CoreSpeed

CoreSpeed for coding agents

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 Code

claude plugin marketplace add corespeed-io/cs
claude plugin install corespeed@corespeed

Inside 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

codex plugin marketplace add corespeed-io/cs
codex plugin add corespeed@corespeed

Start 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.

Codex installs the self-contained plugins/corespeed-directory/ package. It uses https://api.corespeed.io/mcp/plugin/chatgpt: nine memory operations, current identity and completion of memory write approvals. Its corespeed-memory skill guides recall, saving, correction, memory links and deletion. New memories are private unless you ask to share them. This is the package prepared for OpenAI Directory review; it contains no general CLI or HTTP API skill and does not operate connected apps or files. It requires the narrowed memory contract to be deployed before installation or submission. It keeps the same MCP URL already configured for the plugin; there is no server-address migration.

Claude Code keeps the full server and the CLI/API skills in plugins/corespeed/. Cursor uses that package with the same memory-only plugin endpoint, plus the broader CLI/API skills. Codex has one manifest, in plugins/corespeed-directory/.

Codex, CLI only

codex plugin marketplace add corespeed-io/cs
codex plugin add corespeed-cli@corespeed

This 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 remains available separately from the repository marketplace. It is not part of the Directory memory package, and its availability here is not an OpenAI approval.

Cursor and Grok Bot

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 legacy package's root .mcp.json, so its server is the plugin surface https://api.corespeed.io/mcp/plugin/chatgpt: the same eleven memory, identity and approval operations as the Directory package. 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.

The cs CLI

npm install -g @corespeed/cs
cs login

cs 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.

What the plugins contain

The public Directory upload is only plugins/corespeed-directory/, with the manifest at its root under .codex-plugin/. Do not upload this entire repository or the legacy plugins/corespeed/ package. Run python3 scripts/check-directory.py before packaging. CI checks the exact file inventory so a broader skill cannot enter the upload accidentally.

Standalone CLI installation remains your choice, using npm or the separate corespeed-cli plugin above. The memory plugin neither requires nor installs it and does not use it to complete an unavailable or denied operation. CLI sign-in is separate; plugin credentials are not copied.

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.

Other clients

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.
