This file is a client implementation that tests outputSchema servers,
so it belongs in the client examples directory rather than server examples.
Updated file paths in error messages to reflect the new location.

- Remove tool() overload that takes a config object with callback
- Add new registerTool() method that separates config from callback
- Extract common tool registration logic into _createRegisteredTool() helper
- Update all tests to use registerTool() for tools with output schemas
- Update examples to use registerTool() and high-level Client API
- Add comment noting that output schema validation only works with high-level API
This change improves API clarity by using a distinct method for tools with
output schemas while maintaining backward compatibility.

- Add outputSchema field to Tool type and RegisteredTool interface
- Make content field optional in CallToolResult
- Update ListToolsRequestSchema handler to include outputSchema in tool list responses
- Add support for structuredContent in tool results
- Update examples to handle optional content field
- Add tests for new outputSchema and structuredContent functionality
- Update ToolCallback documentation to clarify when to use structuredContent vs content
This change enables tools to define structured output schemas and return
structured JSON content, providing better type safety and validation for
tool outputs.

When an SSE client connects with a custom path (e.g., /api/v1/custom/sse),
ensure the endpoint URL maintains the same base path structure but with
/messages instead of /sse. This fixes issues where custom endpoints were
getting collapsed to the root path.
Should fix issues reported in modelcontextprotocol/inspector#313 and #296
Tests demonstrating the issue were added in PR #439🤖 Generated with [Claude Code](https://claude.ai/code)

- simpler test for empty object
- only test public zod properties (parse, safeParse)
Confirmed that vendored-library tests still pass. Note that you need the --testPathIgnorePatterns to avoid the __tests__ directory (this is what was breaking the build):
$ npm test -- --testPathIgnorePatterns="vendor"
Previously, this check was `value instanceof ZodType`, which breaks if
the user is using a different version of Zod than the library. Instead,
do the check using the structure of the input object rather than its
prototype chain.
Additionally, this adds a vendored version of Zod to use for tests, which
ensures that regressions like this would be caught next time.
- Add optional scope parameter to startAuthorization function signature
- Include scope in authorization URL query parameters when provided
- Update auth function to pass through scope from provider.clientMetadata
- Add tests to verify scope is correctly included/excluded from auth URL
This enhancement allows clients to specify authorization scopes during the OAuth flow.
* In src/client/index.test.ts added tests:
- "should connect new client to old, supported server version"
- should negotiate version when client is old, and newer server supports its version"
- "should throw when client is old, and server doesn't support its version"
* In src/client/index.test.ts added tests:
- "should connect new client to old, supported server version"
- should negotiate version when client is old, and newer server supports its version"
- "should throw when client is old, and server doesn't support its version"
* This fixes#378
* In types.ts
- set LATEST_PROTOCOL_VERSION to "2025-03-26"
- add "2025-03-26" to SUPPORTED_PROTOCOL_VERSIONS
* In auth.test.ts
- in test "returns metadata when discovery succeeds"
- expect "MCP-Protocol-Version" to be "2025-03-26"
