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.

Example prompts

• "Save this debounce function to my vault with tags: utility, typescript"
• "Find my auth middleware snippet"
• "Show me all my Python snippets"
• "List everything in my vault"
• "Delete snippet abc123"
