## 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 Finlight account to Claude via Composio Connect, enabling it to summarize market-moving Finlight articles today, list recent Finlight articles about Apple, retrieve Finlight article by link and summarize, 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.

## What is the Finlight MCP server, and what's possible with it?

The Finlight MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Finlight account. It provides structured and secure access so your agent can perform Finlight operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `FINLIGHT_GET_ARTICLE_BY_LINK` | Get Article by Link | Retrieve one Finlight-indexed article by its original URL. Optional full content and company entities are plan-gated and may be silently absent even when the request succeeds. |
| `FINLIGHT_LIST_SOURCES` | List Sources | List all news source domains visible to the connected Finlight account, including default-source status, origin country, and supported languages. |
| `FINLIGHT_SEARCH_ARTICLES` | Search Articles | Search Finlight's indexed financial news using text, market, source, geography, category, language, and date filters. Returns one page at a time. Availability, recency, content, and entity enrichment depend on the connected plan and may be silently omitted. |

## Supported Triggers

## Troubleshooting

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

The connector can show as connected, but Claude must use it in each Finlight conversation.
- Click + at the lower left of the chat, or type /.
- Hover Connectors.
- Turn on Composio.
- Ask Claude to connect to Finlight again.

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

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Finlight.
- 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 Finlight.
- If it fails again, send the error and the ofid_ reference id to support@composio.dev.

### 3. Why does the Finlight authorization link not work?

The Composio connector is one server. Your Finlight account connects separately when Claude asks for it.
- If the browser does not open, or the link expires, ask Claude to retry the Finlight connection.
- Composio creates a fresh Finlight authorization link.
- Open that link in your browser and finish the Finlight sign-in.

### 4. Why do Finlight actions fail after they worked before?

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

### 5. How do I switch to a different Finlight account?

Claude can manage the Finlight connection for you.
- Ask Claude to disconnect or delete the current Finlight account.
- Ask Claude to connect Finlight again.
- Open the new Composio authorization link for Finlight.
- Sign in with the other Finlight account in the browser.
- After the account connects, ask Claude to retry the Finlight task.

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

The connector belongs to your Claude account, so your Finlight connection works in Claude Web, Desktop, and Cowork.
- In Claude Desktop, open Customize > Connectors.
- Next to Composio, click ⋮ and click Clear cache.
- If Finlight 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 Finlight.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Finlight MCP?

With a standalone Finlight MCP server, the agents and LLMs can only access a fixed set of Finlight tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Finlight 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 Finlight tools.

### Can I manage the permissions and scopes for Finlight while using Tool Router?

Yes, absolutely. You can configure which Finlight 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 Finlight data and credentials are handled as safely as possible.
