## Motivation and Context
- Add MCPB as a new registry_name option
- Add file_hashes field to package model for integrity verification
- Implement URL validation restricting MCPB packages to GitHub/GitLab
hosts
- Require SHA-256 hash for all MCPB packages
- Add example MCPB package in documentation
- Update schemas and OpenAPI specification
See issue #260

<!-- Provide a brief summary of your changes -->
This PR serves as a placeholder and brings together all of the changes
related to supporting vendor extensions passed through the API. The idea
is to have a single place to track and review the work as it comes
together (even if it’s still a bit of a work in progress).
**The changes in this PR cover:**
* Updates on the data model
* Updates on both databases (in-memory and postgresql), added a new
table to PSQL for tracking the extensions leaving the server table only
for the clean server.json properties
* Updates the seed.json file (thus the big line change)
* Adds a seed-migrate tool to help migrating an existing seed file to
the new format
* Updates the seed import mechanism to support this
* Updates the existing tests - unit, integration and validation tests
* Adds the publish handler to the OpenAPI spec (it was missing)
* Fixes linting errors
* Updates on the API side on (publish, list, get) to support the new
format of `ServerResponse` -
```

"server": {},
"x-io.modelcontextprotocol.registry": {}, /*not available for publish since this gets populated by the registry*/
"x-publisher": {}

## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->
Motivated by the discussions in:
https://github.com/modelcontextprotocol/registry/discussions/284
## How Has This Been Tested?
<!-- Have you tested this in a real application? Which scenarios were
tested? -->
Locally and by running all of the tests
## Breaking Changes
<!-- Will users need to update their code or configurations? -->
Yes, it changes both the API and the format of the seed file

This PR simplifies the seed data import configuration based on
maintainer feedback by removing command line flags and using a clearer
environment variable name.
## Key Changes
### Configuration Simplification
- **Renamed**: `MCP_REGISTRY_SEED_FILE_PATH` → `MCP_REGISTRY_SEED_FROM`
- **Removed**: `--seed-file-path` command line flag to eliminate
configuration complexity
### Improved User Experience
Users now configure seed data import using a single, clear environment
variable:
```bash
# Before (multiple ways to configure)
MCP_REGISTRY_SEED_FILE_PATH=data/seed.json ./registry
./registry --seed-file-path=data/seed.json
# After (simplified single method)
MCP_REGISTRY_SEED_FROM=data/seed.json ./registry
```
### Registry Composability
The composability workflow is now simplified while maintaining all
functionality:
```bash
# Start first registry with seed data
MCP_REGISTRY_SEED_FROM=data/seed.json ./registry
# Start second registry importing from first via pagination
MCP_REGISTRY_SEED_FROM=http://localhost:8080 ./registry
```
## Technical Implementation
- Maintains full backward compatibility for import functionality
- All existing seed data sources continue to work (local files, HTTP
URLs, registry URLs)
- Automatic pagination through `/v0/servers` endpoint remains unchanged
- Configurable delays between requests preserved
## Benefits
- **Reduced complexity**: Single configuration method instead of
multiple
- **Clearer naming**: `SEED_FROM` better describes the source of seed
data
- **Easier maintenance**: Fewer configuration paths to test and document
- **Consistent patterns**: Aligns with other environment-variable-only
configuration
All existing functionality is preserved while providing a cleaner, more
maintainable configuration interface.
