Introducing Misar.Blog MCP Server: Publish Blog Posts with AI Agents

Gulshan Yadav — Thu, 14 May 2026 12:51:25 +0000

We just launched the Misar.Blog MCP Server — a Model Context Protocol server that lets AI agents publish and manage blog content on Misar.Blog directly.

What is it?

The Misar.Blog MCP Server exposes 20 tools that AI agents (Claude, Cursor, Cline, etc.) can use to:

Publish articles — create drafts, publish posts, schedule content
Manage series — create and organize multi-part article series
Analytics — query article views, engagement, and performance data
Comments & Reactions — moderate comments, fetch reactions
Newsletter — manage subscriber lists and campaigns
AI content generation — generate article content with AI assistance
Tag management — organize content with tags
Media uploads — attach images and files to posts

Quick Start

Connect via Smithery (no setup needed):

https://smithery.ai/servers/misar/misarblog-mcp

Or install locally:

npm install -g misarblog-mcp

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "misarblog": {
      "command": "npx",
      "args": ["-y", "misarblog-mcp"],
      "env": {
        "MISARBLOG_API_KEY": "your_api_key_here"
      }
    }
  }
}

Get your API key from misar.blog/settings/api.

Remote MCP URL

You can also connect directly via streamable HTTP:

https://www.misar.blog/api/mcp

With header: Authorization: Bearer <your_api_key>

Show DEV: MisarMail — Self-Hosted Email Infrastructure (Transactional, Marketing, Bulk)

Gulshan Yadav — Sat, 28 Mar 2026 12:33:01 +0000

What I Built

MisarMail is a self-hosted email infrastructure platform for sending transactional, marketing, and bulk email — without paying SendGrid, Mailgun, or Resend.

URL: https://mail.misar.io

Why I Built It

Every product I ship needs email — welcome emails, password resets, newsletters, bulk campaigns. Third-party email services add up fast. I wanted full control, zero per-email cost, and a simple API I own.

How It Works

REST API — POST /api/v1/send with your payload, done
SMTP relay — drop-in replacement for any SMTP config
Bounce handling — automatic bounce and complaint processing
Delivery tracking — opens, clicks, delivery status
Multi-domain — send from multiple domains and identities

Tech Stack

Self-hosted on a Hetzner VPS via Coolify. Mailcow under the hood for SMTP, custom API layer on top.

Try It

https://mail.misar.io

No third-party email spend. Full delivery control. API-first.

Show DEV: Free AI Cost Calculators for Developers — LLM Costs, Evaluations, Tokens, RAG

Gulshan Yadav — Fri, 27 Mar 2026 21:07:16 +0000

I built a set of 4 free AI calculators that run entirely in the browser — no signup, no API keys, no backend.

🔗 tools.misar.io

What's included

1. LLM Cost Calculator

Compare pricing across 14 models from OpenAI, Anthropic, Google, Mistral, Groq, and DeepSeek. Enter your token usage and get real-time daily, monthly, and annual cost projections. See all providers side-by-side sorted by cost.

2. AI Evaluation Scorecard

Assess AI system quality across multiple dimensions — accuracy, latency, cost efficiency, safety, and more. Get a weighted composite score to compare different AI approaches.

3. Prompt Token Estimator

Count tokens before making API calls so you know exactly what you'll pay. Supports multiple tokenizer models.

4. RAG Cost Estimator

Calculate the true cost of running retrieval-augmented generation pipelines — embedding costs, vector DB storage, retrieval queries, and generation costs combined.

Why I built this

Every AI team I've worked with wastes time on spreadsheets trying to estimate costs. These tools solve that with zero friction — open the URL, use the calculator, done.

Tech stack

Pure HTML/CSS/JavaScript — no frameworks, no dependencies
Runs entirely client-side in your browser
Mobile responsive
Free forever

Would love feedback from the community. What other AI calculators would be useful?
