A2A Agent Card · Nylas

Nylas

Agent-callable access to email, calendar and contacts across Gmail, Outlook, Exchange, iCloud, Yahoo and any IMAP provider. A grant represents one authenticated mailbox and calendar; Agent Accounts provision a Nylas-hosted mailbox and calendar for an autonomous agent without an OAuth flow.

⚠ Agent card, not A2A. Nylas serves a machine-readable agent manifest at the A2A discovery path, but it fails a structural check in the A2A 1.0.0 AgentCard object. It is an agent card in spirit rather than in schema — useful for discovery, but an A2A client cannot assume it will parse.

Discovery

An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.

View the captured card. Providers change what they serve; if this card has moved or changed shape, the provider profile carries the current state as of the last build.

Work with this as data

Every agent card here is available over the APIs.io API and to AI agents over MCP. A2A Agent Cards is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
