What is the Hashnode MCP Server?
Connect your Hashnode account to any AI agent to streamline your technical writing and blogging workflow. This MCP server allows you to interact with the Hashnode GraphQL API through natural language.
What you can do
- User Profiles — Retrieve detailed information about any Hashnode user by their handle using
get_user. - Publication Management — List all posts from a specific publication using its domain or hostname with
get_publication_posts. - Content Retrieval — Fetch full post content and metadata using slugs and hostnames via
get_post. - Publishing — Create and publish new blog posts with Markdown support and custom tags using
create_postdirectly from your conversation. - Editing — Update existing posts, titles, and content with
update_postwithout leaving your AI interface.
How it works
- Subscribe to this server
- Enter your Hashnode Personal Access Token
- Start managing your technical blog from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Technical Writers — Draft and publish articles directly from your AI-assisted writing environment.
- Developers — Share knowledge and updates on your Hashnode blog without switching contexts.
- Content Managers — Monitor publication feeds and update existing posts efficiently.

Why Pydantic AI?
Pydantic AI validates every Hashnode tool response against typed schemas, catching data inconsistencies at build time. Connect 5 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.
- —
Full type safety: every MCP tool response is validated against Pydantic models, catching data inconsistencies before they reach your application
- —
Model-agnostic architecture. switch between OpenAI, Anthropic, or Gemini without changing your Hashnode integration code
- —
Structured output guarantee: Pydantic AI ensures tool results conform to defined schemas, eliminating runtime type errors
- —
Dependency injection system cleanly separates your Hashnode connection logic from agent behavior for testable, maintainable code

Every tool call from Pydantic AI to the Hashnode MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I fetch profile details for any Hashnode user?
Yes! Use the get_user tool with the specific username handle. The agent will return their profile information, bio, and social links.
Does the publishing tool support Markdown formatting?
Absolutely. Both create_post and update_post accept contentMarkdown, allowing you to publish rich technical content with code blocks, headers, and links.
How do I list posts from a specific blog domain?
Use the get_publication_posts tool and provide the host domain (e.g., 'engineering.hashnode.dev' or your custom domain). It will return a list of recent posts from that publication.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Hashnode MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
