Connect Apps

Connect Claude to external apps like Gmail, Slack, GitHub. Use this skill when the user wants to send emails, create issues, post messages, or take actions i...

Security Scan

The skill's instructions are coherent with its stated purpose (it installs a third‑party router to act on many apps), but the registry metadata omits the credential and authorization requirements and the runtime delegates broad access to an external service — a notable mismatch users should understand before installing.

Purpose & Capability

The name/description (connect to Gmail, Slack, GitHub, etc.) matches the runtime instructions: install a composio Tool Router plugin and authorize via OAuth. However, the Skill metadata lists no primary credential or required env vars while the instructions explicitly require an API key and OAuth authorizations; this metadata omission reduces transparency.

Instruction Scope

SKILL.md only tells the agent (and user) to run platform-specific plugin commands and to complete OAuth flows; it does not instruct the agent to read local files, environment variables, or other system state. Actions are delegated to the composio service which then performs app-specific calls.

Install Mechanism

This is an instruction-only skill (no install spec, no code shipped). The install directive is a platform plugin command (/plugin install composio-toolrouter), so nothing in the skill writes arbitrary binaries to disk from unknown URLs. Risk is moved to the external plugin/service, not to this skill bundle.

Credentials

The registry declares no required env vars or primary credential, but SKILL.md instructs the user to provide a 'free API key' from platform.composio.dev and to complete OAuth authorizations that grant access to many apps. That broad access is expected for this capability but the discrepancy between metadata and runtime reduces transparency and could surprise users. Users should verify what tokens/scopes the external service will receive.

Persistence & Privilege

always is false and there is no install spec that modifies agent/system configs. The plugin approach implies the external service will hold OAuth tokens, but this skill itself does not request permanent agent-wide privileges in the registry.

What to consider before installing

This skill delegates actions to a third‑party service (Composio Tool Router). Before installing: (1) Verify platform.composio.dev and the composio plugin are trustworthy (homepage/source code, company reputation). (2) Expect to provide an API key and complete OAuth flows — doing so grants the external service the ability to act on your accounts (send email, post to Slack, create GitHub issues). Review and limit OAuth scopes where possible, and prefer authorizing only the accounts you intend to use. (3) Note the skill metadata does not declare the API key/OAuth requirement — treat that as a transparency gap. (4) If you need stronger assurance, request the plugin's source or audit the composio service's privacy/security docs and confirm how to revoke tokens. If you are unsure about granting broad access, do not install.

Connect Claude to 1000+ apps. Actually send emails, create issues, post messages - not just generate text about it.

Quick Start

Step 1: Install the Plugin

/plugin install composio-toolrouter

Step 2: Run Setup

/composio-toolrouter:setup

This will:

• Ask for your free API key (get one at platform.composio.dev)
• Configure Claude's connection to 1000+ apps
• Take about 60 seconds

Step 3: Try It!

After setup, restart Claude Code and try:

Send me a test email at [e-mail]

If it works, you're connected!

What You Can Do

Ask Claude to...	What happens
"Send email to [e-mail] about the launch"	Actually sends the email
"Create GitHub issue: fix login bug"	Creates the issue
"Post to Slack #general: deploy complete"	Posts the message
"Add meeting notes to Notion"	Adds to Notion

Supported Apps

Email: Gmail, Outlook, SendGrid Chat: Slack, Discord, Teams, Telegram Dev: GitHub, GitLab, Jira, Linear Docs: Notion, Google Docs, Confluence Data: Sheets, Airtable, PostgreSQL And 1000+ more...

How It Works

1. You ask Claude to do something
2. Composio Tool Router finds the right tool
3. First time? You'll authorize via OAuth (one-time)
4. Action executes and returns result

Troubleshooting

• "Plugin not found" → Make sure you ran /plugin install composio-toolrouter
• "Need to authorize" → Click the OAuth link Claude provides, then say "done"
• Action failed → Check you have permissions in the target app
