MCP servers by theluckystrike

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.

46 servers plus the office-suite aggregator, 45 of them also reachable as a hosted endpoint with no install.

No install? Use any server instantly as a hosted endpoint: https://mcp.zovo.one/mcp/<server> — or browse the catalog at mcp.zovo.one.

That is the invoice server answering a real prompt: a client, some hours, a VAT rate, and a numbered PDF at the end.Every server in the table below has a demo like it.

Two ways to run any of these, both working today.

1. One click. Download the server's .mcpb bundle from the latest release and open it in Claude Desktop. No terminal, no config file.
2. No install at all. Point a client at https://mcp.zovo.one/mcp/<server>. GET https://mcp.zovo.one/mcp/connect mints a free token and prints a ready URL for each server.

A third way is coming and does not work yet: the npm packages are unpublished, so npx -y @theluckystrike/mcp-<name>returns 404 today. The commands below are written for the day it is published; use one of the two paths above until then.

Hosted endpoints (no install)

Thirty of the servers are also live behind streamable HTTP, for clients that connect to a URL instead ofspawning a local process:

• Base URL: https://mcp.zovo.one/mcp -- GET returns an index of the endpoints; each server ishttps://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 sameway 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 virtualfilesystem first, then sheet_query, sheet_stats, sheet_add_column and sheet_convert work on it asusual. 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 andhistorical rate files are hydrated read-only from shared:ecb:daily / shared:ecb:history and neverwritten 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 onehour; 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, whichhas 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 directoryname, for example time-tracker-timesheet-billable-hours instead of time-tracker, oroffice-suite-time-invoice-expense-excel-price instead of office-suite: every extra token is a word theserver's own tool descriptions already use, and registry search matches on whole words, so a name built onlyfrom time-tracker was invisible to a search for "timesheet" or "billable hours". The full list, read fromeach server's server.mcpb.json:

The old short names are deprecated on the registry; npm package names, directory names and checkout URLs areunchanged.

Why these servers

The median MCP server on the public registry gets installed and never called again. Looking at what actually getsused, two things separate the servers people keep: a config snippet that works on the first try, and a visibledemo of the tool actually answering a real prompt before anyone installs it. Both of those are cheap to provide andmost servers skip them -- READMEs bury the config three scroll-lengths down, or show no output at all. These serverswere picked because they replace a task people already do in a spreadsheet, a SaaS dashboard or a browsertab (tracking time, watching a price, editing a sheet, cutting an invoice, logging a receipt, converting acurrency, drafting a Word document, finding a meeting slot across time zones) with one that runsentirely on-device: no account, no telemetry, no server-side data at rest (the hosted endpoints are the oneexception, and they say plainly what they keep and for how long). office-suite exists because the most-usedserver in this category, measured across the registry, is an aggregator: one install beats thirty-one.

Validation

Before anything ships: 1,563 unit tests across the servers and the shared license package (protocol smoketests over real stdio, plus adversarial cases: bad input, oversized strings, path traversal, concurrentwriters, zero-byte files), a 951-check live validation database run against the built servers and the hostedworker (data/validation.json, run 50), seven rounds of user-value testing through a real MCP client (oneprompt per conversation, not a unit test; round 7 is cross-server, chaining calls across the wholeoffice-suite bundle), and four rounds of independent Codex model review of the core build plus two more of theremote hosted worker. Details: docs/AUDIT.md, docs/CURRENCY_AUDIT.md,docs/DOCX_AUDIT.md, docs/EXPENSE_AUDIT.md,docs/TIMEZONE_AUDIT.md, docs/USER_VALUE.md throughdocs/USER_VALUE_R7.md, docs/CODEX_REVIEW.md throughdocs/CODEX_REVIEW_V4.md, docs/CODEX_REVIEW_REMOTE.md,docs/CODEX_REVIEW_REMOTE_V2.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 runnpm login --auth-type=web (seedocs/NPM_AUTH_RESULT.md). The working install paths today are the .mcpb one-clickbundle from the latest release, a clone andbuild from source, or the hosted endpoints above -- no local install at all. The npx lines in this README andin 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 onebrowser 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.comsubmissions -- was completed without a human at the keyboard.
