Check for naming validation for Tool. This validation follows the MCP SEP986 naming guidance.

Name will be checked before MCP initialization (where specs version is confirmed). Hence, we will be implementing this across all versions and endpoints.

This will be a breaking change for user that currently uses other special character as name (other than _, -, .)

Summary of Changes

Hello @Yuan325, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a crucial enhancement to enforce strict naming conventions for resources within the system. By integrating a new validation mechanism, it ensures that all resource names conform to the specified Model Context Protocol (MCP) SEP986 guidance, promoting data integrity and system consistency. This validation is performed early in the configuration loading process, preventing malformed names from being used.

Highlights

  • Resource Naming Validation: Implemented new validation for resource names, adhering to the MCP SEP986 naming guidance. This ensures consistency and compliance with defined standards.
  • Early Enforcement: The naming validation is performed before MCP initialization, applying across all versions and endpoints to prevent malformed names from entering the system early in the configuration loading process.
  • Validation Logic: A new NameValidation function has been introduced. It checks that resource names are between 1 and 128 characters in length (inclusive) and consist only of uppercase/lowercase ASCII letters, digits, underscores, hyphens, and dots.
  • Integration into Configuration Loading: The NameValidation function is integrated into the UnmarshalYAML methods for various configuration types, including SourceConfigs, AuthServiceConfigs, EmbeddingModelConfigs, ToolConfigs, ToolsetConfigs, PromptConfigs, and PromptsetConfigs, ensuring all configured resource names are validated.
  • Comprehensive Unit Tests: New unit tests for the NameValidation function have been added to internal/server/server_test.go, covering a wide range of valid and invalid naming scenarios to ensure robustness.

Code Review

This pull request introduces resource naming validation, which is a great addition for ensuring data integrity based on MCP SEP986. The implementation adds a NameValidation function and applies it consistently across various configuration unmarshalling processes. I've identified a performance improvement opportunity in the NameValidation function by compiling the regular expression only once. I've also pointed out a couple of typos in the error messages and suggested updating the tests accordingly. Overall, the changes are well-structured and the addition of tests is appreciated.

Let's only update for tool names right now and not enforce this for other resources.

SEP986 [naming
guidance](https://github.com/alexhancock/modelcontextprotocol/blob/1b1eb60ec48442494e617d7dffafb3270b5126af/docs/specification/draft/server/tools.mdx#tool-names).

Name will be checked before MCP initialization (where specs version is
confirmed). Hence, we will be implementing this across all versions and
endpoints.

This will be a breaking change for user that currently uses other
special character as name (other than `_`, `-`, `.`)
