## The problem

- A required field, renamed tool or response shape changes while a consumer still relies on the earlier contract.

## Simpler alternatives

- Use provider-supported SDKs and native connectors when they fit. Combine contract review with real consumer, identity and failure tests; static validation alone cannot release an integration.

## Inputs

- Before and after API schemas or complete MCP catalogs
- Representative valid and invalid payloads
- Consumer dependencies, versions and authentication requirements

## Delivery sequence

- Validate representative payloads against the intended schema.
- Compare before and after contracts with consumers identified.
- Retain findings and negative cases in the local kit or private CI.
- Test live authentication and execution separately, with versioning and rollback.

## Acceptance

- Incomplete MCP catalogs are not treated as confirmed removals.
- Schema success is separate from integration success.
- Compatibility exceptions have an owner and consumer impact.

## Measure

- Compatibility findings and affected consumers
- Rejected invalid payloads and incorrect grants
- Release failures and rollback effort

## Full cost consideration

- Include consumer tests, authentication, rollout, documentation and maintenance. API and MCP access belong to the underlying product or agreed integration, not an invented second generic access fee.

## Tools available now

- Inspect API and payload contracts: https://elkwai.com/api-mcp-validation-tools.html
- Compare complete MCP catalogs: https://elkwai.com/mcp-contract-diff.html

Tools do not automatically transfer data or execute a production integration.

## Separate buying paths

- Developer Assurance Kit: $79 one time. https://elkwai.com/developer-assurance-kit
  Kit 1.1.0 does not include every free analyzer, model calls, hosted CI or a security certification.
- Custom applications and automation: Written project quote. https://elkwai.com/working-together?need=software&mode=project#offer-finder
  Ownership, integration, hosting and support are separately stated in the scope.
