Agent-to-Agent
Open in CMSThe Agent-to-Agent screen lets other AI agents reach your agent over a secure link (the A2A protocol), separate from your public chat page. Found in the agent sidebar under Channels → Agent-to-Agent.
This page is the inbound direction: other agents calling yours. To connect agents that your agent can call for help, use Tools → Other Agents; the info box at the top of the page links there too.
Reachable by Other Agents
| Reachable by other agents | Off by default. Separate from making your chat page public. Everything below appears only while this is on. |
| Share (agent name) | The agent's link (its agent card URL), with a copy button. Send it to whoever wants to connect their agent. They also need an API key from you, which you create under Manage API keys (Channels → Agent Keys). The link starts working once the agent is published. Before the agent is saved, it reads "Save this agent first to get its link." |
Agent Card Tab
An agent card is like a business card for your agent: it tells other agents who it is, what it is good at and how to reach it. The info icon next to the heading explains this.
| Auto-fill with AI | Generates a description, topics and example questions for you. If any of them are already filled in, it asks for confirmation first, because it replaces them. Shows Generating… while it runs. |
| Suggestions | When some fields are still empty, a banner offers questions, topics and a description based on the agent's profile. Add suggestions fills them in for you to edit; Dismiss hides the banner. |
| Example questions (agent name) can answer | One question per line. Other agents read these to learn what to send here; real questions your agent answers well work best. Edit them as a list (with Add question and a remove button per question) or as free text. While there are none, a warning on the field and on the tab says other agents cannot find your agent. |
| Topics (optional) | Type a topic and press Enter, for example billing, refunds or account-support. Topics help other agents find your agent. |
| Description (optional) | What other agents see when they discover your agent. Starts from its mission; edit as needed. |
| Advanced technical details | Click to expand. Shows the Protocol (A2A, JSON-RPC 2.0), Streaming (off: text only, one reply at a time) and the Endpoint URL with a copy button. Other agents sign in with a key you give them, and your agent answers in text only for now. |
Tool Access Tab
Decides which of your agent's tools other agents may use. Other agents can always ask your agent questions; everything else is off until you allow it. Turn on only what you would be comfortable letting a stranger's agent use.
| What other agents can use | The heading, with a count of how many tools are allowed out of the total. |
| Search tools | Filters the list by tool name. |
| All · Allowed · Not allowed | Shows all tools, only the allowed ones, or only the ones that are not allowed. |
| Tool groups | Built-in (Web search, Web page reader), Your custom tools, MCP tools (grouped by server) and Plugins, each with its own count. Click a group to collapse or expand it. Use the switch on a tool to allow or block it. |
| Always off | Tools you cannot change. Knowledge base is marked Always on. Hand over to a person is always off, because there is no person at the other end of an agent call. Tools that call your other agents are always off, so a caller cannot reach your other agents through this one. |
| No tools yet | When the agent has no tools, a note says you can choose here once you add some. |
Save
| Save all changes | In the bar at the bottom of the page. Asks for confirmation, then saves both tabs and the switch together. |
