Glossary

Every term, one line each. For the fuller picture, see Concepts.

A2A (Agent-to-Agent)

The JSON-RPC 2.0 protocol brokers speak. Versions 0.3 (default) and 1.0differ in method name, message shape, and header.

Action

A callable capability in AgentScript (@actions.x) — an MCP tool or an A2A send — that a node is allowed to run. Auto-created when you compose an MCP server or agent.

Agent card

The A2A discovery document describing a broker and its skills; the public contract. Usually served at/.well-known/agent-card.json.

Agent Network

The published unit — one Exchange asset bundling agent-network.yaml, exchange.json, and one broker's .agent file. Contains exactly one broker.

AgentScript

MuleSoft's AgentFabric dialect for a broker's node graph, stored in a .agentfile. Builder generates it from the canvas.

Anypoint CLI v4

The command-line tool (anypoint-cli-v4) plus the agent-fabric plugin that Build & Publish shells out to for build/publish/deploy.

Artifact

A named output a task produces, surfaced in Tracer's Task story.

Broker

The deployed, LLM-driven agent runtime that receives A2A requests and runs its graph. A network's only front door.

Business group

The Anypoint org scope selected in the left sidebar; governs which assets, environments, and gateways you see. Passed to the CLI as --organization.

Connection

A context.connections entry in the YAML that a composed Exchange asset becomes; targeted by actions and LLM bindings.

Context / contextId

The id grouping multiple tasks into one conversation.

Echo

The graph node kind that sends a response to the client. Terminal on a Completed/Failed/Canceled/Rejected status; otherwise must transition onward.

Enhanced Log Search

The Anypoint entitlement (Advanced package / Titanium) that unlocks full-fidelity tracing. Without it, Tracer falls back to runtime logs.

Exchange asset / GAV

A reusable published artifact identified by groupId : assetId : version. LLMs, MCP servers, agents, policies, and networks are all Exchange assets.

Executor

A deterministic node kind — sets variables and runs actions, no LLM. Forbids slot-filling.

Gateway

A Flex Gateway used as a deployment target. For shared-space deploys you pick one gateway; the CLI derives the space.

Generator

A node kind: a single LLM call to produce text — no tools, no loop.

LLM binding

An LLM asset wired into AgentScript (@llm.x) that reasoning nodes use. On Tracer's graph, LLM nodes are design-time only.

MCP (Model Context Protocol)

The standard for agents calling external tools. An MCP server exposes named tools; a broker calls them as actions.

Object Store

Where brokers persist task state and reasoning — the source of Tracer's Task story. Keys expire (24h default TTL, 30d max).

Orchestrator

A subagent node specialized for coordinating multiple agents and MCP tools toward a goal.

Private space

A CloudHub 2.0 private space / Runtime Fabric deploy target; needs a space plus ingress and egress gateways.

Router

A deterministic branching node — routes on conditions, no LLM. Needs routes plus an otherwisetarget.

Shared space

A CloudHub 2.0 shared regional space (the Cloudhub- prefix), derived by the CLI from your chosen gateway.

Skill

A capability a broker advertises on its agent card; Tracer's Invoke rail offers skills as one-click starters.

Structured outputs

Declared outputs on a reasoning node, letting a router branch on@node.output.field instead of parsing prose.

Subagent

A node kind: a generic agent loop with a prompt and a set of actions.

Task

One A2A request/turn — the unit Tracer traces. Carries iterations, artifacts, and a terminal status.

Task story

Tracer's structured v2 view of a task — conversation history, artifacts, and state — decoded from Object Store.

Teardown

Undeploy (stop the running network) and unpublish (erase the Exchange version). Undeploy first.

Trigger

The single graph entry point that starts the flow when a message arrives. Can't be deleted; nothing transitions into it.

v1 vs v2 broker

v1 = ReAct-style reasoning loop (Tree/List views); v2 = node-graph AgentScript runtime (timeline, Task story, graph overlay). Builder authors v2.

Variables / properties

exchange.json deploy variables referenced as ${group.field}, passed to the CLI as --property name:value. Secrets re-entered each session.
