# MCP servers by theluckystrike
<!-- gen:badge -->
<!-- /gen:badge -->
Practical Model Context Protocol servers for people who work inside Claude, Cursor and other MCP clients.
Every server runs locally over stdio, keeps all data on your machine, and has a genuinely useful free tier.
Pro unlocks the limits for a one-time payment: $19 per server or $39 for the bundle, lifetime.
<!-- gen:counts -->
31 servers plus the office-suite aggregator, 30 of them also reachable as a hosted endpoint with no install.
<!-- /gen:counts -->
<!-- gen:install -->
Install any server by downloading its `.mcpb` bundle from the
[latest release](https://github.com/theluckystrike/mcp-servers/releases/latest) and opening it in Claude Desktop. That is one double-click, no terminal.
The npm packages are **not published yet**, so `npx -y @theluckystrike/mcp-<name>` returns 404. Do not use it, and
do not recommend it. The two paths that work today are the `.mcpb` bundle above and the hosted endpoints at
`https://mcp.zovo.one/mcp/<server>`, which need no install at all.

<!-- /gen:table -->
Or clone and build: `git clone https://github.com/theluckystrike/mcp-servers.git && cd mcp-servers`,
`npm install`, `npm run build`. Each server's README has the full 60-second install with every client config.
Buy Pro: https://mcp.zovo.one (keys verify offline with Ed25519; no phone-home).
## Hosted endpoints (no install)
Thirty of the servers are also live behind streamable HTTP, for clients that connect to a URL instead of
spawning a local process:
- Base URL: `https://mcp.zovo.one/mcp` -- `GET` returns an index of the endpoints; each server is
`https://mcp.zovo.one/mcp/<server>` (time-tracker, price-tracker, spreadsheet, invoice, expense-tracker,
currency, docx, timezone).
- Auth: `Authorization: Bearer <token>`. `GET https://mcp.zovo.one/mcp/token` mints a free anonymous token
(`anon_<32 hex>`, 30-day KV TTL, refreshed on every request); a Pro license key (`MCPL1....`) works the same
way and lifts the free-tier limits.
- `spreadsheet` runs in inline-data mode remotely, since a hosted worker has no disk to read a path from:
`sheet_load {name, csv}` or `sheet_load {name, xlsx_base64}` loads the data into the request's virtual
filesystem first, then `sheet_query`, `sheet_stats`, `sheet_add_column` and `sheet_convert` work on it as
usual. The stdio install is still the answer for files that live on your own disk.
- `currency` shares one ECB rate cache across every tenant instead of paying for it per token: the daily and
historical rate files are hydrated read-only from `shared:ecb:daily` / `shared:ecb:history` and never
written into any tenant's document, so the endpoint keeps no per-token state at all.
- `docx` accepts an upload the same way spreadsheet accepts inline data (`doc_upload` replaces a file path),
and every generated `.docx` comes back as the real binary Word file behind a download link, not HTML.
- Anything else a tool would normally write to a file (an invoice PDF, a CSV export, a converted spreadsheet,
an .ics invite) comes back as a download link, `https://mcp.zovo.one/mcp/download/<token>`, valid for one
hour; invoices render as an HTML document rather than a PDF on this path.
- office-suite is not hosted: it is a stdio proxy that spawns the other eight as local child processes, which
has no meaning on a remote worker. Install it locally to get all eight in one config line instead.
## Registry names
The MCP registry listing for these servers uses word-rich names instead of the plain directory
name, for example `time-tracker-timesheet-billable-hours` instead of `time-tracker`, or
`office-suite-time-invoice-expense-excel-price` instead of `office-suite`: every extra token is a word the
server's own tool descriptions already use, and registry search matches on whole words, so a name built only
from `time-tracker` was invisible to a search for "timesheet" or "billable hours". The full list, read from
each server's `server.mcpb.json`:
| Server | Registry name |
|---|---|
| time-tracker | `io.github.theluckystrike/time-tracker-timesheet-billable-hours` |
| price-tracker | `io.github.theluckystrike/price-tracker-drop-alert-watch` |
| spreadsheet | `io.github.theluckystrike/excel-spreadsheet-xlsx-csv` |
| invoice | `io.github.theluckystrike/invoice-pdf-billing-generator` |
| expense-tracker | `io.github.theluckystrike/expense-tracker-receipts-mileage` |
| currency | `io.github.theluckystrike/currency-converter-ecb-rates-daily-keyless` |
| docx | `io.github.theluckystrike/docx-document-generator-proposal-contract-markdown` |
| timezone | `io.github.theluckystrike/timezone-world-clock-meeting-slots-overlap-ics` |
| office-suite | `io.github.theluckystrike/office-suite-time-invoice-expense-excel-price` |
The old short names are deprecated on the registry; npm package names, directory names and checkout URLs are
unchanged.
## Why these servers
The median MCP server on the public registry gets installed and never called again. Looking at what actually gets
used, two things separate the servers people keep: a config snippet that works on the first try, and a visible
demo of the tool actually answering a real prompt before anyone installs it. Both of those are cheap to provide and
most servers skip them -- READMEs bury the config three scroll-lengths down, or show no output at all. These servers
were picked because they replace a task people already do in a spreadsheet, a SaaS dashboard or a browser
tab (tracking time, watching a price, editing a sheet, cutting an invoice, logging a receipt, converting a
currency, drafting a Word document, finding a meeting slot across time zones) with one that runs
entirely on-device: no account, no telemetry, no server-side data at rest (the hosted endpoints are the one
exception, and they say plainly what they keep and for how long). office-suite exists because the most-used
server in this category, measured across the registry, is an aggregator: one install beats thirty-one.

against named competitor MCP servers, sourced from each competitor's own README, GitHub metadata or npm/registry
record.
## Validation
Before anything ships: 1,507 unit tests across the servers and the shared license package (protocol smoke
tests over real stdio, plus adversarial cases: bad input, oversized strings, path traversal, concurrent
writers, zero-byte files), a 951-check live validation database run against the built servers and the hosted
worker (`data/validation.json`, run 50), seven rounds of user-value testing through a real MCP client (one
prompt per conversation, not a unit test; round 7 is cross-server, chaining calls across the whole
office-suite bundle), and four rounds of independent Codex model review of the core build plus two more of the
remote hosted worker. Details: [docs/AUDIT.md](docs/AUDIT.md), [docs/CURRENCY_AUDIT.md](docs/CURRENCY_AUDIT.md),
[docs/DOCX_AUDIT.md](docs/DOCX_AUDIT.md), [docs/EXPENSE_AUDIT.md](docs/EXPENSE_AUDIT.md),
[docs/TIMEZONE_AUDIT.md](docs/TIMEZONE_AUDIT.md), [docs/USER_VALUE.md](docs/USER_VALUE.md) through
[docs/USER_VALUE_R7.md](docs/USER_VALUE_R7.md), [docs/CODEX_REVIEW.md](docs/CODEX_REVIEW.md) through
[docs/CODEX_REVIEW_V4.md](docs/CODEX_REVIEW_V4.md), [docs/CODEX_REVIEW_REMOTE.md](docs/CODEX_REVIEW_REMOTE.md),
[docs/CODEX_REVIEW_REMOTE_V2.md](docs/CODEX_REVIEW_REMOTE_V2.md), [docs/REMOTE_RESULT.md](docs/REMOTE_RESULT.md).
## npm status
None of the packages are on npm yet. The account has never published, and the remaining step needs a person to run
`npm login --auth-type=web` (see
[docs/NPM_AUTH_RESULT.md](docs/NPM_AUTH_RESULT.md)). The working install paths today are the `.mcpb` one-click
bundle from the [latest release](https://github.com/theluckystrike/mcp-servers/releases/latest), a clone and
build from source, or the hosted endpoints above -- no local install at all. The `npx` lines in this README and
in each server's own README start working the moment npm publish succeeds; nothing else about them changes.
## Human-gated surfaces
A few distribution surfaces cannot be finished by an agent and are waiting on one human step:
- **npm** -- publish token is dead; needs `npm login --auth-type=web` once, in a browser, from this account.
- **Smithery** -- CLI and REST are otherwise fully scriptable with a bearer key, but getting that key needs one
browser login: `npx -y @smithery/cli auth login`, then open the printed `smithery.ai/auth/cli?s=<session>`
URL. `smithery.yaml` is already validated against the CLI schema.
Everything else in this repository -- registry, GitHub, `.mcpb` release, billing, hosted endpoints, guides,
setup pages, compare pages, Docker MCP catalog PR, Cline marketplace issues, mcpservers.org and mcpmarket.com
submissions -- was completed without a human at the keyboard.
Repository layout: `servers/*` one package per server, `packages/mcp-license` shared licensing, `billing/` Cloudflare Worker
that sells keys and serves the marketing site (guides, setup pages, compare pages) through Stripe Checkout,
`remote/` Cloudflare Worker serving the hosted endpoints, `dashboard/` status page, `docs/` runbooks.
