A client handoff is successful when someone other than the developer can operate that workflow, identify a failure and know who owns the next action. For an agency, that distinction affects support time and client trust. Start with a written statement of the job: which system the agent reads or changes, which users can invoke it, and what a correct result looks like. Avoid a vague promise to connect every business application. Choose an outcome that can be demonstrated on agreed test data. ## Agree on ownership before deployment Document who owns the source repository, hosting account, DNS name, upstream subscriptions and production credentials. Identify the person who approves a release and the person who receives an incident report. If you operate infrastructure on the client’s behalf, agree on export and offboarding before launch. A custom domain can make the connection recognizable, but it also introduces certificate renewal and DNS responsibilities. Do not remove the old connection until the replacement has been verified. Keep a record of the source revision and the required runtime configuration so future maintenance is not dependent on one developer’s laptop. ## Separate access for people and systems Use separate consumer credentials for different integrations and environments. Give a test client only the calls needed for acceptance, and revoke that access when the test ends. A tool that reads a project list and a tool that deletes a project should not be treated as equivalent permissions. Also document the upstream identity used by the server. Separate gateway keys do not automatically create separate upstream accounts or customer-specific data boundaries. If individual users must authorize their own business accounts, evaluate an end-user authorization design rather than sharing an agency-wide upstream secret. ## Create an acceptance record Record evidence for initialization, tool discovery and one representative successful call. Add a denied-tool check, a revoked-key check and a rate-limit check where supported. Explain which failures are expected and how they appear in the client. Test a restart or update in a safe environment, then verify that the connection still works. Acceptance evidence should identify the revision, client version, date and result without embedding credentials or sensitive tool arguments. A checklist with observable results is more useful than a blanket statement that the integration is production-ready. ## Make incidents diagnosable Define what the operator can observe: request IDs, status codes, latency, runtime health and deployment errors. Decide which data should not be retained, particularly business payloads and secrets. Set expectations about response times and escalation rather than implying an around-the-clock service that nobody staffs. When a call fails, the first question is whether the problem is client setup, gateway access, runtime execution or the upstream API. Keep enough evidence to distinguish those layers. Replaying a write-capable tool can duplicate an action, so a retry is not always a harmless diagnostic step. ## Price the work that continues after launch Recurring service work can include release reviews, credential maintenance, usage review and incident triage. Price that scope explicitly instead of hiding unlimited engineering inside a small hosting fee. Separate a one-time migration or setup charge from monthly recurring service revenue. MCP Ops can support an initial guided workflow using its current repository import, API-key controls, tool playground and per-MCP usage views. It is not a substitute for unimplemented OAuth, enterprise identity or a contractual uptime guarantee. Start with one supported client integration, document the handoff and expand only after the client repeatedly gets value from it. ## References and further reading - [MCP authorization specification](https://modelcontextprotocol.io/specification/2025-11-25/basic/authorization) - [OpenTelemetry signals](https://opentelemetry.io/docs/concepts/signals/) Check the fit for your MCP before deployment.
