Sigma shipped three overlapping ways to operate a remote server: the
embedded MCP server, sigma-cli, and the sigma-api-operator skill. All
three wrapped the same HTTP API, yet each covered a different subset:
user CRUD existed only in the CLI, system-* only in MCP, and builders,
daemons, webhooks, validators, code repositories and tokens were
reachable only through raw HTTP. MCP was disabled by default and still
carried 1246 lines of production code plus 606 lines of tests to
maintain that partially overlapping surface.
Keep two surfaces instead: sigma-cli for execution and the skill for
API discovery.
- delete pkg/server/mcp and its mcp-go dependency, which also drops the
jsonschema-go, jsonschema/v6 and uritemplate/v3 transitives
- drop ConfigurationMCP, its defaults and the authz/audit skipper
bypasses that existed only to let the MCP endpoint bypass both
- remove the mcp section from conf/config*.yaml, docs/configuration.md,
and the Helm chart values and configmap
- replace docs/mcp.md with docs/cli.md covering sigma-cli login, global
flags, per-resource commands, jq composition and agent usage
- make sigma-cli the preferred path in the sigma-api-operator skill and
rebuild its examples around the resources the CLI does not wrap yet,
using the paths and request schemas from swagger.yaml
Lint was already red on dev for an unrelated reason: golangci-lint
v2.13.0 vendors golang.org/x/tools v0.49.0, which only decodes export
data version 4, so every import of a Go 1.27.2 standard library package
failed typecheck with "export data version 5 is greater than maximum
supported version 4". Bump to v2.15.0 (x/tools v0.52.0) and fix the two
modernize findings it reports for Go 1.27's strings.CutLast.
- .github/workflows/lint.yml: golangci-lint v2.13.0 -> v2.15.0, and
document the export data constraint next to the pin
- pkg/authz/resolver.go, pkg/logger/logger.go: replace LastIndex slicing
with strings.CutLast
- bump github.com/docker/cli v29.9.0 -> v29.9.1
BREAKING CHANGE: the `mcp` configuration section and the /api/v1/mcp
endpoint are gone. Use sigma-cli or the REST API for automation.

Replace the codecov/codecov-action step with coverallsapp/github-action,
using COVERALLS_REPO_TOKEN and the golang format for the Go coverprofiles
emitted by `go test -coverprofile`. Update the README badges and the CI
workflow notes so no references to Codecov remain.
Verification:
- Ruby YAML parse of .github/workflows/test.yml
Replace the old PNG architecture diagram with an SVG version, update both English and Chinese README files to use the new local SVG asset and add explanatory text for the architecture diagram.
Add the complete tools/demo-server directory with docker compose configs,
sample scripts, grafana dashboards, prometheus configs, and documentation.
Also update README links to point to the local demo server directory.
Switch the Docker Compose stack from MySQL and Minio to PostgreSQL and rs3,
with the compose-specific configuration updated to use PostgreSQL and the rs3
S3 endpoint.
Adapt code for upgraded resty and GitLab client APIs, including the renamed
response parsing option and int64 pagination and ID fields.
Also refresh agent guidance and the Chinese README automation notes.
Verification:
docker compose -f compose.yml config
ruby -e 'require "yaml"; YAML.load_file("conf/config-compose.yaml"); YAML.load_file("compose.yml"); puts "yaml ok"'
