🏴‍☠️ agentvault-tools

The essential MCP toolkit — 9 tools, zero API keys, one install.

Give your AI agent web search, page fetching, persistent memory, timezone conversion, and a calculator — all in a single MCP server. No API keys, no accounts, no cloud required.

Why this?

Starting with MCP? You need this one package:

npx agentvault-tools

That's it. Your agent now has 9 tools.

Tools

🔍 Web

Tool	Description
web_search	Search via DuckDuckGo (no API key!)
web_fetch	Fetch any URL → clean text

🧮 Utility

Tool	Description
datetime	Current time in any timezone
calc	Evaluate math expressions

🧠 Memory (persistent, local)

Tool	Description
save_memory	Save text with tags & importance
search_memory	Full-text search across all memories
list_memories	Browse recent or filter by tag
delete_memory	Remove a memory
memory_stats	Usage statistics

Memory persists across sessions in a local SQLite database (~/.agentvault/memory.db). Data never leaves your machine.

Quick Start

Claude Desktop

{
  "mcpServers": {
    "tools": {
      "command": "npx",
      "args": ["-y", "agentvault-tools"]
    }
  }
}

Cursor / Windsurf

{
  "tools": {
    "command": "npx",
    "args": ["-y", "agentvault-tools"]
  }
}

What happens next

Your agent can now:

• Search: "Find the latest Node.js release notes" → web_search
• Read: "What does that page say?" → web_fetch
• Remember: "Remember that the API key is xyz" → save_memory
• Recall: "What was that API key?" → search_memory
• Calculate: "What's 15% of 2,450?" → calc
• Time: "What time is it in Tokyo?" → datetime

Privacy

• All data stays local. Memory is stored at ~/.agentvault/memory.db
• No telemetry by default. Set AGENTVAULT_TELEMETRY=true to opt in
• Search queries and URLs are never sent even with telemetry on
