CAPABILITY PROFILE

What the AgentMail integration exposes

The AgentMail Agent App exposes 102 provider-backed actions for communication and productivity work. Its current contract lets an authorized agent fetch multiple messages from a specific agentmail inbox by message id, create an agentmail api key, and delete an agentmail api key. These operations are called through Working Machines as typed capabilities rather than through browser navigation or copied UI steps.

A connection uses API key. Before execution, the agent can inspect the selected action, its required fields, declared scopes, and expected output contract. Provider credentials remain inside the Working Machines runtime; the calling agent receives the capability and its structured result, not the underlying secret.

For reliable operation, start with the narrowest action that satisfies the task, resolve stable provider identifiers before changing state, and validate the returned object or status after execution. Availability still depends on the connected AgentMail account, granted provider permissions, workspace policy, region, plan, and upstream API behavior.

PROVIDER-SPECIFIC WORKFLOWS

Jobs this Agent App can support

Inspect Batch Get Messages

Fetch multiple messages from a specific AgentMail inbox by message ID. Use this as a bounded discovery step, retain the returned identifier, and avoid expanding the read beyond the task's stated scope.

batch_get_messages

Control Create Api Key

Create an AgentMail API key. Resolve the target first, present material changes for confirmation, and make retries idempotent where the provider supports it.

create_api_key

Verify with Create Api Key

Create an AgentMail API key. Compare the returned provider state with the intended outcome and preserve stable IDs or canonical links in the run record.

create_api_key

SAFETY BOUNDARY

Operate AgentMail with explicit limits

  • Authorize AgentMail with API key and grant only the provider access required by the selected actions.
  • 40 actions are change-capable by name. Confirm the target identity and material parameters before allowing a write.
  • Treat `delete_api_key`, `delete_domain`, and `delete_draft` as high-impact operations and require an explicit approval boundary.
  • No provider scope string is declared on the sampled actions. Verify the connected account's actual permissions in AgentMail rather than assuming unrestricted access.
  • After a call, inspect the structured result and execution record before reporting that the AgentMail task completed successfully.

CONNECTION MODEL

API key

AgentMail API key used with the Authorization Bearer header. Create it in the AgentMail Console API Keys section.

Working Machines stores provider credentials behind the execution boundary. An agent can use an authorized connection identity, but catalog discovery alone does not reveal OAuth tokens, API keys, or provider secrets.
