What it does

A read-only MCP server backed by our live pricing table. Six tools, no surprises.

list_models
List LLM models with prices, filter by provider, category, or verified-only.
get_model
Full record for one model: input/output/cached prices, context window, last-verified date.
compare_models
Side-by-side price comparison for 2-6 models.
estimate_cost
Dollar cost for a given input/output token count on any model. Handles cached-input pricing.
cheapest_for
Top-N cheapest verified models in a category (fast / flagship / reasoning / embedding).
list_providers
Catalogue of every provider we track with their official pricing-page link.

Two resources are also exposed: usagewall://pricing/full (the entire table) and usagewall://pricing/<provider> (one provider, e.g. usagewall://pricing/openai).

Install in Claude

Open Claude settings

Claude Desktop → Settings → Developer → Edit Config.
Claude.ai → Settings → Connectors → Add custom connector.

Add the server

For Claude.ai custom connectors paste the URL below. For Claude Desktop config, see the JSON snippet.

Ask a question

"What's the cheapest reasoning model right now?" or "Cost of 100K input + 5K output on Claude Sonnet 4.6?"

Claude.ai custom connector

Paste this URL into the custom connector dialog:

https://usagewall.vercel.app/api/mcp

Claude Desktop config

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "usagewall": {
      "url": "https://usagewall.vercel.app/api/mcp"
    }
  }
}

Cursor / Windsurf / Zed / Cline

Same URL, drop it in the MCP server settings of any of these clients. UsageWall speaks the standard HTTP MCP transport — no SDK required, no auth handshake.

Quick check from the terminal

List tools without any client:

curl -s https://usagewall.vercel.app/api/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Estimate cost of 50K input + 2K output on GPT-4o:

curl -s https://usagewall.vercel.app/api/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"estimate_cost","arguments":{"provider":"openai","model_id":"gpt-4o","input_tokens":50000,"output_tokens":2000}}}'

What's not here

No write endpoints. Nothing in this server changes any state.
No auth, because there's nothing private to read. We're considering OAuth for a future Plus tier that exposes your own spend data.
No streaming responses for now. Tool calls return their full result in one shot — fine for pricing-sized payloads.

Source & reliability

Built on our public pricing JSON, hand-checked monthly against the providers' own pricing pages plus an OpenRouter live overlay. Models pending official pricing are marked verified: false. Bugs and price corrections welcome at hello@agenciabaku.com or on GitHub.
