Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Read-only source-linked AI API prices, comparisons, cost estimates, and price changes.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.

Pick your app above. We remember it, so next time the button says “Install in …”.
Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

}Run this in your terminal
claude mcp add ai-api-pricing -- npx -y ai-api-pricing-mcpPaste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 10 days ago.

Read-only MCP server for the source-linked AICostBudget AI API Pricing Dataset. It exposes model prices, filtered model lists, monthly cost estimates, comparisons, and price-change events. Every successful result includes official provider source URL(s), a verification date, and an AICostBudget page link.
Data, history and issue tracker: aicostbudget/ai-api-pricing-data on GitHub. Spot a wrong price? Open an issue with the official source link.
The server writes no files, collects no telemetry, and uses only these public endpoints at runtime:
https://aicostbudget.github.io/ai-api-pricing-data/api/v1/prices.jsonhttps://raw.githubusercontent.com/aicostbudget/ai-api-pricing-data/main/data/price-change-events/events.jsonlhttps://aicostbudget.com/sitemap.xmlIf live pricing or price-change loading fails, the response explicitly reports that the bundled fallback was used. Model-page links are emitted only when present in the sitemap; otherwise the server links to https://aicostbudget.com/en/models.
Node.js 18 or newer is required.
npx -y ai-api-pricing-mcp
Add this entry under mcpServers in claude_desktop_config.json:
{
"mcpServers": { "ai-api-pricing": { "command": "npx", "args": ["-y", "ai-api-pricing-mcp"] } } }
Restart Claude Desktop after saving the file.
The maintainer creates the GitHub Release and attaches ai-api-pricing-mcp- .mcpb. Download the bundle from GitHub Releases, then double-click it or drag it into Claude Desktop → Settings → Extensions to install it.
claude mcp add ai-api-pricing -- npx -y ai-api-pricing-mcp
Create .cursor/mcp.json in a project, or ~/.cursor/mcp.json for global use:
{
"mcpServers": { "ai-api-pricing": { "command": "npx", "args": ["-y", "ai-api-pricing-mcp"] } } }
Create .vscode/mcp.json:
{
"servers": { "ai-api-pricing": { "type": "stdio", "command": "npx", "args": ["-y", "ai-api-pricing-mcp"] } } }
get_model_price({ model })list_models({ provider?, max_input_price?, max_output_price? })estimate_monthly_cost({ model, input_tokens_per_request, output_tokens_per_request, requests_per_month, cached_input_ratio?, use_batch? })compare_models({ models, input_tokens_per_request, output_tokens_per_request, requests_per_month })price_changes({ since?, provider? })Model matching accepts exact IDs and display names. A fuzzy query that matches multiple models returns an explicit “Did you mean” list instead of silently choosing one. Cost estimates refuse missing required prices; they never substitute a standard, cache, or batch rate.
User: Get the price of gpt-4.1.
Assistant → get_model_price: GPT-4.1; input 2, cached input 0.5, output 8 USD per 1M tokens; official source and verified date included.
User: List OpenAI models with input price at most $2 per million tokens. Assistant → list_models: Matching model IDs and source-linked rates.
User: Estimate 1,000 monthly requests with 1,000 input and 100 output tokens on gpt-4.1. Assistant → estimate_monthly_cost: $2.80 before taxes, contracts, credits, or provider rounding.
User: Compare gpt-4.1 and claude-haiku-5-5 for that workload. Assistant → compare_models: Results sorted from lowest to highest estimated total.
User: Show OpenAI price changes since 2026-01-01. Assistant → price_changes: Up to 20 newest matching events with source URLs and the price monitor link.
node and npx are on the client application's PATH.npx may need to download the package once. Corporate proxies must allow the npm registry and the three documented runtime URLs.
