AGENTS.md

meridian-edge-mcp AGENTS.md is an instructions file for Codex, OpenCode from meridian-edge/meridian-edge-mcp. It costs 435 tokens per session, scanned A, original, MIT.

Project instructions for Meridian Edge, a service that combines prediction probabilities from several regulated markets. It provides access through an MCP server, an API, an agent endpoint, and a Python package.

In plain words
What is it for?
Getting consensus probabilities, finding differences between markets, viewing recent probability changes, listing tracked markets, and checking verified outcomes for sports, politics, and economic events.
Why use it?
It gives an agent the project context, connection details, authentication method, available data areas, and named operations so it can use the service correctly.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

meridian-edge-mcp AGENTS.md scanned grade A with 1 finding 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 10d 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.

Changes

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.
