AI workspace — shared knowledge, skills, and tools for AI agents

VerifiedStreamable HTTPWeb executableProductivity & WorkflowKnowledge & MemoryAI & ML

Overview

AI-generated overview

Alloy is a hosted MCP endpoint that gives an AI agent a shared team workspace for reading knowledge, writing artifacts, and running workflows.

What you can do
  • Read shared organizational knowledge, docs, decisions and context before answering
  • Write durable artifacts back to Alloy such as proposals, research, summaries, specs and notes
  • Reach approved business systems through Alloy-governed upstream MCPs, APIs, files and secrets
  • Delegate work to Alloy cloud agents and continue from their outputs
  • Create AI teammates, instruction skills and executable workflows, and coordinate multi-agent handoffs
When to use it
Useful when a team wants several AI agents and people to share one source of truth for knowledge, artifacts and governed tool access, instead of configuring each integration per agent. Also suited to delegating work to cloud agents or turning repeatable work into governed workflows.
Requirements
A remote endpoint at api.alloy.cx over streamable HTTP, with a required bearer token sent in the Authorization header. The token comes from the Alloy PATs tab; the bundled plugin config reads it from the ALLOY_TOKEN environment variable, and the host must be restarted after install. An Alloy account is needed.
Before you install
The bearer token grants access to the workspace and to whatever upstream systems Alloy governs, so treat it as a secret and keep it out of shared config. The server can write artifacts, create workflows and teammates, and trigger actions in connected business systems, so changes may be visible to teammates and other agents. Access to CRM, email, calendars, databases and internal systems passes through Alloy.

Installation

In SourceWeft

  1. Open Alloy in the dashboard and add it to a workspace.
  2. Connect Authorization token credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/cx.alloy%2Falloy/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Work with Alloy

About Alloy

Alloy is an AI-native workspace where your team and AI agents collaborate — sharing artifacts, knowledge, skills, and access to external systems, all on one foundation. Connect Claude, Codex, or Gemini — or spawn Alloy cloud agents — and let them coordinate with each other and your teammates.

This plugin teaches any AI agent to use Alloy as its source of truth and gives it reusable Alloy-specific operating skills — reading shared knowledge before answering, writing durable notes and artifacts, creating workflows, running operational reviews, and spawning autonomous agents.

The shared source of truth is the work-with-alloy skill. Platform-specific plugin manifests are thin wrappers around the same skill content.

Use Cases

Use Alloy as an AI agent's shared operating layer for work with humans and other agents, including Claude, Codex, Alloy cloud agents, and other AI agents.

  • Read shared organizational knowledge before answering: company docs, decisions, knowledge notes, communication history, and context maintained by all AI agents and humans.
  • Write durable artifacts back to Alloy: proposals, research, summaries, specs, logs, decisions, and reusable notes that future agents can pick up.
  • Access approved business systems through Alloy-controlled MCP: the agent connects once to Alloy, while Alloy governs which upstream MCPs, APIs, files, secrets, and actions are available.
  • Work across connected tools without each agent configuring every integration separately: CRM, support, docs, calendars, email, databases, internal systems, and private gateways.
  • Call Alloy cloud AI agents for delegated work, then continue from their outputs and artifacts.
  • Create or configure Alloy AI teammates, instruction skills, and executable workflows so repeatable work becomes a governed organizational process.
  • Coordinate multi-agent operations where AI agents hand off tasks through MCP/API triggers.
  • Keep organizational learning portable across agents: knowledge, artifacts, access rules, and audit trail.

Layout

  • skills/work-with-alloy/ - core source-of-truth skill.
  • skills/review-alloy-operations/ - operational review skill for auditing teammates, instruction skills, workflows, MCPs, and recent activity.
  • skills/*/references/ - supporting playbooks loaded by each skill.
  • skills/*/agents/openai.yaml - Codex/OpenAI skill UI metadata.
  • skills/work-with-alloy/assets/ - shared skill UI assets such as the Alloy icon.
  • .codex-plugin/plugin.json - Codex plugin manifest.
  • .claude-plugin/plugin.json - Claude Code plugin manifest.
  • .mcp.json - Alloy hosted MCP configuration using ALLOY_TOKEN.

Shared Skill

The skills under skills/ are intended to stay host-neutral. Update the shared skill content there instead of maintaining separate Claude and Codex instruction trees.

Prerequisites

These apply to anyone installing the plugin into Claude Code or Codex.

1. ALLOY_TOKEN environment variable

The bundled .mcp.json reads the Alloy MCP bearer from ALLOY_TOKEN. Export it in the host shell before starting Claude Code or Codex:

export ALLOY_TOKEN="<your-alloy-token>"

Get a token at https://alloy.cx/docs/reference/tech-docs/hosted-mcp.

2. Host restart after install

The plugin's MCP server is loaded by the host at startup. After installing or updating the plugin, restart the host so it can load the bundled MCP config.

Codex

The Codex plugin manifest references ./skills/ and ./.mcp.json.

Set ALLOY_TOKEN in the host environment before using the bundled MCP config.

Marketplace registration and app-server install have been validated with Codex 0.125.0:

bash
codex plugin marketplace add Alloy-Systems/alloy-marketplace

Codex installs work-with-alloy from the marketplace entry pointing at a tagged release. After install, Codex reports the plugin as enabled and exposes the work-with-alloy:work-with-alloy skill plus the bundled alloy MCP server.

Claude Code

The Claude plugin manifest at .claude-plugin/plugin.json references the same ./skills/ and ./.mcp.json as the Codex side. Install flow once the Alloy marketplace is published:

/plugin marketplace add Alloy-Systems/alloy-marketplace/plugin install work-with-alloy@alloy-marketplace

Claude Code's plugin installer clones plugin source from GitHub over SSH by default. Before /plugin install, make sure one of these is true:

  • A working GitHub SSH key on this machine (test: ssh -T [email protected]).

  • A global git URL rewrite that pushes plugin clones through HTTPS:

    git config --global url."https://github.com/".insteadOf "[email protected]:"

Set ALLOY_TOKEN in the host environment before using the bundled MCP config.

After install, restart Claude Code and confirm registration:

claude mcp list   # expect plugin:work-with-alloy:alloy as connected

Versioning policy

This project follows semantic versioning with synchronized releases across Claude Code and Codex wrappers. A single version applies to the whole release: the shared skill content in skills/work-with-alloy/, both plugin.json manifests, the .mcp.json config, and this README. Both .codex-plugin/plugin.json and .claude-plugin/plugin.json always carry the same version field.

Semver semantics for this plugin

BumpWhat it meansExamples
Patch (0.1.0 → 0.1.1)Cosmetic only. Typo, wording tweak, broken link, clarification. No change in how the agent behaves.Fix a typo in SKILL.md. Update a stale URL in references/.
Minor (0.1.0 → 0.2.0)Backward-compatible addition. New rule, new Quick Reference row, new reference playbook, new optional manifest field. Prior usage still works.Add a new rule to Core rules. Add a new entry to a Quick Reference table. Add a new playbook under references/.
Major (0.x → 1.0, 1.x → 2.x)Breaking change. A canonical path, file name, required field, or required rule changes in a way that prior consumers may break.Rename Personal/<username>/.knowledge/knowledge.md to a different path. Remove a Core rule. Restructure references/ so existing links break.

Pre-1.0 (0.x) signals "still stabilizing - minor bumps may include breaking changes". The 1.0.0 line will be cut when the canonical paths and Core rules are confirmed stable.

Release flow

  1. Work happens on feature branches, merged into main via PR.
  2. When main is in a state worth releasing, bump both .codex-plugin/plugin.json and .claude-plugin/plugin.json version fields in the same commit.
  3. Cut a git tag on the merge commit: git tag vX.Y.Z && git push origin vX.Y.Z.
  4. Bump the corresponding ref field in the Alloy-Systems/alloy-marketplace repo's marketplace.json entry for work-with-alloy. Users receive the new version through /plugin update only after this marketplace bump.
  5. Untagged commits on main are visible to anyone reading the repo but are not delivered through /plugin install or /plugin update until the marketplace points at a new tag.

Cadence

Tags are cut per logical release, not on every commit. A typical trigger is a new Core rule landing, a new reference playbook being added, or a breaking restructure being completed and ready to ship. Cosmetic-only changes can accumulate in main and be released as a patch bump when convenient.
