What is MCP-DB-Client copilot-instructions.md?

Project instructions for MCP-DB-Client, a framework that lets 1C:Enterprise business software expose tools and data through the Model Context Protocol. It describes the C++ network component, 1C business-logic module, and project conventions.

Use it when modifying the C++ DLL, 1C modules, HTTP and JSON-RPC handling, MCP tools, resources, prompts, or related build configuration.

It gives coding agents the repository's architecture, build rules, data formats, and thread-safety conventions so changes fit the existing framework.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01010	$0.01010
Opus 5.5	$0.00404	$0.00404
Sonnet 5.5	$0.00202	$0.00202

Security

Grade A, and why

MCP-DB-Client copilot-instructions.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 2mo 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.

http1c — MCP Server Framework for 1C:Enterprise

Project Overview

This is a framework for building Model Context Protocol (MCP) servers from 1C:Enterprise. It consists of two parts:

http-1c-dll/ — C++17 native DLL (1C Native API add-in) that handles MCP transport
http-1c-dp/ — Reference 1C data processor (BSL module) showing how to implement tools, resources, and prompts

The DLL handles protocol-level concerns (HTTP, JSON-RPC, sessions, security). The BSL module handles business logic (tool handlers, resource data, prompt generation).

Architecture

MCP Client ←→ Native DLL (C++ httplib) ←→ 1C:Enterprise (BSL via ExternalEvent)

POST /mcp — JSON-RPC MCP requests
GET /mcp — SSE notification stream
DELETE /mcp — Session termination

Key Conventions

C++ (http-1c-dll/src/)

Build: CMake + MSVC, NMake Makefiles, /MT static CRT, /utf-8
JSON: nlohmann/json (json.hpp)
HTTP: cpp-httplib (httplib.h)
1C API: Native API headers in include/ (AddInDefBase.h, IMemoryManager.h, types.h, ComponentBase.h)
String conversion: MB2WCHAR() / WCHAR2MB() for UTF-8 ↔ UTF-16
Thread safety: Separate mutexes per resource (toolsMutex, resourcesMutex, sessionMutex, etc.)
Events to 1C: ExtEvent(u"HttpServer", u"EventName", data)
Method registration: AddProcedure() / AddFunction() / AddProperty() with EN/RU names
Version: Defined in version.h as VERSION_SEMVER

BSL (http-1c-dp/http1c/Forms/Form/Ext/Form/Module.bsl)

Client-side handlers are &AtClient procedures (no Async/Await)
Server calls for metadata/computation use &AtServer functions
Component configuration via synchronous property assignments: Component.PropertyName = Value
Component methods via BeginCalling<MethodName> with NotifyDescription callbacks
DO NOT use reserved 1C names as local variables (Catalogs, Documents, Metadata, etc.)
JSON: JSONReader/JSONWriter + ReadJSON()/WriteJSON()
Error pattern: Try/Except → SendToolError() / SendResourceError() / SendPromptError()
Tool definitions: NewTool(), AddToolParam(), AddToolAnnotations(), SetToolOutputSchema()
Resource definitions: Structure with uri, name, description, mimeType
Prompt definitions: Structure with name, description, arguments array

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.
