What is Business-Central-MCP-Integration CLAUDE.md?

Development instructions for a work-in-progress Microsoft Dynamics 365 Business Central MCP server. Business Central is Microsoft's business-management software, and MCP is a way for AI tools to interact with software through a standard interface.

Use them to build and test the BC MCP server, locate version-specific references, work with its test environments, and follow its implementation rules.

They give contributors the project's source locations, test environments, build commands, and strict development expectations. This reduces mistakes when working across Delphi, Free Pascal, and decompiled reference code.

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	$0.06026	$0.06026
Opus 5	$0.03013	$0.03013
Sonnet 5	$0.01205	$0.01205
Haiku 4.5	$0.00603	$0.00603

Security

Grade A, and why

Business-Central-MCP-Integration 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 10d 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.

BC MCP Server v2

Development Philosophy

This project is NOT released and in active development:

Always choose the best solution, not the quickest compromise
Refactor aggressively when architecture is flawed
Fix problems properly, not with workarounds
No stubs, mocks, or skeleton implementations -- everything must be fully functional
No backwards compatibility concerns -- make breaking changes freely

Quick Start

Project Location

v2 source: U:/git/bc-mcp/
v1 reference (deprecated): C:\bc4ubuntu\Decompiled\bc-poc\
Decompiled BC28: U:/git/bc-mcp/reference/bc28/decompiled/
Decompiled BC27: C:\bc4ubuntu\Decompiled\ (various Microsoft.Dynamics.* directories)
Architecture spec: C:\bc4ubuntu\Decompiled\bc-poc\docs\superpowers\specs\2026-04-03-bc-mcp-v2-design.md

BC Test Environments

	BC28
URL	http://cronus28/BC/?tenant=default
Username	sshadows
Password	1234
Auth	NavUserPassword
License popup	Auto-dismissed
Protocol version	15041

Uses NavUserPassword authentication (not Windows/NTLM).

Essential Commands

cd U:/git/bc-mcp
npx tsc --noEmit                    # Type check
npx vitest run                       # Unit + protocol tests (292 tests)
npx vitest run --config vitest.integration.config.ts  # Integration tests against real BC28 (111 tests)
npm start                            # HTTP server on port 3000
npm run start:stdio-direct           # Direct stdio for Claude Desktop

Rules

Use Windows paths with forward slashes in bash
NEVER use 2>nul (creates undeletable files on Windows)
NEVER use emojis -- Windows rendering issues
Always run npx tsc --noEmit after changes
Run integration tests after any protocol-level change
ESM project -- use .js extensions in all imports

Protocol Verification Procedure

CRITICAL: Always verify protocol behavior against decompiled BC source, not v1 code.

V1 had several incorrect assumptions (per-page connections, SaveValue not echoing, etc.). When implementing or debugging any BC protocol interaction:

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.
