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.
Three tools against the 100-tool ceiling; the assumptions are stated in the source, which is the honesty you want from a number you defend to clients.
| 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_config.json, and the key inside it is mcpServers.

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.
Windsurf 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"]
}
}
}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"]
}
}
}Save and reopen the MCP Servers list; Cascade picks it up without restarting the editor.
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.
Read this first: mcp_config.json applies to the legacy Cascade agent only. The Devin Local agent, the default for new tabs, takes its servers from the Devin CLI config files, so a correct entry here can still be invisible in a fresh tab. The other hard number is a cap: Cascade reaches at most 100 tools at once, and every enabled server spends from it.
Free: Everything: three tools, no metering, no key. Pro is $19 once, verified offline.
~/.codeium/windsurf/mcp_config.json, under mcpServers. Reach it from the MCPs icon at the top right of the Cascade panel, or Devin Settings, Cascade, MCP Servers.
That file applies to the legacy Cascade agent only. The Devin Local agent, the default for new tabs, reads its servers from the Devin CLI config files instead. Check which agent the tab runs.
Cascade reaches at most 100 tools at any one time, and every enabled server spends from that single budget. MCP Hourly Rate Calculator contributes 3 tools, so keep the enabled list short rather than counting servers.
