# Voyagier web app (travel.voyagier.com) > This is the signed-in Voyagier web app for travelers and travel advisors. Almost every page needs a Voyagier account, so a fetch without a session returns the sign-in page. AI agents should use the MCP server or the CLI below, not this web app. ## Connect an agent - [Voyagier MCP server](https://mcp.voyagier.com/api/mcp): Streamable HTTP MCP endpoint. Search flights, hotels and activities, build trip plans, and take a plan to a price-gated checkout. Sign-in is OAuth 2.1 with standard discovery (RFC 9728 and RFC 8414), so MCP clients run the sign-in flow themselves. Self-serve: a person signs up or signs in at travel.voyagier.com and approves once. Any Voyagier account can approve, and approval turns on agent access for that account. No invite, plan upgrade or API key is needed. - [Voyagier CLI](https://www.npmjs.com/package/@voyagier/cli): `npm install -g @voyagier/cli`, then `voyagier login`. One command per MCP tool. The CLI uses a personal access token. Tokens need API access, which Voyagier grants on request (apis@voyagier.com). - [Voyagier for AI agents](https://www.voyagier.com/agents): Overview, setup for each MCP client, and API access requests. ## About Voyagier - [Voyagier llms.txt](https://www.voyagier.com/llms.txt): Company, product and booking details. ## Shared trips and profiles Pages under /trips/ and /users/ are trips and profiles that people chose to share by link. Read one when a person gives you its link. Do not index, collect or republish them.
