License: MIT

Search your shell history (zsh / bash / fish) from Claude Code, Cline, Cursor, Zed, or any MCP client. Local-only. SQLite FTS5. Secret-redacted before storage.

demo

What you can ask

"When did I last ssh into the staging server?"
"Show recent failed commands."
"What did I run yesterday in /etc/nginx?"
"What's that long docker compose flag I used 3 weeks ago?"
"Show command chains around kubectl apply."

Install

npm install -g terminal-history-mcp
terminal-history-mcp index           # one-time backfill from existing history

(Or run from a clone: git clone … && npm install && npm run build && npm link.)

Wire to Claude Code

claude mcp add --scope user terminal-history -- terminal-history-mcp
claude mcp list

Wire to other MCP clients

Anywhere that takes a stdio MCP server config:

{
  "mcpServers": {
    "terminal-history": {
      "command": "terminal-history-mcp"
    }
  }
}

Connect via MCPize

Use this MCP server instantly with no local installation:

npx -y mcpize connect @HasanJahidul/terminal-history --client claude

Or connect at: https://mcpize.com/mcp/terminal-history

Capture cwd + exit code (recommended)

By default zsh/bash history files store only the command. To unlock recent_in_dir and failed_commands, install the shell hook:

terminal-history-mcp install-hook zsh    # or bash, or fish
exec $SHELL                              # reload

The hook appends pipe-delimited lines to ~/.terminal-history-mcp/extended.log. Reindex picks them up.

To inspect the snippet first:

terminal-history-mcp print-hook zsh

To remove:

terminal-history-mcp uninstall-hook zsh

Tools

Tool	What it does
`search_history(query, limit)`	FTS5 keyword + prefix match across all history
`recent_in_dir(cwd, limit)`	Last N commands in a working dir (needs hook)
`failed_commands(since_ts_ms, limit)`	Commands with non-zero exit (needs hook)
`command_chains(query, window_ms, limit)`	For each match, list commands within ±5 min
`reindex`	Re-parse history files + extended log
