Introduction

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows.

This guide explains the easiest and most robust way to connect your Snowflake Basic account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.

What is Composio Connect?

Composio Connect is a consumer offering that lets anyone plug 1,000+ applications directly into their agent harness — including Hermes. It can:

  • Search and load tools from relevant toolkits on-demand, reducing context usage.
  • Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
  • Manage app authentication end-to-end with zero manual overhead.

Integrating Snowflake Basic with Hermes

Using Composio Connect CLI

1. Install the Composio CLI

Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.

bash
curl -fsSL https://composio.dev/install | bash
Hermes authenticating with Composio

2. Authenticate

Once the CLI is installed, ask Hermes to authenticate with Composio.

3. Connect to Snowflake Basic

Ask your agent to connect to Snowflake Basic, or simply request any Snowflake Basic-related task. Hermes will prompt you to authenticate and authorize access.

4. Done. You're all set with a new Snowflake Basic connection.

Using Composio Connect MCP

1. Get your MCP URL and API Key

Go to dashboard.composio.dev and copy your Connect MCP URL and API key.

What is the Snowflake Basic MCP server, and what's possible with it?

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

Supported Tools & Triggers

Tools
Describe tableRetrieves detailed information for each column (including name, data type, kind, nullability, default value, and key status) in a specified snowflake table.
Explore ColumnsRetrieves a sample of distinct values for specified columns from a snowflake table.
Run QueryExecutes the given sql query in snowflake within the specified database and schema (which must exist and be accessible), automatically setting context first.
Show databasesRetrieves a list of all databases available in the snowflake account.
Show schemasRetrieves a list of all schemas within a specified snowflake database.
Show TablesRetrieves a list of tables, including their row counts and sizes in bytes, from a specified schema within a snowflake database.

Way Forward

With Snowflake Basic connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.

From here, you can extend Hermes further:

  • Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you.
  • Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
  • Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

FAQ

What are the differences in Tool Router MCP and Snowflake Basic MCP?

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

Can I use Tool Router MCP with Hermes?

Yes, you can. Hermes 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 Snowflake Basic tools.

Can I manage the permissions and scopes for Snowflake Basic while using Tool Router?

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