### Description (declared)

# Oracle MCP Common

`oracle-mcp-common` is the shared Python library for Oracle MCP servers. It
provides reusable components that belong in more than one server while keeping
server-specific tools, client lifecycles, and service behavior in each server.

The library currently provides OCI SDK authentication through
`oracle_mcp_common.auth`. Future shared modules should follow the same
server-agnostic approach and expose a focused, documented public API.

## Package requirements

- Python 3.13 or later
- OCI Python SDK 2.179.0 or later
- FastMCP 3.4.5 or later in the 3.x series for the optional HTTP IDCS authentication API

An adopting server normally declares a bounded dependency on this package:

```toml
dependencies = [
  "oracle-mcp-common>=0.2.0,<0.3.0",
]
```

## Authentication module

`oracle_mcp_common.auth` resolves outbound authentication for OCI Python SDK
clients. It chooses a supported authentication type and returns the SDK-native
ingredients needed to create a service client.

The module owns credential resolution only. Each server continues to own its
OCI client type, retry and circuit-breaker policy, `additional_user_agent`, and
client lifecycle.

### Quick start

Set up OCI credentials for the authentication type you intend to use, then
build a context and pass its config and signer to the OCI SDK client.

```python
import oci

from oracle_mcp_common import build_auth_context

auth_context = build_auth_context()
config = {
    **auth_context.config,
    "additional_user_agent": "oci-example-mcp/1.2.3",
}
client = oci.object_storage.ObjectStorageClient(config, signer=auth_context.signer)
```

The returned `AuthContext` contains:

| Field | Meaning |
| --- | --- |
| `auth_type` | The selected `AuthType`; `auto` is resolved to `api_key` or `security_token`. |
| `config` | An OCI SDK config dictionary. It contains the resolved `region` when one is available. |
| `signer` | The OCI SDK signer to pass to a client constructor. |
| `tenancy_id` | Tenancy …
