devpulse
一个 MCP 服务器,让你的 AI 编程助手能够实时查看你的开发环境状态。
当你使用 Claude Code 或 Cursor 进行调试时,AI 无法得知你的开发服务器是否正在运行、日志中出现了什么错误,或者你当前处于哪个分支。你最终不得不在每次会话中重复复制粘贴相同的上下文。devpulse 通过一次工具调用解决了这个问题。

Available Tools
3 toolsget_recent_errorsA
Returns recent ERROR and WARN log entries from the detected project's log files. Deduped, timestamped, secrets redacted. Defaults to last 50 lines.
| Name | Required | Description | Default |
|---|---|---|---|
| cwd | No | ||
| limit | No |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description covers key behaviors: returns only ERROR/WARN, deduped, timestamped, secrets redacted, defaults to last 50 lines. It does not mention idempotency or side effects, but as a read operation this is acceptable.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences are concise and front-loaded with the tool's purpose. Every word adds value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity and lack of output schema, the description covers core functionality and features. It lacks detail on return format or real-time behavior, but it is largely sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0% description coverage. The description mentions 'Defaults to last 50 lines' explaining the limit parameter, but 'cwd' (current working directory) is not explained. It adds some value beyond the bare schema but leaves ambiguity.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool returns ERROR and WARN log entries with dedup, timestamping, and secret redaction. It distinguishes itself from sibling tools (get_running_services, get_session_snapshot) which serve different purposes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for retrieving recent log errors/warnings but does not explicitly state when to use this tool versus alternatives or provide exclusions. No guidance on prerequisites or context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_running_servicesB
Lists processes running on common dev ports (3000, 4000, 5173, 8080 etc). Shows what is running and what is expected but missing.
| Name | Required | Description | Default |
|---|---|---|---|
| cwd | No |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses that the tool shows running and missing processes on specific ports, but does not mention side effects, permissions, or any limitations beyond the listed ports.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two clear sentences with no redundant information. Each sentence adds value: first states what it does, second adds the expected-but-missing aspect.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of output schema and minimal parameter documentation, the description omits important details such as return format, what 'expected but missing' means, and how the cwd parameter affects the output. More context would be beneficial for a complete understanding.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has one parameter (cwd) with no description, and schema description coverage is 0%. The description does not explain what cwd does or how it affects the results, leaving the agent with no guidance on its usage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('lists') and resource ('processes on common dev ports'), and distinguishes the tool from siblings by focusing on a specific set of ports and including expected but missing processes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies the tool is for checking processes on common dev ports, but does not explicitly state when to use it versus alternatives like get_recent_errors or get_session_snapshot, nor does it provide any exclusions or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_session_snapshotA
Returns a real-time diagnostic snapshot of the current dev environment. Includes health diagnosis, running services, recent errors, git state, and environment info. Call this first to orient yourself in the user's dev session.
| Name | Required | Description | Default |
|---|---|---|---|
| cwd | No |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It states it returns a snapshot, implying read-only and non-destructive. However, it does not explicitly mention permissions or side effects, though 'snapshot' strongly suggests a safe operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Three concise sentences: first states action, second lists contents, third gives usage advice. No redundancy, every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Well-structured but lacks parameter documentation. With no output schema, the description lists return categories but omits format details. The missing parameter explanation is a notable gap for a tool with one parameter.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has one optional parameter 'cwd' with no description and 0% schema coverage. The tool description does not mention this parameter, leaving the agent without guidance on its purpose or usage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it returns a real-time diagnostic snapshot of the current dev environment, listing specific contents. It distinguishes from siblings get_recent_errors and get_running_services as a broader orientation tool.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly instructs to 'Call this first to orient yourself in the user's dev session,' providing clear guidance on when to use this tool versus alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Tool Schema Changelog

TDQS
Scored across 3 tools
The tools have overlapping information: get_session_snapshot includes recent errors and running services, making it redundant with the other two. Descriptions help clarify usage order, but ambiguity remains.
All tools follow a consistent 'get_' prefix with clear noun phrases, forming a predictable and readable pattern.
Three tools is on the low side for a dev diagnostic server, but the snapshot tool consolidates key info, making the count reasonable for basic orientation.
The set covers errors, services, and a broad snapshot (git, env, health). Minor gaps like detailed log history or dependency checks exist, but core diagnostics are present.
