execute_hub_tool

Execute a security tool from the hub using its identifier. Supports arguments, timeout, and file access via mounted directories; outputs are saved to a persistent volume.

Instructions

Execute a tool from a hub server.

:param identifier: Tool identifier (format: hub:server:tool or server:tool). :param arguments: Tool arguments matching the tool's input schema. :param timeout: Optional execution timeout in seconds. :return: Tool execution result.

Example identifiers:

  • "hub:binwalk-mcp:binwalk_scan"

  • "hub:yara-mcp:yara_scan_with_rules"

  • "hub:nmap:nmap_scan"

FILE ACCESS — if set_project_assets was called, the assets directory is mounted read-only inside the container at two standard paths:

  • /app/uploads/ (used by binwalk, and tools with UPLOAD_DIR)

  • /app/samples/ (used by yara, capa, and tools with SAMPLES_DIR) Always use /app/uploads/ or /app/samples/ when passing file paths to hub tools — do NOT use the host path.

Tool outputs are persisted to a writable shared volume:

  • /app/output/ (writable — extraction results, reports, etc.) Files written here survive container destruction and are available to subsequent tool calls. The host path is .secpipe/output/.

Behavior4/5

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

Without annotations, the description covers key behaviors: read-only file mounts for assets, persistent writable output directory, and optional timeout. It does not discuss destructiveness or authentication, but for an execution tool this is adequate.

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 front-loaded with the main purpose and then provides necessary detail on file paths. It is slightly lengthy but earns its sentences.

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 complexity (file mounts, output persistence, identifier format), the description is fairly complete. Output schema exists, so return values are covered elsewhere.

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?

Schema coverage is 0%, but the description adds meaning: identifier format with examples, arguments matching input schema, and timeout as optional seconds. This compensates well.

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 explicitly states 'Execute a tool from a hub server,' with example identifiers that clarify the format. It clearly distinguishes from sibling tools that list or discover tools.

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?

The description provides clear guidance on when to use (execute a tool) and includes example identifiers. It also explains file access and output paths, though it does not explicitly mention alternatives like continuous execution.

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