Unit Expert MCP

Minimal Streamable HTTP MCP server for PlayMCP.

PlayMCP Settings

MCP 이름: Unit Expert(단위전문가)
MCP 식별자: unitExpert
MCP URL: https://unit-expert-mcp.onrender.com/mcp
인증: 없음

Related MCP server: Unit Converter AI MCP Server

HTTP Endpoints

GET  /
GET  /healthz
POST /mcp
GET  /mcp
GET  /scenario
POST /scenario

POST /mcp expects JSON-RPC with:

Accept: application/json, text/event-stream
Content-Type: application/json

Tools

  • convert_length

  • convert_weight

  • convert_temperature

  • convert_area

  • convert_volume

  • list_supported_units

Scenario Control

Open /scenario in a browser to set the server-wide default scenario. The page also shows a live /mcp response preview for the selected scenario.

Use X-MCP-Test-Scenario to override the server-wide state for one request. Omit it for the currently selected scenario.

The selected scenario is stored in process memory, so it resets to ok after a server restart or redeploy.

X-MCP-Test-Scenario: duplicate-tool-name

Run Locally

PYTHONPATH=src PORT=8000 python -m unit_expert_mcp.server

Smoke test:

curl -i -X POST http://localhost:8000/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -H 'MCP-Protocol-Version: 2025-03-26' \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"curl","version":"1.0"}}}'

Official SDK 2026 Baseline

The existing unit_expert_mcp.server implementation is the fault-injection server used for 2025/legacy and intentionally invalid scenarios. For a clean 2026-07-28 baseline backed by the official MCP Python SDK, run the separate entrypoint:

pip install ".[sdk2026]"
PYTHONPATH=src PORT=8000 python -m unit_expert_mcp.sdk_2026_server

This starts a Streamable HTTP MCP endpoint at /mcp using the SDK's ASGI app. It exposes the same six Unit Expert tools, but does not implement the scenario UI or malformed-response cases.

Expected Render endpoint:

https://unit-expert-mcp-2026.onrender.com/mcp

Docker:

docker build -f Dockerfile.sdk2026 -t unit-expert-mcp-sdk2026 .
docker run --rm -p 8000:8000 unit-expert-mcp-sdk2026

Test

PYTHONPATH=src python3 -m unittest discover -s tests -p 'test*.py'
