Send sequence test messages

sequences_send_test
Destructive

Sends up to five selected saved Sequence emails to one explicit test address. This does not enroll a Subscriber, start the Sequence, or write delivery activity. Effect: external-email. Retry with the same idempotency_key. Permissions: live_actions:write, subscribers:read, sequences:write. API reference: https://mailrith.com/developers/api-reference.

TDQS

A4.5/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description substantially expands on the annotations by stating 'Effect: external-email', listing required permissions, and clarifying that no delivery activity is written. This helps reconcile the destructiveHint: true annotation with the actual external side effect rather than implying destructive internal data changes.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and front-loaded with the core operation, then efficiently lists exclusions, external effect, idempotency guidance, permissions, and API reference. Every sentence adds value and there is no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers purpose, what the tool does not do, external side effects, retry behavior, required permissions, and includes an API reference. With an output schema present, no essential information for selecting and invoking this tool is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so sequence_id, body, idempotency_key, and nested fields like recipient, message_ids, and subscriber_id are already well documented in the schema. The description adds no per-parameter detail, but that is acceptable given the schema already carries the semantic load.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb and resource: 'Sends up to five selected saved Sequence emails to one explicit test address.' It clearly identifies what the tool does and distinguishes it from other send_test siblings by scoping to Sequence emails, while also noting what it does not do ('does not enroll a Subscriber, start the Sequence, or write delivery activity').

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives clear context for when to use this test-only tool, including explicit non-actions and a retry instruction: 'Retry with the same idempotency_key.' It does not directly name sibling alternatives like automations_send_test or broadcasts_send_test, but the Sequence scope and the stated exclusions make the appropriate usage clear enough.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A3.8/5.0
Disambiguation5/5

Every tool is prefixed by its resource and targets a unique action, so there is no real overlap between tools. Even similar operations like preflight, preview_journey, and send_test are clearly separated by resource and described with distinct effects.

Naming Consistency5/5

All tools follow a consistent `resource_action` snake_case pattern, e.g., broadcasts_create, subscribers_upsert, sequences_update_status. Custom verbs like cancel, unschedule, and preview_journey still fit the same predictable convention.

Tool Count1/5

55 tools is an extreme count for a single MCP server, making it difficult for an agent to efficiently discover and choose among the surface. While each tool appears justified, the size suggests the API should be split into focused servers by resource domain.

Completeness3/5

The broadcast, automation, sequence, and subscriber workflows are well covered with lifecycle operations. However, custom fields and segments only have read/list/preview operations with no create, update, or delete, and several resources lack delete endpoints, leaving notable gaps for full lifecycle management.
