Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs an external command platform/mcp/smoke-test.mjs:20, platform/mcp/server.mjs:101, plugins/aaj-marketing-skills/platform/mcp/server.mjs:101

const listed = spawnSync(process.execPath, [SERVER, "--engines"], { encoding: "utf8" });

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

describe

describe_engine

Shows one engine's input schema: required fields, units, alternative shapes, and a worked example. Engines reject bad input rather than guessing.

engine

run_engine

Runs an AAJ engine and returns its verdict. Give `input` as an object of the engine's fields. Omit `input` to run the engine's built-in worked example. Engines are deterministic, offline, and validate their input — a wrong unit is reported as an error, not absorbed into a confident answer.

engines

list_engines

Lists every AAJ marketing engine: its id, the question it answers, and its category. Engines cover unit economics, pipeline forecast, budget allocation, retention, A/B significance, SEO/GEO scoring, ad spend and pricing.

skill

get_skill

Returns the full method for one skill: when to use it, the steps, the quality bar, and how to run its engine if it has one.

skills

search_skills

Finds AAJ marketing skills by the problem they solve — 'churn is rising', 'we're launching next month', 'not showing up in AI answers'. Returns matching methods and marks which have a runnable engine.

AAJ Marketing Engines — questions

Answers built from our own checks of this server.

What can AAJ Marketing Engines do?

It exposes 5 tools, read directly from the server on our last check. Among them: describe_engine, get_skill, list_engines, run_engine, search_skills. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is AAJ Marketing Engines working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 120 ms. The bar chart above shows every period we have measured.

How do I connect AAJ Marketing Engines?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does AAJ Marketing Engines need an API key?

No. AAJ Marketing Engines completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is AAJ Marketing Engines?

It answers our handshake in 120 ms on average, which is faster than 89% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is AAJ Marketing Engines open source?

The code is open source: it is published under the MIT licence, written in JavaScript and 1 stars on GitHub. The licence covers the code in the repository, not the hosted service at aaj-engines-mcp.sarojkjha10.workers.dev, which runs on its operator's own terms.
