MCP Client with Elicitation Support

A simple CLI MCP client that demonstrates elicitation handling.

Setup

npm install

Usage

stdio mode (spawns computeruse-mcp-agent)

npm run start:stdio

This will:

1. Spawn computeruse-mcp-agent via npx as a child process
2. Connect via stdio transport
3. List available tools
4. Let you call tools interactively

To use a local build instead of the npm package:

LOCAL_BUILD=1 npm run start:stdio

HTTP mode (connects to running server)

npm run start:http [port]

Connects to a computeruse-mcp-agent running in HTTP mode (default port: 8080).

When elicitation is triggered

When the server sends an elicitation/create request, the client will:

1. Display the message and schema
2. Prompt you to fill in each field
3. Let you accept, decline, or cancel
4. Send the response back to the server

Current Status

Note: As of Dec 2025, the computeruse-mcp-agent has elicitation support but no tools currently trigger elicitation. This client is ready for when tools start using peer.elicit().

To test elicitation, you would need to:

1. Modify a tool in computeruse-mcp-agent to call elicit_with_fallback()
2. Or create a test tool that triggers elicitation
