Nanostores MCP
Debug Nanostores state in a running app by letting an agent scan stores, watch events, and pull documentation.
Overview
Nanostores MCP is a MCP server for the Build phase that helps agents debug Nanostores apps by scanning stores, monitoring events, and searching docs.
What is this MCP server?
- npm nanostores-mcp v0.1.2 with stdio transport and npx runtime hint
- Scan project stores and monitor runtime Nanostores events from the agent
- Documentation search aligned with Nanostores APIs and patterns
- Speeds up solo debugging when state bugs are hard to reproduce in chat alone
- npm package nanostores-mcp version 0.1.2
- Documented capabilities: scan stores, monitor runtime events, search docs
Community signal: 1 GitHub stars.
What problem does it solve?
Nanostores reactivity bugs are painful to explain in chat when the agent cannot see your stores or live update stream.
Who is it for?
Indie frontend devs on Nanostores (Astro/Vite-style stacks) who want MCP-assisted store debugging.
Skip if: Redux-only codebases, backend-only services with no Nanostores, or teams that forbid runtime inspection tools.
What do I get? / Deliverables
After install, your agent can inspect Nanostores structure, runtime activity, and documentation to narrow frontend state issues faster.
- stdio MCP hookup for Nanostores debugging tools
- Agent-readable store maps, event traces, and doc references for your app
Recommended MCP Servers
Journey fit
Frontend state debugging happens while you are building and stabilizing the client application. Frontend is canonical because Nanostores is a client-side atomic store library and this MCP targets store inspection and runtime behavior.
How it compares
Nanostores-specific debug MCP, not a generic React DevTools replacement or E2E test runner.
Common Questions / FAQ
Who is nanostores-mcp for?
Solo builders and frontend developers using Nanostores who want their coding agent to analyze stores and runtime behavior.
When should I use nanostores-mcp?
Use it during Build when tracking down subscription leaks, stale derived state, or unclear store wiring in a Nanostores app.
How do I add nanostores-mcp to my agent?
Add nanostores-mcp as a stdio MCP server (npx nanostores-mcp is supported) in Claude Code, Cursor, or another MCP client.
