Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. 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 TryFundable account to Claude via Composio Connect, enabling it to find fintech companies raising Series A, list investors backing climate startups, search people at venture firms in Boston, 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.

3. Connect your TryFundable account

Back in Claude, ask it to connect to TryFundable or give it any TryFundable-related task.

For example, ask Claude to:

  • "Find fintech companies raising Series A"
  • "List investors backing climate startups"
  • "Search people at venture firms in Boston"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your TryFundable account is ready to use.

What is the TryFundable Claude Connector, and what's possible with it?

The TryFundable MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your TryFundable account. It provides structured and secure access to private-market company, investor, person, funding-deal, location, and industry data, so your agent can discover companies and investors, research funding rounds, find relevant people, and support fundraising prospecting on your behalf.

  • Company discovery: Have your agent find companies by attributes, recent funding rounds, and investor relationships.
  • Investor research: Direct your agent to identify investor firms by their characteristics and portfolio company investments.
  • Funding research: Let the agent search funding deals, review financing and valuation details, and examine the investors involved in a round.
  • People and profile lookup: Instruct your agent to find founders, employees, angels, lead investors, and full profiles for companies, firms, or people.
  • Market taxonomy support: Have your agent find recognized locations, industries, and categories to refine company, investor, and deal research.

Troubleshooting

1. Why does Claude not use the Composio connector for TryFundable?

The connector can show as connected, but Claude must use it in each TryFundable conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to TryFundable again.

2. Why does Claude show an MCP server error before TryFundable connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for TryFundable.

  • 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 TryFundable.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the TryFundable authorization link not work?

The Composio connector is one server. Your TryFundable account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the TryFundable connection.
  • Composio creates a fresh TryFundable authorization link.
  • Open that link in your browser and finish the TryFundable sign-in.

4. Why do TryFundable actions fail after they worked before?

The TryFundable connection can expire or lose permission.

  • Ask Claude to inspect the TryFundable connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the TryFundable account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in TryFundable.
  • If the action still fails with a permission error, check that the connected account has that permission in TryFundable itself.

5. How do I switch to a different TryFundable account?

Claude can manage the TryFundable connection for you.

  • Ask Claude to disconnect or delete the current TryFundable account.
  • Ask Claude to connect TryFundable again.
  • Open the new Composio authorization link for TryFundable.
  • Sign in with the other TryFundable account in the browser.
  • After the account connects, ask Claude to retry the TryFundable task.

6. Why is my TryFundable connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your TryFundable connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If TryFundable 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 TryFundable.

FAQ

Frequently asked questions

With a standalone TryFundable MCP server, the agents and LLMs can only access a fixed set of TryFundable tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from TryFundable and many other apps based on the task at hand, all through a single MCP endpoint.

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 TryFundable tools.

Yes, absolutely. You can configure which TryFundable 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.

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 TryFundable data and credentials are handled as safely as possible.
