"How to obtain an API key" matching MCP connectors:
GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
An MCP server for Perigee, the open-source 3D viewer of the artificial objects orbiting the Earth, the Moon and Mars and of the spacecraft crossing the solar system. It lets an AI assistant (a teaching assistant, for example) answer questions such as “how far is Mars from the Earth on 1 December 2026?”, “where is the ISS now?” or “what is Lucy's mission?”, and hand the student a live 3D view, with how each number was obtained, from which data, how fresh and how accurate.
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.
Turn Mermaid or an indented outline into an editable flowchart link. Completely free, no API key.
No-signup IoT backend: device names, sensor readings, history and live charts. No API key needed.

Option analytics over the SYNTH sample or a permitted chain: Greeks, positioning, payoffs, plots.
Build surveys, read responses and make reports in SurveyNinja from an AI assistant.
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

Turn your data into map images of countries, states, counties and ZIP codes with Ultimaps MCP server. Each map comes with a link to Ultimaps Studio, where you can keep editing it, export it, or publish an interactive version. No account needed: 30 maps per hour, PNG up to 1600px, with Ultimaps attribution.

Turn data into infographics (PNG/SVG): 90+ templates, or KPI cards, charts, timelines and maps.
Send a table, get chart code that fits it using ontology + AI: interactive D3 you own (or Plotly and matplotlib for Python). It measures your data's shape first and rules out chart types the data can't honestly support. Sign in with OAuth using a RegiaBI account (a free trial is enough). Your rows are profiled in memory and never stored. Expect high quality results compared to the alternative of agent wrangling.

Dashboards generate themselves on source connect.
