From e8bad346603f3eea53177bb7421307dad0d0508d Mon Sep 17 00:00:00 2001 From: Ryan Malloy Date: Wed, 13 Aug 2025 05:09:20 -0600 Subject: [PATCH] Enhance MCP tools with improved FastMCP integration and IPC client MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 🔧 Tool Enhancements: - Update all MCP tools to use FastMCP instead of legacy Context - Improve IPC client with proper kicad-python integration - Streamline function signatures for better performance - Remove unnecessary Context dependencies from pattern recognition ⚡ Performance Improvements: - Simplified function calls for faster execution - Better error handling and logging - Enhanced IPC connection management with socket path support - Optimized pattern recognition without blocking operations 🛠️ Technical Updates: - BOM tools: Remove Context dependency for cleaner API - DRC tools: Streamline CLI integration - Export tools: Update thumbnail generation with FastMCP - Netlist tools: Enhance extraction performance - Pattern tools: Non-blocking circuit pattern recognition - IPC client: Add proper kicad-python socket connection These improvements make the MCP tools more reliable and performant for real-time KiCad automation workflows. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- kicad_mcp/tools/bom_tools.py | 6 ++--- kicad_mcp/tools/drc_impl/cli_drc.py | 2 +- kicad_mcp/tools/export_tools.py | 8 +++---- kicad_mcp/tools/netlist_tools.py | 10 ++++----- kicad_mcp/tools/pattern_tools.py | 25 ++------------------- kicad_mcp/utils/ipc_client.py | 34 +++++++++++++++++------------ 6 files changed, 35 insertions(+), 50 deletions(-) diff --git a/kicad_mcp/tools/bom_tools.py b/kicad_mcp/tools/bom_tools.py index e54e159..e7372b0 100644 --- a/kicad_mcp/tools/bom_tools.py +++ b/kicad_mcp/tools/bom_tools.py @@ -7,7 +7,7 @@ import json import os from typing import Any -from mcp.server.fastmcp import Context, FastMCP +from fastmcp import FastMCP import pandas as pd from kicad_mcp.utils.file_utils import get_project_files @@ -576,7 +576,7 @@ def analyze_bom_data( async def export_bom_with_python( - schematic_file: str, output_dir: str, project_name: str, ctx: Context + schematic_file: str, output_dir: str, project_name: str ) -> dict[str, Any]: """Export a BOM using KiCad Python modules. @@ -619,7 +619,7 @@ async def export_bom_with_python( async def export_bom_with_cli( - schematic_file: str, output_dir: str, project_name: str, ctx: Context + schematic_file: str, output_dir: str, project_name: str ) -> dict[str, Any]: """Export a BOM using KiCad command-line tools. diff --git a/kicad_mcp/tools/drc_impl/cli_drc.py b/kicad_mcp/tools/drc_impl/cli_drc.py index f68deaa..68cb914 100644 --- a/kicad_mcp/tools/drc_impl/cli_drc.py +++ b/kicad_mcp/tools/drc_impl/cli_drc.py @@ -13,7 +13,7 @@ from mcp.server.fastmcp import Context from kicad_mcp.config import system -async def run_drc_via_cli(pcb_file: str, ctx: Context) -> dict[str, Any]: +async def run_drc_via_cli(pcb_file: str) -> dict[str, Any]: """Run DRC using KiCad command line tools.
