It aims to let developers replace a server, recover from a bad build, and refresh its tool list inside an existing session. For teams iterating on local MCP integrations, it targets a disruptive restart boundary rather than adding another server capability.","published_at":"2026-10-31","updated_at":"2026-10-31","record_date":"2026-10-31","date_kind":"published_at","topics":["mcp","claude","claude-code"],"entities":["mcp-restart","Claude Code","Model Context Protocol","Node.js"],"related_patterns":["agent-protocols-become-interoperability-layer","harness-architecture-outlives-model-choice"],"novelty_label":"new_fact","what_changed":"A new Windows utility hot-swaps MCP servers in a running Claude Code session, making new tools available immediately without failed calls.","prior_refs":["memory:f19c139e-c5a5-8556-a0e7-9f44436220c8"],"source_url":"https://github.com/X-15/mcp-restart","source_urls":["https://github.com/X-15/mcp-restart"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:mcp-restart-proxy-that-hot-swaps-mcp-servers-79179d","status":"published","visuals":[],"editor":{"role":"editor","name":"Andrey Reshetnikov","profile":"https://newruntime.com/owner-profile.md","profile_json":"https://newruntime.com/owner-profile.json","same_as":["https://www.linkedin.com/in/reshetnikov1/","https://t.me/lapetuse"]},"routes":{"html":"https://newruntime.com/posts/mcp-restart-proxy-that-hot-swaps-mcp-servers-79179d/","markdown":"https://newruntime.com/posts/mcp-restart-proxy-that-hot-swaps-mcp-servers-79179d.md","json":"https://newruntime.com/posts/mcp-restart-proxy-that-hot-swaps-mcp-servers-79179d.json"},"next_reads":[{"type":"topic","path":"/topics/mcp/","url":"https://newruntime.com/topics/mcp/","title":"Mcp","reason":"Explore the mcp topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/mcp.md","json_url":"https://newruntime.com/topics/mcp.json"},{"type":"topic","path":"/topics/claude/","url":"https://newruntime.com/topics/claude/","title":"Claude","reason":"Explore the claude topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/claude.md","json_url":"https://newruntime.com/topics/claude.json"},{"type":"topic","path":"/topics/claude-code/","url":"https://newruntime.com/topics/claude-code/","title":"Claude Code","reason":"Explore the claude-code topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/claude-code.md","json_url":"https://newruntime.com/topics/claude-code.json"},{"type":"collection","path":"/posts/","url":"https://newruntime.com/posts/","title":"Field Notes","reason":"Open the latest editorial analysis.","media_type":"text/html","json_url":"https://newruntime.com/posts.json"},{"type":"collection","path":"/source-ledger.json","url":"https://newruntime.com/source-ledger.json","title":"Source Ledger","reason":"Inspect the public source evidence graph.","media_type":"application/json"}]}
