MCP tools specification - Distributed Load Testing on AWS

MCP tools specification

The Distributed Load Testing solution exposes a set of MCP tools that enable AI agents to interact with test scenarios and results. These tools provide high-level, abstracted capabilities that align with how AI agents process information, allowing them to focus on analysis and insights rather than detailed API contracts.

Note

All MCP tools provide read-only access to the solution’s data. No modifications to test scenarios or configurations are supported through the MCP interface.

list_scenarios

Description

The list_scenarios tool retrieves a list of all available test scenarios with basic metadata.

Endpoint

GET /scenarios

Parameters

None

Response

testDescription

Description of the test scenario

get_scenario_details

Description

The get_scenario_details tool retrieves the test configuration and most recent test run for a single test scenario.

Endpoint

GET /scenarios/<test_id>?history=false&results=false

Request parameter

test_id
  • The unique identifier for the test scenario

    Type: String

    Required: Yes

Response

Name Description

testTaskConfigs

Task configuration for each region

testScenario

Test definition and parameters

status

Current test status

startTime

Test start timestamp

endTime

list_test_runs

Description

The list_test_runs tool retrieves a list of test runs for a specific test scenario, sorted newest to oldest. Returns a maximum of 30 results.

Endpoint

GET /scenarios/<testid>/testruns/?limit=<limit>

or

GET /scenarios/<testid>/testruns/?limit=30&start_date=<start_date>&end_date=<end_date>

Request parameters

test_id
  • The unique identifier for the test scenario

    Type: String

    Required: Yes

limit
  • Maximum number of test runs to return

    Type: Integer

    Default: 20

    Maximum: 30

    Required: No

start_date
  • ISO 8601 timestamp to filter runs from specific date

    Type: String (date-time format)

    Required: No

end_date
  • ISO 8601 timestamp to filter runs until specific date

    Type: String (date-time format)

    Required: No

Response

Name Description

testRuns

Array of test run summaries with performance metrics and percentiles for each run

get_test_run

Description

The get_test_run tool retrieves detailed results for a single test run with regional and endpoint breakdowns.

Endpoint

GET /scenarios/<testid>/testruns/<testrunid>

Request parameters

test_id
  • The unique identifier for the test scenario

    Type: String

    Required: Yes

test_run_id
  • The unique identifier for the specific test run

    Type: String

    Required: Yes

Response

Name Description

results

Complete test run data including regional results breakdown, endpoint-specific metrics, performance percentiles (p50, p90, p95, p99), success and failure counts, response times and latency, and test configuration used for the run

get_latest_test_run

Description

The get_latest_test_run tool retrieves the most recent test run for a specific test scenario.

Endpoint

GET /scenarios/<testid>/testruns/?limit=1

Note

Results are sorted by time using a Global Secondary Index (GSI), ensuring the most recent test run is returned.

Request parameter

test_id
  • The unique identifier for the test scenario

    Type: String

    Required: Yes

Response

Name Description

results

Latest test run data with the same format as get_test_run

get_baseline_test_run

Description

The get_baseline_test_run tool retrieves the baseline test run for a specific test scenario. The baseline is used for performance comparison purposes.

Endpoint

GET /scenarios/<test_id>/baseline

Request parameter

test_id
  • The unique identifier for the test scenario

    Type: String

    Required: Yes

Response

Name Description

baselineData

Baseline test run data for comparison purposes, including all metrics and configuration from the designated baseline run

get_test_run_artifacts

Description

The get_test_run_artifacts tool retrieves Amazon S3 bucket information for accessing test artifacts including logs, error files, and results.

Endpoint

GET /scenarios/<testid>/testruns/<testrunid>

Request parameters

test_id
  • The unique identifier for the test scenario

    Type: String

    Required: Yes

test_run_id
  • The unique identifier for the specific test run

    Type: String

    Required: Yes

Response

Name Description

bucketName

S3 bucket name where artifacts are stored

testRunPath

Path prefix for current artifact storage (version 4.0+)

testScenarioPath

Path prefix for legacy artifact storage (pre-version 4.0)

Note

All MCP tools leverage existing API endpoints. No modifications to the underlying APIs are required to support MCP functionality.
