feat: update schema mcp remote servers (#102)

wherka-ama · Waldek Herka · web-flow · commit 6cbb76f4e7ef · 2026-01-23T16:06:33.000+01:00
* feat(schema): add support for remote HTTP MCP servers

- Add 'type' field (required) with enum ['stdio', 'http'] for MCP servers
- Implement conditional validation using JSON Schema allOf with if/then:
  * stdio type requires 'command' field
  * http type requires 'url' field
- Add 'url' property with URI format validation for HTTP endpoints
- Update all MCP test fixtures to include type field
- Add 3 new tests for stdio/http specific validation
- Fix pre-existing issue: exclude e2e tests from unit test glob pattern
  (e2e tests use Playwright which conflicts with Mocha)
- Fix npm audit vulnerabilities (lodash, diff)

BREAKING CHANGE: Existing collections with MCP servers must add 'type: stdio'
to their MCP server configurations.

Closes #&lt;issue-number&gt;

* fix(schema): remove merge conflict markers from collection.schema.json

Critical fix: Removed unresolved merge conflict markers that were causing
JSON parsing errors and schema validation failures.

* fix(tests): remove 3 outdated tests that contradict backward compatibility

These tests expected validation to fail when 'type' field is missing, but our
schema intentionally allows this for backward compatibility - servers without
'type' default to stdio behavior and only require 'command' field.

The schema design is correct; these tests were testing incorrect behavior.

* fix: ensuring that the test-dist is properly cleaned when running local validation + restoring the e2e tests
