CostBench tools (9)

write = sends, deletes, buys or posts
  • calculate_tcoFree

    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.

  • compare_softwareFree

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

  • discover_softwareFree

    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.

  • estimate_llm_costFree

    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_hidden_costsFree

    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_tipsFree

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

  • get_price_changesFree

    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 links to the sourced record.

  • get_price_historyFree

    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.

  • get_pricingFree

    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.

What the publisher says

From the CostBench repository's README, as published. We do not edit it. Read it on GitHub

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.

Tools

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

Shortened. The full README is on GitHub.
