Software your AI can run. Let Claude, ChatGPT, or Cursor send invoices and take payment — card or ACH. You approve every send. No monthly fee. Tell the AI you already use who to bill and how much: it drafts the invoice, shows you a preview, and sends it the moment you confirm. Your client gets a payment link; you get paid by card or ACH, and you're told when the money lands. Quotes, clients, and recurring invoices included. Create a free key in your Holdings workspace → Settings → API keys. No monthly fee.

Does not connect to bank accounts.

Order food on DoorDash: searches stores, compares real fee-included totals from live quotes, builds carts, plus groceries, promos, pickup, reorders and spend history.

Renders HTML in a headless browser and detects layout defects numerically (text overlap, element overflow, placeholder leftovers) without requiring baseline images. Read-only, no API key required.

Drive full-screen terminal programs (vim, htop, lazygit) by reading the screen, not the byte stream: a live cell grid exposes which row is reverse-video selected, cursor position and alt-screen state, so waits are screen-state predicates instead of sleeps. The emulation is differentially tested against real tmux and GNU screen (cell-by-cell grid diffs plus a generative VT fuzz), which caught 12 emulation bugs including missing alternate-screen support. pip install smartcli-toolkit then smartcli-mcp, or uvx --from smartcli-toolkit smartcli-mcp.

Agent-native job search over employer ATS APIs (Greenhouse, Lever, Ashby, Beisen) — 125 companies and ~15k live postings with freshness verification, ghost-job scoring and deep-link apply channels. Résumés never transit the server; matching runs client-side.

bash for AI agents on Windows via deterministic bash→PowerShell translation — no WSL, VM, or bash toolchain. MCP `bash` tool with GNU-style output, bash-style errors, coreutils exit codes, session-persisted cwd/env across calls, and per-file UTF-8/GBK sniffing (GBK files grep correctly, unlike Git Bash). Unsupported bash constructs fail loudly with the construct named; native commands (git/node/npm) pass through with argv quoting. `npm install -g fauxnix-cli`; verified with Claude Code, Codex, OpenCode, Kimi Code and Qwen Code.

Read-only SQL across PostgreSQL, MySQL, S3-compatible buckets and folders of Parquet/CSV/JSON — and one query can join across all of them, federated in-process by DuckDB. No tool writes: they are absent rather than disabled, and every tool declares `readOnlyHint`. Runs from connection strings alone as `docker run -i --rm slotix/stream-mcp postgres://…` or as a one-click Claude extension.

Read-only MCP over the SQL database behind an ERP (Logo Tiger, Netsis, Mikro). The agent sees canonical entities like `orders`, never raw ERP tables, through a four-layer read-only guard that checks the statement, fails closed, and blocks side-effecting functions (`pg_read_file`, `xp_cmdshell`, …) — measured by a public 28-attack benchmark and an in-browser "break it" playground running the real guard via Pyodide.
