Transport: Streamable HTTP
Category: Search & AI memory

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.

You need

Runs in the cloudNothing to install; it connects over the internet

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:

Open Settings → Connectors
Press Add custom connector
Paste the address below and press Add
If it asks you to sign in, sign in with the maker

https://agentstackdirectory.com/mcp

Run this in your terminal

claude mcp add --transport http agent-stack-directory https://agentstackdirectory.com/mcp

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "agent-stack-directory": {

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

    }
  }
}

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:

Open ChatGPT on the web → Settings → Connectors (Apps)
Press Create or Add (some plans need Developer mode under Advanced first)
Paste the address below, give it a name and save

Common questions

Is Agent Stack Directory 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 (0.1.0) reached the registry 19 days 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: Context7, Codebase Memory, Exa

Agent Stack Directory: MCP server and open dataset

An open dataset of infrastructure tools for AI agents (cloud browsers, sandboxes, memory, search APIs, email, integrations, payments, voice, observability, frameworks and auth) plus a small MCP server so AI coding tools can query it while you build.

Remote endpoint: https://agentstackdirectory.com/mcp (Streamable HTTP, stateless, read-only, no key)
Live data: https://agentstackdirectory.com/data.json
Snapshot in this repo: data/ (JSON and CSV)
Website: https://agentstackdirectory.com/mcp/

Tools

Tool	Input	Returns
`search_tools`	`query?`, `category?`, `open_source?`, `limit?` (1 to 50, default 10)	Matching tools ranked by keyword match
`get_tool`	`tool` (slug or name)	Summary, official site, open-source flag, last link check, alternatives in the same category
`compare`	`tools` (2 to 4 slugs or names)	Side-by-side table, notable differences, head-to-head page URL when one exists
`list_categories`	none	Every category with key, description and tool counts

Every tool is read-only. Results come back as readable text plus structuredContent JSON.

Example prompts:

"Which sandboxes for running agent code are open source?"
"Compare E2B and Daytona."
"What are the alternatives to Browserbase?"

Listed in the official MCP Registry as com.agentstackdirectory/agent-stack-directory. Server card: https://agentstackdirectory.com/.well-known/mcp/server-card.json

Install (remote, nothing to run locally)

Claude Code

claude mcp add --transport http agent-stack-directory https://agentstackdirectory.com/mcp

Cursor

.cursor/mcp.json in your project, or ~/.cursor/mcp.json for all projects:

"mcpServers": { "agent-stack-directory": { "url": "https://agentstackdirectory.com/mcp" } } }

VS Code

.vscode/mcp.json in your workspace:

"servers": { "agent-stack-directory": { "type": "http", "url": "https://agentstackdirectory.com/mcp" } } }

Or from a terminal:

code --add-mcp '{"name":"agent-stack-directory","type":"http","url":"https://agentstackdirectory.com/mcp"}'

Install (local, stdio)

Needs Node 18 or newer. npx builds the server from this repository on first run.

Claude Code

claude mcp add agent-stack-directory -- npx -y github:gmansystems/agent-stack-directory

Cursor

"mcpServers": { "agent-stack-directory": { "command": "npx", "args": ["-y", "github:gmansystems/agent-stack-directory"] } } }

VS Code

"servers": { "agent-stack-directory": { "type": "stdio", "command": "npx", "args": ["-y", "github:gmansystems/agent-stack-directory"] } } }

From a clone

git clone https://github.com/gmansystems/agent-stack-directory

cd agent-stack-directory npm install node dist/stdio.js

Environment variables (optional):

Variable	Default	Purpose
`AGENT_STACK_DATA_URL`	`https://agentstackdirectory.com/data.json`	Where to fetch the dataset
`AGENT_STACK_DATA_FILE`	unset	Read a local JSON file instead, for offline use, e.g. `data/agent-stack-directory.json`

The stdio server caches the dataset in memory for 10 minutes and keeps serving the last good copy if a refresh fails.

Dataset

data/agent-stack-directory.json holds categories and listings. Each listing has:

Field	Meaning
`slug`	Stable identifier, used in directory URLs
`name`	Product name
`url`	Official site
`category`	Category key (see `categories`)
`summary`	One plain sentence on what it does, written from the vendor's own site
`tagline`	The vendor's own tagline
`open_source`	`true` when the product is marked open source
`added`	Date added to the directory
`verified`	Date the official link was last checked

CSV copies: data/agent-stack-directory.csv and data/categories.csv. Refresh the snapshot with npm run snapshot.

Sponsorship never changes the data or the search ranking. The dataset has no sponsored fields.

Development

npm install

npm test # unit tests plus MCP client tests over stdio and Streamable HTTP npm run test:remote # live check of https://agentstackdirectory.com/mcp with the MCP client npm run build:worker # bundle src/worker.ts for the Cloudflare Pages Function

Layout:

src/core.ts: data loading and the tool logic, no I/O
src/server.ts: MCP server definition (official TypeScript SDK)
src/stdio.ts: stdio entry point (agent-stack-directory-mcp bin)
src/worker.ts: stateless Streamable HTTP handler for Cloudflare Workers or Pages Functions

To host your own remote copy on Cloudflare, bundle src/worker.ts and call handleMcpRequest(request, loader) from a Worker.
