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

paxaver-mcp 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 13d 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.

Purpose

This file defines the rules for AI agents that work in the Paxaver MCP repository.

Working rules

  • Follow system, developer, and user instructions first. Within repository guidance, more specific AGENTS.md files override parent guidance.
  • Run commands from this repository root. Use Node and pnpm versions from package.json.
  • Check git status --short before editing. Preserve user changes. Inspect existing code, consumers, and tests before adding a tool or dependency.
  • Read CONTRIBUTING.md. Internal documentation (architecture, authentication, authorization, tool reference, deployment, security model, test scenarios) lives in the private Paxaver monorepo under docs/paxaver-mcp/; it is intentionally not in this public repo. The sibling platform repository has its own instructions.

Project Overview

The Paxaver MCP server is an AI-facing adapter over the Paxaver school community platform. It implements the Model Context Protocol (MCP) on Cloudflare Workers with RS256 JWT validation, capability-first authorization, and Streamable HTTP transport.

The server is a thin adapter. It contains no business logic and never touches the database, Stripe, or email directly. Every action is delegated to the private Paxaver backend API over a Cloudflare service binding.

Repository Structure

  • apps/mcp/src/ — MCP server source code
    • api/ — Paxaver backend API client
    • auth/ — JWT validation and authorization
    • discovery/ — Well-known endpoints (RFC 9728, RFC 8414)
    • lib/ — Shared utilities (contracts, crypto, policy)
    • schemas.ts — Tool schema exports
    • server/ — MCP server implementation
    • tools/ — Tool handlers
    • transport/ — Streamable HTTP transport
  • apps/mcp/tests/ — Unit, protocol, and smoke tests

Internal documentation is kept out of this repository: it lives in the private Paxaver monorepo under docs/paxaver-mcp/ (architecture.md, authentication.md, authorization.md, tools.md, deployment.md, security.md, compatibility.md, migration.md, TEST_SCENARIOS.md, CONTEXT-MAP.md, privacy/compliance.md).

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.
