DeepSeek Subagent MCP Server
DeepSeek Subagent MCP Server
Servidor MCP que permite a Codex (o a cualquier cliente MCP) delegar subtareas a DeepSeek como subagente.
Una única herramienta deepseek_task: dale una tarea (+ contexto opcional) y recibe la respuesta final de DeepSeek.

Available Tools
1 tooldeepseek_taskA
Delegate a sub-task to DeepSeek as a sub-agent and get back its result. Use this for work that can be done independently: research, drafting, code review, refactoring, analysis, writing, or any self-contained task that shouldn't pollute the main conversation. The caller (Codex) supplies a task description and optional context; DeepSeek completes the task in one shot and returns the final answer (with reasoning, if produced). Default model: deepseek-v4-flash. Override via DEEPSEEK_MODEL env (e.g. DeepSeek-V4-Pro-0813).
| Name | Required | Description | Default |
|---|---|---|---|
| task | Yes | The sub-task for DeepSeek to complete. Be specific: what to do, what format the result should take. | |
| system | No | Optional custom system prompt overriding the default subagent persona. | |
| context | No | Optional context material the sub-agent should consider (code snippets, file contents, notes). | |
| max_tokens | No | Maximum output tokens. | |
| temperature | No | Sampling temperature (0-2). Omit to use the model default. | |
| reasoning_effort | No | Thinking effort for DeepSeek V4 reasoning mode. Omit to use the model default. |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of explaining behavior. It does this well: it clarifies the one-shot execution model, the return style ('returns the final answer (with reasoning, if produced)'), and the default/environment-configurable model. It doesn't cover failure modes or side effects, but the behavior of a delegation tool is well-scoped.
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 modestly long but every sentence carries weight: the first defines the operation and result, the second clarifies the use cases and scope, and the third provides model configuration with an override example. It is structured and front-loaded, without filler.
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?
The tool is a one-shot delegation with no output schema and no siblings. The description adequately conveys its oracle-style behavior, expected result, and the extent of inputs. It could give example output shape or failure handling, but not that could be unique; the essentials are present.
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 coverage is 100%, so all parameters are already documented. The description restates some parameter-level guidance ('supplies a task description and optional context') but adds no new meaning beyond the schema. The mention of the env-var model override is useful but relates to configuration rather than the input parameters. Baseline 3 is appropriate.
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 ('Delegate'), a clear resource ('sub-task to DeepSeek as a sub-agent'), and explicitly frames the return value ('get back its result'). It further distinguishes the tool by noting the work is done independently as a sub-agent without polluting the main conversation — making the purpose unambiguous.
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 provides a clear list of when the tool is appropriate (research, drafting, code review, refactoring, analysis, writing, any self-contained task) and states that it is for independent work. It does not explicitly list exclusions or alternatives, but there are no sibling tools to differentiate from, so the guidance is contextually sufficient.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Scored across 1 tool
There is only one tool, so there is no possibility of confusion or overlapping purposes. The tool clearly covers the single action of delegating a sub-task to DeepSeek.
With a single tool, there is no pattern to be inconsistent about. The name 'deepseek_task' is descriptive and follows a clear noun-based naming convention.
One tool is on the thin side; while the server's purpose is narrow, a richer integration might include multiple tools (e.g., different task types or configuration options). The count is borderline but not unreasonable for a single-purpose sub-agent server.
The tool fully covers the stated purpose of delegating a self-contained task and returning the result. Minor gaps exist, such as no way to manage task history or configure multiple output modes, but these are not essential to the core workflow.
