Smithery

Connect through Smithery using the published server entry onehorizon/onehorizon. If you are choosing between MCP setup paths, start with MCP.

Smithery can manage the MCP server entry from the published listing.

Prerequisites

• An account with access to at least one workspace (sign up at onehorizon.ai/app/auth/signup).
• A Smithery account.
• Node.js 20+ (required by the Smithery CLI).
• The Smithery CLI, either installed globally with npm install -g @smithery/cli@latest or run with npx -y @smithery/cli@latest ... for each command.

Quick start with Smithery CLI

# 1) Authenticate with Smitherynpx -y @smithery/cli@latest auth login
# 2) Connect this server with an explicit connection IDnpx -y @smithery/cli@latest mcp add onehorizon/onehorizon --id onehorizon
# 3) If output says auth_required, open setupUrlopen "https://api.smithery.ai/connect/onehorizon/onehorizon/setup"
# 4) Browse tools with the connection IDnpx -y @smithery/cli@latest tool list onehorizon
# 5) Call a toolnpx -y @smithery/cli@latest tool call onehorizon list-taxonomy '{}'
# 6) Check connected MCP entries and statusesnpx -y @smithery/cli@latest mcp list

If you installed Smithery globally, you can replace npx -y @smithery/cli@latest with smithery.

Connect from the Smithery UI

1. Open the Smithery listing.
2. Use Smithery's connect flow.
3. Smithery runs an npx command locally to start a STDIO bridge to the remote Smithery endpoint.

Direct MCP endpoint

After mcp add, Smithery CLI currently reports the MCP URL as:

https://server.smithery.ai/onehorizon/onehorizon

If the connection status is auth_required, Smithery also returns a setupUrl. Open that URL in your browser and complete authorization before calling tools.

Use npx -y @smithery/cli@latest mcp list to confirm the connection is no longer in auth_required. The OAuth model is the same user-granted access described in OAuth Apps.

Available tools

Tool groups include initiatives, bugs and feature requests, todos, recaps, team lookups, taxonomy, and comments. Fetch the current list with:
