[mavogel]

Checks

• I have searched github.com/aws/amazon-q-developer-cli/issues and there are no duplicates of my issue
• I have run q doctor in the affected terminal session
• I have run q restart and replicated the issue again

Operating system

OSX

Expected behaviour

MCP client support for elicitation feature per MCP spec should work as described in #2898 (merged)

something similar to

[default] > Use the MathCalculator tool for values 5 and 5

> I'll use the MathCalculator tool with the values 5 and 5.


🛠️  Using tool: MathCalculator from mcp server FooServer
 ⋮ 
 ● Running MathCalculator with the param:
 ⋮  {
 ⋮    "firstNumber": 5,
 ⋮    "secondNumber": 5
 ⋮  }


MCP server FooServer is requesting information
Choose the mathematical operation to perform on 5 and 5:

  operation: multiplication        <---------------------- THE VALUE HERE IS INPUT FROM THE USER

Submit this information? [y/n/c]: y

 ⋮ 
 ● Completed in 5.913s


> The calculation is complete! The result of 5 × 5 = 25.

BUT the message MCP server FooServer is requesting information never shows up.

Actual behaviour

Eliciation does not work, aka times out.

[mcp-test-developer] 12% > register a user

✓ 1 of 1 hooks finished in 0.09 s



🛠️  Using tool: register_user from mcp server local
 ⋮ 
 ● Running register_user with the param:
 ⋮  {}

Allow this action? Use 't' to trust (always allow) this tool for the session. [y/n/t]:

[mcp-test-developer] 12% > y

 ⋮ 
 ● Execution failed after 15.2s:
Transport send error: Transport [rmcp::transport::worker::WorkerTransport<rmcp::transport::streamable_http_client::StreamableHttpClientWorker<reqwest::async_impl::client::Client>>] error: Client error: error sending request for url (http://localhost:3000/mcp)

Additionally in the vscode Q Developer extension it also times out.

Steps to reproduce

Using example https://github.com/modelcontextprotocol/typescript-sdk/blob/1.22.0/src/examples/server/elicitationExample.ts

Steps

git clone git@github.com:modelcontextprotocol/typescript-sdk.git
cd typescript-sdk
npx tsx src/examples/server/elicitationExample.ts
# runs on localhost:3000

with the agent cfg at ~/.aws/amazonq/cli-agents/mcp-test-dev-agent.json

{
  "$schema": "https://raw.githubusercontent.com/aws/amazon-q-developer-cli/refs/heads/main/schemas/agent-v1.json",
  "name": "mcp-test-developer",
  "description": "Local agent for testing mcp",
  "mcpServers": {
    "local": {
      "type": "http",
      "url": "http://localhost:3000/mcp",
      "timeout": 15000
    }
  },
  "tools": [
    "fs_read",
    "fs_write",
    "execute_bash",
    "@local"
  ],
  "allowedTools": [
    "fs_read",
    "fs_write"
  ],
  "resources": [
    "file://README.md",
    "file://**/AmazonQ.md",
    "file://.amazonq/rules/**/*.md"
  ],
  "useLegacyMcpJson": true
}

The server works correctly as I could verify it with Github Copilot with .vscode/mcp.json

{
	"servers": {
		"local": {
			"type": "http",
			"url": "http://localhost:3000/mcp"
		}
	},
	"inputs": []
}

and output
