Why teams connect Anthropic and PostgreSQL

Sync the records in PostgreSQL into Anthropic and land its embeddings, classifications, and generated fields back on the same rows, in real time and without a pipeline to maintain.

Anthropic is a read-only source: Stacksync reads its data in real time and delivers it into PostgreSQL, so PostgreSQL always reflects the current state of Anthropic — without exports, scripts, or schedulers.

AI systems do not hold customers or invoices the way business apps do. What they hold is derived from your data: the vectors and metadata in a vector store, or the classifications, extracted fields, and generated text a model produces over records it was given. PostgreSQL is where those source records actually live. The bridge between the two is the row itself, since an item in Anthropic and the record in PostgreSQL it describes are two halves of the same thing, and they drift the moment one is updated without the other.

Stacksync syncs Sequences, Custom Types and Enums, Tables, Views in PostgreSQL with Message Batches, Models, Usage Report (messages), Cost Report in Anthropic in real time. Rows created or changed in PostgreSQL flow into Anthropic so inference and embedding run on current data, and the scores, labels, and generated fields Anthropic produces flow back onto the matching rows in PostgreSQL, mapped field by field. A change on either side appears on the other within seconds, with no extraction job or webhook plumbing to keep alive.

Because matching is by a stable identifier, every row in PostgreSQL stays tied to its AI-side counterpart in Anthropic. Retrieval, enrichment, and generated content always resolve back to the record they came from, so there are no orphaned vectors and no labels describing a version of a row that no longer exists.

Common use cases

  • 01 Load Message Batches status and results into a database so downstream jobs consume completed batch output by custom_id.
  • 02 Snapshot the Models catalog into a config table so applications resolve current model IDs and context windows without hardcoding.
  • 03 Feed reporting and BI from a continuously synced Postgres replica instead of scheduled ETL scripts
  • 04 Expose SaaS objects (CRM contacts, ERP invoices, support tickets) as Postgres tables that internal tools can query and join

Common sync patterns

Keep derived data fresh as sources change

When a row in PostgreSQL is updated or removed, its counterpart in Anthropic is updated or removed too, so nothing in Anthropic describes a record that has since changed or gone.

Backfill once, then stay in step

Load your existing rows from PostgreSQL into Anthropic to build the index or enrichment set, then let ongoing changes sync automatically instead of re-running the whole job.

One record, one identifier

Each item in Anthropic carries the key of the row in PostgreSQL it came from, so results resolve back to the exact record with nothing orphaned or duplicated.

What you can sync between Anthropic and PostgreSQL

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Anthropic objects PostgreSQL objects How this pairing syncs
API Keys Key metadata — name, owning workspace, status, creator — from /v1/organizations/api_keys; the secret value is never returned. Read-only, useful for a security key inventory. Schemas Namespaces that scope which tables a sync reads and writes. API Keys is specific to Anthropic and Schemas to PostgreSQL — each maps to any object or custom field on the other side.
Invites Pending organization invitations from /v1/organizations/invites; read to track who has been invited to the org but has not yet accepted. Columns Field-level mapping targets; types are mapped to the connected system's field types. Invites is specific to Anthropic and Columns to PostgreSQL — each maps to any object or custom field on the other side.
Message Batches Asynchronous batch jobs at /v1/messages/batches; the connector polls processing_status and reads per-request results keyed by custom_id once a batch has ended. Primary and Unique Keys Used as match keys for idempotent upserts and conflict resolution. Message Batches is specific to Anthropic and Primary and Unique Keys to PostgreSQL — each maps to any object or custom field on the other side.
Models Claude model catalog from /v1/models with model IDs, context window, max output, and capability flags; snapshotted into a config table so applications avoid hardcoding model IDs. JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata. Models is specific to Anthropic and JSONB Columns to PostgreSQL — each maps to any object or custom field on the other side.
Usage Report (messages) Time-bucketed token usage (uncached input, cached input, cache creation, output) grouped by workspace, model, API key, and service tier from /v1/organizations/usage_report/messages; read-only, queried by date range at 1m/1h/1d bucket width. Sequences Generate surrogate keys for rows created by inbound syncs. Usage Report (messages) is specific to Anthropic and Sequences to PostgreSQL — each maps to any object or custom field on the other side.
Cost Report Daily USD cost broken down by workspace, model, and cost type from /v1/organizations/cost_report; read-only, polled by date range for chargeback and FinOps reporting. Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields. Cost Report is specific to Anthropic and Custom Types and Enums to PostgreSQL — each maps to any object or custom field on the other side.

How changes propagate between Anthropic and PostgreSQL

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Anthropic PostgreSQL Interval-based propagation

DetectionStacksync polls Anthropic for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

DeliveryEach detected change is applied to PostgreSQL as a row-level write, with types converted between the two schemas.

PostgreSQL Anthropic Sub-second propagation

DetectionChanges in PostgreSQL are captured at the source via change data capture — no polling loop against its API. Logical replication (wal_level = logical) for change data capture via the "Postgres" connector.

DeliveryAnthropic does not accept inbound record writes, so this direction carries requests rather than records: Anthropic's output flows back as field updates on the originating PostgreSQL records.

Rate-limit considerations

  • Anthropic: Messages API limits are per usage tier: requests-per-minute plus input- and output-tokens-per-minute, surfaced in anthropic-ratelimit-* response headers with retry-after on 429. Usage/cost reports recommend polling at most once per minute.
  • PostgreSQL: No API rate limits; throughput is bounded by connection limits, instance resources, and replication slot throughput.

How the Anthropic and PostgreSQL connectors work

Anthropic

Integration surface
REST — Messages API at api.anthropic.com/v1 plus the Admin API (/v1/organizations/*) for organization, usage, and cost data
Authentication
API key in the x-api-key header for Messages, Models, Files, and Batches endpoints; the Admin API requires a separate Admin API key (sk-ant-admin...) with organization-admin permission. Every request also sends an anthropic-version header.
Change detection
Polling. Usage and cost reports are queried by time bucket (1m/1h/1d) over a date range; list endpoints paginate with has_more/next_page (or after_id). No general-purpose data-change webhooks (webhooks exist only for Managed Agents session state).
Capabilities
read
Rate limits
Messages API limits are per usage tier: requests-per-minute plus input- and output-tokens-per-minute, surfaced in anthropic-ratelimit-* response headers with retry-after on 429. Usage/cost reports recommend polling at most once per minute.

PostgreSQL

Integration surface
SQL wire protocol (PostgreSQL frontend/backend protocol)
Authentication
Database credentials (connection string or parameters), with optional SSL root certificate upload and optional SSH tunnel (SSH user + host); a least-privilege DB user
