Perplexity

Stream OTLP logs from your terminal session

The `ingest_otlp_logs` tool routes structured JSON logs containing your `highlight.project_id` from your terminal directly to Highlight. Claude Code invokes this tool during CLI sessions to log system events without opening a browser. You can pipe server outputs directly to the agent, which handles the formatting and uploads the payload. This keeps your deployment logs tied to actual user sessions automatically.

Publish trace data using this CLI MCP Server

The `ingest_otlp_traces` tool pushes OpenTelemetry JSON spans to Highlight to map terminal debug sessions to user replay timelines. Claude Code uses this tool to check backend performance issues directly from your SSH session. The command-line agent analyzes the trace hierarchy, flags slow spans, and suggests configuration adjustments. You get deep performance insights without leaving your command line.

Pipe raw logs to Highlight

The `ingest_raw_log` tool wraps unstructured terminal outputs into Highlight-compatible log envelopes for quick session linking. Claude Code calls this tool to capture stdout and stderr from failing cron jobs or CI/CD pipelines. This tool turns raw terminal noise into actionable telemetry. The agent sends the raw string, links it to your project, and prints the session replay link directly in your terminal.

Common questions about Highlight (Session Replay & UX) MCP in Claude Code

Run the command `claude mcp add --transport http highlight-mcp -- ` in your terminal. Use `claude mcp list` to verify the connection.

Yes, Claude Code runs headless inside Docker or GitHub Actions and calls the ingest tools programmatically. This lets you stream pipeline failures directly to your Highlight dashboard.

It allows SREs to query raw logs and traces directly from the terminal. The agent correlates these events with user sessions, speeding up root-cause analysis during live outages.

The server supports stdio, HTTP, and SSE transports. Vinkius manages these connections securely in a V8 sandbox, allowing Claude Code to communicate with the tools reliably.

Telemetry payloads, including raw log strings and OTLP spans, are processed inside an ephemeral sandbox. No data is stored locally in the environment, and transport is encrypted using your secure Vinkius token.
