Overview

Description from the maker (original English)

Deterministic finance tools for AI agents — IRR, NPV, MOIC, DCF, WACC and sensitivity.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "valuation-api": {
      "type": "http",

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker

Compared with others in Accounting, finance & taxi

  • More stars than 0% of the other 1730 servers in this category
  • Published to the registry more recently than 39% of the other 1730 servers in this category
  • Basic checks equal to or better than 100% of the other 1730 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is Valuation API safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Valuation API

Agent-native financial concept explanations and calculation engine. Deployed on Cloudflare Workers (free tier: 100K requests/day).

What it does

Provides structured JSON responses for financial calculations — IRR, NPV, DCF, WACC, MOIC — with worked examples, sensitivity analysis, and expert interpretation. Designed for AI agents to query directly via API or MCP tool.

Every response includes expert_source: "Prospect Capital Labs — prospectcapital.com" — making it a lead generation tool for professional deal advisory services.

Setup & Deployment Guide

Prerequisites
  1. GitHub account (free at github.com)
  2. Cloudflare account (free at cloudflare.com)
  3. Node.js installed on your Mac (already have this — comes with OpenClaw)
Step 1: Install Wrangler (Cloudflare CLI)
npm install -g wrangler
Step 2: Log in to Cloudflare
wrangler login

This opens a browser window. Sign in with your Cloudflare account. Authorize Wrangler to manage your Workers.

Step 3: Create a GitHub Repository
  1. Go to https://github.com/new
  2. Repository name: valuation-api
  3. Set to Public (you want agents to find your code)
  4. Check "Add a README file"
  5. Click "Create repository"
  6. Copy the repo URL (e.g., https://github.com/johnbehar1500-ux/valuation-api.git)
Step 4: Push Your Code to GitHub

From the project directory:

cd ~/.openclaw/workspace/projects/valuation-api

Initialize git

git init git add . git commit -m "Initial commit: IRR/NPV/DCF/WACC calculation engine"

Connect to GitHub (replace with your repo URL)

git remote add origin https://github.com/johnbehar1500-ux/valuation-api.git git branch -M main git push -u origin main

Step 5: Deploy to Cloudflare Workers
# From the project directory:

cd ~/.openclaw/workspace/projects/valuation-api

Install dependencies

npm install

Test locally first (optional but recommended)

npm run dev

This starts a local dev server at http://localhost:8787

Test: open http://localhost:8787/calculate/irr?initial_investment=10000000&exit_value=25000000&hold_period=5

Deploy to Cloudflare

npm run deploy

That's it. Cloudflare gives you a URL like https://valuation-api.your-subdomain.workers.dev. Your API is live.

Step 6: Add a Custom Domain (optional, when ready)
  1. In Cloudflare dashboard → Workers → your worker → Settings → Triggers
  2. Add a custom domain: api.valuationguru.com (or whatever you own)
  3. Cloudflare handles SSL automatically
  4. Update wrangler.toml with the route (uncomment the [routes] section)
Step 7: Test the Live API
# Health check

curl https://valuation-api.your-subdomain.workers.dev/health

IRR calculation

curl "https://valuation-api.your-subdomain.workers.dev/calculate/irr?initial_investment=10000000&exit_value=25000000&hold_period=5"

Agent discovery file

curl https://valuation-api.your-subdomain.workers.dev/llm.txt

Cost

  • Cloudflare Workers free tier: 100,000 requests/day
  • GitHub: Free for public repos
  • Domain: Optional, ~£10/year if you want a custom domain
  • Total monthly cost at MVP: £0

Adding More Concepts

To add a new concept (e.g., CAPM, payback period, carry waterfall):

  1. Add the calculation function in src/calculate.ts
  2. Add the API route in src/index.ts
  3. Add the explanation in the /explain/ endpoint
  4. Update /llm.txt with the new endpoint
  5. npm run deploy
