Local always-on server for SnapStack: browser capture intake + MCP over 127.0.0.1.
Local always-on server for SnapStack: browser capture intake + MCP over 127.0.0.1. That is what the snapstack mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
The SnapStack server is a single always-on Node process: it receives browser captures from the extension, stacks them on disk, and serves them to any MCP-capable LLM client over Streamable HTTP. It listens only on 127.0.0.1 — nothing ever leaves your machine.
Installation goes through your MCP client rather than a global install: point it at and on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
The server publishes 3 tools. What each one is for:
get_screenshots — Lists pending captures as a JSON manifest (stable number, absolute path, dimensions, metadata) — no image bytes, no deletion. Pass numbers (e.gclear_screenshots — Deletes captures. Pass numbers to delete specific ones; omit to clear the whole stack. Numbering restarts at 01 once emptycount_screenshots — Number of pending captures, without retrieving themPlenty of browser automation servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Snapstack's toolset — get_screenshots, clear_screenshots, count_screenshots — is a fair guide to whether it matches your workflow. It is maintained by bgaze; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
| Tool | What it does |
|---|---|
| get_screenshots | Lists pending captures as a JSON manifest (stable number, absolute path, dimensions, metadata) — **no image bytes, no deletion**. Pass numbers (e.g. [1,3]) to list only those. |
| clear_screenshots | Deletes captures. Pass numbers to delete specific ones; omit to clear the whole stack. Numbering restarts at 01 once empty. |
| count_screenshots | Number of pending captures, without retrieving them. |
