CoreSpeed gives an agent one MCP server,
https://api.corespeed.io/mcp, that carries the tools of every app your
organization has connected (Notion, Slack, GitHub, X, Linear, and more),
long-term memory shared across agents, a Drive every tool reads and writes,
media generation and understanding, live web search, and public social data,
all billed to one wallet with spend caps and an audit trail.
This repository holds the CoreSpeed plugin for Claude Code, Codex and Cursor,
and the agent skills it bundles. The cs command-line tool is published to npm as
@corespeed/cs.
claude plugin marketplace add corespeed-io/cs
claude plugin install corespeed@corespeedInside Claude Code the same is /plugin marketplace add corespeed-io/cs, then
/plugin install corespeed@corespeed. Start a new session, run /mcp, pick
the CoreSpeed server, and authenticate in the browser.
codex plugin marketplace add corespeed-io/cs
codex plugin add corespeed@corespeedStart a new Codex task. When CoreSpeed shows Authentication required, select Authenticate (or open Settings → MCP servers → CoreSpeed) and finish the sign-in in the browser. In the ChatGPT desktop app the plugin appears under the CoreSpeed marketplace once it has been added.
In Codex the plugin's server (the root .mcp.json, the one file the OpenAI
Plugins Directory accepts) is https://api.corespeed.io/mcp/plugin/chatgpt: a
fixed, small tool list — shared memory and connector discovery — that no
organization's connector count can push past Codex's catalog limit. Claude Code
gets the full https://api.corespeed.io/mcp from .mcp.claude.json, which its
manifest declares and which replaces the root entry by name. The agent
finds an app with manage__connectors_search, hands you a link to connect it,
calls a connected app's tools through the bundled cs-cli skill
(cs mcp search, cs mcp get, cs mcp call), and moves files in and out
of the organization's Drive with cs drive.
codex plugin marketplace add corespeed-io/cs
codex plugin add corespeed-cli@corespeedThis plugin registers no MCP server. Its cs-cli skill has the agent install
the cs command-line tool, sign in once in the browser, and then find and call
CoreSpeed tools from the shell (cs mcp search, cs mcp get, cs mcp call),
and move files in and out of the organization's Drive (cs drive put,
cs drive get). Pick it when Codex cannot load your organization's full tool
list, or when you want every call to go through the shell. It is the plugin
meant for the OpenAI Plugins Directory.
In Cursor, open Customize, search the Marketplace for CoreSpeed, and install it. Pick the CoreSpeed MCP server and sign in in the browser when Cursor asks. Grok Bot loads plugins from the Cursor Marketplace, so the same plugin works there.
Cursor reads the same root .mcp.json as Codex, so its server is the plugin
surface https://api.corespeed.io/mcp/plugin/chatgpt: shared memory and
connector discovery, a list no organization's connector count can grow past
what Cursor loads. A connected app's tools and the organization's Drive are
reached through the bundled cs-cli skill (cs mcp call, cs drive).
To try this repository before a Marketplace release, copy plugins/corespeed
to ~/.cursor/plugins/local/corespeed and reload the window.
npm install -g @corespeed/cs
cs logincs signs you in through the browser, mints sk-cs- API keys for CI, switches
organizations, connects apps, and calls tools from a terminal. See the
CLI docs.
| Plugin | Part | What it does |
|---|---|---|
corespeed |
MCP server | Browser sign-in (OAuth 2.1 + PKCE), never a pasted key. Claude Code: the full https://api.corespeed.io/mcp. Codex and Cursor: the plugin surface https://api.corespeed.io/mcp/plugin/chatgpt (memory, connector discovery). |
corespeed |
cs-cli skill |
Using the cs CLI: sign-in, finding and calling tools from a shell, memory, files in the Drive, API keys, organizations, connectors, remote MCP servers, credit. |
corespeed |
cs-api skill |
Calling CoreSpeed over HTTP from code and CI: credentials, tools/list and tools/call, error codes, credits. |
corespeed-cli |
cs-cli skill |
The same skill, and nothing else: no MCP server is registered. |
If you added CoreSpeed to your client by hand earlier (claude mcp add,
codex mcp add, or an entry in Cursor's mcp.json), remove that entry
before installing the plugin, so every tool is registered once.
Sign-in happens at login.corespeed.io, and the plugins' only servers are
https://api.corespeed.io/mcp and https://api.corespeed.io/mcp/plugin/chatgpt.
Anything else claiming to be CoreSpeed is not this plugin.
Copilot in VS Code, Claude.ai, ChatGPT, and any client that speaks Streamable HTTP with MCP authorization connect with the URL alone. Per-client setup is at https://corespeed.io/docs/mcp.
