Packages
This SDK consists of three main packages:
-
ModelContextProtocol.Core - For projects that only need to use the client or low-level server APIs and want the minimum number of dependencies.
-
ModelContextProtocol - The main package with hosting and dependency injection extensions. References
ModelContextProtocol.Core. This is the right fit for most projects that don't need HTTP server capabilities. -
ModelContextProtocol.AspNetCore - The library for HTTP-based MCP servers. References
ModelContextProtocol.
Getting Started
To get started, see the Getting Started guide in the conceptual documentation for installation instructions, package-selection guidance, and complete examples for both clients and servers.
