Add critical guidance for tool selection priority to prevent duplicate integrations. Emphasizes local MCP servers (Gmail, Calendar, Reminders) over Rube/Composio fallbacks. Key changes: - Add explicit tool selection priority checklist - Document when to use local MCP vs Rube/Composio - Clarify fallback scenarios for external integrations Generated with [Claude Code](https://claude.ai/code) via [Happy](https://happy.engineering) Co-Authored-By: Claude <noreply@anthropic.com> Co-Authored-By: Happy <yesreply@happy.engineering>
Performance and reliability improvements for Reminders MCP server: - Add timing instrumentation for all API operations - Increase AppleScript timeout from 10s to 15s - Increase EventKit fetch timeout from 10s to 15s - Add [TIMING] markers for benchmark capture Timing markers enable performance profiling and help identify bottlenecks in AppleScript and EventKit async operations. Timeout increases reduce intermittent failures caused by Reminders.app latency on system load.

…marks Major UX improvement for Messages database access without Full Disk Access: Core Features: - Security-scoped bookmark support via file picker - Lazy contacts sync with tiered approach (daemon → Rust CLI → Python) - Permission checking and guided setup - TTL-based sync caching (30min default) New Files: - db_access.py: Security-scoped bookmark manager - file_picker.py: NSOpenPanel integration for bookmark creation iMessage Client Improvements: - Auto-detect running contacts daemon - Prefer Rust CLI sync (~500ms) over Python (~700ms) - Interactive permission prompts when appropriate - Graceful fallback to legacy FDA path Messages Interface Improvements: - Bookmark-first initialization (use_bookmark=True default) - Comprehensive permission checking API - Backward compatibility with explicit path mode This eliminates the need for users to grant Full Disk Access, using Apple's security-scoped bookmark API instead. Users pick the Messages database once via file picker, bookmark is stored, and future access works without FDA.

Code Review
This is an excellent pull request that delivers significant performance improvements and introduces a valuable benchmark framework. The optimizations, such as batching requests in the Gmail integration and adding daemon support, are well-executed and the performance gains are impressive. The new benchmark script is comprehensive and will be a great asset for tracking performance over time.
My review focuses on improving the maintainability and robustness of the new benchmark script. I've suggested refactoring some of the larger functions, externalizing the server configurations, and making some of the parsing logic more resilient. I also noted an opportunity to share the new TimingContext utility across different MCP servers to avoid code duplication.
Overall, these are fantastic contributions to the project's performance and stability.

The _extract_target_from_response function relies on fragile string parsing and hardcoded dictionary keys to extract target identifiers from various tool outputs. For example, it looks for lines starting with chat id: or splits strings on (.
This approach is brittle and likely to break if the output format of any of the benchmarked tools changes. This poses a correctness risk to workloads that depend on target selection.
To make this more robust, I recommend one of the following:
- Preferred: Modify the tools to return a structured JSON response with a consistent, well-defined key for the target identifier (e.g.,
{"target_id": "..."}). - Alternative: If modifying the tools isn't feasible, add extensive comments to this function documenting the exact expected output format for each
kindto make future maintenance easier.

The TimingContext class is a useful utility for performance profiling. Since the PR description mentions adding timing instrumentation to other integrations like Gmail and Calendar, this context manager is likely to be needed in other server files as well.
To promote code reuse and avoid duplication, consider moving TimingContext and its _timing helper function to a shared utility module within the project, for example, in a mcp.utils or mcp.profiling module. This will make it easier to apply consistent timing instrumentation across all MCP servers.

There was a problem hiding this comment.
The exception handling for JSON decoding is too broad. The except Exception: continue block will silently ignore any json.JSONDecodeError or other issues during parsing. This can make debugging failed benchmark runs very difficult, as malformed output from a server will be silently skipped.
It would be better to catch the specific json.JSONDecodeError, log a warning with the problematic line, and then continue. This would provide valuable debugging information without halting the entire benchmark suite.
For example:
import logging
...
try:
obj = json.loads(line.decode("utf-8", errors="ignore"))
except json.JSONDecodeError:
logging.warning(f"Failed to decode JSON from line: {line!r}")
continue

The _run_session function is very long (over 250 lines) and has high cyclomatic complexity. It handles process lifecycle, RPC communication, workload orchestration, target selection, result validation, and result aggregation.
To improve maintainability and readability, this function should be refactored into several smaller, more focused helper functions. For example:
- A function to handle the session initialization (
initializeandtools/list). - A function to run a single workload, including target selection, warmup, and measured calls.
- A function to process and summarize the results.
Breaking down this monolithic function will make the code easier to understand, test, and modify in the future.

The main function has a large, hardcoded list of McpServerSpec configurations. This makes the script hard to read and maintain. Adding or modifying server configurations requires changing the script's code.
Consider moving these server definitions into a separate configuration file (e.g., servers.json or config.yaml). The script could then load this file at runtime. This would decouple the benchmark logic from the configuration, making it much easier to manage the list of servers to be tested.
…commands Implements complete Phase 3 of Rust CLI migration with 9 new commands: Analytics commands: - analytics: Conversation statistics with 6 SQL queries (message counts, busiest hour/day, top contacts, attachments, reactions) - followup: Detect unanswered questions and stale conversations - reactions: Query tapback messages (already implemented in reading.rs) Discovery commands: - handles: List all unique phone/email handles - unknown: Find messages from non-contacts - discover: Frequent texters not in contacts - scheduled: Scheduled messages stub (not supported by Messages.db) Groups commands: - groups: List all group chats with participants - group-messages: Get messages from specific groups (by group_id or participant) All commands support both JSON and human-readable output formats. Development time: ~15 minutes across 3 sprints (3A, 3B, 3C) Build time: <2s Test coverage: Manual testing verified all commands working Phase 3 completes feature parity with Python gateway for analytics, discovery, and groups functionality.

When --use-daemon is set, main() skips creating a GoogleCalendarClient, but cmd_events still calls client.list_events(...) unconditionally. That means calendar_cli.py events ... --use-daemon raises an AttributeError (and the same pattern exists for get/create/delete), so these commands are unusable in daemon mode. Either wire these commands through the daemon client or reject --use-daemon for them to avoid runtime crashes.

There was a problem hiding this comment.
cmd_stop always sends SIGTERM to the PID from the pidfile without verifying the daemon is still running. Because the pidfile is only removed by cmd_stop (the SIGTERM/SIGINT handlers just close the server), a crash or manual interrupt can leave a stale pidfile; if that PID gets reused, stop can terminate an unrelated process. Consider cleaning the pidfile on shutdown or validating the socket before signaling.
