```

Defined in: [packages/query-core/src/utils.ts:237](https://github.com/TanStack/query/blob/main/packages/query-core/src/utils.ts#L237)

Checks whether a mutation matches the given [MutationFilters](../interfaces/MutationFilters.md).
Every filter that is specified must match; filters that are left unspecified are ignored.
If a `mutationKey` filter is provided but the mutation has no `mutationKey` of its own, it does not match.

## Parameters

### filters

[`MutationFilters`](../interfaces/MutationFilters.md)

### mutation

[`Mutation`](../classes/Mutation.md)\<`any`, `any`\>

## Returns

`boolean`

## Example

```ts
const mutationCache = queryClient.getMutationCache()

const matchingMutations = mutationCache
  .getAll()
  .filter((mutation) => matchMutation({ mutationKey: ['addPost'] }, mutation))
```
