* feat(mcp): store oversized text results as artifacts
* feat(mcp): fix doc
* fix(mcp): preserve raw MCP payload in text artifacts
* fix(mcp): avoid leaking large text when artifact persistence fails
* chore(mcp): clarify inline text limit and cover artifact edge cases
- MCPTool.Name(): append FNV-32a hash of original (unsanitized) server+tool
names whenever sanitization is lossy or total length exceeds 64 chars,
ensuring names that differ only in disallowed characters remain distinct
- ToolRegistry.Register(): emit warn log when a tool registration overwrites
an existing tool with the same name, making collisions observable
- scripts/test-docker-mcp.sh: switch shebang from #/bin/bash /Users/yuchou/Work/klook-calendar/klook-google-cal-sync/src/googlecalconversrv/bin/start.sh to # for portability on minimal distros and Nix environments
- Avoid logging sensitive cfg.Args in ConnectServer; log args_count instead
- Sanitize server/tool name components in MCPTool.Name() to ensure valid
identifiers for downstream providers (lowercase, [a-z0-9_-] only)
- Add slack as 5th MCP server example in config.example.json
- Move Dockerfile.full and docker-compose.full.yml into docker/ directory
for consistency with existing docker/Dockerfile and docker/docker-compose.yml
- Fix all Makefile docker-* targets to reference correct compose file paths
- Fix docker/docker-compose.full.yml build context (.. ) and volume paths
- Fix scripts/test-docker-mcp.sh compose file path and replace cowsay test
with actual @modelcontextprotocol/server-filesystem MCP server test
CallTool can return (nil, nil) if the underlying MCP library misbehaves.
Without a nil check, result.IsError would panic. Return an explicit error
ToolResult instead.
- Handle json.RawMessage and []byte types by direct unmarshal
- Use JSON marshal/unmarshal for struct types to preserve schema
- Add test case for json.RawMessage schema
- Fixes issue where non-map schemas returned empty object
This fixes GitHub Copilot feedback that Parameters() was dropping
tool schema when InputSchema wasn't already map[string]interface{}
- Change NewMCPTool to accept MCPManager interface instead of concrete *mcp.Manager
- Remove unused mcpPkg import from mcp_tool.go
- Remove newMCPToolForTest helper function as NewMCPTool now accepts interface
- Update all tests to use NewMCPTool directly with MockMCPManager
- Improves testability and follows dependency inversion principle
Implement comprehensive MCP support with stdio/HTTP/SSE transports, environment variable configuration (env and envFile), custom headers, tool registration, and automatic resource cleanup. Includes full test coverage and VSCode-compatible configuration.
- Added pkg/mcp/manager.go for server lifecycle management
- Added pkg/tools/mcp_tool.go for tool wrapping
- Integrated into agent loop with cleanup
- Support for envFile loading (.env format)
- Headers injection for HTTP/SSE authentication
- Example configs for filesystem, github, brave-search, postgres
