## MCP tools (6)

### `list_namespaces` (~125 tokens)

List Service Bus namespaces

List the Azure Service Bus namespaces the signed-in identity can see, across all enabled subscriptions. Large tenants can hold dozens, so pass nameFilter whenever you already know roughly what you are looking for. Requires Entra ID sign-in (not available with a connection string).

Input parameters:

- `nameFilter` (string): Case-insensitive substring, or a glob when it contains "*". Examples: "payments" matches any name containing it; "billing-*" matches names starting with it; "*-prod" matches names ending with it.
- `subscriptionId` (string): Limit to one subscription.

### `list_queues` (~55 tokens)

List queues

List queues in a namespace with active, dead-letter and scheduled message counts. Use this before peeking so you know which queues have a backlog.

Input parameters:

- `namespace` (string): Service Bus namespace name. Defaults to the server namespace.

### `list_topics` (~35 tokens)

List topics

List topics in a namespace with their message counts.

Input parameters:

- `namespace` (string): Service Bus namespace name. Defaults to the server namespace.

### `list_subscriptions` (~49 tokens)

List topic subscriptions

List the subscriptions under a topic, with active and dead-letter counts.

Input parameters:

- `namespace` (string): Service Bus namespace name. Defaults to the server namespace.
- `topic` (string, required): Topic name.

### `peek_messages` (~159 tokens)

Peek messages

Peek messages from a queue, or from a topic subscription when topic and subscription are given. Peek is non-destructive: it does not lock, consume, or increment delivery count. Set fromDeadLetter to read the dead-letter queue instead of the main entity.

Input parameters:

- `count` (integer): How many messages to return.
- `fromDeadLetter` (boolean): Read the dead-letter queue.
- `fromSequence` (integer): Start at this sequence number.
- `namespace` (string): Service Bus namespace name. Defaults to the server namespace.
- `queue` (string): Queue name. Omit when using topic + subscription.
- `subscription` (string): Subscription name, requires topic.
- `topic` (string): Topic name, when reading a subscription.

### `search_messages` (~206 tokens)

Search messages

Scan a queue or subscription for messages matching a body substring, message id, or subject. Non-destructive. Scanning is bounded by maxMessages and by a server-side timeout, so on a deep backlog prefer a narrow filter. Returns matching messages with their sequence numbers.

Input parameters:

- `bodyFilter` (string): Case-insensitive substring to find in the body.
- `fromDeadLetter` (boolean): Search the dead-letter queue.
- `maxMatches` (integer): Stop after this many matches.
- `maxMessages` (integer): Cap on messages scanned.
- `messageIdFilter` (string): Exact message id to match.
- `namespace` (string): Service Bus namespace name. Defaults to the server namespace.
- `queue` (string): Queue name. Omit when using topic + subscription.
- `subjectFilter` (string): Subject (label) to match.
- `subscription` (string): Subscription name, requires topic.
- `topic` (string): Topic name, when searching a subscription.
