Price your hours from income, expenses, and tax, with what-if scenarios. calculate_rate turns desired annual income, billable hours per week, weeks per year, business expenses, and tax rate into a defensible hourly rate; break_even shows the rate that exactly covers costs; what_if re-prices after any single input moves. All arithmetic is exact and the formula is in the source.
Pure function, no state: auto-approve without hesitation, the worst outcome is a planning number you would sanity-check anyway.
| You say | Tool |
|---|---|
| I want 75,000 a year, 25 billable hours a week, 46 weeks, 12,000 expenses, 28 percent tax. | calculate_rate |
| What if I only manage 40 weeks? | what_if |
| What rate just covers my costs? | break_even |
The contract suite walks a real stdio case through the formula: 60,000 income plus 10,000 expenses over 1,150 billable hours at a 30 percent tax rate returns an 86.96 break-even-style rate, hostile inputs are refused with a reason, and nothing hangs.
The file is mcp.json, and the key inside it is mcpServers.
| Scope | Path |
|---|---|
| Cline CLI | ~/.cline/mcp.json |
| The editor extension | opened from the Cline panel, not by path; the documentation deliberately calls it the MCP settings JSON used by the extension |
If you also run Claude Desktop, the shortest path there is one click: hourly-rate.mcpb
from the latest release opens as an extension, with no JSON and no terminal.
Cline reads its own config, so here it is:
The config block:
{
"mcpServers": {
"hourly-rate": {
"command": "node",
"args": ["/absolute/path/to/mcp-servers/servers/hourly-rate/dist/index.js"],
"disabled": false,
"autoApprove": []
}
}
}The node command above wants a built file. From a clone, once:
git clone https://github.com/theluckystrike/mcp-servers.git
cd mcp-servers && npm install
npm run build -w packages/mcp-license -w servers/hourly-rateThat writes servers/hourly-rate/dist/index.js, and its absolute path is the one argument
the config needs.
The npm packages are not published yet, so the form below returns a 404 today. It is here because it is what the entry becomes the day the publish lands, with nothing else changed:
{
"mcpServers": {
"hourly-rate": {
"command": "npx",
"args": ["-y", "@theluckystrike/mcp-hourly-rate"]
}
}
}No full-app restart. The MCP settings actions include restarting an unresponsive server if its tools do not appear.
Nothing is published to npm yet, so the working install paths are the ones above: the .mcpb bundle from the latest release, a clone and build, or the hosted URL.
There is no hosted endpoint for this one yet. MCP Hourly Rate Calculator runs locally over stdio with the config above, which is also the only form in which it reads and writes files on your own disk. Thirty of the servers in this collection are served at https://mcp.zovo.one/mcp/<name> over MCP streamable HTTP; https://mcp.zovo.one/mcp/connect lists them and prints a ready URL for each.
Cline is the one client here with an unsafe transport default. `type` selects it, and omitting `type` falls back to the legacy sse transport, so a streamable HTTP endpoint needs it written in or you will debug a server that is fine. Local entries carry "disabled" and an "autoApprove" array.
Free: Everything: three tools, no metering, no key. Pro is $19 once, verified offline.
The CLI reads ~/.cline/mcp.json. For the extension, do not hunt for a path: MCP Servers icon, Configure tab, Configure MCP Servers. cline mcp opens a wizard, and cline config mcp --json is the non-interactive form.
Set the transport explicitly. Omitting type falls back to the legacy sse transport, so streamable HTTP needs "type": "streamableHttp" written in. It is the one default here that sends you debugging a server that works.
Approve the read-only ones and leave the writing ones behind a click: each entry carries an autoApprove array and a disabled flag.
