What the code does

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Reads files and sends them to the network src/index.ts:25
import { readdirSync, lstatSync, readFileSync } from "node:fs";

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start: COSTWRIGHT_API_KEY (API key for costwright (RapidAPI key or direct Bearer). Only needed for check/certify; verify/pubkey are public.). The author declared them in the registry entry; get the values from the project itself.

costwright — agent budget analysis — questions

Answers built from our own checks of this server.

Why is there no uptime for costwright — agent budget analysis?
costwright — agent budget analysis runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package costwright-mcp was installed 43 times last week.
How do I connect costwright — agent budget analysis?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls costwright-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use costwright — agent budget analysis?
The npm package costwright-mcp was installed 43 times in the last week. Week over week that is -29%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is costwright — agent budget analysis open source?
We cannot say either way: written in JavaScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
