What is mcp-erpnext AGENTS.md?

Repository instructions for AI coding agents working on an ERPNext integration project. ERPNext is business-management software, and the project provides an MCP server so agents can work with its records and workflows.

Use it when developing, testing, or reviewing the Casys-AI ERPNext MCP server, including its TypeScript server and React-based interface.

It gives agents the project's structure, conventions, build commands, and testing guidance so their changes fit the codebase.

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	$0.07520	$0.07520
Opus 5.5	$0.03008	$0.03008
Sonnet 5.5	$0.01504	$0.01504

Security

Grade A, and why

mcp-erpnext 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 21d 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.

Project Overview

MCP server that lets AI agents operate an ERPNext/Frappe instance: documents, workflows, and interactive UI viewers. Published as @casys/mcp-erpnext on npm (Node bundle) and JSR (Deno).

Project Structure & Module Organization

Entry points: mod.ts (JSR public API), server.ts (MCP server — stdio + HTTP).
Config: deno.json is the primary config (version, tasks, import map). src/ui/package.json manages UI-only npm deps (Preact, Vite, Recharts).
Source code: all under src/. Server-side TypeScript uses Deno conventions; UI viewers use Vite/Preact with standard npm imports.
Tool categories: one file per category under src/tools/ (sales.ts, inventory.ts, accounting.ts, etc.). All registered in src/tools/mod.ts.
Tests: colocated with source files (Deno convention) — foo.ts / foo_test.ts. Not all modules have tests yet; the convention is the target, not a guarantee.
UI viewers: each viewer is a standalone Preact app under src/ui/{viewer-name}/, bundled to a single HTML file. Built output goes to src/ui/dist/ (gitignored but included in published artifacts via deno.json publish config).
Kanban: src/kanban/ contains types, definitions, field-utils, and per-DocType adapters in adapters/.
Cache: src/cache/ — pluggable Cache interface, MemoryCache/ NoopCache implementations, app-wide singleton.
Runtime adapters: src/runtime.ts (Deno) and src/runtime.node.ts (Node.js) — the build script swaps them.
Scripts: scripts/build-node.sh produces the npm bundle; scripts/release-guard.mjs is the publish guard (versions, tag ref, npm dist-tag, latest never moves backwards); scripts/align-next-dist-tag.mjs decides whether a stable release realigns next (an unreadable npm registry leaves next untouched); scripts/third-party-notices.mjs generates/checks THIRD_PARTY_NOTICES.txt. Their tests (scripts/*_test.ts) run with deno task test:scripts.
Docs: docs/ contains roadmap, known issues, and coverage notes.
Keep UI-only deps in src/ui/package.json; do not add them to deno.json. Conversely, server-side deps go in the deno.json import map.

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.
