Composio

Managed OAuth and pre-built tool connectors for 500+ apps via a single MCP server. Provides agent-native access to marketing tools that lack native MCP support.

Capabilities

Integration	Available	Notes
API	✓	REST API for managing connections and triggering actions
MCP	✓	Single MCP server exposes all connected tools
CLI	✓	npx composio for managing apps, connections, and actions
SDK	✓	TypeScript and Python SDKs

Authentication

• Type: OAuth 2.0 (per-tool, managed by Composio) or API Key
• Setup: npx @composio/mcp@latest setup to install, then authenticate each tool via Connect Link in browser
• API Key (optional): COMPOSIO_API_KEY env var for advanced/team usage

Composio handles OAuth token management, refresh, and storage for all connected tools. Individual tool auth types are listed in the Marketing Tools table below.

When to Use Composio vs. Native Tools

Composio is an alternative integration method, not a replacement. Use this decision guide:

Scenario	Use
Tool has native MCP server (GA4, Stripe, Mailchimp)	Native MCP server
Tool has CLI but no MCP (Meta Ads, LinkedIn Ads, HubSpot)	Composio for MCP access
OAuth-heavy tool with no CLI (Google Sheets, Slack, Notion)	Composio
Need deep, customized integration	Native API + CLI
Need quick read/write access across many tools	Composio
Tool not covered by Composio	Native API guide

Setup

1. Install the MCP server

npx @composio/mcp@latest setup

This adds the Composio MCP server to your Claude Code configuration.

2. Verify installation

In Claude Code, run /mcp to confirm composio appears in your MCP server list.

3. Authenticate a tool

When you first use a Composio-backed tool, you'll receive a Connect Link. Open it in your browser to complete OAuth. The connection persists across sessions.

# Example: connect HubSpot
> "Pull my top 10 HubSpot contacts"
# Agent will prompt: "Please authenticate HubSpot: [Connect Link]"
# Click link → authorize → done

4. API key (optional)

For advanced usage or team setups, set your Composio API key:

export COMPOSIO_API_KEY=your_key_here

New MCP Coverage

These tools have API guides in this repo but no native MCP server. Composio adds MCP access:

Tool	Composio Toolkit	Auth Type	Coverage Depth
HubSpot	HUBSPOT	OAuth 2.0	Deep (contacts, deals, companies, lists, email)
Salesforce	SALESFORCE	OAuth 2.0	Deep (SOQL, objects, leads, opportunities)
Meta Ads	FACEBOOKADS	OAuth 2.0	Medium (campaigns, ad sets, insights)
LinkedIn Ads	LINKEDIN	OAuth 2.0	Medium (campaigns, analytics, company pages)
Google Sheets	GOOGLESHEETS	OAuth 2.0	Deep (read, write, create, format)
Slack	SLACK	OAuth 2.0	Deep (messages, channels, files)
Notion	NOTION	OAuth 2.0	Deep (pages, databases, blocks)
Airtable	AIRTABLE	OAuth 2.0	Deep (records, tables, views)
ActiveCampaign	ACTIVECAMPAIGN	API Key	Medium (contacts, lists, automations)
Klaviyo	KLAVIYO	API Key	Medium (profiles, lists, campaigns)
Shopify	SHOPIFY	OAuth 2.0	Deep (products, orders, customers)
Gmail	GMAIL	OAuth 2.0	Deep (read, send, labels, search)

Alternative to Existing Tools

These tools already have native MCP or CLI in this repo. Composio provides an alternative path:

Tool	Native Integration	Composio Toolkit	When to Use Composio
Mailchimp	MCP ✓, CLI ✓	MAILCHIMP	If native MCP setup fails
Google Ads	MCP ✓, CLI ✓	GOOGLEADS	If OAuth is simpler via Composio
Stripe	MCP ✓, CLI ✓	STRIPE	Prefer native (deeper coverage)
GA4	MCP ✓, CLI ✓	GOOGLEANALYTICS	Prefer native (deeper coverage)

Common Agent Operations

List available tools

# Via Composio CLI
npx composio apps list

Check connection status

npx composio connections list

Trigger an action programmatically

POST https://backend.composio.dev/api/v1/actions/{action_id}/execute

{
  "connectedAccountId": "account_xxx",
  "input": {
    "query": "contact email = user@example.com"
  }
}

Disconnect a tool

npx composio connections remove {connection_id}

Example Workflows

Pull CRM data into a spreadsheet

> "Get my top 20 HubSpot contacts by last activity and add them to a Google Sheet"

Agent uses Composio's HUBSPOT to fetch contacts and GOOGLESHEETS to write rows.

Cross-platform ad reporting

> "Compare my Meta Ads and LinkedIn Ads spend this month"

Agent uses FACEBOOKADS and LINKEDIN toolkits to pull campaign data.

Notify team about new leads

> "Get my Salesforce leads from today and post a summary in Slack #sales"

Agent uses SALESFORCE to read leads and SLACK to post messages.

Limitations

• Coverage depth varies — some toolkits expose hundreds of actions (HubSpot, Google Sheets), others only a handful
• No customization — you can't modify Composio's action schemas or add custom endpoints
• Vendor dependency — if Composio's servers are down, all connected tools are unavailable
• Rate limits apply — Composio enforces its own rate limits on top of each tool's native limits
• OAuth tokens — managed by Composio; you don't control token refresh or storage
• Action naming — Composio action names may differ from native API terminology
