MCPHost

MCPHost is a client for the Model Context Protocol that runs in a browser and connects to MCP servers from one place. It is described as a universal MCP client, and its interface is built around browsing tools, reading resources, using prompts, and chatting with LLMs.

Its core capabilities focus on working across multiple servers at once. MCPHost offers a unified interface for multiple MCP server connections, built-in LLM chat with configurable AI providers, and support for tools from all connected servers in a single conversation. It also supports OAuth 2.0 and PKCE, with automatic token refresh and dynamic client registration, and it accepts bearer tokens or no authentication when adding a server. For communication, it uses SSE and Streamable HTTP transports for live updates and bi-directional interaction. The product says it covers the full protocol spec, including tools, resources, prompts, sampling, elicitation, progress, and logging.

The service is delivered from the browser and is launched through its app. It includes 50+ pre-configured integrations, with named examples including Notion, Linear, Stripe, Vercel, Cloudflare, Sentry, Figma, HubSpot, PayPal, PubMed, Atlassian, Canva, Asana, Square, Box, and Intercom. The getting-started flow is presented as three steps: add a server, authenticate, and start building.
