McpEssentials.MongoDB is specified and is not in this repository yet. Use Entity Framework Core if you already map Mongo through EF, or wait for this package for a native collection and change streams.

When it ships

Document hosts that already run MongoDB and want a mcpTasks collection with change streams for elicitation.

Until then

Stay on Entity Framework Core if the host already maps Mongo through EF.

​
Intended how-to

1

Add the package

Add McpEssentials.MongoDB.
2

Create the collection

Collection mcpTasks, unique index on taskId, compound index { ownerUserId: 1, taskId: 1 }.
3

Compare-and-swap

findOneAndUpdate filtered on current status.
4

Register the store

Singleton, same current-user factory as Authenticated tasks.

​
Events

Change streams on the collection, filtered to input-request updates. Subscribers raise InputResponseReceived.

​
TTL

TTL index on the discard stamp (DiscardAfter / CreatedAt + 2×TimeToLive).

Entity Framework Core
