opentrace
OpenTrace is a self-hosted observability/incident investigation server for AI coding agents. It ingests application logs/metrics via an SDK, connects read-only to Postgres for database investigation, runs health checks and alert watches, and exposes its capabilities to agents through MCP tools (no UI).
Score Breakdown
⚙ Agent Friendliness
🔒 Security
README claims HTTPS via Caddy with automatic Let's Encrypt and that the server listens on localhost only. It describes rate limiting for auth endpoints, no telemetry/external calls, per-user revocable MCP tokens, and Bearer token auth for SDK ingestion. It also states Postgres access is validated as SELECT-only via SQL AST parsing with configurable timeouts/row limits. Dependency hygiene and precise secrets handling (logging/redaction) are not evidenced beyond claims; version/CVE status not provided.
⚡ Reliability
Best When
You want an AI coding assistant to query your production signals (logs/errors/DB stats/health/alerts) via MCP, with everything hosted inside your environment.
Avoid When
You cannot allow agent access to production telemetry or to an internal MCP-connected service, or you require a conventional REST/GraphQL developer API rather than MCP tools.
Use Cases
- • AI-assisted log search and distributed trace assembly
- • Error grouping by fingerprint with stack traces and impact
- • Investigate slow queries using read-only Postgres introspection and EXPLAIN plans
- • Uptime monitoring via scheduled HTTP health checks
- • Create threshold alerts (e.g., error rate, latency, request volume)
- • Assess code/deploy risk by correlating commits with production behavior
- • Generate regression tests from production error data
- • Team management (invite, revoke tokens, audit logs)
Not For
- • Running as a managed SaaS (it is self-hosted)
- • High-availability/enterprise environments without validating operational readiness (no SLA stated)
- • Direct write access to production databases (DB access described as read-only)
- • Providing a public UI/dashboard to end users (explicitly no UI)
Interface
Authentication
The README describes API key/Bearer token auth for ingestion and per-user MCP tokens; it does not describe OAuth or fine-grained OAuth scopes.
Pricing
No pricing model described; appears self-hosted.
Agent Metadata
Known Gotchas
- ⚠ Agents may need to respect tool-level constraints such as SQL SELECT-only validation, row limits, and timeouts when using database tools.
- ⚠ Because the MCP server is described as self-hosted and locally configured via .mcp.json, agents must be connected to the correct project/token for team actions.
- ⚠ No explicit idempotency/retry guidance is provided in the README; agents should avoid assuming safe re-execution of state-changing operations (e.g., creating watches/users) without confirmation.
