CallRail MCP

get_call_transcript

Retrieve the AI-generated transcript for a call, with speaker turns, confidence scores, and durations. Requires CallScribe enabled at the time of the call.

Instructions

Get the AI transcript for a call. Requires CallRail Conversation Intelligence (CallScribe) to be enabled on the company at the time the call was placed.

If CallScribe was enabled AFTER the call, no transcript exists — CallRail does not retroactively transcribe. Returns CallRail's 404 in that case.

Args: call_id: 'CAL...' id. account_id: CallRail account ID. Auto-resolves if omitted.

Returns: JSON string with the transcription including segments (text per speaker turn), per-segment confidence scores, and durations.

Behavior5/5

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

No annotations are provided, so the description fully discloses behavior: prerequisites (CallScribe enabled at call time), error case (404 if not), and return format (JSON with segments, confidence, durations). No contradictions.

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 well-organized into purpose, condition, behavior, arguments, and returns. Each sentence is necessary and informative, with no redundant text.

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?

Despite an output schema existing, the description still details the return value (JSON string with segments, confidence, durations). It covers all aspects of the tool's usage, making it complete.

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

Parameters5/5

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

Schema description coverage is 0%, but the description explains both parameters: call_id as 'CAL... id' and account_id as 'CallRail account ID. Auto-resolves if omitted.' This adds meaning beyond the schema.

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 clearly states 'Get the AI transcript for a call', specifying the action and resource. It distinguishes from sibling tools like get_call_recording and call_summary by focusing on the transcript.

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

Usage Guidelines5/5

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

The description explicitly states when to use (when CallScribe is enabled) and when not to use (if enabled after the call, returns 404). This provides clear guidance on appropriate invocation.

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