MCP Server Architect

by Arnstein Larsen

$19

The default MCP server is an API wrapper that dumps forty endpoint-shaped tools on the model and hopes — and the model gets confused, picks the wrong tool, and produces garbage that looks like a tool call

5 track routing, course design (ADDIE/SAM/Agile), teaching models, user growth, pricing, 2026.

Prompt Engineering Specialist

by Arnstein Larsen

$8.99

Production prompts grow by accretion — every failure gets another appended rule until the prompt is two thousand words of contradictions that the model navigates unpredictably

PostgreSQL Schema Architect

by Arnstein Larsen

$9.99

Schema mistakes are the most expensive kind — code refactors in days, but a wrong table design holds your data hostage for years

Codebase Explainer & Onboarding Mapper

by PubsProToolkit

Free

Point it at an unfamiliar or inherited repo and quickly understand it. Maps the architecture, identifies the key modules and entry points, traces the core end-to-end flows, surfaces the conventions and gotchas, and assembles a clean ONBOARDING.md — turning a strange codebase into a clear mental model fast. Built for the moment you join a project, take one over, or have to explain a repo before changing it.

Dependency Upgrade & Framework Migration Planner for AI Coding Agents

by Shandra

$55

Plans safe dependency upgrades and framework migrations for legacy applications with risk analysis, compatibility mapping, test planning, rollback strategy, and phased AI coding prompts.

🛡️ Model Resilience Linter

by JustHandled Labs

$12

Find the LLM integration code that will not survive a provider being pulled or going down. Flags single-provider lock-in with no alternative, calls with no failover branch, missing timeouts, retries with no limit or backoff, no degraded-mode default, and hardcoded endpoints with no alternate. This is about the model going away, not the model declining.

🗂️ Model Inventory Auditor

by JustHandled Labs

$13

Inventory every LLM model and provider your code depends on, the AI bill of materials, and flag the dependency risk. It lists each provider, model, and where it's used, then flags hardcoded model ids, single-provider dependency with no alternative, the same model referenced by different ids, model ids with no config or env indirection, and providers pinned in your manifests. Recognizes OpenAI, Anthropic, Google Gemini, and more from an editable list.

Senior-level Python code auditor for PEP 8, type safety, security vulnerabilities, and 3.10+ modernizations.

Technical Spec Writer

by Arnstein Larsen

$9.99

Write a technical spec that lets reviewers find the flaw before the code does — with data models, edge cases, and failure modes explicit.

Professional Go code auditor for performance optimization, concurrency safety, and modern 1.21+ idioms.

MCP Server Builder

by PubsProToolkit

Free

Scaffold a secure, spec-compliant MCP server from a description of the tools you want to expose. Sets up the official SDK (TypeScript or Python/FastMCP), defines tools/resources/prompts with strict JSON Schema, wires the right transport (stdio or Streamable HTTP), adds OAuth 2.1 for remote, and hardens against the MCP-specific footguns — prompt injection via tool output, token passthrough, over-broad scopes, command/path/SSRF injection, leaked secrets — before it ships. Returns a runnable skeleton plus a security checklist. Built by someone who's shipped production MCP servers.

Failure Mode Choreographer

by Al1as

$19.99

Architect designed system degradation and choreographed failure sequences to prevent chaotic breakdowns.

🚦 Pre Launch Safety Check

by JustHandled Labs

$13

Check your app for the security mistakes that leak data before you launch, explained in plain English. Flags API keys and secrets sitting in your code, a committed .env file, data with no login protecting it, database tables anyone can read, debug mode left on, wide-open sharing (CORS), hardcoded admin passwords, and public storage buckets. Built for non-technical founders shipping AI-built apps: every finding tells you what is wrong, why it matters, and how to fix it.

⚠️ Model Risk Register Generator

by JustHandled Labs

$12

Generate the model and vendor risk register a security lead asks for the morning after a model gets switched off. It scans your codebase for every model and provider, merges in the owner and data-residency notes you supply, and renders a register with provider, model, where it's used, fallback status, and an availability-risk rating per dependency. Markdown by default, CSV with a flag. Continuity-focused, not a compliance assessment.
