​
What it is

TierZero exposes a remote Model Context Protocol (MCP) server. AI coding assistants — Claude Code, Cursor, and any other MCP-compliant client — can call it directly to query your production context while you work.
  • Endpoint: https://api.tierzero.ai/mcp/
  • Transport: Streamable HTTP
  • Auth: OAuth 2.1 (recommended) or Personal Access Token

​
What it does

The server exposes two tools.

​
tierzero_ask

Runs a TierZero investigation against your connected production systems and returns evidence-backed findings. It can:
  • Query logs, metrics, traces, and spans from connected integrations such as Datadog, New Relic, CloudWatch, Grafana Cloud, and Sentry
  • Inspect GitHub repositories, CI/CD systems such as BuildKite and GitHub Actions, and workflow orchestration in Temporal
  • Retrieve documentation and runbooks from connected knowledge sources such as Confluence, Notion, and Slack
  • Correlate findings across telemetry, code, workflows, and documentation
Claude Code automatically loading the TierZero skill and running a TierZero production context query in the background
tierzero_ask invokes the TierZero agent, which may take several minutes for non-trivial queries. Clients that support MCP progress notifications will display progress updates during execution.

​
tierzero_fetch_context

Loads an existing TierZero chat, investigation, or artifact into your IDE so you can act on it without starting a new investigation. Claude Code fetching existing TierZero chat context and using it to answer a follow-up question Arguments:
  • url: A TierZero chat URL (https://app.tierzero.ai/chat/c/<GlobalID>), investigation URL (https://app.tierzero.ai/investigations/<GlobalID>), or raw GlobalID
  • include_sources: Optional boolean. Set to true to include source metadata in the response

​
Choosing a client

Pick the setup guide that matches your client:

Claude Code

Plugin install + OAuth. Recommended for Claude Code users.

Cursor

Cursor marketplace install + OAuth.

Other MCP clients

Any HTTP MCP client. OAuth 2.1 or PAT.

​
Troubleshooting

​
Authentication didn’t pop up

Run /mcp in Claude Code, or open the MCP panel in Cursor settings, and click Authenticate on the tierzero server.

​
Token expired or revoked

Reconnect from the same place: /mcp in Claude Code, or the Tools & MCP panel in Cursor. The client will start a fresh OAuth flow. If you’re using a PAT, generate a new one at auth.tierzero.ai/account/api_keys/ and update your client config.

​
Connection issues

Confirm https://api.tierzero.ai/mcp/ is reachable from your network and that your client supports HTTP transport. Older MCP clients that only support stdio transport are not compatible with the remote server.
