abis-mcp: Instructions file for Claude Code

CLAUDE.md

abis-mcp CLAUDE.md is an instructions file for Claude Code from cijlabs/abis-mcp. It costs 689 tokens per session, scanned A, original, MIT.

Project instructions for an ABIS MCP server, a service that gives coding agents access to tools through the Model Context Protocol. They describe its commands, structure, security, and important files.

In plain words
What is it for?
Developing, reviewing, or debugging the ABIS MCP server, including its Node.js entry point, API wrapper, tools, database connection, and access controls.
Why use it?
They give an agent the project context needed to work safely and consistently, including how the server runs, authenticates requests, and stores data.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is cijlabs/abis-mcp's own configuration. It tells Claude Code how to work on abis-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 abis-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

abis-mcp CLAUDE.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 7d 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.

ABIS MCP Server

Overview

MCP (Model Context Protocol) server for ABIS. 37 tools v3.5.0, dual-mode SSE + stdio, raw Node.js (ESM), deployed on Railway.

Commands

npm install        # Install dependencies
npm run dev        # Start with --watch (port 3100)
node index.js      # Start MCP server (stdio mode)

Architecture

  • Transport: Dual-mode — SSE (HTTP for Railway) + stdio (for Claude Desktop/Code)
  • Backend: Proxies to Railway FastAPI at RAILWAY_URL
  • Persistence: MongoDB Atlas via MONGODB_URI
  • Auth: ABIS_ADMIN_KEY sent as X-Admin-Key (GET) and X-API-Key (POST)

Security

  • Per-tool auth gates (free/pro/admin tiers)
  • Input validation with 11-model allowlist
  • Per-key rate limits: free=30, pro=120, admin=300 req/min
  • Hono CVE patched

Key Files

index.js           # Entry point, registers all 37 tools
config.js          # Environment variable exports
db.js              # MongoDB connection, index creation
api.js             # Railway API fetch wrapper (10s timeout)
tools/*.js         # One file per tool (37 files)

MongoDB Collections

  • mcp_sessions — Session starts (ambient_status)
  • mcp_message_scores — Scored messages with drift + whisper level
  • mcp_conversation_logs — Conversation turns with drift scores
  • mcp_benchmark_triggers — Benchmark run triggers

Known API Quirks

  • /drift/all returns empty — use /aggregate instead
  • /scorecard/all returns no_data — use /scorecard/latest/{model}
  • POST endpoints require X-API-Key; GET endpoints use X-Admin-Key (same key value)
  • /version-changes returns 404 (not deployed)

Drift Thresholds

  • <0.40: stable (green)
  • 0.40-0.65: monitor (yellow)
  • 0.65-0.90: alert (red)

  • 0.90: critical — likely baseline issue, not genuine drift

Monitored Models (11)

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.
