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.

56 servers plus the office-suite aggregator, 46 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. The table links the demonstrations that are available; some are labeled evidence diagrams rather than client captures.

Choose the install path supported by your server.

1. Claude Desktop bundle. Choose the server in the download catalog, download its versioned .mcpb and open it.
2. Hosted, for 46 servers. Open mcp.zovo.one/mcp/connect, mint a free token and copy the ready URL for your server. That URL includes the token; a bare endpoint does not authorize tool calls. Servers without an endpoint use the bundle or source build.

The npm packages are not published. Use a bundle or the source build below rather than an npm package command.

Server	Demo	What it does	One-click bundle
mcp-amortization		Loan and lease schedules from the terms of the agreement, to the minor unit.	amortization.mcpb
mcp-asset-register		A fixed asset register that depreciates on the rates the tax authorities actually publish, with the schedule, the journal and the gain on sale.	asset-register.mcpb
mcp-backlink-checker		Backlink checks from Claude or Cursor: dofollow or nofollow, anchor text, HTTP status and robots guards.	backlink-checker.mcpb
mcp-bank-statement		Bank CSV exports categorised, summarised and reconciled with expenses.	bank-statement.mcpb
mcp-barcode

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)

46 servers have hosted endpoints. Open the connect page, get a free token and copy the complete URL for the server you need.

The ready URL has the form https://mcp.zovo.one/mcp/<server>/t/<token>. If your client supports headers, the bare endpoint also works with Authorization: Bearer <token>. The bare URL alone can initialize and list tools but refuses tool calls.

Hosted file tools accept inline data/uploads and return temporary download URLs instead of reading your local disk. Read the server-specific setup guide for supported formats. A local install is the path for files on your machine.

Office Suite, Three-Way Match and Duplicate Invoice Check are local stdio servers. Do not substitute a hosted URL for their executable. See each server page and the client setup guides.

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:

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.

Also live: 54 client-by-server setup pages (six clients: Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Cline, times every server) and 8 head-to-head compare pages against named competitor MCP servers, sourced from each competitor's own README, GitHub metadata or npm/registry record.

Validation

Before anything ships: 1,563 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/CURRENCY_AUDIT.md, docs/DOCX_AUDIT.md, docs/EXPENSE_AUDIT.md, docs/TIMEZONE_AUDIT.md, docs/USER_VALUE.md through docs/USER_VALUE_R7.md, docs/CODEX_REVIEW.md through docs/CODEX_REVIEW_V4.md, docs/CODEX_REVIEW_REMOTE.md, docs/CODEX_REVIEW_REMOTE_V2.md, docs/REMOTE_RESULT.md.

npm status

The MCP packages are not published on npm. Use the versioned download catalog, a source build, or the hosted endpoints where available. Earlier npm authentication findings are recorded in docs/NPM_AUTH_RESULT.md; an unpublished package command is not an install path.

Historical access notes

These earlier access findings have not been revalidated in this section. The released bundles, source repositories and hosted setup paths above work without these extra services:

• 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.
