In plain words

Use it when modifying the server, managing dependencies with uv, or following its typing, formatting, linting, and documentation rules.
Why use it?
It tells coding agents which files and development practices to follow, helping prevent inconsistent code or failed checks.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is ambiental-media/jor-mcp's own configuration. It tells Codex and OpenCode how to work on jor-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 jor-mcp configures →

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

jor-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 4d 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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

- **Subprocesses:** Never use `os.system` or `subprocess.run(..., shell=True)` with unvalidated input to prevent shell injection vulnerabilities.

AI Agent Instructions for jor-mcp

Welcome, AI Agent. This AGENTS.md file defines the standard operating procedures, commands, and code style guidelines for the jor-mcp project. You must strictly adhere to these instructions to ensure high-quality, safe, and consistent contributions to this repository.

Project Context

  • Name: jor-mcp
  • Purpose: A Model Context Protocol (MCP) server for Ambiental Media, searching journalism content across WordPress and GitHub.
  • Language: Python >= 3.12
  • Core Libraries: fastmcp, uvicorn, httpx (async), pyjwt, opentelemetry
  • Dependency Manager: uv
  • Consent Portal: portal/ (Next.js static export, npm), deployed to GCS behind the load balancer. It is a separate npm project: make check never invokes Node.

Prerequisite: Development Standards

Before making any changes, you must read and adhere to the rules defined in CONTRIBUTING.md. This includes:

  • Language Constraint: All technical communication (commit messages, PR descriptions, code comments, variable names, and documentation) MUST be in English. (The only exception is the @mcp.tool() description parameter, which must remain in Portuguese).
  • Using uv for all dependency management and task execution.
  • Enforcing strict typing, linting (ruff), and formatting.
  • Ensuring all new code maintains the 90% test coverage minimum.
  • Validation: After writing or modifying code, use the make check command to run all linters, formatters, type checkers, and tests at once. Do not propose a Pull Request or consider a task finished until make check passes completely.
  • Portal validation: Run make check-portal after any change under portal/; it installs, audits, tests, and builds both deployment profiles. make check-docs guards living documentation.
  • Documentation Sync: For every proposed change, you MUST review and update the docs/ directory to ensure it accurately reflects the new code, new environment variables, or new architecture. Never submit code changes without checking if the technical, deployment, or usage documentation needs updating.

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.
