Actor Critic Thinking MCP Server
An MCP server that structures a dual-perspective review: an actor voice reflecting on intent and creative choices, and a critic voice evaluating technical execution and impact, alternating across tracked rounds into one balanced assessment. Use it for evaluating creative or strategic work, such as performances, decisions, or product concepts, where both empathetic understanding of intent and objective critique of execution matter.
What it does
This MCP server implements a structured actor-critic thinking method for evaluating creative or strategic work. It alternates between two roles across a tracked sequence of thoughts: the actor perspective, which surfaces intentions, creative choices, emotional context, and the challenges faced in making something; and the critic perspective, which evaluates technical execution, effectiveness, and likely audience impact. Each call submits one perspective's content along with a thought number and a declared total, which must be odd and at least 3 so the sequence always ends on a role, plus a flag for whether another round is needed, letting the model build up a multi-round dialogue rather than a single one-shot judgment.
When to use - and when NOT to
Reach for it when a review genuinely benefits from holding two competing lenses at once: evaluating an artistic performance or creative work, analyzing the gap between what was intended and what was actually produced, running a performance review that needs both self-reflection and external evaluation, or judging a strategic decision where empathy for the reasoning and objectivity about the outcome both matter. It is not built for simple, single-axis scoring or for tasks with no meaningful subjective dimension - forcing an actor and critic alternation onto a purely factual check just adds rounds without adding insight. The tool also does not itself generate the creative work being reviewed; the demonstration prompt in the source, naming a product from a description and keywords, is an example of content to feed into the analysis, not something the server produces on its own.
Capabilities
Each call takes five parameters: content (the current analysis text from whichever role is active), role (actor or critic), nextRoundNeeded (whether another round should follow), thoughtNumber (the position in the sequence, starting at 1), and totalThoughts (the planned total, odd and at least 3). Actor-perspective content is expected to cover intentions, creative choices, emotional context, and self-reflection on the decision-making process; critic-perspective content is expected to cover technical execution, effectiveness, audience impact, and comparative, objective feedback. The server tracks rounds across calls and expects the two perspectives to alternate until nextRoundNeeded is set to false, at which point the accumulated actor and critic thoughts form one multi-dimensional, actionable assessment.

Who it's for
Reviewers and evaluators who need structured, balanced feedback on creative or strategic work - performance reviewers, creative directors assessing a campaign or product concept, and anyone building an LLM workflow that should reason from both an empathetic and an objective angle before concluding.

Parameters
Required Parameters
content(string): Current analysis content from the specified role perspectiverole(string): Perspective role, options:"actor": Actor perspective (empathetic/creative viewpoint)"critic": Critic perspective (analytical/evaluative viewpoint)
nextRoundNeeded(boolean): Whether another round of actor-critic dialogue is neededthoughtNumber(integer): Current thought number in the sequence (minimum: 1)totalThoughts(integer): Total number of thoughts planned (must be odd and >= 3)
Role Perspective Guidelines
Actor perspective should include:
- Understanding intentions, creative choices, emotional context, challenges faced
- Self-reflection on performance and decision-making process
- Explanation of creative vision and goals
Critic perspective should include:
- Technical execution analysis, effectiveness evaluation
- Audience impact assessment, comparative analysis
- Objective feedback and improvement suggestions

Example Usage
System prompt:
Your task is to generate creative, memorable, and marketable product names based on the provided description and keywords. The product names should be concise (2-4 words), evocative, and easily understood by the target audience. Avoid generic or overly literal names. Instead, aim to create a name that stands out, captures the essence of the product, and leaves a lasting impression.
User prompt:
Description: A noise-canceling, wireless, over-ear headphone with a 20-hour battery life and touch controls. Designed for audiophiles and frequent travelers. Keywords: immersive, comfortable, high-fidelity, long-lasting, convenient
Best Practices
- Start with either actor or critic perspective
- Alternate between perspectives to maintain balance
- Continue rounds until comprehensive analysis is achieved
- Focus on relevant performance aspects
- Generate balanced assessments that honor both perspectives
- Provide constructive, actionable feedback
- Only set
nextRoundNeededto false when analysis is complete
