What it can do

Tool names and descriptions exactly as the server reported them on Nov 15, 2026. The maker wrote them, not us; we show them as plain text.

  • get_pricing

    Full sourced pricing record for a software product: tiers, hidden costs, contract terms, market data, sentiment, negotiation tips, TCO scenarios, price history — every claim with its sources + a confidence/verification envelope.

  • get_hidden_costs

    The documented hidden/implementation/add-on costs of a product (uplifts, onboarding fees, overages), each with a sourced quote + date. The "what they don't tell you" answer.

  • get_negotiation_tips

    Sourced negotiation tactics for a product with success-likelihood (how to get a discount).

  • get_price_history

    Dated per-quarter snapshots of a product's pricing page. Returns observations, NOT a trend figure — CostBench does not publish one, because diffing snapshots across renamed/restructured plan lineups is ~90% measurement artifact.

  • compare_software

    Side-by-side pricing comparison of 2–4 products (starting price, enterprise tier, median annual cost, free tier, ratings).

  • discover_software

    Find software products by name search or criteria (category, max price, free tier). Returns matching slugs to look up — use "query" to find the slug for a product name.

  • calculate_tco

    Total cost of ownership for a product and team size: sourced line items (licenses with price escalation, benchmark implementation), year-one + multi-year totals, effective per-seat cost. The defensible "true cost for an N-person team" answer.

  • estimate_llm_cost

    Estimate the cost of an LLM/API workload (input + output tokens) for a usage-priced provider (OpenAI, Anthropic, AWS Bedrock…) from its real rate card.

  • get_price_changes

    Recent software pricing changes CostBench detected against vendor pricing pages (increases, decreases, plan restructures) — dated, with before/after price bands and a source link. Filter by product slug, category, or lookback window. The "what changed lately" answer; each item li

Common questions

Is CostBench safe?

It passed 4 of 4 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 3 months ago, and the latest version (1.1.0) reached the registry 3 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 on the web (full MCP on Business and above; Pro read-only).

What can I use instead?

CostBench MCP Server

Verified software-pricing intelligence for any MCP client — true costs, hidden fees, negotiation data, price history, side-by-side comparisons, a dated price-change feed, and total cost of ownership for 3,390+ products. Read-only, free, no API key, no signup.

Powered by CostBench.com. Every figure the server returns carries its source and date — the data is only as trustworthy as its provenance, so CostBench publishes the provenance with each number. Responses include an attribution field and per-entity links back to the sourced page.

get_price_historyPer-quarter price snapshots + trend — has the price changed? Args: slug.
compare_softwareSide-by-side pricing for 2–4 products (starting price, median annual cost, free tier, ratings). Args: slugs (array).
discover_softwareFind products by category, maxPrice, hasFreeTier. Returns matching slugs to look up.

All tools are read-only (readOnlyHint: true). Products are addressed by slug (e.g. salesforce, microsoft-teams, openai-api); use discover_software if you don't know one.

Option 1 — Remote endpoint (recommended, no install)

The server is hosted at https://costbench.com/mcp using streamable HTTP transport (MCP spec 2025-03-26). If your client supports remote MCP servers, point it straight at the endpoint:

{

"mcpServers": { "costbench": { "type": "streamable-http", "url": "https://costbench.com/mcp" } } }

Claude Code:

claude mcp add --transport http costbench https://costbench.com/mcp

Option 2 — Local stdio server (this package)

For clients that only speak stdio, this package bridges stdio ↔ the hosted endpoint:

{

"mcpServers": { "costbench": { "command": "npx", "args": ["-y", "github:aadilr/costbench-mcp"] } } }

Or clone and run directly:

git clone https://github.com/aadilr/costbench-mcp.git

cd costbench-mcp npm install node index.js

Option 3 — Agent Skill / Claude Code plugin

This repo doubles as an Agent Skill and Claude Code plugin.

Any skills-capable agent (Claude Code, Codex CLI, Cursor, Gemini CLI, Copilot, and more):

npx skills add aadilr/costbench-mcp

Claude Code plugin (bundles the MCP server + the skill):

/plugin marketplace add aadilr/costbench-mcp

/plugin install costbench@costbench

The software-pricing skill prefers the MCP tools when connected and otherwise falls back to a bundled script (skills/software-pricing/scripts/pricing.sh) that talks to the hosted endpoint over plain HTTPS — no MCP client required.

Option 4 — Docker

docker build -t costbench-mcp .

docker run -i --rm costbench-mcp

Quick test

# List the tools

curl -X POST https://costbench.com/mcp \ -H "Content-Type: application/json" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

Get pricing for a product

curl -X POST https://costbench.com/mcp \ -H "Content-Type: application/json" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"get_pricing","arguments":{"slug":"salesforce","depth":"summary"}}}'

The get_pricing call above returns a record like:

{

"slug": "salesforce", "name": "Salesforce", "category": { "slug": "crm", "name": "CRM" }, "priceRange": { "low": 0, "median": 100, "high": 550, "currency": "USD" }, "priceUnit": "user/month", "tiers": [ { "name": "Starter Suite", "priceMonthly": 25, "priceAnnual": 300, "priceUnit": "user/month" }, { "name": "Pro Suite", "priceMonthly": 100, "priceAnnual": 1200, "priceUnit": "user/month" } ], "attribution": "Source: CostBench (https://costbench.com) — verified, sourced software pricing intelligence." }
