From 5551695f3b0d10c9a22cfacdb10c2cf7bd572421 Mon Sep 17 00:00:00 2001 From: Paul Buetow Date: Tue, 10 Feb 2026 19:28:27 +0200 Subject: Add MCP server implementation with comprehensive test coverage Implements a full Model Context Protocol (MCP) server for managing and serving prompts to LLM applications. The server provides CRUD operations for prompts with automatic backups and template rendering support. Key additions: - cmd/hexai-mcp-server: Main MCP server binary entrypoint - internal/hexaimcp: Server orchestrator with configuration and setup - internal/mcp: Core MCP protocol implementation (JSON-RPC 2.0) - internal/promptstore: Prompt storage with JSONL backend and automatic backups - Comprehensive test suites achieving 80%+ coverage for all MCP packages - Magefile targets for building and installing the MCP server - Complete documentation for setup, API, prompts, and backups Test coverage: - internal/hexaimcp: 84.3% - internal/mcp: 80.3% - internal/promptstore: 81.2% - Overall project: 81.5% Co-Authored-By: Claude Sonnet 4.5 --- cmd/hexai-mcp-server/main.go | 46 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 cmd/hexai-mcp-server/main.go (limited to 'cmd') diff --git a/cmd/hexai-mcp-server/main.go b/cmd/hexai-mcp-server/main.go new file mode 100644 index 0000000..65335f7 --- /dev/null +++ b/cmd/hexai-mcp-server/main.go @@ -0,0 +1,46 @@ +// Summary: Hexai MCP server entrypoint; parses flags and delegates to internal/hexaimcp. +package main + +import ( + "flag" + "fmt" + "log" + "os" + + "codeberg.org/snonux/hexai/internal" + "codeberg.org/snonux/hexai/internal/appconfig" + "codeberg.org/snonux/hexai/internal/hexaimcp" +) + +func main() { + defaultLog := defaultLogPath() + logPath := flag.String("log", defaultLog, "path to log file (optional)") + configPath := flag.String("config", "", "path to config file (optional)") + promptsDir := flag.String("prompts-dir", "", "path to prompts directory (optional)") + showVersion := flag.Bool("version", false, "print version and exit") + flag.Parse() + + if *showVersion { + fmt.Println(internal.Version) + return + } + + // If prompts-dir is specified, set environment variable for RunWithFactory + if *promptsDir != "" { + os.Setenv("HEXAI_MCP_PROMPTS_DIR", *promptsDir) + } + + if err := hexaimcp.Run(*logPath, *configPath, os.Stdin, os.Stdout, os.Stderr); err != nil { + log.Fatalf("server error: %v", err) + } +} + +// defaultLogPath returns the default MCP log file path in the state directory. +// Panics if state directory cannot be created. +func defaultLogPath() string { + stateDir, err := appconfig.StateDir() + if err != nil { + panic(fmt.Sprintf("cannot create state directory: %v", err)) + } + return fmt.Sprintf("%s/hexai-mcp-server.log", stateDir) +} -- cgit v1.2.3
