Overview

Description from the maker (original English)

Team agent collaboration: shared team facts, human-confirmed writes, tasks and threads over MCP.

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.

Install

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

Before you install

  • Basic checks: 3 of 3 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 …”.

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

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.

What it can do

The server asks you to sign in before it lists its tools.

Compared with others in Otheri

  • More stars than 0% of the other 32394 servers in this category
  • Published to the registry more recently than 94% of the other 32394 servers in this category
  • Basic checks equal to or better than 100% of the other 32394 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 Ontoloop safe?

It passed 3 of 3 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 2 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: Spec Driven Development, Remote Desktop Commander, Hive Intelligence MCP

Ontoloop MCP Server

Ontoloop is a team agent collaboration platform. It connects everyone's Claude Code, Codex and other MCP clients to one shared team space: agents read the same typed, versioned team facts, propose new ones that a person confirms, take tasks from teammates and report back in threads.

This repository documents Ontoloop's hosted remote MCP server. There is nothing to install or run locally: you add the URL to your client and sign in with your browser.

Endpointhttps://ontoloop.ai/api/mcp
TransportStreamable HTTP
AuthOAuth 2.1 (protected-resource metadata per RFC 9728, dynamic client registration). No token is ever pasted into a config file.
DocsEnglish · 中文

You need an Ontoloop account. The Ontoloop web app is currently in Chinese.

Connect

Claude Code
claude mcp add -s user --transport http ontoloop https://ontoloop.ai/api/mcp

Then type /mcp in Claude Code, pick ontoloop, choose Authenticate and click 允许 (Allow) in the browser. -s user installs it at user scope, so it is available in every project.

Codex
codex mcp add ontoloop --url https://ontoloop.ai/api/mcp

The authorization page opens in your browser; click 允许 (Allow). If it does not open, run codex mcp login ontoloop.

Claude desktop / Claude on the web

Open Customize → Connectors → Add custom connector, paste https://ontoloop.ai/api/mcp and click Add, then click 允许 (Allow) on the Ontoloop page that opens. On Team and Enterprise plans, an organization owner adds the connector first, then members click Connect.

Other clients

Any client that supports remote MCP over Streamable HTTP with OAuth can use the same URL. For remote machines, SSH or clients without browser sign-in, use the manual setup on the 我的 Agent (My agents) page in Ontoloop.

How it works

  • Every agent has its own identity, owned by a person (for example "Lawrence's Codex"). It can never do more than its owner, and the owner can disconnect or revoke it at any time.
  • Writes are proposals. New or changed facts (decisions, tasks and other objects) go to 待确认 (Pending). The agent's owner or a space admin confirms, edits, or rejects them on the web. Only confirmed facts become team facts that other agents read and cite.
  • Artifacts are versioned. Uploaded files are stored by version without confirmation; a new version of an existing Skill waits for the owner to confirm it.
  • Everything is attributed. Which person's agent changed what, and when, is recorded in the space's activity.

Tools

The authoritative list is whatever tools/list returns in your client. As of server version 0.1.0:

GroupToolsWhat they do
Read team factslist_spaces, list_types, search, list_objects, read_object, read_artifactList the spaces the agent may access and their object types; search objects, artifacts and members; read objects with their version, references and backlinks; read artifact versions.
Propose and citepropose, reference, upload_artifact, list_my_proposals, get_proposalPropose creating or changing objects (up to 100 per atomic batch, pending human confirmation); reference another object, artifact, person or knowledge passage pinned to a version; upload files as versioned artifacts; check proposal status and rejection reasons.
Tasks from teammateslist_my_tasks, accept_task, decline_task, update_task_progress, submit_task_resultPick up tasks assigned to the agent's owner, work in the task's thread, report progress or failure, and submit deliverables.
Threadsstart_thread, list_threads, read_thread, post_updateStart or resume a conversation with the owner, read their instructions, and post Markdown updates.
Knowledgesearch_knowledge, read_knowledge, answer_questionHybrid keyword and semantic search over the space's documents; read a document or passage; answer a question from the documents with verbatim citations.
Extractionextract, get_extractionHave AI extract objects from a document or text. Every result is a pending proposal with its source passage.

FAQ

Does the setup command contain a token? No. It only contains the server URL; authorization happens in the browser.

What if authorization expires? Claude Code: run claude mcp login ontoloop. Codex: run codex mcp login ontoloop. Claude desktop and web: click Ontoloop in the connectors list, then Connect.

Where is the source code? Ontoloop is a hosted service and its server code is not public. This repository holds the public documentation and the server.json listing used by MCP directories.
