README

elsm-mcp — local MCP bridge for Easy Local Storage Manager

`@elsm/mcp` is a local MCP (Model Context Protocol) server that lets any AI agent — Claude Code, Cursor, Codex, Gemini CLI, ZCode, OpenCode or anything that speaks stdio MCP — read and write the **real** browser storage (localStorage, sessionStorage, cookies, IndexedDB) of the tab you're looking at, through the [ELSM browser extension](https://easylocalstorage.dev).

Your AI agent (Claude, Codex, Cursor, ...)
        │ stdio (MCP protocol)
        ▼
  elsm-mcp  ← port 39231, pairing token in ~/.elsm-bridge/token
        │ ws://127.0.0.1:39231 (token + protocol version handshake)
        ▼
  ELSM extension (offscreen document / background page)
        │ privileged APIs (chrome.cookies, tabs, page access)
        ▼
  The active tab you are working on — its real storage

Install

npx @elsm/mcp --port 39231

The first run creates a pairing token at `~/.elsm-bridge/token` (mode 0600). Paste that token into the ELSM sidebar → **Agent access** page once per browser, then point your MCP client at `npx -y @elsm/mcp` — see the [setup guide](https://easylocalstorage.dev/docs) for per-client stanzas (Claude Code, Codex, Cursor, ZCode, OpenCode, generic `mcpServers`).

Tools

Nine tools, scoped to the active tab's origin:

Tool	Plan	What it does
`get_target`	Free	Tab id, URL, origin, title of the active tab
`list_storage_areas`	Free	Origin, storage areas present, IndexedDB database names
`read_storage`	Free	Read localStorage/sessionStorage — one key, a prefix, or everything
`read_cookies`	Free	All cookies for the tab; values unless raw-value consent is granted in the UI
`read_indexeddb`	Free	Cursor-paged, JSON-safe read of an object store
`export_state`	Free	Snapshot localStorage/sessionStorage + cookie metadata (always redacted)
`write_storage`	Pro	Write `{key, value}` entries; every write lands i
