mnemo-mcp: Instructions file for Codex

AGENTS.md

mnemo-mcp AGENTS.md is an instructions file for Codex, OpenCode from n24q02m/mnemo-mcp. It costs 2,990 tokens per session, scanned B, original, Apache-2.0.

Instructions for developing mnemo-mcp, a Python server that provides searchable AI memory tools. It combines keyword search with semantic search, which finds related meaning rather than only matching words.

In plain words
What is it for?
Working on memory storage and retrieval, configuring language and embedding models, running tests, checking code quality, and building the package.
Why use it?
It documents the commands and checks needed to set up, test, lint, type-check, build, and run the server.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions AGENTS.md.

This is n24q02m/mnemo-mcp's own configuration. It tells Codex and OpenCode how to work on mnemo-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mnemo-mcp configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is cd ../mcp-core && uv run --project scripts/e2e python -m e2e.driver <config-id>.

Reuse

Borrowing it

Nothing to install: this file belongs to n24q02m/mnemo-mcp. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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 B, and why

mnemo-mcp AGENTS.md scanned grade B 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 1mo 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.

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.
