@modelcontextprotocol/core\n\nCanonical public home for the [Model Context Protocol](https://modelcontextprotocol.io) specification and OAuth/OpenID **Zod schemas**.\n\nThese are the exact schema constants the SDK validates protocol and OAuth/OpenID payloads against internally. The `@modelcontextprotocol/server` and `@modelcontextprotocol/client` packages keep a Zod-free public surface, so this package exists as the supported place to import the\nraw schemas when you need to validate or parse MCP messages yourself.\n\n## Install\n\n```sh\nnpm install @modelcontextprotocol/core\n```\n\n## Usage\n\n```ts\nimport { CallToolResultSchema } from '@modelcontextprotocol/core';\n\n// Throws on invalid input; returns the typed result on success.\nconst result = CallToolResultSchema.parse(payload);\n\n// Or non-throwing:\nconst parsed = CallToolResultSchema.safeParse(payload);\nif (parsed.success) {\n    // parsed.data is a fully typed CallToolResult\n}\n```\n\n## Scope\n\nThis package exports **only** Zod schema constants (`*Schema`), in two groups:\n\n- the MCP **spec** schemas — `CallToolResultSchema`, `ListToolsResultSchema`, …; and\n- the **OAuth/OpenID** auth schemas — `OAuthTokensSchema`, `OAuthMetadataSchema`, `IdJagTokenExchangeResponseSchema`, … (the schemas v1 exposed from `@modelcontextprotocol/sdk/shared/auth.js`).\n\nThe corresponding TypeScript types, error classes, enums, and type guards are part of the public API of [`@modelcontextprotocol/server`](https://www.npmjs.com/package/@modelcontextprotocol/server) and\n[`@modelcontextprotocol/client`](https://www.npmjs.com/package/@modelcontextprotocol/client).\n\n> **Migrating from v1?** In v1 these schemas were imported from `@modelcontextprotocol/sdk/types.js` (spec schemas) and `@modelcontextprotocol/sdk/shared/auth.js` (OAuth/OpenID schemas). Point those `*Schema` imports at `@modelcontextprotocol/core` and your existing `.parse()` /\n> `.safeParse()` calls keep working unchanged.\n","readmeFilename":"README.md"}
