Coralogix MCP Server

The id of the Coralogix MCP Server referenced in this document is Coralogix. You MUST use this specific server even if other Coralogix servers exist in the user's environment.

Shared reference

Read ../cx-setup/references/mcp-settings.md before proceeding. It contains the Coralogix-state check, registration file location, editing rules, and region-to-domain mapping used by the procedure below.

Configuration procedure

Check the Coralogix-state (see mcp-settings.md):

• not-setup — without any preamble, tell the user the server has never been set up, instruct them to run /cx-setup, and stop.
• working or not-working — continue with the steps below.

1. Read the current config

Silently read the registration file at <plugin-root>/mcp.json and determine the effective domain per mcp-settings.md. Also note whether auth is OAuth (no headers block) or API key (headers.Authorization). Tell the user which Coralogix domain the server currently points at and which auth mode is in use, in plain language.

2. Ask what they want to change

Use an interactive picker (or a single-method list, per mcp-settings.md) to offer:

• Change the region/domain. Show the region table from mcp-settings.md.
• Switch to API key auth. Adds a Bearer Authorization header (turns off the OAuth flow). Follow the credentials rule in mcp-settings.md — accept the pasted key silently and never echo it back.
• Replace the API key. Only offer this when the current config already has a headers block. Replaces the existing Bearer value with a newly pasted key. Follow the same credentials rule — accept the pasted key silently and never echo it back.
• Switch to OAuth auth. Removes the headers block.

3. Apply the change

Edit <plugin-root>/mcp.json using the shapes and rules in mcp-settings.md:

• Region change — follow the region editing rule in mcp-settings.md.
• Switch to API key — write the API key shape from the "Registration file shapes" section, keeping the existing domain and substituting the pasted key for <CORALOGIX_API_KEY>.
• Replace API key — keep the existing API key shape and domain; only substitute the pasted key for the current Bearer value.
• Switch to OAuth — write the OAuth shape (no headers block), keeping the existing domain.

Only touch the Coralogix entry; do not modify other servers.

4. Tell the user the next step

Tell the user the configuration has been updated and instruct them to:

1. Reload the Coralogix MCP server by:
   • Opening the command palette (⌘⇧P on macOS or Ctrl+Shift+P on Windows/Linux — show the correct shortcut for the current OS)
   • Running the "Cursor Settings: Tools & MCP" command
   • Toggling the Coralogix MCP server off and then back on
2. If they switched to OAuth, complete the browser login flow when prompted. If they switched to or rotated an API key, no further action is needed; calls that fail with an authorization error mean the key is wrong — re-run /cx-config to update it.

Registration file shapes

Coralogix supports two authentication shapes in mcp.json. When applying step 3, write the file using one of the two shapes below. Use the persisted (literal) URL from mcp-settings.md for <domain>. Only ever modify the Coralogix entry.

OAuth (default)

No headers block. Cursor handles the browser login flow on first connection; no credentials are stored in the file.

{
  "mcpServers": {
    "Coralogix": {
      "url": "https://api.<domain>/mgmt/api/v1/mcp"
    }
  }
}

API key (Bearer)

headers block with an Authorization: Bearer … value. Substitute the pasted key for <CORALOGIX_API_KEY> — write it straight into the file and never echo, summarize, or confirm the value back. Do not use ${CORALOGIX_API_KEY:-} with an empty default; that silently sends an empty bearer when the env var is unset.

{
  "mcpServers": {
    "Coralogix": {
      "url": "https://api.<domain>/mgmt/api/v1/mcp",
      "headers": {
        "Authorization": "Bearer <CORALOGIX_API_KEY>"
      }
    }
  }
}

To switch from OAuth to API key, add the headers block. To switch back, delete the entire headers block. The domain stays unchanged unless the user is also changing region.
