通用用法

一旦与任何客户端配置完成,即可使用相同的两个工具:

  1. 询问一般问题:“此代码库中使用了哪些身份验证模式?”

  2. 分析特定文件:“审查这些身份验证文件是否存在安全问题”

服务器实现是相同的 - 只有客户端配置不同!

⚙️ 配置

超时配置

默认情况下,Gemini Bridge 对所有 CLI 操作使用 60 秒的超时时间。对于更长的查询(大文件、复杂分析),您可以使用 GEMINI_BRIDGE_TIMEOUT 环境变量配置自定义超时时间。

配置示例:

# Add with custom timeout (120 seconds)
claude mcp add gemini-bridge -s user --env GEMINI_BRIDGE_TIMEOUT=120 -- uvx gemini-bridge
{
  "mcpServers": {
    "gemini-bridge": {
      "command": "uvx",
      "args": ["gemini-bridge"],
      "env": {
        "GEMINI_BRIDGE_TIMEOUT": "120"
      }
    }
  }
}

超时选项:

  • 默认:60 秒(如果未配置)

  • 范围:任何正整数(秒)

  • 单次调用覆盖:为任一工具提供 timeout_seconds 以进行一次性扩展

  • 推荐:大文件分析建议 120-300 秒

  • 无效值:回退到 60 秒并发出警告

🛠️ 可用工具

consult_gemini

用于简单查询的直接 CLI 桥接。

参数:

  • query (string):发送给 Gemini 的问题或提示

  • directory (string):查询的工作目录

  • model (string, 可选):使用的模型 - "flash", "pro", "flash-lite", "2.5-lite", "3-pro", "3-flash", "3.1-pro", "3.1-flash-lite", 或 "auto" (默认: "flash")

  • timeout_seconds (int, 可选):覆盖此请求的执行超时时间

示例:

consult_gemini(
    query="Find authentication patterns in this codebase",
    directory="/path/to/project",
    model="flash"
)

consult_gemini_with_files

带有文件附件的 CLI 桥接,用于详细分析。

参数:

  • query (string):发送给 Gemini 的问题或提示

  • directory (string):查询的工作目录

  • files (list):相对于目录的文件路径列表

  • model (string, 可选):使用的模型 - "flash", "pro", "flash-lite", "2.5-lite", "3-pro", "3-flash", "3.1-pro", "3.1-flash-lite", 或 "auto" (默认: "flash")

  • timeout_seconds (int, 可选):覆盖此请求的执行超时时间

  • mode (string, 可选):"inline"(默认,流式传输文件内容)或 "at_command"(让 Gemini CLI 自行解析 @path 引用)

示例:

consult_gemini_with_files(
    query="Analyze these auth files and suggest improvements",
    directory="/path/to/project",
    files=["src/auth.py", "src/models.py"],
    model="pro",
    timeout_seconds=180
)

提示: 扫描大型树结构时,切换到 mode="at_command",以便 Gemini CLI 原生处理文件通配符和截断。

使用网页搜索上下文向 Gemini 提问。当模型确定需要时,使用 Gemini CLI 的自动网页搜索。尽力而为的功能 - 不保证每次查询都有效。

参数:

  • query (string):要在网页上查找的搜索查询或问题

  • directory (string):命令执行的工作目录

  • model (string, 可选):使用的模型 - "flash", "pro", "flash-lite", "2.5-lite", "3-pro", "3-flash", "3.1-pro", "3.1-flash-lite", 或 "auto" (默认: "flash")

  • timeout_seconds (int, 可选):覆盖此请求的执行超时时间

示例:

web_search(
    query="latest Python version and new features",
    model="flash"
)

📋 使用示例

基础代码分析

# Simple research query
consult_gemini(
    query="What authentication patterns are used in this project?",
    directory="/Users/dev/my-project"
)

详细文件审查

# Analyze specific files
consult_gemini_with_files(
    query="Review these files and suggest security improvements",
    directory="/Users/dev/my-project",
    files=["src/auth.py", "src/middleware.py"],
    model="pro"
)

多文件分析

# Compare multiple implementation files
consult_gemini_with_files(
    query="Compare these database implementations and recommend the best approach",
    directory="/Users/dev/my-project",
    files=["src/db/postgres.py", "src/db/sqlite.py", "src/db/redis.py"],
    mode="at_command"
)

网页搜索

# Get current information from the web
web_search(
    query="latest Python version and new features in 3.13",
    model="flash"
)

大文件保护措施

  • 内联传输限制为每个文件约 256 KB,每个请求约 512 KB,以避免挂起。

  • 超大文件会被截断为头部/尾部片段,并在 MCP 响应中发出警告。

  • 使用环境变量(GEMINI_BRIDGE_MAX_INLINE_TOTAL_BYTES 等)调整上限,或对于更大的负载优先使用 mode="at_command"。

🏗️ 架构

核心设计

  • CLI 优先:直接对 gemini 命令进行子进程调用

  • 无状态:每个工具调用都是独立的,没有会话状态

  • 自适应超时:默认为 60 秒,但可按请求或通过环境变量覆盖

  • 附件护栏:内联模式强制执行轻量级限制;@ 模式委托给 Gemini CLI 工具

  • 简单的错误处理:清晰的错误消息,采用快速失败方法

TDQS

A4.1/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description discloses that the query is 'forwarded verbatim to the CLI', explains optional parameters (model, timeout), and describes the return value as 'Gemini's response text or an explanatory error string'. This provides sufficient behavioral context for a query tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with Args/Returns sections and no extraneous content. It is concise but includes necessary parameter details. Minor tightening could improve it, but overall effective.

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 tool's moderate complexity (4 params, 2 required) and presence of an output schema (implied by return description), the description covers the key behavioral aspects. It explains inputs, optional overrides, and return value, making it complete enough for effective use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 0% description coverage, so the description carries the burden. It explains all four parameters: query (prompt text), directory (working directory), model (optional alias or ID), timeout_seconds (per-call override). This adds meaning beyond the schema's raw type definitions.

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 'Send a query directly to the Gemini CLI', specifying the verb (send) and resource (Gemini CLI). The name 'consult_gemini' and sibling tools 'consult_gemini_with_files' and 'web_search' help distinguish its purpose as a direct query without file context.

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 mention when to use this tool vs. 'consult_gemini_with_files' or 'web_search'. It only implies usage for direct queries without files, lacking alternative guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

consult_gemini_with_filesA

Send a query to the Gemini CLI with file context.

Args:
    query: Prompt text forwarded to the CLI.
    directory: Working directory used for resolving relative file paths.
    files: File paths to include alongside the prompt. Paths must resolve
        inside ``directory``; entries pointing outside it are skipped.
    model: Optional model alias (``flash``, ``pro``) or full Gemini model id.
    timeout_seconds: Optional per-call timeout override in seconds.
    mode: ``"inline"`` streams truncated snippets; ``"at_command"`` emits
        ``@path`` directives so Gemini CLI resolves files itself.

Returns:
    Gemini's response or an explanatory error string with any warnings.

TDQS

A4/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden and does well: it discloses that files outside the working directory are silently skipped, that errors are returned as explanatory strings with warnings, and that per-call timeouts are possible. It stops short of stating auth/network prerequisites or what triggers truncation limits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded one-line summary followed by structured Args/Returns sections; each parameter line earns its place. The Returns block partially duplicates the output schema but is short enough not to be wasteful.

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?

For a 6-parameter external-CLI tool, all parameters and the path-safety rule are covered, and an output schema exists so return values need little prose. The main gap is the absent routing guidance versus consult_gemini and no discussion of limits when many/large files are passed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the schema even lacks enum metadata, so the description must compensate fully — and it does, defining mode values ('inline' streams truncated snippets vs 'at_command' emits @path directives), model aliases (flash/pro), the path-resolution constraint on files, and the purpose of directory and timeout overrides.

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?

States a specific verb and resource ('Send a query to the Gemini CLI with file context'), which clearly separates it from the sibling consult_gemini that lacks file context. It is clear, but it never explicitly contrasts itself with that sibling or names when file context is needed.

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 when-to-use/when-not guidance or named alternative is given; the agent must infer from the tool name that files-bearing queries belong here rather than in consult_gemini. The mode explanation implies usage patterns but does not state selection criteria.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS

A4.1/5.0

Scored across 3 tools

Disambiguation4/5

The three tools are mostly distinguishable: consult_gemini is plain, consult_gemini_with_files adds file context, and web_search adds search context. The overlap between the two consult_* tools is real—they differ only by file arguments—but the file/web/plain split gives an agent a reasonable basis for selection.

Naming Consistency4/5

Two tools follow a clean consult_gemini / consult_gemini_with_files pattern, and web_search is a readable verb_noun name. The only deviation is web_search not carrying the consult_ prefix, but it describes a genuinely different capability so it still reads consistently.

Tool Count4/5

Three tools is well-scoped for a thin bridge to a single CLI. Each tool maps to a distinct query mode rather than padding the surface, though the small count sits at the lower edge of the ideal range.

Completeness4/5

For a Gemini CLI passthrough the surface covers the main workflows: plain queries, file-context queries, and web-grounded queries. Minor gaps exist (no streaming/session continuity or config/inspection tool), but agents can accomplish the core task set without dead ends.
