* Update README with new structure and AI focus
* Update AI section: AI-Powered Root Cause Analysis with agents
* updated links
* added an image to the API context
* some fixes to the readme
* Remove TODO comments - using real images
The Hub API expects 'name' field but the MCP server was sending 'tool'.
This caused all Hub-forwarded tools (list_l4_flows, get_l4_flow_summary,
list_api_calls, etc.) to fail with 'tool name is required' error.
Local tools like check_kubeshark_status were unaffected as they don't
call the Hub API.
* Add MCP Registry support with MCPB package format
- Update release workflow to create .mcpb artifacts for MCP Registry
- Update server.json to use MCPB registry type with GitHub namespace
- Use io.github.kubeshark/mcp namespace for GitHub authentication
- Add SHA256 placeholders (to be updated after first release)
* Add automated MCP Registry publishing to release workflow
- Add workflow_dispatch trigger with dry_run option for testing
- Add mcp-publish job that runs after release completes
- Generate server.json dynamically with correct version and SHA256 hashes
- Install and run mcp-publisher automatically
- Update static server.json to reference file with placeholders
- Add MCP Registry section to README
The release workflow now automatically publishes to the MCP Registry
when a new version is tagged. No manual steps required.
* Refactor: Extract MCP publishing to separate workflow
- Create mcp-publish.yml that triggers on release:published
- Simplify release.yml to focus on building and releasing
- MCP workflow has its own workflow_dispatch for testing
- Cleaner separation of concerns
* Address PR review feedback
- Update actions/checkout to v4
- Add OIDC permissions for MCP Registry authentication
- Change trigger from release:published to workflow_call
- Release workflow now calls mcp-publish after artifacts are uploaded
- Keep workflow_dispatch for manual testing
* Add mcp-publisher login step before publish
* 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)
