Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf. This guide walks you through the easiest and most secure way to connect your FuseAI account to Claude via Composio Connect, enabling it to search prospects matching enterprise buyer profile, add prospects to outreach sequence tomorrow, analyze website intent signals for Acme, and more such actions on your behalf without compromising your account security. Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three. ## Also integrate FuseAI MCP with - [ChatGPT](https://composio.dev/toolkits/fuseai_mcp/framework/chatgpt) - [Hermes](https://composio.dev/toolkits/fuseai_mcp/framework/hermes-agent) - [Atomic Agent](https://composio.dev/toolkits/fuseai_mcp/framework/atomic-agent) ## Connect FuseAI MCP to Claude Cowork ### Connecting FuseAI to Claude Web, Desktop, and Cowork Two ways to add the Composio connector. Pick whichever you prefer. ### 1. Add with one click Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2. [Add to Claude](https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Composio&connectorUrl=https%3A%2F%2Fconnect.composio.dev%2Fmcp) ### Add manually In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top. Click Add custom connector and paste in the Composio MCP server URL: ```bash https://connect.composio.dev/mcp ``` ## What is the FuseAI MCP server, and what's possible with it? The FuseAI MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your FuseAI account. It provides structured and secure access to your prospects, campaigns, inboxes, buyer signals, analytics, and research tools, so your agent can find prospects, manage outreach campaigns, handle messages, monitor intent, and conduct research on your behalf. - Prospecting and list management: Have your agent search for people and companies, enrich contacts, save prospects to lists, and manage existing prospect lists. - Campaign and sequence management: Direct your agent to create, update, duplicate, or delete campaigns, build email and LinkedIn sequences, attach prospect lists, and generate or reorder campaign steps. - Email and LinkedIn inbox support: Let the agent read and send messages, draft replies, organize emails with tags, and approve, decline, or skip pending outreach. - Signals, website intent, and analytics: Instruct your agent to monitor lead signals, review website visitors and trends, inspect campaign or dialer performance, and surface suggested next actions for contacts. - External and relationship research: Have your agent search and scrape the web, run deep research, explore relationship history for engaged contacts and companies, or query your internal knowledge hub. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `FUSEAI_MCP_AGENTS` | Agents | The Agents / Signals feature: create, list, activate, and pause signal monitors — recurring lead/intent watchers (e.g. companies hiring SDRs, funding announcements, people engaging with a LinkedIn post, job postings). Hand off the user's full request here for anything about signal monitors or 'agents'. | | `FUSEAI_MCP_ANALYTICS` | 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. Use for 'how is X performing / trending / up or down' questions. NOT the raw call log (that is power_dialer), and NOT for building or editing campaigns (that is campaigns). | | `FUSEAI_MCP_ASK_FUSE_BRAIN` | 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. Best tool for questions about existing relationships: history, needs, objections, commitments, deal state ('what does Dana care about?', 'which contacts mentioned budget?', 'where did the Acme deal stall?', 'who is waiting on us?'). Answers cite the contacts/companies used. Not for cold prospects: no file exists until a contact engages. | | `FUSEAI_MCP_AUTOMATIONS` | 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, ...). Route here for anything recurring — 'daily', 'every time', 'whenever', 'monitor' — or any if-this-then-that request ('automate X when Y', 'when a Typeform response arrives...', 'before each calendar meeting...'), for connecting an app an automation needs, for 'I connected , continue', and for inspecting, editing, pausing, resuming, deleting, or asking about the runs of an existing automation / rule. Pass the user's full request (verbatim) as `request`. | | `FUSEAI_MCP_CAMPAIGNS` | 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. NEW campaigns built here stay DRAFTS until the user asks to launch; an existing active campaign keeps running. (For cross-feature dashboards — dialer/prospecting/team analytics — use analytics instead.) | | `FUSEAI_MCP_DEEP_RESEARCH_START` | 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. Runs bill credits. ONLY call this when the user EXPLICITLY asks for "deep research", or confirms they want Deep Research after you offered it. For a general research/find-X request that does not say deep, do NOT call this — use the quick `research` tool, or ask the user whether they want quick research (immediate answer) or Deep Research (background, 5-20 minutes, report + prospect list) and wait for their choice. Returns immediately with a runId; it can NEVER wait for or preview results in the same call. After starting, call deep_research_status with the runId to check progress (suggest the user checks back in a few minutes). Pass the user's full request as `query`, an optional short `listName` when a list is expected, and `effort` if specified. | | `FUSEAI_MCP_DEEP_RESEARCH_STATUS` | Deep research status | Checks a Fuse Deep Research run started with deep_research_start. Returns the run status (queued/planning/running/generating_csv/uploading/completed/failed/cancelled) and, once completed, the full markdown research report plus the id of any produced prospect list. Use it whenever the user asks whether their research is done or wants the results. | | `FUSEAI_MCP_INBOX` | 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). Pass a clear, self-contained natural-language request. | | `FUSEAI_MCP_INTEGRATIONS` | 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. Pass the full task as `request`. | | `FUSEAI_MCP_POWER_DIALER` | Power dialer | Power Dialer — call history (READ-ONLY). Use for questions about the user's recent calls / call history. Cannot place or manage live calls. | | `FUSEAI_MCP_PROSPECT_LISTS` | 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. This is where you FIND the listId of a cohort (e.g. the people who visited the website) so a campaign can target it. NOT for finding brand-new prospects on the internet or the prospect database (that is prospect_search). | | `FUSEAI_MCP_PROSPECT_SEARCH` | Prospect search | Find people and companies, generate prospect/company search filters from a natural-language description, enrich contacts, and save prospects to lists. Use for anything in the Prospect Search area. | | `FUSEAI_MCP_RESEARCH` | 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. NOT for searching FuseAI's own prospect database — that's prospect_search. Examples: 'find recent funding news about Acme Corp', 'build me a list of AI infra startups in SF from the internet'. | | `FUSEAI_MCP_SETTINGS` | 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. Also the door for API keys and billing/subscription questions (it can READ the current credit balance; everything else billing it explains is app-only). NOT for CRM connection/sync/owner-mapping. Pass the full settings task as `request`. | | `FUSEAI_MCP_SMART_ACTIONS` | 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. Use it to answer 'what should I do next', to act on website-visitor or signal items one contact at a time (inspect -> enrich -> send), and to triage/execute the feed. Examples: 'what should I do next?', 'send the top suggested action', 'work through my website-visitor actions'. | | `FUSEAI_MCP_WEBSITE_INTENT` | 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). NOT for acting on visitors — to turn website visitors into a list, reach them, or add them to a campaign, use prospect_lists (the 'All Website Visitors' list) + campaigns. Examples: 'which companies visited my site this month?', 'show my visitor trend', 'is my tracking tag live on acme.io?'. | ## Supported Triggers None listed. ## Troubleshooting ### 1. Why does Claude not use the Composio connector for FuseAI? The connector can show as connected, but Claude must use it in each FuseAI conversation. - Click + at the lower left of the chat, or type /. - Hover Connectors. - Turn on Composio. - Ask Claude to connect to FuseAI again. ### 2. Why does Claude show an MCP server error before FuseAI connects? Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for FuseAI. - Check that the connector URL is https://connect.composio.dev/mcp. - Connectors run from Anthropic's cloud, so your device network is usually not the problem. - Add the connector again from Customize > Connectors, then ask Claude to connect FuseAI. - If it fails again, send the error and the ofid_ reference id to support@composio.dev. ### 3. Why does the FuseAI authorization link not work? The Composio connector is one server. Your FuseAI account connects separately when Claude asks for it. - If the browser does not open, or the link expires, ask Claude to retry the FuseAI connection. - Composio creates a fresh FuseAI authorization link. - Open that link in your browser and finish the FuseAI sign-in. ### 4. Why do FuseAI actions fail after they worked before? The FuseAI connection can expire or lose permission. - Ask Claude to inspect the FuseAI connection. - If the connection is unhealthy, disconnect it when Claude prompts you. - Reconnect the FuseAI account and retry the action. - If Claude shows a permission prompt, approve it before Claude changes data in FuseAI. - If the action still fails with a permission error, check that the connected account has that permission in FuseAI itself. ### 5. How do I switch to a different FuseAI account? Claude can manage the FuseAI connection for you. - Ask Claude to disconnect or delete the current FuseAI account. - Ask Claude to connect FuseAI again. - Open the new Composio authorization link for FuseAI. - Sign in with the other FuseAI account in the browser. - After the account connects, ask Claude to retry the FuseAI task. ### 6. Why is my FuseAI connection missing in Claude Desktop or on a Team plan? The connector belongs to your Claude account, so your FuseAI connection works in Claude Web, Desktop, and Cowork. - In Claude Desktop, open Customize > Connectors. - Next to Composio, click ⋮ and click Clear cache. - If FuseAI tools still do not appear, click ⋮, disconnect, remove the connector, and add it again. - On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect FuseAI. ## Creating MCP Server - Stand-alone vs Composio SDK The FuseAI MCP server connects Claude Web, Desktop, and Cowork to your FuseAI account through Composio. Once connected, Claude can use the available FuseAI tools and triggers to complete tasks on your behalf. ## Complete Code None listed. ## How to build FuseAI MCP Agent with another framework - [ChatGPT](https://composio.dev/toolkits/fuseai_mcp/framework/chatgpt) - [Hermes](https://composio.dev/toolkits/fuseai_mcp/framework/hermes-agent) - [Atomic Agent](https://composio.dev/toolkits/fuseai_mcp/framework/atomic-agent) ## Related Toolkits - [HubSpot](https://composio.dev/toolkits/hubspot) - HubSpot is an all-in-one marketing, sales, and customer service platform.

With a standalone FuseAI MCP server, the agents and LLMs can only access a fixed set of FuseAI tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from FuseAI and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Claude Cowork? Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right FuseAI tools. ### Can I manage the permissions and scopes for FuseAI while using Tool Router? Yes, absolutely. You can configure which FuseAI scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your FuseAI data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
