Overview

Description from the maker (original English)

Hosted MCP: search, fetch, compress, dedup, budget, memory, pipelines. Not an LLM proxy.

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: Search & AI memory
  • You need to fill in: Authorization

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.
  • You fill in yourself: Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

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

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http smartgate https://smartgate.network/api/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "smartgate": {
      "url": "https://smartgate.network/api/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

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": {
    "smartgate": {
      "type": "http",
      "url": "https://smartgate.network/api/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

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.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

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

Values you fill in

  • Authorization secret required HTTP header
    Bearer sk_live_ key from https://smartgate.network Dashboard → API Keys

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

Common questions

Is SmartGate 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?

You need to fill in: Authorization

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 (1.0.0) reached the registry 10 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

SmartGate

AI Intelligence Layer — not another assistant or LLM proxy.

Official [SmartGate](https://smartgate.network) plugin for Cursor, Claude Code, claude.ai, and Cowork.

SmartGate is the intelligence layer between AI and the world — helping you research, understand, remember, and act before runaway tool traffic becomes a surprise invoice.

On the surface: Smart Research, decisions, knowledge, and monitoring — no MCP required. Under the hood: an MCP-native algorithmic gateway with five capabilities (Research, Context, Memory, Control, Pipeline) powered by seven smart_* primitives. Human interface (Web) + agent interface (MCP/API). Not a chatbot, search app, or model router. The host model stays on the client.

Plugin mark for Cursor Marketplace is the 1:1 shield assets/logo.png. The banner is the official site OG card. The research demo is the same GIF as the homepage.

What is SmartGate MCP

Don't rebuild research infrastructure for every agent. Connect once over Streamable HTTP; the gateway fetches, searches, compresses, deduplicates, remembers, and hard-caps tool traffic before it reaches your model provider.

CapabilityWhat the agent doesProduct
ResearchFind sources, then read pages as MarkdownTraffic Customs
ContextDedup overlapping hits, then compressToken Control
MemoryPersist and recall team facts across sessionsFeatures
ControlCheck, count, and cap token budgetToken Control
PipelineRun research / read / remember as one jobTools

Install

Mint a key at Dashboard → API Keys (sk_live_…). Never paste the key into chat or commit it.

Official MCP Registry name: network.smartgate/smartgate. Same endpoint: https://smartgate.network/api/mcp. The listing is metadata only — you still need the Dashboard Bearer key.

Cursor
  1. Install SmartGate from the Cursor Marketplace, or import this repo under Cursor Dashboard → Plugins → Team Marketplaces → Import from Repo: https://github.com/smartgate-network/smartgate-workflows
  2. Open Plugins → SmartGate → Configure and set SMARTGATE_API_KEY
  3. Restart Cursor (or reload the window) so the MCP handshake runs again
Claude (claude.ai / Cowork / Claude Code)
  1. Add SmartGate from Anthropic's directory, or load this repo locally: claude --plugin-dir .
  2. When Claude prompts for plugin configuration, set SMARTGATE_API_KEY. In Claude Code you can also run /plugin configure @smartgate
  3. Confirm the connector: on claude.ai / Cowork use the plugin's Connectors tab; in Claude Code run /mcp and look for plugin:smartgate:smartgate
Gemini CLI
gemini extensions install https://github.com/smartgate-network/smartgate-workflows

Set SMARTGATE_API_KEY when the CLI prompts. Manifest: gemini-extension.json.

OpenClaw

Install the ClawHub skill, then add the hosted MCP:

openclaw skills install @smartgate.network/smartgate

Connect: Settings → MCP → Add server (Streamable HTTP, https://smartgate.network/api/mcp, Authorization: Bearer ${SMARTGATE_API_KEY}). Skill source: skills/smartgate/SKILL.md.

Hermes

From the Hermes MCP catalog:

hermes mcp install smartgate

Paste the Dashboard sk_live_… key when prompted (MCP_SMARTGATE_API_KEY).

Or add the hosted server in ~/.hermes/config.yaml and the key in ~/.hermes/.env:

mcp_servers:

smartgate: url: "https://smartgate.network/api/mcp" headers: Authorization: "Bearer ${SMARTGATE_API_KEY}" X-SmartGate-Agent-Platform: hermes

Skill (ClawHub):

hermes skills search smartgate --source clawhub

hermes skills install clawhub/smartgate.network/smartgate

Or add this repo as a skill tap: hermes skills tap add smartgate-network/smartgate-workflows.

AutoGPT

From AutoGPT's hosted MCP catalog, select SmartGate and paste the Dashboard sk_live_… key as the access token. Paste the key only — the client adds Bearer.

Or add an MCP Tool block: URL https://smartgate.network/api/mcp, auth Bearer, access token = Dashboard API key.

Zed

Settings → AI → MCP Servers → Add Server → Add Remote Server:

{

"context_servers": { "smartgate": { "url": "https://smartgate.network/api/mcp", "headers": { "Authorization": "Bearer ${SMARTGATE_API_KEY}", "X-SmartGate-Agent-Platform": "zed" } } } }

Or install from Zed MCP extensions if SmartGate is listed there.

VS Code / GitHub Copilot

Command Palette → MCP: Add Server → HTTP. URL https://smartgate.network/api/mcp. Set header Authorization = Bearer ${SMARTGATE_API_KEY}.

Or browse the gallery: Extensions view → search @mcp smartgate.

OpenCode

Add a remote MCP in OpenCode config:

{

"$schema": "https://opencode.ai/config.json", "mcp": { "servers": { "smartgate": { "type": "remote", "url": "https://smartgate.network/api/mcp", "oauth": false, "headers": { "Authorization": "Bearer {env:SMARTGATE_API_KEY}", "X-SmartGate-Agent-Platform": "opencode" } } } } }

Goose

Add a Streamable HTTP extension: URL https://smartgate.network/api/mcp, header Authorization: Bearer ${SMARTGATE_API_KEY}, X-SmartGate-Agent-Platform: goose. Skill source: skills/smartgate/SKILL.md.

Kilo Code

Install from the Kilo Marketplace, or connect the hosted MCP the same way as Cline — see llms-install.md.

Crush

Add a remote Streamable HTTP MCP in Crush config. URL https://smartgate.network/api/mcp, header Authorization: Bearer ${SMARTGATE_API_KEY}.

Cherry Studio

Settings → MCP → MCP Servers → Add. Import from JSON (type must be streamableHttp) or Quick Create → Streamable HTTP:

{

"mcpServers": { "smartgate": { "type": "streamableHttp", "url": "https://smartgate.network/api/mcp", "headers": { "Authorization": "Bearer ${SMARTGATE_API_KEY}" } } } }

Enable the server, then Work → Agent → Edit → MCP and bind it.

AnythingLLM

Settings → Agent Skills, or edit plugins/anythingllm_mcp_servers.json (type is streamable, not streamable-http):

{

"mcpServers": { "smartgate": { "type": "streamable", "url": "https://smartgate.network/api/mcp", "headers": { "Authorization": "Bearer ${SMARTGATE_API_KEY}" } } } }

Reload MCP servers in the UI, start SmartGate, then enable its tools for the workspace.

Other MCP clients (LibreChat, Open WebUI, Dify, Langflow, Flowise, n8n)

Any host that supports remote Streamable HTTP can connect with:

  • URL: https://smartgate.network/api/mcp
  • Header: Authorization: Bearer ${SMARTGATE_API_KEY}
  • Official Registry name: network.smartgate/smartgate

First run

After the MCP server shows as connected, try:

Check my SmartGate token allowance with smart_budget_guard action=check.
smart_fetch https://smartgate.network/docs/tools then summarize Token Control, Traffic Customs, and Audit.
Remember: our staging API rate limit is 100 req/min

Live tools/list schemas (purpose, params, returns) come from the hosted server, not this repo. Names are smart_* — there is no smartgate_compress_context. Full reference: Docs → Tools.

Tools (reviewer cheat sheet)

Every tool returns a JSON string. Parse it before synthesizing. Do not invent page content.

ToolRequiredOptionalReturns
smart_searchquerymax_results (1–50, default 10)Search hits (results[].url, snippet)
smart_fetchurl (http/https)timeout (default 30s)Page markdown, title, url
smart_deduptexts (string[])threshold (0–1, default 0.9)Kept / removed indices or deduped texts
smart_context_gatetextratio (default 0.5), purposecompressed, ratio, token counts
smart_budget_guardaction: check \count \recordtext / tokens by actionAllowance, usage, or record ack
smart_memoryaction: add \search \get \deletetext (add), query (search), memory_id (get/delete)Shape depends on action
smart_pipetemplate or stepsquery, url, textPer-step results. Templates: research, read, remember. Not for a single step.

Configure

Cursor Marketplace: Plugins → SmartGate → Configure → SMARTGATE_API_KEY. Cursor reads mcp.json (${SMARTGATE_API_KEY}).

Claude directory / Claude Code: /plugin configure @smartgate → SMARTGATE_API_KEY. Claude reads .mcp.json (${user_config.SMARTGATE_API_KEY}). Do not commit a real key.

Manual / reviewer fallback (only if you are not using the plugin): merge this into ~/.cursor/mcp.json (user) or /.cursor/mcp.json (project), then restart Cursor. Replace the placeholder. If the plugin is also installed, delete this block so tools are not duplicated.

Claude Code / claude.ai fallback (only if the plugin is not installed). Same endpoint, Claude's http type, and ${user_config.SMARTGATE_API_KEY} in the plugin copy of .mcp.json:
