# A2A Connector 2.0 Reference

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

Anypoint Connector for Agent2Agent (A2A) (A2A Connector) provides A2A protocol support for LLM
agents, enabling your agents to talk to other agents.

## Configurations

### Client

The application or AI system that initiates requests and consumes services offered by A2A servers.
This allows Mule apps to act as A2A brokers between non A2A “head” agents and A2A “node” agents.

protocol methods for interacting with other AI agents. This allows Mule-based agents to receive and
respond to A2A protocol-compliant requests.

## A2A Server - Get Tasks

`<a2a:get-tasks>`

Retrieves a batch of tasks from the server’s internal task store. Resolved tasks are returned in
`tasks`; task IDs that the store doesn’t have are reported in `nonExistentTaskIds`. Genuine failures
(such as a corrupt store entry, an ObjectStore IO failure, or an unexpected serialization error) are
surfaced as A2A errors rather than reported as nonexistent. This is a blocking operation because
each lookup performs synchronous IO against the underlying ObjectStore (often Object Store v2).
Lookups run sequentially on the calling thread to avoid uncontrolled fan-out against a remote,
rate-limited store. The primary use case is resolving `referenceTaskIds` on incoming A2A messages so
the agent flow has the full context of referenced tasks.

### Parameters

## A2A Server - Get Tasks By Context

`<a2a:get-tasks-by-context>`

Retrieves every task belonging to a `contextId`, oldest first, from the server’s internal task
store. A2A 1.0.0 treats a `contextId` as a conversational session that groups multiple task and
message objects, so this operation lets an agent flow recover that session by reading all tasks
recorded for the context in a single call. The full ordered task list is returned and isn’t paged,
because the underlying object store offers no ranged or cursored read: the per-context index loads
as a single entry regardless. Tasks are never truncated, because dropping tasks would give the agent
an incomplete conversation. Use the **History Length** field to bound the message history embedded
within each task. Lookups are synchronous IO against the underlying object store, resolved
sequentially to avoid uncontrolled fan-out against a remote, rate-limited store. Genuine internal
failures (such as an object store IO error or corrupt stored task JSON) are logged server-side with
full detail and surfaced as a generic A2A:INTERNAL\_ERROR. A blank or unknown `contextId` returns an
empty task list rather than an error.

## A2A Server - Send Push Notification

`<a2a:send-push-notification>`

Sends a push notification with the provided streaming event payload. This operation allows sending
asynchronous updates at various stages of a task, not just at the end. The body sent to the push URL
is the StreamResponse JSON, as specified in A2A spec section 4.3.3. This is a non-blocking operation
that uses a completion callback for asynchronous result handling.

## A2A Server - Set Task Metadata

`<a2a:set-task-metadata>`

## Sources

## A2A Server - On Async Request Listener

`<a2a:on-async-request-listener>`

Lets the agent flow customize the initial Task emitted for streaming (Send Stream Message) and
non-blocking (Send Message with `returnImmediately=true`) requests. The flow receives
MessageSendParams as the payload (with `taskId` and `contextId` as attributes) and must return a
Task, which is used to seed initial state, attach artifacts, or gate the request. Returning a
terminal or interrupted Task, or raising an error, rejects the request up front. A missing or
unparseable Task is a server-side fault: the client sees A2A:INTERNAL\_ERROR with a generic message,
while the location and parse detail are logged server-side. Push notification configuration is
handled by the [A2A Server - On Push Notification Set Listener](#PushNotificationConfigListener)
source, not this listener.

## A2A Server - Task Authorizer Listener

`<a2a:task-authorizer-listener>`

A2A Server task authorizer listener. Gates every auth-required operation before it executes. The
flow’s payload shape depends on the operation. For List Tasks, the flow receives a JSON array of
candidate `{taskId, contextId}` pairs for the current page and must return a JSON array of the
authorized subset (each entry with `taskId` and `contextId`); an empty array denies the entire page.
For other auth-required operations (Get Task, Cancel Task, Subscribe To Task, and the push
notification config Get, List, and Delete operations), the flow receives the raw JSON-RPC request
params as the payload. Successful completion of the flow authorizes the request; the returned
payload isn’t inspected. To deny a request, raise an error from the flow, which is mapped to
UNAUTHORIZED. The current operation is available on `attributes.operationName`.

### Streaming Response Attributes

In A2A Connector 1.0 and later, this represents the HTTP response attributes for A2A streaming
operations (SSE). This specialized type extends [Response Attributes](#ResponseAttributes) with
streaming-specific metadata, including information about final events received during the SSE
session. This final event information is not related to the A2A protocol final event, but the
connector’s.

<table><colgroup><col> <col> <col> <col> <col></colgroup><thead><tr><th>Field</th><th>Type</th><th>Description</th><th>Default Value</th><th>Required</th></tr></thead><tbody><tr><td><p><strong>Final Event Found</strong></p></td><td><div><div><p>Boolean</p></div></div></td><td><div><div><p>Whether a final event was found during SSE session.</p></div></div></td><td><div><div><p>false</p></div></div></td><td><div></div></td></tr><tr><td><p><strong>Status Code</strong></p></td><td><div><div><p>Number</p></div></div></td><td><div><div><p>HTTP status code of the response.</p></div></div></td><td><div></div></td><td><div><div><p>x</p></div></div></td></tr><tr><td><p><strong>Headers</strong></p></td><td><div><div><p>Object</p></div></div></td><td><div><div><p>Map of HTTP headers in the message.</p></div></div></td><td><div></div></td><td><div><div><p>x</p></div></div></td></tr><tr><td><p><strong>Reason Phrase</strong></p></td><td><div><div><p>String</p></div></div></td><td><div><div><p>HTTP reason phrase of the response.</p></div></div></td><td><div></div></td><td><div></div></td></tr></tbody></table>

### Interface

One entry under `<a2a:interfaces>`: a protocol binding that specifies a transport and a path segment
appended to the connection’s agent path for that binding. For example, with agent path `/my-agent`
and path `/rpc`, JSON-RPC is exposed at `/my-agent/rpc/`. Use
`<a2a:interface protocol="JSONRPC" path="/rpc"/>`.

<table><colgroup><col> <col> <col> <col> <col></colgroup><thead><tr><th>Field</th><th>Type</th><th>Description</th><th>Default Value</th><th>Required</th></tr></thead><tbody><tr><td><p><strong>Protocol</strong></p></td><td><div><div><p>Enumeration, one of:</p></div><div><ul><li><p>JSONRPC</p></li><li><p>HTTP_JSON</p></li></ul></div></div></td><td><div><div><p>Protocol binding (transport) that the interface uses.</p></div></div></td><td><div></div></td><td><div><div><p>x</p></div></div></td></tr><tr><td><p><strong>Path</strong></p></td><td><div><div><p>String</p></div></div></td><td><div><div><p>Path segment appended to the connection’s agent path for this binding.</p></div></div></td><td><div></div></td><td><div><div><p>x</p></div></div></td></tr></tbody></table>

### Request Attributes

In A2A Connector 1.0 and later, this represents the HTTP request attributes for an A2A incoming
request. This type encapsulates the HTTP request metadata, including query parameters and headers,
that are received as part of an A2A protocol request.
