Overview

Description from the maker (original English)

Free MCP tools: the only MCP linter, health checks, cost estimation, and trust evaluation.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Clinics & health

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Works in Claude on the web, desktop and mobile:

  1. Open Settings → Connectors
  2. Press Add custom connector
  3. Paste the address below and press Add
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Add2https://…3
https://platform.crestsystems.ai/mcp

Run this in your terminal

claude mcp add --transport http agentic-platform https://platform.crestsystems.ai/mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "agentic-platform": {
      "url": "https://platform.crestsystems.ai/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "agentic-platform": {
      "type": "http",
      "url": "https://platform.crestsystems.ai/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Create2https://…3

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

  • More stars than 0% of the other 866 servers in this category
  • Published to the registry more recently than 12% of the other 866 servers in this category
  • Basic checks equal to or better than 100% of the other 866 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is Agentic Platform safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Mirobody, FHIR MCP Server, Google Health MCP

Agentic Platform

The only MCP linter that exists. Plus free governance scoring and cost estimation for AI agents.

Validate your MCP tool definitions, score your agent's system prompt on governance best practices (0-100), and compare costs across all major models. No API key needed.

Installation

Remote MCP Server (Hosted)

Add to your MCP client configuration:

{

"mcpServers": { "agentic-platform": { "url": "https://platform.crestsystems.ai/mcp" } } }

Claude Code
claude mcp add agentic-platform --transport http https://platform.crestsystems.ai/mcp
Docker
docker run -p 8080:8080 ghcr.io/andysalvo/agentic-platform:latest

Works with Claude Desktop, Claude Code, VS Code, Cursor, Cline, and any MCP-compatible client.

Governance

This platform operates under three core invariants:

  1. No Silent Inference -- no inferring or reinterpreting input without explicit documentation
  2. Auditability at the Decision Level -- every state change traceable to a decision
  3. Explicit Authority Transfer -- all commitments require explicit authorization

These apply to the platform itself, not just its users.
