Overview

Description from the maker (original English)

Private, portable memory and reusable skills for AI agents.

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

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

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://sutra-c3or.onrender.com/mcp

Run this in your terminal

claude mcp add --transport http sutra https://sutra-c3or.onrender.com/mcp

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "sutra": {
      "url": "https://sutra-c3or.onrender.com/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": {
    "sutra": {
      "type": "http",
      "url": "https://sutra-c3or.onrender.com/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.

Compared with others in Search & AI memoryi

  • More stars than 0% of the other 5692 servers in this category
  • Published to the registry more recently than 38% of the other 5692 servers in this category
  • Basic checks equal to or better than 100% of the other 5692 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 Sutra 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 (1.0.1) reached the registry 2 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: Context7, Codebase Memory, Exa

Connect Sutra

https://sutra-c3or.onrender.com/mcp
ConnectionUse whenWhat happens
OAuth 2.1Your client supports remote MCP authorization.The client opens Sutra in your browser, requests consent, and stores its grant.
API keyYour client expects an Authorization header.You create a dedicated, revocable key in Sutra and store it with the client's secret mechanism.
  1. Create a Sutra account.
  2. Choose a client configuration below.
  3. Complete OAuth or enter a dedicated API key when prompted.
  4. Confirm the client discovers 10 tools.
  5. Try: Use Sutra to list my project clusters. Ask before saving anything.

[!IMPORTANT]

Never put a real Sutra API key, OAuth token, memory export, or password in a checked-in configuration file.

Choose Your Client

Cursor OAuth

Install this repository as an Agent Plugin, or add the following to ~/.cursor/mcp.json:

{

"mcpServers": { "sutra": { "url": "https://sutra-c3or.onrender.com/mcp" } } }

Connect the server and complete Sutra's browser authorization flow.

OpenCode OAuth + DCR + PKCE

Merge clients/opencode.json into your global or project opencode.json:

{

"$schema": "https://opencode.ai/config.json", "mcp": { "sutra": { "type": "remote", "url": "https://sutra-c3or.onrender.com/mcp", "oauth": {} } } }

Authorize and inspect the connection:

opencode mcp auth sutra

opencode mcp list

VS Code and GitHub Copilot API key

Copy clients/vscode-mcp.json to .vscode/mcp.json, or merge it into your user MCP configuration:

{

"inputs": [ { "id": "sutra-api-key", "type": "promptString", "description": "Sutra API key", "password": true } ], "servers": { "sutra": { "type": "http", "url": "https://sutra-c3or.onrender.com/mcp", "headers": { "Authorization": "Bearer ${input:sutra-api-key}" } } } }

Start Sutra from the MCP configuration editor. VS Code requests the key through a masked input instead of storing it in the file.

Claude Code API key

Use the Sutra CLI for guided setup:

npm install -g @shivnathtathe/sutra-cli

sutra connect claude-code

The CLI requests a dedicated key and safely writes the supported local configuration. It does not send your key to this repository.

Need another agent? Sutra publishes current instructions for all 22 tested integrations.

Confirmed Compatibility

11 web agents use OAuth. 11 CLI and desktop agents use dedicated API keys. Product names and marks belong to their respective owners.

Tool Surface

Sutra exposes 10 typed tools. Read operations retrieve only the context needed for the current request. Write, upload, and export operations require deliberate user intent.

Context and memoryAccessPurpose
read_contextReadLoad the user's shared identity context.
search_memoryReadFind targeted memories by keyword.
list_clustersReadDiscover available project clusters.
get_clusterReadLoad one known project cluster.
write_observationWriteSave one durable preference, decision, correction, or fact.
export_allExportExport all user memories for data portability.
Reusable skillsAccessPurpose
list_skillsReadDiscover skills explicitly enabled by the user.
get_skillReadLoad an enabled skill and its resource index.
get_skill_resourceReadRead one resource referenced by an enabled skill.
upload_skillWriteUpload a new immutable skill version after explicit authorization.

Data Boundaries

Sutra doesSutra does not
Stores observations deliberately saved by a user or authorized agent.Copy every conversation from a connected client.
Isolates unrelated context in named project clusters.Share one cluster with every request automatically.
Shows the source agent, tags, and activity for stored memories.Hide writes inside an opaque client profile.
Supports revocable OAuth grants and per-client API keys.Require one permanent credential across all agents.
Provides an explicit full export for portability.Lock user memory to one AI vendor.

Read Security and data boundaries, the Privacy Policy, and the Terms of Service before connecting sensitive workflows.
