# Tool Description Semantic Density Scorer MCP for AI Agents MCP

> Tool Description Semantic Density Scorer helps you audit your function definitions. It checks if your instructions are actionable and if your parameters follow a consistent pattern to prevent errors in your agent's execution.

## Description

Writing instructions for agents is a balancing act. If your descriptions are too wordy, you waste tokens and confuse the model. If your parameter names switch between snake_case and camelCase, your integration breaks. This MCP lets you audit those definitions to ensure they are precise and structurally sound. You can identify where you have too much fluff or where instructions lack clear action verbs. It also catches naming inconsistencies before they cause runtime errors in your client. By using this alongside the rest of the Vinkius catalog, you ensure every tool you build is reliable and easy for any agent to use without manual debugging.

## Tools

### analyze_naming_uniformity
Checks if your parameters follow a consistent casing style like snake_case or camelCase. It prevents parsing errors in your client.

### calculate_verb_density
Measures how many action-oriented verbs are in your text to help remove unnecessary fluff. This helps reduce token waste.

### evaluate_description_clarity
Combines density and naming checks to give you a final score on how well an agent will understand the tool.

## Prompt Examples

**Prompt:** 
```
Is this tool description clear enough?
```

**Response:** 
```
The analysis shows a functional clarity score. 

| Metric | Score |
| :--- | :--- |
| Verb Density | 0.25 |
| Naming Uniformity | 100% |
| Clarity Grade | B+ |

Your description is actionable, but adding more explicit return types would improve the grade.
```

**Prompt:** 
```
Check these parameters for consistency.
```

**Response:** 
```
I found a mismatch in your parameter list:

* **Detected Style:** `snake_case` 
* **Error:** `userAge` uses `camelCase`. 

Please rename this to `user_age` to maintain uniformity.
```

**Prompt:** 
```
How can I make this instruction more actionable?
```

**Response:** 
```
Your current text has low verb density. 

**Current:** "This tool is used for the purpose of fetching user data."
**Improved:** "Fetch user data."

Removing the filler words increases your density ratio and makes the command clearer for the agent.
```

## Capabilities

### Identify instruction fluff
Find parts of your text that add no value to the agent.

### Audit parameter naming consistency
Detect when you mix different casing styles in a single tool definition.

### Score overall description clarity
Get a weighted metric on how well an agent can interpret your instructions.

### Check for missing return types
Ensure every tool explicitly states what it returns to the client.

### Prevent parsing failures
Catch structural errors before they reach your automated integration layers.

## Use Cases

### Scaling a large toolset
You are adding 50 new tools and need to ensure they all follow the same naming rules without manual checking.

### Debugging function failures
An agent keeps failing to call a specific function, so you check if the description is too vague or lacks verbs.

### Refining prompt efficiency
You want to make your tool definitions as dense and efficient as possible to save tokens during long conversations.

### Standardizing API integrations
You need to ensure that all parameters across different tools use the same snake_case convention for downstream compatibility.

## Benefits

- Reduce parsing errors by catching casing mismatches with analyze_naming_uniformity.
- Cut down on token waste by using calculate_verb_density to strip out fluff.
- Improve agent reliability with the clarity score from evaluate_description_clarity.
- Ensure every instruction contains actionable commands for your client.
- Standardize tool definitions across your entire library of functions.

## How It Works

The bottom line is you stop guessing if your instructions are clear enough for an agent to follow.

1. Provide your tool definition or text block to your agent.
2. The MCP runs linguistic and structural audits on the content.
3. You receive a breakdown of clarity scores and naming mismatches.

## Frequently Asked Questions

**How does Tool Description Semantic Density Scorer help with function calling?**
It audits your tool definitions to ensure they are precise and structurally sound. This prevents errors during the execution phase.

**Can I use Tool Description Semantic Density Scorer to find errors in my parameters?**
Yes, it specifically checks for naming inconsistencies like mixed casing styles that can break your integration.

**Does Tool Description Semantic Density Scorer work with Cursor or VS Code?**
It works with any MCP-compatible client, including Cursor, VS Code, and Claude Desktop.

**Will Tool Description Semantic Density Scorer help me save tokens?**
Yes, by identifying unnecessary fluff in your descriptions, you can rewrite them to be more dense and efficient.

**Is Tool Description Semantic Density Scorer useful for prompt engineering?**
Absolutely. It provides a way to measure the linguistic precision of your instructions, which is core to effective prompt engineering.

**What is semantic density in the context of tool descriptions?**
Semantic density refers to the ratio of actionable information to total text length. A high-density description uses imperative verbs and provides clear return types, minimizing linguistic noise that can distract an LLM during function calling.

**How does the `analyze_naming_uniformity` tool work?**
The `analyze_naming_uniformity` tool inspects an array of parameter names to detect deviations from a primary casing convention, such as `camelCase` or `snake_case`. It returns a uniformity score and identifies the detected style.

**Can this server help improve my agent's reliability?**
Yes. By using `evaluate_description_clarity`, you can identify descriptions that lack explicit return types or use ambiguous language, allowing you to refine your tools for more deterministic and reliable execution in AI clients.
