart previews. Connect directly to the hosted server with OAuth or a Chartbrew API key. Access follows your Chartbrew team, role, and approved permissions. Review chart previews in Chartbrew before adding them to a dashboard. No local installation is required.
TinyTo shortens links and shows what happens after the click: country, device, weekday/hour heatmap. It also generates QR codes for free, with an optional logo, downloaded as PNG or SVG — no account, nothing uploaded. Dynamic QR codes point at an editable short link, so a printed code can be repointed without reprinting.
Cookieless web analytics for your sites: visitors, pages, sources, goals and speed.
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.

Find and install React charts from your coding agent: search 132 chart types by the question your data answers (100 free and MIT), get each type's props and the JSON Schema of its data, the component files and the design tokens. No auth needed; a Chartory registry token unlocks the code of the paid types.
No-signup IoT backend: device names, sensor readings, history and live charts. No API key needed.
Live, editable canvas for AI agents — author graphs via MCP, then watch and reroute runs live.
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
