Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 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.

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.

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/ — Tool input schemas
    • server/ — MCP server implementation
    • tools/ — Tool handlers
    • transport/ — Streamable HTTP transport
  • apps/mcp/tests/ — Unit, protocol, and smoke tests
  • docs/ — Documentation

Tech Stack

  • TypeScript 6
  • Cloudflare Workers
  • Native fetch handler
  • jose (JWT validation)
  • Vitest (testing)
  • Wrangler 4

Build and Verification Commands

# Typecheck

# Lint

# Format check

# Build (dry-run)

# Security audit

Architecture Rules

  • The MCP server is a thin adapter. Do not add business logic.
  • Delegate all actions to the Paxaver backend API via service bindings.
  • Validate all trust-boundary inputs.
  • Handle failures explicitly with sanitized, user-safe error messages.
  • Do not expose secrets or private data in errors.

Authorization Model

  • RS256 JWT validation via JWKS from the centralized Paxaver auth worker.
  • Per-tool capability policy and role gating.
  • OAuth 2.1 Authorization Code + PKCE (S256) flow.

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.
