MCP Tools Reference: firestore.googleapis.com

Tool: list_databases

List Firestore databases.

The following sample demonstrate how to use curl to invoke the list_databases MCP tool.

Curl Request 
                  
curl --location 'https://firestore.googleapis.com/mcp' \
--header 'content-type: application/json' \
--header 'accept: application/json, text/event-stream' \
--data '{
  "method": "tools/call",
  "params": {
    "name": "list_databases",
    "arguments": {
      // provide these details according to the tool's MCP specification
    }
  },
  "jsonrpc": "2.0",
  "id": 1
}'

Input Schema

A request to list the Firestore Databases in all locations for a project.

ListDatabasesRequest

JSON representation 
{
  "parent": string,
  "showDeleted": boolean
}
Fields
parent

string

Required. A parent name of the form projects/{project_id}
showDeleted

boolean

If true, also returns deleted resources.

Output Schema

The list of databases for a project.

ListDatabasesResponse

JSON representation 
{
  "databases": [
    {
      object (Database)
    }
  ],
  "unreachable": [
    string
  ]
}
Fields
databases[]

object (Database)

The databases in the project.
unreachable[]

string

In the event that data about individual databases cannot be listed they will be recorded here.

An example entry might be: projects/some_project/locations/some_location This can happen if the Cloud Region that the Database resides in is currently unavailable. In this case we can't fetch all the details about the database. You may be able to get a more detailed error message (or possibly fetch the resource) by sending a 'Get' request for the resource or a 'List' request for the specific location.

}
Fields
name

string

The resource name of the Database. Format: projects/{project}/databases/{database}
uid

string

Output only. The system-generated UUID4 for this Database.
createTime

string (Timestamp format)

Output only. The timestamp at which this database was created. Databases created before 2016 do not populate create_time.

Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z", "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30".
updateTime

string (Timestamp format)

Output only. The timestamp at which this database was most recently updated. Note this only includes updates to the database resource and not data contained by the database.

Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z", "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30".
deleteTime

string (Timestamp format)

Output only. The timestamp at which this database was deleted. Only set if the database has been deleted.

Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z", "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30".
locationId

string

The location of the database. Available locations are listed at https://cloud.google.com/firestore/docs/locations.
type

enum (DatabaseType)

The type of the database. See https://cloud.google.com/datastore/docs/firestore-or-datastore for information about how to choose.
concurrencyMode

enum (ConcurrencyMode)

The concurrency control mode to use for this database.

If unspecified in a CreateDatabase request, this will default based on the database edition: Optimistic for Enterprise and Pessimistic for all other databases.
versionRetentionPeriod

string (Duration format)

Output only. The period during which past versions of data are retained in the database.

Any read or query can specify a read_time within this window, and will read the state of the database at that time.

If the PITR feature is enabled, the retention period is 7 days. Otherwise, the retention period is 1 hour.

A duration in seconds with up to nine fractional digits, ending with 's'. Example: "3.5s".
earliestVersionTime

string (Timestamp format)

Output only. The earliest timestamp at which older versions of the data can be read from the database. See [version_retention_period] above; this field is populated with now - version_retention_period.

This value is continuously updated, and becomes stale the moment it is queried. If you are using this value to recover data, make sure to account for the time from the moment when the value is queried to the moment when you initiate the recovery.

Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z", "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30".

Whether to enable the PITR feature on this database.
appEngineIntegrationMode

enum (AppEngineIntegrationMode)

The App Engine integration mode to use for this database.

Output only. The key_prefix for this database. This key_prefix is used, in combination with the project ID ("~") to construct the application ID that is returned from the Cloud Datastore APIs in Google App Engine first generation runtimes.

This value may be empty in which case the appid to use for URL-encoded keys is the project_id (eg: foo instead of v~foo).
deleteProtectionState

enum (DeleteProtectionState)

State of delete protection for the database.
cmekConfig

object (CmekConfig)

Optional. Presence indicates CMEK is enabled for this database.
previousId

string

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
etag

string

This checksum is computed by the server based on the value of other fields, and may be sent on update and delete requests to ensure the client has an up-to-date value before proceeding.
databaseEdition

enum (DatabaseEdition)

Immutable. The edition of the database.
realtimeUpdatesMode

enum (RealtimeUpdatesMode)

Immutable. The default Realtime Updates mode to use for this database.
firestoreDataAccessMode

mongodbCompatibleDataAccessMode

enum (DataAccessMode)

Optional. The MongoDB compatible API data access mode to use for this database. If not set on write, the default value is DATA_ACCESS_MODE_ENABLED for Enterprise Edition. The value is always DATA_ACCESS_MODE_DISABLED for Standard Edition.

Union field _free_tier.

_free_tier can be only one of the following:
freeTier

boolean

Output only. Background: Free tier is the ability of a Firestore database to use a small amount of resources every day without being charged. Once usage exceeds the free tier limit further usage is charged.

Whether this database can make use of the free tier. Only one database per project can be eligible for the free tier.

The first (or next) database that is created in a project without a free tier database will be marked as eligible for the free tier. Databases that are created while there is a free tier database will not be eligible for the free tier.

Timestamp

JSON representation 
{
  "seconds": string,
  "nanos": integer
}
Fields
seconds

string (int64 format)

Represents seconds of UTC time since Unix epoch 1970-01-01T00:00:00Z. Must be between -62135596800 and 253402300799 inclusive (which corresponds to 0001-01-01T00:00:00Z to 9999-12-31T23:59:59Z).
nanos

integer

Non-negative fractions of a second at nanosecond resolution. This field is the nanosecond portion of the duration, not an alternative to seconds. Negative second values with fractions must still have non-negative nanos values that count forward in time. Must be between 0 and 999,999,999 inclusive.

Duration

JSON representation 
{
  "seconds": string,
  "nanos": integer

nanos

integer

Signed fractions of a second at nanosecond resolution of the span of time. Durations less than one second are represented with a 0 seconds field and a positive or negative nanos field. For durations of one second or more, a non-zero value for the nanos field must be of the same sign as the seconds field. Must be from -999,999,999 to +999,999,999 inclusive.
