- add the get_column_info custom tool for the ibmi-mcp-server and
relocate its --tools path from a hardcoded absolute path into the
version-controlled tree via {env:HOME} interpolation
- reorder permission rules so "rm -rf *" (deny) is no longer shadowed
by "rm *" (ask); last-match-wins now resolves rm -rf to deny
- add allow rules for the Python toolchain (unittest, py_compile,
venv activation, ruff check/format)
- rename plugin/ to plugins/ to match the documented plural convention
- commit package.json and package-lock.json so the ibmi-gate plugin
resolves @opencode-ai/plugin on a fresh stow
- correct the README opencode directory description

Gate the ibmi-mcp-server on its required environment variables.
|
|
|
|
opencode's config schema types `mcp.<name>.enabled` as a static boolean and
|
|
only interpolates `{env:VAR}` for string values (headers, environment
|
|
entries), never for the `enabled` flag. Conditionally enabling a server is
|
|
therefore not expressible in opencode.jsonc alone.
|
|
|
|
This plugin uses the `config` hook, which runs once at startup with the live
|
|
merged config (before MCP servers spawn), to flip `ibmi-server.enabled` to
|
|
`true` only when every required credential is present. The config keeps
|
|
`enabled: false` as a fallback default, so the server stays off if this
|
|
plugin fails to load.
