Tool Configuration Guide

Overview

Each tool ships with its own YAML configuration placed in the tools/ directory. This keeps definitions modular, easier to review, and simple to extend. The runtime automatically loads every .yaml / .yml file in that directory.

File Structure

The table below enumerates every supported top-level field. Double-check each entry before adding a new tool:

Field	Required	Type	Description
name	✅	string	Unique identifier. Prefer lowercase letters, digits, and hyphens.
command	✅	string	Executable or script name. Must exist in $PATH or be an absolute path.
enabled	✅	bool	Controls MCP registration. Disabled tools are ignored by the loader.
description	✅	string	Full Markdown description for MCP resources/read and AI comprehension.
short_description	Optional	string	20–50 character summary shown in tool lists. When omitted, the loader extracts the start of description.
args	Optional	string[]	Static arguments prepended to every invocation—useful for default scan profiles.
parameters	Optional	array	Runtime parameter definitions. See Parameter Definition for details.
arg_mapping	Optional	string	Mapping strategy (auto/manual/template). Defaults to auto; override only for legacy tooling.

If a required field is missing or malformed, the loader skips that tool and logs a warning without blocking the service.

Tool Descriptions

Short Description (short_description)

• Purpose: compact summary for tool listings and to minimise language model context usage.
• Guideline: one concise sentence (20–50 Chinese characters or English equivalents).
• Example: "Network scanner for discovering hosts, open ports, and services"

Detailed Description (description)

Supports multi-line Markdown. Recommended contents:

1. Capabilities – what the tool does.
2. Usage scenarios – when to prefer this tool.
3. Warnings – permissions, runtime risks, side-effects.
4. Examples – optional walkthroughs or sample commands.

Important:

• Tool menus and MCP summaries use short_description when available.
• Without short_description, the loader trims the first line or first 100 characters of description.
• Full descriptions are accessible through the MCP resources/read endpoint (tool://<tool_name>).

Parameter Definition

Each parameter object accepts the fields below:

• name (required) – parameter key used in CLI construction and MCP schema.
• type (required) – string, int/integer, bool/boolean, array, etc.
• description (required) – Markdown-friendly explanation including purpose, format rules, example values, and safety notes.
• required – boolean; when true, missing values cause the executor to return an error.
• default – fallback value applied if the caller omits the argument.
• flag – CLI switch such as -u or --url.
• position – zero-based index for positional arguments.
• format – rendering strategy:
  • flag (default) → --flag value / -f value
  • combined → --flag=value
  • positional → appended according to position
  • template → uses the template string
• template – placeholder string (supports {flag}, {value}, {name}) when format: "template".
• options – array of allowed values; surfaced as enum entries in the MCP schema.

Format Reference

• flag: pass the flag and the value separately.
  Example: flag: "-u" → -u https://example.com

• positional: insert according to position.
  Example: position: 0 → becomes the first positional argument.

• combined: join flag and value in one token.
  Example: flag: "--level", format: "combined" → --level=3

• template: custom rendering.
  Example: template: "{flag} {value}" → fully manual control.

Reserved Parameters

• additional_args – allows users to append arbitrary CLI fragments. The executor tokenises the string (preserving quoted groups) and appends the resulting list to the command.
• scan_type – for scanners like nmap, replacing default scan switches (e.g., -sV -sC).
• action – consumed by server-side branching logic and intentionally not forwarded to the command line.

Parameter Description Checklist

When documenting a parameter, include:

1. Purpose – what the value controls.
2. Format rules – accepted patterns (URL, CIDR, path, etc.).
3. Example values – list several realistic samples.
4. Notes – permissions, performance impact, or other caveats.

Suggested style: Markdown lists, bold emphasis for key cautions, and code blocks for complex examples.

Example

description: |
  Target IP address or domain. Accepts single IPs, ranges, CIDR blocks, or hostnames.

  **Example values**
  - Single IP: "192.168.1.1"
  - Range: "192.168.1.1-100"
  - CIDR: "192.168.1.0/24"
  - Domain: "example.com"

  **Notes**
  - Required; cannot be empty.
  - Validate address format before running to avoid false positives.

Parameter Types

Boolean

• true → adds only the flag (no value).
• false → suppresses the flag.
• Accepts true/false, 1/0, and "true"/"false".

- name: "verbose"
  type: "bool"
  description: "Enable verbose output"
  required: false
  default: false
  flag: "-v"
  format: "flag"

String

Most common parameter type; accepts any string value.

Integer

Use for numeric inputs (ports, levels, limits).

- name: "level"
  type: "int"
  description: "Level of detail, 1-5"
  required: false
  default: 3
  flag: "--level"
  format: "combined"  # --level=3

Array

Automatically converted to a comma-separated string.

- name: "ports"
  type: "array"
  description: "List of ports to scan"
  required: false
  # Input: [80, 443, 8080]
  # Output: "80,443,8080"

Special Parameters

additional_args

- name: "additional_args"
  type: "string"
  description: "Extra CLI arguments; separate multiple options with spaces"
  required: false
  format: "positional"

Examples:

• additional_args: "--script vuln -O" → ["--script", "vuln", "-O"]
• additional_args: "-T4 --max-retries 3" → ["-T4", "--max-retries", "3"]

Notes:

• Quoted strings are preserved.
• Validate user input to avoid command injection.
• Appended at the end of the final command.

scan_type

- name: "scan_type"
  type: "string"
  description: "Overrides default scan switches"
  required: false
  format: "positional"

Examples:

• scan_type: "-sV -sC"

Adding a New Tool

1. Create a YAML file in tools/ (e.g., tools/mytool.yaml).
2. Fill out the top-level fields and parameter list.
3. Provide defaults and rich descriptions wherever possible.
4. Run go run cmd/test-config/main.go to validate the configuration.
5. Restart the service (or trigger a reload) so the UI and MCP registry pick up the change.

Template

name: "tool_name"
command: "command"
enabled: true

short_description: "One-line summary"

description: |
  Detailed description with Markdown formatting.

parameters:
  - name: "target"
    type: "string"
    description: "Explain the expected value, format, examples, and caveats"
    required: true
    position: 0
    format: "positional"

  - name: "option"
    type: "string"
    description: "Optional flag parameter"
    required: false
    flag: "--option"
    format: "flag"

  - name: "verbose"
    type: "bool"
    description: "Enable verbose mode"
    required: false
    default: false
    flag: "-v"
    format: "flag"

  - name: "additional_args"
    type: "string"
    description: "Extra CLI options separated by spaces"
    required: false
    format: "positional"

Validation & Troubleshooting

• ✅ Verify required fields: name, command, enabled, description.
• ✅ Ensure parameter definitions use supported types and formats.
• ✅ Watch server logs for warnings when a tool fails to load.
• ✅ Use go run cmd/test-config/main.go to inspect parsed tool metadata.

Best Practices

1. Parameter design – expose common flags individually; leverage additional_args for advanced scenarios.
2. Documentation – combine short_description with thorough description to balance brevity and clarity.
3. Defaults – provide sensible default values, especially for frequently used options.
4. Validation prompts – describe expected formats and highlight constraints to help the AI and users avoid mistakes.
5. Safety – warn about privileged commands, destructive actions, or high-impact scans.

Disabling a Tool

Set enabled: false or remove/rename the YAML file. Disabled tools disappear from the UI and MCP inventory.
