# export_ai_log_otel [MAINTENANCE] R2-G — Run ONE bounded export pass of new ai_log_events to the configured OTel/Langfuse-compatible OTLP endpoint for a project, resuming from the durable watermark left by the previous pass. Always safe to call: returns {"status": "disabled"} immediately if MERIDIAN_AI_LOG_OTEL_ENABLED (or this project's own override) is off, {"status": "unavailable"} if the optional opentelemetry client library isn't installed or no endpoint is configured, {"status": "idle"} if there is nothing new to export, {"status": "sent"} on full success, {"status": "degraded"} if part of the batch sent before a chunk exhausted its bounded retries (the watermark still advanced past every chunk that DID send — no silent gaps), or {"status": "sync_failed"}/{"status": "error"} if nothing sent this pass. NEVER raises, never blocks the caller longer than a bounded overall deadline, and never mutates or deletes any ai_log_events row — Meridian's own DB stays authoritative regardless of outcome. Returns {project_id, status, sent_count, batch_size, reason}. Persistent-state disclosure: on hosted Meridian, supplied text and project/session metadata -- including task log entries, pinned decisions, sprint items, notes, handoff/goal state, and HITL queue items -- are sent to and stored in Meridian's service, in an isolated per-tenant Postgres database (Neon); self-hosted deployments keep the same categories in the configured local SQLite/Postgres database. This data is visible in the dashboard and API, and may resurface in later project context or handoffs. Notes and pinned decisions can be deleted individually; task log entries and sprint items can be deleted via the dashboard/API (not exposed as an agent-facing tool); HITL queue items and handoff state have no per-record delete. Full removal of any of this data is available via project or account deletion, using the documented controls. Do not include secrets.

Default from MERIDIAN_AI_LOG_OTEL_BATCH_SIZE (200), hard-capped at 1000. | | `project_id` | string | no | | | `project_name` | string | no | Project name — an alternative to project_id; resolved to the id internally. project_id wins if both are given. | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "export_ai_log_otel", "arguments": {} } } ``` ## Why export_ai_log_otel is rated Medium An AI agent can call export_ai_log_otel faster than any human can review: one bad instruction and it creates or modifies resources in Meridian by the hundred, each call as confident as the last. Risk signals: Bulk/mass operation — affects multiple targets ## Use case AI agents use export_ai_log_otel to create or update resources in Meridian, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Meridian environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
