<!-- Provide a brief summary of your changes --> ## Motivation and Context <!-- Why is this change needed? What problem does it solve? --> This is one attempt to resolve https://github.com/modelcontextprotocol/registry/issues/169. Instead of adding a new "constant" argument type, I expanded the existing positional one and just dropped the `value_hint` requirement. I am not sure if this has VS Code impact @sandy081, @connor4312. Also, removed unneeded release_date values from the samples. ## How Has This Been Tested? <!-- Have you tested this in a real application? Which scenarios were tested? --> I tested the current server.json samples in the repo against the new (less strict) schema. Of course they passed (aside from an unrelated bug in my previous NuGet sample 🤦). ## Breaking Changes <!-- Will users need to update their code or configurations? --> ## Types of changes <!-- What types of changes does your code introduce? Put an `x` in all the boxes that apply: --> - [ ] Bug fix (non-breaking change which fixes an issue) - [ ] New feature (non-breaking change which adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [x] Documentation update ## Checklist <!-- Go over all the following points, and put an `x` in all the boxes that apply. --> - [x] I have read the [MCP Documentation](https://modelcontextprotocol.io) - [x] My code follows the repository's style guidelines - [ ] New and existing tests pass locally - [ ] I have added appropriate error handling - [x] I have added or updated documentation as needed ## Additional context <!-- Add any other context, implementation notes, or design decisions --> |

Registry API
There are a variety of use cases where an MCP Server Registry API is useful to the MCP ecosystem. At least the following:
- Implementation of a centralized, publicly available catalog of all publicly accessible MCP server implementations
- Implementation of a private catalog of MCP server implementations exclusively accessible by a specific group of people (e.g. a single enterprise)
These scenarios would benefit from a standard "MCP server registry API" specification that they could potentially compose, as well as share resources (like SDK implementations).
The centralized, publicly available catalog ("Official MCP Registry") needs additional constraints that need not apply to the broader "MCP server registry API"
