Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.10705 | $0.10705 |
| Opus 5 | $0.05352 | $0.05352 |
| Sonnet 5 | $0.02141 | $0.02141 |
| Haiku 4.5 | $0.01070 | $0.01070 |
Grade A, and why
kalshi-mcp-server AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 780 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent guide
This file is for any agent working on this repo — Claude Code, Cursor,
Codex, Aider, etc. Conventions live here; tool-specific files (like
CLAUDE.md) simply point back to this document.
If you're a human reading this for the first time, it's also a perfectly good architectural overview — start with the "Repo layout" and "How authentication works" sections.
What this project is
A Model Context Protocol server for Kalshi, implemented in Python on top of FastMCP. It speaks the Kalshi REST API (and eventually the WebSocket API) and exposes tools + resources that an LLM agent can use to query markets, inspect a portfolio, and place trades.
The repo is designed to be forked. Conventions, safety controls, and documentation should be useful to anyone who clones the project. Write for a stranger, not for the current owner.

How authentication works
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

kalshi-mcp-server AGENTS.md is an instructions file published in the GitHub repository cejor6/kalshi-mcp-server (3 stars, last pushed today), licensed MIT. It adds 10,705 tokens to every session, about $0.0535 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
