Local LLM cost proxy: forecasts each call and recommends the cheapest model that clears the task.
Overview
A local LLM cost advisor that estimates what a call or agent workflow would cost and recommends the cheapest model that clears the task's capability bar.
- What you can do
- Agentcents acts as a local LLM cost proxy and consulting skill: it forecasts the cost of a call or multi-step agent workflow across candidate models, compares them, and picks the cheapest model that meets the task's capability bar. It presents comparisons as Mermaid diagrams and reports honest ranges rather than false point estimates. In consult mode it answers from a bundled snapshot of model prices and Intelligence Index scores; in live mode, when the local agentcents proxy is running, it uses the user's real ledger with calibrated forecasts, spend, and accuracy.
- When to use it
- Useful when planning or budgeting LLM usage: estimating the cost of a workload such as classifying a batch of support emails, or deciding which model each step of a multi-step agent should use. It suits people who want a neutral, cost-aware model recommendation before committing to an API spend.
- Requirements
- Runs as a local process on the user's machine (desktop only, not web-executable), installed from the PyPI package agentcents over stdio. No authentication, environment variables, or headers are declared. Live mode requires the agentcents proxy to be running locally; consult mode works without installing the proxy.
Installation
In SourceWeft
- Open Agentcents in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.
README
agentcents — LLM cost consulting skill for Claude
A Claude Skill that turns Claude into a neutral LLM cost advisor: estimate what any call or agent workflow will cost across candidate models, get the cheapest model that clears the task's capability bar, and see the comparison as a Mermaid diagram — with honest ranges, never false point estimates.
Works two ways:
- Consult mode (no install): answers from a bundled, hand-verified snapshot of current model prices and Intelligence Index scores.
- Live mode: if the agentcents proxy is running locally, the skill uses your real ledger — calibrated forecasts, spend, and accuracy instead of priors.
Install
Claude.ai / Desktop: Settings → Capabilities → Skills → Add → upload this
folder (or the packaged .skill).
Claude Code: /plugin marketplace add labham-llc/agentcents-skill
then /plugin install agentcents@labham-skills
Then just ask things like:
what would it cost to classify ~500 support emails a day, about 200 tokens each?
I'm building a 5-step research agent — which model should each step use?
What's in the box

The product behind it
agentcents is a local proxy that meters,
forecasts, and budget-enforces LLM API calls — and grades its own forecasting
accuracy on a calibration page. pip install agentcents. The skill is free;
so is the agentcents free tier.
