* fix(release-pr): sync bumped Chart.yaml to kubeshark.github.io
The release-pr target was switching back to master (and pulling)
BEFORE copying helm-chart/ into ../kubeshark.github.io/charts/chart.
That reverted the working tree to the pre-bump Chart.yaml, so the
kubeshark.github.io PR shipped the previous version and the
chart-releaser action failed trying to recreate an existing tag.
Copy the bumped chart from the release/vX.Y.Z working tree, then
switch kubeshark back to master at the end of the target.
Also consolidate iterative robustness improvements: VERSION
validation, idempotent sibling-repo tagging, idempotent branch /
commit / push / PR creation, and a "nothing to commit" guard so
reruns of release-pr do not fail.
* refactor(release): split release-pr into three rerunnable targets
Before, release-pr did three things in one recipe: tag sibling
repos, create the kubeshark release PR, and create the helm chart
PR. If any step failed, the whole target had to be rerun, even for
the parts that had already succeeded, and some sub-steps (like
tagging worker/hub/front after a docker-image-only rebuild) had no
standalone entry point.
Split into:
- release-siblings : tag worker, hub, front
- release-pr-kubeshark : bump Chart.yaml, build, open kubeshark PR
- release-pr-helm : sync chart to kubeshark.github.io, open helm PR
- release-pr : orchestrates all three in order
Each is idempotent and can be rerun independently. release-siblings
is now the canonical entry point for tagging sibling repos when
refreshing docker images without a full release.
release-pr-helm checks out release/v$(VERSION) (fetching from origin
if absent) before copying helm-chart/, so it has the bumped Chart.yaml
regardless of whether it runs right after release-pr-kubeshark or
days later in a separate invocation.
A shared _release-check-version prerequisite validates VERSION once
per target invocation.
* fix(release): make branch creation and push truly idempotent
Delete and recreate local release/helm branches instead of conditionally
checking out, and use --force-with-lease push to handle local/remote
divergence on reruns.

* Add MCP (Model Context Protocol) server command
Implement `kubeshark mcp` command that runs an MCP server over stdio,
enabling AI assistants to query Kubeshark's network visibility data.
Features:
- MCP protocol implementation (JSON-RPC 2.0 over stdio)
- Dynamic tool discovery from Hub's /api/mcp endpoint
- Local cluster management tools (check_kubeshark_status, start_kubeshark, stop_kubeshark)
- --url flag for direct connection to existing Kubeshark deployment
- --kubeconfig flag for proxy mode with kubectl
- --allow-destructive flag to enable start/stop operations (safe by default)
- --list-tools flag to display available tools
- --mcp-config flag to generate MCP client configuration
- 5-minute cache TTL for Hub tools/prompts
- Prompts for common analysis tasks
* Address code review comments for MCP implementation
- Add 30s timeout to HTTP client to prevent hanging requests
- Add scanner.Err() check after stdin processing loop
- Close HTTP response bodies to prevent resource leaks
- Add goroutine to wait on started process to prevent zombies
- Simplify polling loop by removing ineffective context check
- Advertise check_kubeshark_status in URL mode (was callable but hidden)
- Update documentation to clarify URL mode only disables start/stop
* Fix lint errors in mcpRunner.go
- Use type conversion instead of struct literals for hubMCPTool -> mcpTool
and hubMCPPromptArg -> mcpPromptArg (S1016 gosimple)
- Lowercase error string to follow Go conventions (ST1005 staticcheck)

* Add MCP server unit tests
Comprehensive unit tests for the MCP server implementation:
- Protocol tests (initialize, tools/list, tools/call, prompts/list, prompts/get)
- Tool tests (check_kubeshark_status, start_kubeshark, stop_kubeshark)
- Hub integration tests (tool fetching, caching, prompt handling)
- Error handling tests
- Edge case tests
* Fix MCP unit tests to use correct /tools/call endpoint
- Update all Hub tool tests to use POST /tools/call endpoint instead
of individual paths like /workloads, /calls, /stats
- Verify arguments in POST body instead of URL query parameters
- Add newMockHubHandler helper for proper Hub endpoint mocking
- Split TestMCP_ToolsList into three tests:
- TestMCP_ToolsList_CLIOnly: Tests without Hub backend
- TestMCP_ToolsList_WithDestructive: Tests with destructive flag
- TestMCP_ToolsList_WithHubBackend: Tests with mock Hub providing tools
- Fix TestMCP_FullConversation to mock Hub MCP endpoint correctly
- Rename URL encoding tests for clarity
- All tests now correctly reflect the implementation

* Add MCP integration test framework
Add integration tests that run against a real Kubernetes cluster:
- MCP protocol tests (initialize, tools/list, prompts/list)
- Cluster management tests (check_kubeshark_status, start_kubeshark, stop_kubeshark)
- Full lifecycle test (check -> start -> check -> stop -> check)
- API tools tests (list_workloads, list_api_calls, get_api_stats)
Also includes:
- Makefile targets for running integration tests
- Test helper functions (startMCPSession, cleanupKubeshark, etc.)
- Documentation (README.md, TEMPLATE.md, ISSUE_TEMPLATE.md)
* Address review comments on integration tests
Makefile:
- Use unique temporary files (mktemp) instead of shared /tmp/integration-test.log
to prevent race conditions when multiple test targets run concurrently
- Remove redundant test-integration-verbose target (test-integration already uses -v)
- Add cleanup (rm -f) for temporary log files
integration/mcp_test.go:
- Capture stderr from MCP server for debugging failures
- Add getStderr() method to mcpSession for accessing captured stderr
- Fix potential goroutine leak by adding return statements after t.Fatalf
- Remove t.Run subtests in TestMCP_APIToolsRequireKubeshark to clarify
sequential execution with shared session
- Fix benchmark to use getKubesharkBinary helper for consistency
- Add Kubernetes cluster check to benchmark (graceful skip)
- Add proper error handling for pipe creation in benchmark
- Remove unnecessary bytes import workaround (now actually used for stderr)

Pre-built binaries and checksum files are released at GitHub Releases.
https://github.com/kubeshark/kubeshark/releases
But checksum files for windows/amd64 have the following issues.
kubeshark.exe
kubeshark_windows_amd64.sha256
- The executable file name and the checksum file name don't conform to the naming convention
- We can't verify the pre-built binaries with checksum files because the pre-built binary name is different from the actual binary name
```console
$ cat kubeshark_windows_amd64.sha256
ea8fffa952bc8047f493469d024887ed80f966c0d74cf5fb039ea12f71174629 kubeshark_windows_amd64
```
```console
$ sha256sum -c kubeshark_windows_amd64.sha256
sha256sum: kubeshark_windows_amd64: No such file or directory
kubeshark_windows_amd64: FAILED open or read
sha256sum: WARNING: 1 listed file could not be read
```
The cause of these issues is pre-built binaries were renamed after checksum files were generated.
https://github.com/kubeshark/kubeshark/blob/b125860d068f41fd7410c4ca24a88f0278b52864/Makefile#L41https://github.com/kubeshark/kubeshark/blob/b125860d068f41fd7410c4ca24a88f0278b52864/Makefile#L61
This commit resolves the issue by generating the checksum file after renaming the pre-built binary.
