snippet-vault

An MCP server that gives Claude a personal code snippet library. Save snippets during any conversation and retrieve them later — across sessions, projects, and machines.

What it does

save_snippet — save any code block with a title, language, and tags

search_snippets — search by title, language, tag, or content

get_snippet — retrieve a full snippet by ID

list_snippets — see all saved snippets

delete_snippet — remove a snippet by ID

Snippets are stored locally at ~/.snippet-vault/snippets.json — your data stays on your machine.
