DevLog MCP
DevLog MCP
Dies ist ein stdio-MCP-Server, der von KI-Codierungsagenten wie Codex und Claude Code erstellte Entwicklungstagebücher in einer bestehenden Notion Blog-Datenbank veröffentlicht. Der Agent ist für die Reflexion und das Verfassen des Inhalts verantwortlich, während dieser Server nur die Eingabevalidierung und die Notion-Speicherung übernimmt.
Anforderungen
Node.js 20 oder höher
Bestehende Notion Blog-Datenbank
Mit der Datenbank verbundene Notion-Integration

Installation und Build
npm install
npm test
npm run buildWenn Sie während der Entwicklung direkt ausführen, setzen Sie die Umgebungsvariablen in der aktuellen Shell. Dieses Projekt liest .env-Dateien nicht automatisch.
export NOTION_TOKEN="secret_..."
export NOTION_DATABASE_ID="..."
npm run devDer stdio-Server kommuniziert über JSON-RPC mit dem MCP-Client, daher werden bei der Ausführung im Terminal keine allgemeinen Hinweise ausgegeben.
Notion-Einrichtung
Erstellen Sie im Bereich „Integrationen“ von Notion eine interne Integration.
Verwenden Sie das Integrationstoken als
NOTION_TOKEN.Fügen Sie diese Integration im Verbindungsmenü Ihrer bestehenden Blog-Datenbank hinzu.
Suchen Sie die Datenbank-ID in der Datenbank-URL und verwenden Sie sie als
NOTION_DATABASE_ID.
Die Eigenschaftsnamen und -typen der Datenbank müssen wie folgt sein.
Eigenschaft | Notion-Typ | Standardwert |
| Titel | Pflichtfeld |
| Auswahl |
|
| Mehrfachauswahl | Leere Liste |
| Datum | Aktuelles Datum |
| Status |
|
Wenn die übergebenen Namen in den Optionen für Auswahl, Mehrfachauswahl und Status der bestehenden Datenbank nicht vorhanden sind, kann die Erstellung von Optionen je nach Notion-Berechtigungen und -Einstellungen eingeschränkt sein.
MCP-Tool
Der Server stellt ein einziges Tool namens publish_dev_log bereit.
type PublishDevLogInput = {
title: string;
category?: string;
tags?: string[];
publishedAt?: string;
status?: "published" | "draft";
content: string;
};Das im Textkörper unterstützte Markdown umfasst Überschriften der Stufen 1–3, Absätze, geordnete/ungeordnete Listen, Codeblöcke mit Begrenzung und Trennlinien.
Ein Beispiel für einen Aufrufeingabe ist wie folgt.
{
"title": "DevLog MCP 첫 구현",
"tags": ["MCP", "Notion", "TypeScript"],
"content": "# 오늘의 작업\nNotion 발행 도구를 구현했다.\n\n## 결정\n- MCP는 저장만 담당한다.\n- 회고 작성은 코딩 에이전트가 담당한다."

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden for behavioral disclosure. It only states the action (publish to DB) without mentioning idempotency, overwriting behavior, authentication needs, error conditions, or any side effects. This is insufficient for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence that efficiently conveys the core action and target. Every word is meaningful, and there is no fluff or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of output schema and annotations, and the presence of 6 parameters including an enum, the description does not provide enough context. It omits return values, error behavior, status effects, and operational prerequisites, leaving the agent underinformed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the baseline is 3. The description adds no additional meaning to any parameter beyond what the schema already provides (e.g., format hints, defaults, or usage context).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description states the verb 'publishes' and the resource 'completed development log' to the 'existing Notion Blog DB'. It is clear what the tool does, but with no sibling tools, differentiation is not applicable, so it scores 4 per rubric.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes '완성된' (completed), which implies the tool should be used when the development log is finished. However, it provides no explicit when-not-to-use instructions, prerequisites, or alternative tools, so guidance is only implied.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Scored across 1 tool
With only one tool, there is no possibility of confusion. The tool's purpose is entirely distinct by default.
A single tool cannot violate any naming pattern. The name 'publish_dev_log' follows a clear verb_noun convention.
A single tool for a server named 'DevLog MCP' feels thin. While it may serve a specific publishing need, the scope suggests more tools would be expected for full log management.
The tool only covers publishing completed logs. Missing basic operations like create, list, update, or delete dev logs, which are likely needed for a complete workflow.
