Standard output carries only protocol messages; diagnostics belong on standard error. Both protocol eras share… - [Streamable HTTP client](https://recursiveai.org/onemodelcontext/docs/http-client/index.md): ModelContext.ConnectAsync("https://host/mcp") (or ConnectAsync(new Uri(...)), or ContextTransport.Http(uri, client, options)) connects over Streamable… - [Streamable HTTP server and the listener](https://recursiveai.org/onemodelcontext/docs/http-limits/index.md): StreamableHttpEndpoint serves both protocol eras on one path over the small IHttpExchange abstraction. Every limit below is a property of… ## Tools, resources and prompts - [Tool signatures and JSON Schema](https://recursiveai.org/onemodelcontext/docs/tool-schemas/index.md): The [Tool] source generator and the reflection quick path (server.Tool("name", delegate)) write the same schema for the same signature. This note is that… - [Asking the client for input](https://recursiveai.org/onemodelcontext/docs/multi-round-trip/index.md): A tool, prompt or resource handler can ask the client for input in the middle of a request: ctx.ConfirmAsync, ctx.ElicitAsync, ctx.SampleAsync… ## Authorization - [Resource server](https://recursiveai.org/onemodelcontext/docs/resource-server/index.md): An MCP server that listens on HTTP can require OAuth 2.1 bearer tokens. OneModelContext plays the resource server role: it serves protected resource… - [OAuth client](https://recursiveai.org/onemodelcontext/docs/oauth-client/index.md): OAuthClient signs a program in to an OAuth-protected server and keeps its tokens fresh. It lives in the RecursiveAI.OneModelContext.OAuth namespace, which… - [Authorization server](https://recursiveai.org/onemodelcontext/docs/authorization-server/index.md): A .NET application can be the OAuth 2.1 authorization server for its own MCP endpoint, so it can act as a connector for hosted clients without a… ## Extensions and packages - [Extensions](https://recursiveai.org/onemodelcontext/docs/extensions/index.md): An extension adds methods, notifications, _meta keys or capability settings to the Model Context Protocol (MCP) without a new core revision. The mechanism… - [Hosting and Extensions.AI](https://recursiveai.org/onemodelcontext/docs/adapters/index.md): Two small packages, each referencing the core package and the one Microsoft package it adapts. - [Entity Framework Core and OneLite stores](https://recursiveai.org/onemodelcontext/docs/stores/index.md): RecursiveAI.OneModelContext.EntityFrameworkCore keeps the authorization server's state and a client's tokens in your own database, so several instances of… ## Testing and history - [Conformance](https://recursiveai.org/onemodelcontext/docs/conformance/index.md): OneModelContext is checked against the protocol's official conformance suite, run as a black box: it is installed from its published package and driven… - [Interop](https://recursiveai.org/onemodelcontext/docs/interop/index.md): OneModelContext is checked against other implementations of the protocol, run as black boxes: installed from their published releases at pinned versions… - [Changelog](https://recursiveai.org/onemodelcontext/docs/changelog/index.md): All notable changes are recorded here, following Keep a Changelog.
