MCP and assistants

What breaks when you run MCP servers in production?

LinkedBoost editorial Reviewed

Production MCP workflows need reliable tool selection, authentication, state management and recovery from uncertain writes. The protocol provides interfaces, not an application's delivery guarantees. Treat a timeout after a write as an unknown result until reconciled, expose account and job state clearly, and test the client's real approval and reconnection behavior.

Tool discovery needs a task boundary

MCP defines how clients discover and call tools. Name operations clearly and describe the inputs, outputs and side effects. Overlapping descriptions make it harder for a client to distinguish a conversation reply from a new message.

Test selection with representative tasks, missing fields and wrong-account scenarios. There is no universal maximum tool count that ensures good selection. Context cost also depends on whether a client loads all definitions or discovers tools on demand.

Separate connector auth from the linked service

A client may reach an MCP server while its workspace authorization is expired, or authenticate successfully while the downstream LinkedIn account is disconnected. Report those conditions separately so the operator knows which connection needs attention.

For HTTP-based MCP authorization, follow the negotiated protocol version and its authorization requirements. Do not treat every error as an expired token or keep retrying a denied action. Use a clear path to reauthenticate and then perform a read.

Keep business state inspectable outside chat

Store a sequence or long-running job in the application, with an identifier, status, target and timestamps. A new conversation should be able to inspect that state without relying on the previous assistant's narrative.

Return bounded results and pagination where needed. Separate prepared, queued, running, completed, failed and unknown states so an assistant cannot reasonably summarize every accepted request as a completed action.

Reconcile a write before retrying it

A request can complete downstream before the response is lost. Use idempotency where supported, retain the operation identity, and inspect the result before retrying. A read retry is not the same decision as another invitation or message.

For a queued action, check whether cancellation reaches work already dispatched. Test pause, reconnect and replay cases using a controlled environment. These are engineering recommendations, not a claim that every named safeguard is implemented by LinkedBoost.

Make verification part of the workflow

For LinkedBoost, the public tool catalogue identifies workspace overview, connection checks, sequence inspection and activity records. Use those reads to inspect the intended workspace and relevant operation before stating an outcome.

A useful first evaluation is a read, a draft, an inspected authorization boundary and a checked result. Do not assume human approval before each scheduled step merely because enrollment required approval.

Frequently asked questions

How many tools are too many?

There is no universal threshold. Evaluate selection accuracy and context cost on the actual client and task set.

Does MCP prevent duplicate sends?

No. Application-level identity, idempotency where available, result inspection and retry policy must address that behavior.

Does closing a chat stop a sequence?

Do not assume so. A server may continue scheduled work. Inspect and pause it through the application's controls.

Is a tool returning success proof of delivery?

Only if that result represents the completed downstream action. An accepted or queued request is a different state.
