# set_ai_log_export_config

[MAINTENANCE] R2-G — Set per-project override config for the OPTIONAL AI-log -> OTel/self-hosted-Langfuse export adapter. Every field is optional and left-as-is when omitted (partial upsert). 'enabled=false' force-disables export for THIS project even when the global MERIDIAN_AI_LOG_OTEL_ENABLED flag is on; 'enabled=true' or omitted defers to the global flag — a project can never turn export on when the operator has globally disabled it. 'otlp_endpoint' must be an http:// or https:// URL and is validated against this codebase's shared secret/path checks (meridian.secret_redaction.check_for_secrets + meridian.capability_manifest's embedded-credential/absolute-path patterns) — rejected with a ValueError if it looks like it carries a bearer token, embedded basic-auth credentials, or a machine-local path. An OTLP auth header/API key is NEVER accepted here — set the MERIDIAN_AI_LOG_OTEL_HEADERS environment variable on the server instead; there is no field on this tool or column in storage for it. 'langfuse_compat=true' is a purely informational hint (adds a resource attribute, shown in get_ai_log_export_status) for pointing otlp_endpoint at a self-hosted Langfuse OTLP-compatible ingestion endpoint — it does not change the wire protocol. 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.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `enabled` | boolean | no | Per-project override. false force-disables even if the global flag is on; true/omitted defers to the global flag. |
| `protocol` | string | no | Documentation-only label; both send the same OTLP/HTTP wire format. |
| `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. |
| `service_name` | string | no | OTel resource service.name override for this project's exported events. |
| `otlp_endpoint` | string | no | http:// or https:// OTLP logs endpoint override for this project. Validated — never a secret-shaped or embedded-credential URL. |
| `langfuse_compat` | boolean | no | Informational hint only — set true when otlp_endpoint points at a self-hosted Langfuse OTLP-compatible ingestion endpoint. |

## Why set_ai_log_export_config is rated Medium

An AI agent can call set_ai_log_export_config 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 set_ai_log_export_config 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)
