    • Expanded README.md with detailed getting started instructions, including configuration examples for various clients like Claude Desktop, Codeium, Cursor, and Gemini CLI.
    • Added sections for quick start, installation, features, configuration, tools reference, example queries, common workflows, and troubleshooting.
  • Configuration:
    • Set default BACKEND_URL to http://localhost:16686 in BackendConfig in config.py.
  • Logging:
    • Enhanced logging in main() in server.py to include backend type and URL when starting the server.

Walkthrough

README.md undergoes rebranding and restructuring with updated project naming conventions, installation instructions, configuration examples, and backend integration details. Two minor code changes add a default BACKEND_URL value and enhance server startup logging with configuration details.

Changes

Cohort / File(s) Summary
Documentation
README.md
Comprehensive rewrite covering branding updates (OpenTelemetry-MCP-Server → OpenTelemetry MCP Server), reorganized sections (installation, quick start, configuration, usage), updated backend examples (Jaeger, Tempo, Traceloop), expanded tooling references, backend support matrix, and developer setup instructions with new CLI/JSON configuration examples.
Configuration
src/opentelemetry_mcp/config.py
BACKEND_URL environment variable now optional with default value "http://localhost:16686" instead of raising ValueError when missing.
Server Logging
src/opentelemetry_mcp/server.py
Stdio transport log message enhanced to include backend type and URL from current configuration.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

  • Code changes are minimal and localized to configuration defaults and a single log statement
  • Documentation rewrite is substantial but primarily formatting, reorganization, and example updates rather than requiring logic verification
  • No complex logic changes or architectural modifications

Poem

🐰 Behold! Our server now greets the dawn,
With README reborn and defaults drawn,
Jaeger, Tempo, and Traceloop align,
Backend whispers in logs so fine,
Optional paths where configs shine!

Several code blocks in the "Common Workflows" section lack language specifiers, which reduces syntax highlighting and readability.

While bare URLs work, markdown links provide better formatting and accessibility.

690-692: LGTM! Enhanced logging improves debuggability.

The addition of backend type and URL to the startup log message provides valuable visibility into the server configuration, making it easier to verify correct setup during initialization.

⚠️ Potential issue | 🟠 Major

Consider validating default URL matches backend type.

The default URL http://localhost:16686 is specific to Jaeger. If a user sets BACKEND_TYPE=tempo or BACKEND_TYPE=traceloop without providing BACKEND_URL, they'll get an incorrect default that will cause connection failures.

Consider either:

  1. Making the default URL conditional on backend type
  2. Adding validation to warn when non-Jaeger backends use the Jaeger default URL
  3. Documenting this behavior clearly in error messages

Example conditional approach:

backend_type = os.getenv("BACKEND_TYPE", "jaeger")
backend_url_env = os.getenv("BACKEND_URL")

if backend_url_env is None:
    # Set default based on backend type
    default_urls = {
        "jaeger": "http://localhost:16686",
        "tempo": "http://localhost:3200",
        "traceloop": "https://api.traceloop.com",
    }
    backend_url = default_urls.get(backend_type, "http://localhost:16686")
    logger.info(f"Using default URL for {backend_type}: {backend_url}")
else:
    backend_url = backend_url_env
🤖 Prompt for AI Agents
In src/opentelemetry_mcp/config.py around lines 36-37, the code always defaults
BACKEND_URL to the Jaeger URL regardless of BACKEND_TYPE, which can cause
incorrect connections for tempo/traceloop; fix by reading BACKEND_URL env first
and if unset choose a default based on BACKEND_TYPE (use a small mapping for
jaeger/tempo/traceloop and a sensible fallback), or keep the existing default
but add a validation/warning when BACKEND_TYPE is non-jaeger and BACKEND_URL is
missing; also emit an info/warn log indicating which default was selected to aid
debugging.
