Handle interactive user input requests from MCP servers
elicitation/create. Two modes:
import {
acceptWithDefaults,
MCPClient,
type OnElicitationCallback,
} from "@mcp-use/client";
const onElicitation: OnElicitationCallback = async (params) => {
if (params.mode === "url") {
console.log(`Visit: ${params.url}`);
return { action: "accept" };
}
// Form mode — collect fields from params.requestedSchema
return acceptWithDefaults(params);
};
const client = new MCPClient(config, { onElicitation });
@mcp-use/client:
| Helper | Purpose |
|---|---|
acceptWithDefaults(params) | Accept using schema defaults |
accept(content) | Accept with user content |
decline(), cancel() | Reject or dismiss |
validate(params, content) | Client-side validation |
getDefaults, applyDefaults | Work with schema defaults |
const mcp = useMcp({
url: "http://localhost:3000/mcp",
onElicitation: (params) => acceptWithDefaults(params),
});
pendingElicitationRequests and approveElicitation / rejectElicitation.
Without an onElicitation handler, tool calls that require input will fail.
