CallRail MCP

delete_tracker

Disable a tracker to prevent new calls while retaining its call history. The phone number is released.

Instructions

Delete (disable) a tracker. Soft-removes it from active trackers; the tracker keeps its call history but stops receiving new calls. The underlying phone number is released.

Args: tracker_id: 'TRK...' id. account_id: Auto-resolves if omitted.

Returns: An object with deleted: True, tracker_id, and response (CallRail's body, which on success contains the disabled tracker record including disabled_at timestamp). Empty object if CallRail returned 204.

Behavior5/5

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

No annotations provided, so description fully carries burden. Discloses soft-removal, retained call history, stopped new calls, phone number release, auto-resolve for account_id, and return value structure.

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

Conciseness4/5

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

Well-structured with separate sections for action, args, returns. Some redundancy (e.g., 'An object with' could be trimmed), but each sentence adds value.

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?

Given output schema exists, description completes the picture with details on soft-removal behavior and edge cases (204 response). Adequate for a delete operation.

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

Parameters4/5

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

Schema has 0% description coverage. Description adds meaning: tracker_id format 'TRK...' and account_id auto-resolves if omitted. Lacks account_id format details, but overall helpful.

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?

Clearly states 'delete (disable) a tracker' with specific verb and resource. Differentiates from sibling tools like create_tracker, update_tracker, and list_trackers by explaining soft-removal semantics.

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?

Explicitly describes the effect of soft-removal and when to use (to disable a tracker). Lacks explicit when-not or alternative tools, but the context is clear enough for an agent to decide.

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