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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02631 | $0.02631 |
| Opus 5 | $0.01316 | $0.01316 |
| Sonnet 5 | $0.00526 | $0.00526 |
| Haiku 4.5 | $0.00263 | $0.00263 |
Grade A, and why
MCP-Open-Discovery-with-AMQP copilot-instructions.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 11d 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.

Use this when coding in this repo. It reflects the code as-is and the workflows we actually use.
Architecture you need to know
- Server:
mcp_open_discovery_server.jscreates one McpServer, registers tools/resources/prompts, and starts transports viatools/transports/core/transport-manager.js. - Registry & hot‑reload:
tools/registry/index.js(CoreRegistry + HotReloadManager + mcp‑types adapter). Tool modules export{ tools, handleToolCall }; the registry callsserver.registerTool(...)for you. - Transports:
- stdio:
tools/transports/core/stdio-transport.js - http (SSE):
tools/transports/core/http-transport.jswith health and optional OAuth - amqp:
tools/transports/amqp-transport-integration.js(server wrapper; base helpers intools/transports/base-amqp-transport.js)
- stdio:
- Data & security:
- Memory/CMDB (SQLite + encryption):
tools/memory_tools_sdk.js - Credentials (encrypted + audit):
tools/credentials_tools_sdk.js,tools/credentials_manager.js - Discovery tools:
tools/{network,nmap,snmp,proxmox,zabbix}_tools_sdk.js
- Memory/CMDB (SQLite + encryption):
How to run and test (Windows/PowerShell)
- Docker (preferred):
./rebuild_deploy.ps1 - Local dev (Node >= 23):
npm start(uses TRANSPORT_MODE defaults). Scripts:start-stdio,start-http,start-amqp,start-all - Health:
npm run health→ http://localhost:3000/health - Quick tests (see
testing/):node testing/test_direct_sdk_registration.js(SDK register/connect smoke)node testing/test_mcp_bidirectional_routing.js(transport)node testing/audit_mcp_compliance.js(protocol checks)
Implementing tools (pattern that works here)
- File:
tools/<category>_tools_sdk.js - Export:
tools: [{ name, description, inputSchema, annotations? }](Zod or JSON Schema)async function handleToolCall(name, args)→ switch byname; return structured object. Simple objects are auto‑wrapped by registry.
- Don’t call
server.registerToolin modules; registry does it:tools/registry/index.js. - Use descriptive names with prefixes (e.g.,
nmap_tcp_connect_scan,snmp_device_inventory).
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.

MCP-Open-Discovery-with-AMQP copilot-instructions.md is an instructions file published in the GitHub repository nagual69/MCP-Open-Discovery-with-AMQP (2 stars, last pushed 5mo ago), licensed MPL-2.0. It adds 2,631 tokens to every session, about $0.0132 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
