Tired of unpredictable API bills from agents? Here’s a 0-dep MCP server to estimate costs in real-time.

Been running some agent workflows lately and got hit with unexpected API costs.

Tried a few tools but most were either overkill or needed extra setup just to estimate tokens.

So I made a small MCP server that just estimates cost before the call.

No deps, just stdin/stdout.

Example:

gpt-4o (8k in / 1k out) → \~$0.055

Gemini flash → way cheaper

Curious how others are handling this?
