TOOLS

Supported Tools

Every FuseAI MCP action and event your agent gets out of the box.

Agents

The Agents / Signals feature: create, list, activate, and pause signal monitors — recurring lead/intent watchers (e.

Analytics

Read-only performance dashboards & metrics: campaign metrics and trends (email / LinkedIn / dialer, with up-or-down deltas), dialer call analytics, prospecting/enrichment volumes, and team performance.

Ask fuse brain

Ask the Fuse Brain — living relationship files for ENGAGED contacts/companies, built from the team's real emails, LinkedIn messages, calls and meetings.

Automations

Create and manage AUTOMATIONS — scheduled or event-triggered multi-step rules (website/news monitors with Slack digests, follow-up drafts, auto-enrolment into campaigns, CRM saves, AI steps, and rules that listen to or act in the user's connected apps: Google Calendar, Google Sheets, Notion, Typeform, Zendesk, Airtable, Asana, Linear, .

Campaigns

Outreach campaigns and their email/LinkedIn/dialer SEQUENCES, end to end: list/create/update/duplicate/delete campaigns; build, generate, edit, reorder, test and preview sequence steps; ATTACH LISTS to a campaign (this is how you set up reaching a list of people, including system lists like All Website Visitors — attaching to an ALREADY-ACTIVE campaign enrolls its contacts in the background, while a draft campaign enrolls at launch); manage leads (pause/resume, activity); templates; and per-campaign performance metrics + trends.

Deep research start

Starts an asynchronous Fuse Deep Research run: over several minutes it researches the request across the web in the background and produces a markdown report, plus — when the request is to find people or companies — a new Fuse prospect list.

Deep research status

Checks a Fuse Deep Research run started with deep_research_start.

Inbox

Use for anything in the user's inbox / messaging: reading, sending, flagging (read/archive/spam/delete), and tagging emails; AI-drafting email or LinkedIn replies; approving/declining/skipping pending auto-replies; and LinkedIn messaging (chats, messages, connections, invitations).

Integrations

CRM & integrations: connection status, CRM Fields/sync settings, owner mapping, pulling/pushing contacts & companies to the connected CRM (HubSpot/Salesforce/Zoho/Pipedrive/Attio), custom contact properties, and Slack notifications.

Power dialer

Power Dialer — call history (READ-ONLY).

Prospect lists

Manage the user's prospect lists: list lists (including the system/auto lists — All Website Visitors, All Saved Contacts, All Leads, All Enriched Contacts), view/search a list's rows, create/append/clean lists, smart columns, and resolve a list's real id.

Prospect search

Find people and companies, generate prospect/company search filters from a natural-language description, enrich contacts, and save prospects to lists.

Research

EXTERNAL / internet research and web tasks: search & scrape the web (Firecrawl), Google Maps & Google Jobs lookups, building a prospect list from the web (EXA websets), internal knowledge-hub semantic search, and FuseAI how-to / navigation help.

Settings

Account & workspace settings: company profile (name/website), enrichment preferences, team members & invitations, Knowledge Hub profiles, writing styles, ICPs (Ideal Customer Profiles), campaign visibility, a thin lifecycle view of existing Rules Engine automations (list/pause/resume/delete only — it does NOT create or edit automations), Deep Research provider keys (BYOK), and MANAGING the connected sending accounts — email accounts (settings/sharing/disconnect/SMTP connect/warmup start-pause), LinkedIn accounts, dialer phone numbers, and purchased sending domains & mailboxes.

Smart actions

The Smart Actions feed — the home list of suggested next actions per contact, aggregated from website visits, signal-monitor matches, campaign replies, and ICP matches.

Website intent

Use for Website Intent READ-ONLY reports + tracking config: who (companies/people/industries) is visiting the website, visitor analytics/trends, and the tracking setup (allowed domains, tag script, de-anonymization credits).

FAQ

Frequently asked questions

Yes, FuseAI MCP requires you to configure your own Dcr Oauth credentials. Once set up, Composio handles secure credential storage and management for you.

Yes! Composio's Tool Router enables agents to use multiple toolkits. Learn more.

Yes. Composio is SOC 2 Type II compliant and is built to keep your FuseAI connection and credentials secure. OAuth tokens and API keys are encrypted, and sensitive customer data is protected at rest and in transit.

Composio also undergoes independent security testing and continuously monitors its systems for security threats. You can review the latest reports and policies in the Composio Trust Center.

Composio maintains and updates all toolkit integrations automatically, so your agents always work with the latest API versions.

When you connect a FuseAI account through Composio, every action runs under that account, so anything the agent creates, sends, or changes shows up in FuseAI as done by you. Keep an approval step in your prompt for actions with side effects, such as sending or deleting, and have the agent draft first.

Whatever the credentials you connect allow inside FuseAI. If FuseAI lets you scope a key to specific permissions, create a scoped one so the agent can only do what you intend. You can revoke the key inside FuseAI at any time.

Yes. Composio supports multiple connected accounts for the same app, and that works in Claude, ChatGPT, or any other assistant you connect through Composio. Give each FuseAI connection a name such as work or personal, and the assistant uses the one you mention in the request. Each account keeps its own credentials and nothing is merged.

Composio's free Hobby plan includes 100,000 tool calls per month with no credit card, which covers most personal FuseAI use. Paid plans add higher limits and team features. Your FuseAI plan and its API limits still apply as usual.

Built-in connectors usually give one AI access to a limited set of apps. Many people use Composio because it lets their AI connect to more apps than it normally supports, or connect to multiple accounts for the same app (e.g. connect Claude to multiple FuseAI accounts).

With Composio, you connect FuseAI once and then use it across different AI assistants without setting it up separately in each one. Connect your apps to Composio once, then connect Composio to whichever AI you use, whether that's Claude, ChatGPT, Hermes, or your own custom assistant.
