Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@iris-weather-mcp get the 5-day forecast for Austin, Texas"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
The weather plugin's forecast tool as a standalone MCP server process, run through the
harness's signed MCP bridge, with no import of iris_harness in the plugin process.
This is the experiment of
iris-harness#82: comparison data for
the trust-ladder / isolation question, not a production proposal. The server itself is
standalone; the comparison tests are built against iris_harness's stable tier where possible and
record in docs/GAPS.md (GAP-M1) the places where they had to import non-stable modules (the
MCP bridge and its signing package), because the stable tier offers no MCP surface.
src/iris_weather_mcp/: the server (official mcp SDK, stdio). Dependencies: mcp, httpx.
tests/: the comparison suite. It runs in a SECOND venv that holds the harness wheel and
spawns the server with the first venv's interpreter. Fault fixtures are stdlib-only servers
in tests/servers/; the upstream is a loopback stub.
docs/COMPARISON.md: in-process vs MCP, per graduation property, with evidence.
docs/GAPS.md: what the bridge and SDK could not do, as precise findings.
scripts/ci_local.sh: the local gate (two fresh venvs, lint, isolation proof, tests).
The in-process plugin (../iris-weather-plugin) is the control arm and is not modified.
iris-harness is not on a package index yet (iris-harness#108). scripts/ci_local.sh is the
gate: it builds two throwaway venvs (the server's, with no harness; the test host's, with an
iris-harness wheel built from the clone given by IRIS_HARNESS_CLONE, default
../iris-harness, or a prebuilt wheel in IRIS_WHEEL_DIR), lints, scans the server source,
and runs the suite. The control arm (tests/test_compare.py) imports a sibling checkout of
iris-weather-plugin at
../iris-weather-plugin; it is skipped, loudly, when that is absent. There is no hosted CI for
this repository.
