JARS.LT exposes a documented REST API at https://api.jars.lt/api/v1, a streamable HTTP MCP server at https://api.jars.lt/mcp, and an official npm-distributed Node.js SDK; the REST API uses an API key, while the MCP server supports both API key and OAuth 2.0 via well-known discovery.

Create an account or sign in on JARS.LT, choose a plan from Pricing, then obtain your API key from your account to use in the x-api-key header. The docs and official SDK both instruct developers to use an API key from JARS.LT.

JARS MCP OAuth client and access tokenoauth2Set up OAuth ↗

For MCP clients that support OAuth, use JARS's OAuth 2.0 discovery metadata at authorization server metadata and protected resource metadata. JARS supports Dynamic Client Registration, so an AI client can register itself at https://api.jars.lt/register, then complete the authorization-code flow to obtain a bearer access token for scopes like mcp:read.
