llm-prices-cn
Server Quality Checklist
Latest release: v1.0.1
- Disambiguation5/5
The two tools have very distinct purposes: one lists prices for LLMs, the other estimates cost for a specific request. There is no overlap.
Naming Consistency5/5Both tools follow the verb_noun pattern with underscores: 'list_llm_prices' and 'estimate_cost'. Naming is clear and consistent.
Tool Count4/5With only 2 tools, the server is tightly scoped to the core functionality of querying prices and estimating costs. While minimal, it covers the essential needs.
Completeness4/5For the stated domain of LLM price lookup and cost estimation, the tools cover listing prices and computing costs. Missing potentially useful features like batch estimation or historical prices, but core functionality is present.
Average 4.1/5 across 2 of 2 tools scored.

How to sync the server with GitHub?
Servers are automatically synced at least once per day, but you can also sync manually at any time to instantly update the server profile.
To manually sync the server, click the "Sync Server" button in the MCP server admin interface.
How is the quality score calculated?
The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).
Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.
Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).
Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.
Tool Scores
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations present, so description carries full burden. It states prices are daily-verified and lists filters, but lacks details on authentication, rate limits, or response structure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely concise: one-line summary plus two parameter descriptions. Front-loaded, no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Adequate for a simple listing tool, but lacks description of output format or return value, which would help an agent interpret results.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, description adds meaning: vendor filter with examples ('deepseek', 'openai'), currency options ('CNY' default, 'USD'). However, it doesn't specify behavior when vendor is omitted.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states 'List daily-verified LLM API prices' with specific verb and resource, and distinguishes from sibling 'estimate_cost' which computes costs.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Description mentions optional filters but does not explicitly state when to use versus 'estimate_cost' or provide exclusions. Usage is implied but not directly guided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description reveals the core behavior but omits details on output format, error handling, and whether costs are approximate or exact. It doesn't disclose if there are any side effects or limitations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, front-loaded with purpose, and structured as a clear param list. Every sentence adds value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
While the tool is simple, there is no output schema, and the description does not specify the return format or error scenarios. For a cost estimation tool, mentioning the output unit (e.g., cost amount and currency) would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, yet the description explains each parameter's role and source (model_id from list_llm_prices, token counts, currency default). This fully compensates for the missing schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool estimates cost for a single request given model and token counts. It distinguishes itself from the sibling tool list_llm_prices by specifying that model_id should come from that list.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
It explicitly directs to use model_id from list_llm_prices and mentions default currency. However, it does not explicitly state when not to use this tool or compare with alternatives beyond the sibling reference.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
