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 Consensus account to Claude via Composio Connect, enabling it to find randomized trials on diabetes treatments, list citations for COVID-19 vaccine studies, summarize methodology of recent Alzheimer trials, 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 Consensus MCP with - [ChatGPT](https://composio.dev/toolkits/consensus_mcp/framework/chatgpt) - [Hermes](https://composio.dev/toolkits/consensus_mcp/framework/hermes-agent) ## Connect Consensus MCP to Claude Cowork ### Connecting Consensus 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 Consensus MCP server, and what's possible with it? The Consensus MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Consensus account. It provides structured and secure access so your agent can perform Consensus operations on your behalf. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `CONSENSUS_MCP_SEARCH` | Search | Search over 220 million peer-reviewed academic papers. Use this tool when the user asks about research, studies, evidence, scientific findings, clinical trials, medical research, or academic literature. Covers Semantic Scholar, PubMed, Scopus, and ArXiv. Returns paper titles, authors, abstracts, citation counts, journal quality scores, and direct URLs to each paper. All filters are optional — only apply them when the user explicitly asks. Example query → filter mappings: - "what does the evidence say about metformin for longevity?" → query="metformin longevity mortality", medical_mode=True, exclude_preprints=True - "recent peer-reviewed RCTs on SGLT2 inhibitors for heart failure" → query="SGLT2 inhibitors heart failure outcomes", year_min=2022, exclude_preprints=True, study_types=["rct"] - "long-term studies of statin side effects (1+ year)" → query="statin adverse effects long-term", duration_min=365, medical_mode=True - "what is dark matter?" → query="dark matter" (no filters — general question) - "coffee and cognition, excluding top-tier Q1 journals" → query="coffee cognition", sjr_min=2 | ## Supported Triggers None listed. ## Troubleshooting ### 1. Why does Claude not use the Composio connector for Consensus? The connector can show as connected, but Claude must use it in each Consensus conversation. - Click + at the lower left of the chat, or type /. - Hover Connectors. - Turn on Composio. - Ask Claude to connect to Consensus again. ### 2. Why does Claude show an MCP server error before Consensus connects? Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Consensus. - 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 Consensus. - If it fails again, send the error and the ofid_ reference id to support@composio.dev. ### 3. Why does the Consensus authorization link not work? The Composio connector is one server. Your Consensus account connects separately when Claude asks for it. - If the browser does not open, or the link expires, ask Claude to retry the Consensus connection. - Composio creates a fresh Consensus authorization link. - Open that link in your browser and finish the Consensus sign-in. ### 4. Why do Consensus actions fail after they worked before? The Consensus connection can expire or lose permission. - Ask Claude to inspect the Consensus connection. - If the connection is unhealthy, disconnect it when Claude prompts you. - Reconnect the Consensus account and retry the action. - If Claude shows a permission prompt, approve it before Claude changes data in Consensus. - If the action still fails with a permission error, check that the connected account has that permission in Consensus itself. ### 5. How do I switch to a different Consensus account? Claude can manage the Consensus connection for you. - Ask Claude to disconnect or delete the current Consensus account. - Ask Claude to connect Consensus again. - Open the new Composio authorization link for Consensus. - Sign in with the other Consensus account in the browser. - After the account connects, ask Claude to retry the Consensus task. ### 6. Why is my Consensus connection missing in Claude Desktop or on a Team plan? The connector belongs to your Claude account, so your Consensus connection works in Claude Web, Desktop, and Cowork. - In Claude Desktop, open Customize > Connectors. - Next to Composio, click ⋮ and click Clear cache. - If Consensus 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 Consensus. ## Creating MCP Server - Stand-alone vs Composio SDK The Consensus MCP server connects Claude Web, Desktop, and Cowork to your Consensus account through Composio. Once connected, Claude can use the available Consensus tools and triggers to complete tasks on your behalf. ## Complete Code None listed. ## How to build Consensus MCP Agent with another framework - [ChatGPT](https://composio.dev/toolkits/consensus_mcp/framework/chatgpt) - [Hermes](https://composio.dev/toolkits/consensus_mcp/framework/hermes-agent) ## Related Toolkits - [Canvas](https://composio.dev/toolkits/canvas) - Canvas is a learning management system for online courses, assignments, grading, and collaboration.

With a standalone Consensus MCP server, the agents and LLMs can only access a fixed set of Consensus tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Consensus 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 Consensus tools. ### Can I manage the permissions and scopes for Consensus while using Tool Router? Yes, absolutely. You can configure which Consensus 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 Consensus data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
