Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v0.1.4
Disambiguation5/5
Each tool targets a specific file type and action (e.g., inspect vs read for Excel, extract vs write for Word), with no overlapping purposes. The ping tool is distinct. Even complementary tools like sqlite_inspect_database and sqlite_get_schema have clear, separate roles.
Naming Consistency4/5
Tools use a consistent filetype_verb_noun pattern (e.g., excel_inspect_file, word_extract_text). The verb choice varies across file types (inspect, read, get, query, extract, write), but within each group the pattern is predictable. The lone ping tool lacks a prefix, breaking the pattern slightly.
Tool Count5/5
12 tools is well within the ideal range. Each file type has a focused set (Excel:2, PDF:1, SQLite:3, Word:5) that covers essential operations without overloading the server. No tool feels redundant or unnecessary.
Completeness4/5
The server covers inspection, reading, and extraction for Excel, PDF, SQLite, and Word, plus Word write. Missing write operations for Excel, PDF, and SQLite, but the server's focus seems read-only. There is no tool for CSV or other formats, but the current scope is reasonably complete.
Average 3.8/5 across 12 of 12 tools scored. Lowest: 3.1/5.

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

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It mentions truncation for large data, which is useful, but lacks other important details such as error handling (e.g., file not found), encoding, permissions, or whether the tool modifies the file. The description adds minimal value beyond basic purpose.
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 very concise with two sentences. The first sentence clearly states the purpose, and the second adds a key behavioral note about truncation. No unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema, return values are covered. However, the description lacks information about error scenarios (file not found, sheet not found), performance, and does not mention the sibling tool for inspection. It is adequate for basic use but not fully comprehensive.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the input schema already documents both parameters adequately. The description does not add any extra information about parameters (e.g., format constraints, examples). Baseline score of 3 is appropriate as the description is neutral.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb '读取' (read) and resource 'Excel 工作表内容' (Excel sheet content), with output format JSON. It specifies it supports reading a single sheet. However, it does not differentiate from the sibling tool 'excel_inspect_file', which might inspect structure rather than content.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like excel_inspect_file. The only usage hint is about truncation for large data, but no explicit when-to-use or when-not-to-use context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are available, so the description must cover behavioral traits. It fails to mention that only .docx files are supported (this is only in the schema), and it is unclear whether images are saved to the output directory or just metadata is returned. The description implies reading but lacks details on file system impact or error conditions.
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 very concise (two sentences) and front-loaded with the key action. Every sentence provides essential information without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with two parameters and an output schema, the description covers the basic purpose and output fields. However, it lacks usage guidance and behavioral transparency, which are needed for complete context. Score reflects adequacy with clear gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, with both parameters having descriptions. The tool description does not add additional meaning beyond the schema; it focuses on output fields. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'extract' and resource 'images from Word documents'. It distinguishes from sibling tools like word_extract_tables and word_extract_text by focusing on images. However, it does not explicitly differentiate itself from these siblings in the description.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. It does not mention that for text or tables one should use the respective word_extract tools, nor does it state prerequisites or context for extraction.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must disclose behavioral traits. It only states that it extracts all tables and supports two output formats, but does not mention whether the operation is non-destructive, error handling, or limitations (e.g., only .docx files are supported, though this is in the schema).
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 two sentences, front-loaded with the core purpose, and every sentence adds value. There is no unnecessary information, making it efficiently concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple, and the schema covers parameters and output. However, the description lacks details on return behavior, edge cases (e.g., no tables found), and error handling, leaving some contextual gaps despite having an output schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, with both parameters having descriptions. The description adds minimal extra meaning beyond the schema, merely restating the output format options. Therefore, the baseline score of 3 is appropriate.
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 '提取 Word 文档中的所有表格' (Extract all tables from Word document), specifying the verb and resource. It distinguishes from sibling tools like word_extract_text (text extraction) and word_extract_images (image extraction) by focusing specifically on tables.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no explicit guidance on when to use this tool versus alternatives. The usage context is implied by the tool's purpose, but no when-not or alternative recommendations are given, which is a gap for an AI agent.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so description carries full burden. It only mentions creating a document and adding title, but fails to disclose whether file_path overwrites existing files, required permissions, or output behavior.
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?
Two sentences, zero waste. Purpose is front-loaded and efficiently conveyed.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Adequate for a simple write tool with output schema, but misses behavioral details like file overwrite handling, making it slightly incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. Description adds minimal extra meaning (title becomes document title), but doesn't elaborate beyond 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 '将内容写入 Word 文档' (write content to Word document) and specifies it creates a new document, differentiating it from read-only siblings like word_extract_text.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not explicitly guide when to use this tool versus alternatives. While the name suggests writing, no mention of contexts like overwrite behavior or file existence is given.
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?
No annotations are provided, so the description must cover behavioral aspects. It states extraction behavior and page separation but does not discuss edge cases like encrypted files, performance, or error handling.
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?
Two sentences, no filler, front-loaded with the core purpose. Every word contributes meaning.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With output schema present and clear parameter descriptions, the description is largely complete. Could mention output format or limitations, but not essential given the output schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% and descriptions in schema are already informative. The tool description adds minimal extra context beyond what's in the schema (e.g., '1-based' for page_range).
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 the tool extracts text from PDF files, with options for all pages or a range. The name 'pdf_extract_text' is specific and distinguishes it from siblings like 'word_extract_text'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explains when to use it (PDF text extraction) but lacks explicit guidance on when not to use it or comparisons to alternatives. It indicates support for page ranges but no exclusion criteria.
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?
No annotations provided, so description carries full burden. Describes it as a schema retrieval operation; read-only nature is implied but not explicitly stated. 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?
Very concise two-sentence description. Front-loaded with core purpose and critical usage hint. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With 2 well-described parameters and output schema available, the description provides necessary context (core tool, prerequisite). Complete for its purpose, though behavioral transparency could be enhanced.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with each parameter having a basic description. The description adds no additional meaning beyond the schema, earning a baseline score.
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 it retrieves SQLite table schema (field name to type mapping). Identifies as a core tool and prerequisite for writing SQL, distinguishing it from sibling tools like sqlite_inspect_database and sqlite_query.
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 states 'LLM must see schema before writing SQL', providing clear context for when to use. Lacks explicit exclusions or alternatives but effectively implies use before queries.
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?
No annotations provided, so description carries full burden. It discloses security feature (parameterized queries) and query type restriction, but lacks details on error handling or read-only nature beyond the SELECT restriction.
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?

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With output schema present, return format is covered. Description is sufficient for a simple read-only query tool, though it could mention reading from file system explicitly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so parameters are well-documented in schema. Description adds only the security note about parameterized queries, which provides marginal additional value beyond 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 the tool executes SQL queries and returns JSON, explicitly limiting to SELECT queries. This distinguishes it from siblings like sqlite_get_schema.
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?
It explicitly restricts to SELECT queries and mentions parameterized queries for SQL injection prevention, providing clear usage boundaries. It could further contrast with sibling tools for when to use alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses output behavior: text extraction with table-to-Markdown conversion and document order preservation. With no annotations, this provides reasonable transparency for a read-only extraction tool, though it doesn't address potential limitations like large files or formatting loss.
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?
Two sentences with no wasted wording. First sentence states main purpose, second adds key details on output format and order, making it highly efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple single-parameter tool and existence of an output schema, the description sufficiently covers what the tool does and its output. Minor gaps (e.g., error handling, encoding) are acceptable for this low-complexity tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% and the parameter description is comprehensive, so the tool description does not need to add further parameter details. Baseline score of 3 is appropriate as no additional meaning is provided 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?
Description clearly states it extracts complete text from Word documents and specifies output format (paragraphs and tables in order, tables as Markdown). It distinguishes itself from sibling tools like word_extract_images and word_extract_tables by focusing on full text extraction.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use versus alternatives. While the output description implies its scope, it does not state exclusions or provide direct comparisons to sibling tools, leaving the agent to infer usage context.
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?
No annotations provided, so description bears responsibility. Describes behavior as inspecting and returning comprehensive statistics, but lacks details on side effects, permissions, or performance. Adequate but not exhaustive.
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?
Three sentences, each adding value: purpose, content, usage guidance. Front-loaded and no wasted words. Efficient structure.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 3 parameters and existence of output schema, description covers purpose, usage guidance, and basic behavior. Could mention output schema structure or error handling, but still fairly complete for an inspection tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
