• A Smithery account.
• Node.js 20+ (required by the Smithery CLI).
• Smithery CLI access:
  • Global install (optional): npm install -g @smithery/cli@latest
  • No install path: use npx -y @smithery/cli@latest ... for each command.

# 2) Connect this server (explicit connection ID)npx -y @smithery/cli@latest mcp add onehorizon/onehorizon --id onehorizon

Connect from the Smithery UI

1. Open One Horizon on Smithery.
2. Use Smithery's one-click connect flow.
3. Smithery's own quickstart docs note this flow runs an npx command locally to start a local STDIO bridge to the remote Smithery endpoint.

Direct MCP Endpoint

After mcp add, Smithery CLI currently reports the One Horizon 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.

Available Tools

Smithery currently reports:

• 22 tools
• 6 prompts

Major tool groups include initiatives, bugs/feature requests, TODOs, recaps, team lookups, taxonomy, and task comments.

Use this command anytime you want the live list:

npx -y @smithery/cli@latest tool list onehorizon

Troubleshooting

Smithery Command Not Found

Either install the CLI globally, or continue using npx for every command.

npm install -g @smithery/cli@latest

No API Key Found

Authenticate first, then retry the connection command.

npx -y @smithery/cli@latest auth login

Auth Required After mcp add

Open the setupUrl shown in terminal, complete authorization, then retry tool commands.

open "https://api.smithery.ai/connect/onehorizon/onehorizon/setup"npx -y @smithery/cli@latest tool list onehorizon

Connection Not Found

tool list and tool call use the connection ID, not the qualified server name.

npx -y @smithery/cli@latest mcp listnpx -y @smithery/cli@latest tool list onehorizon

Invalid Token Errors

Re-authenticate and reconnect.

npx -y @smithery/cli@latest auth loginnpx -y @smithery/cli@latest mcp add onehorizon/onehorizon --id onehorizon

npx Command Fails Immediately

Verify Node.js 20+ is installed (required by Smithery CLI docs).

Tools Missing After Connect

Confirm you connected onehorizon/onehorizon specifically and that the connection is not in auth_required.
