Quickstart
From zero to your first verified regulatory answer in a few minutes — either inside your AI assistant, or from your terminal.
1. Create an account
Register a free Obsidian account. The free plan includes 50 verified requests per month and access to both the MCP server and the enterprise API.
2a. Use it in your AI assistant (MCP)
Add the Obsidian MCP server to any MCP‑capable client. The endpoint is:
https://mcp.obsidianri.com/mcp
For Claude Desktop, add it under Settings → Connectors; for Cursor, add it to your MCP config. On first use you will be sent through a one‑click sign‑in to connect your Obsidian account. Full per‑client steps are in Connect your client.
Then just ask, in natural language:
What are the latest REACH restrictions on PFAS in the EU?
Your assistant calls the regulatory_search tool and answers with sourced, citation‑backed results.
2b. Call the API (REST)
Prefer code? Create an API key from your account, then call the enterprise API directly. Keys look like sk-… and are sent in the X-API-Key header.
curl https://api.obsidianri.com/search \ -H "X-API-Key: sk-your-key-here" \ --data-urlencode "q=PFAS restrictions under REACH" \ --data-urlencode "jurisdiction=EU" \ -G
The same query works as a tool call in the MCP and as a request to the API — both read the same verified database.
