Tenable Identity Exposure MCP Server

tie_attacks

List Indicator of Attack (IoA) instances for a resource within a security profile. Filter by attack type, date range, or search to identify and investigate threats.

Instructions

List IoA attack instances for a resource within a profile.

The TIE API requires scoping attacks to a resource. For example, to see attacks against directory id 8: resource_type="directory", resource_value="8".

Args: resource_type: What resource_value refers to — infrastructure, directory, hostname, or ip. resource_value: The id (for infrastructure/directory) or name/ip value to scope to. profile_id: Security profile id (default 1). attack_type_ids: Optional list of attack type ids to filter (e.g. DCSync, Kerberoasting). date_start: Optional ISO 8601 start of date range. date_end: Optional ISO 8601 end of date range. include_closed: Include closed attacks (default False). limit: Max results (default 50). order: Sort order by date, "desc" (newest first) or "asc". search: Optional free-text search filter.

Behavior2/5

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

No annotations are provided, and the description does not explicitly state whether the operation is read-only, destructive, or has side effects. 'List' implies read-only, but this is not confirmed.

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 a brief summary, an example, and a parameter list. It is concise but could be slightly more streamlined without the example.

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 tool with 10 parameters and no output schema, the description covers parameter semantics thoroughly. It lacks details on return format or pagination, but the purpose is well-defined.

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?

Despite 0% schema description coverage, the description provides detailed explanations for all 10 parameters, including types, defaults, and usage context, adding significant value beyond the schema.

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 the tool lists IoA attack instances for a resource within a profile, with a specific verb and resource. It distinguishes from sibling tools which cover alerts, catalog, deviances, etc.

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 explains that scoping to a resource is required and provides an example. It does not explicitly mention when not to use or alternatives, but the context is clear for a resource-specific list tool.

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