Full call logging
Every tool call is logged with complete inputs and outputs, so you can debug issues and audit what your agents are doing.
Tool access control
Enable or disable individual tools per connector, so you decide what your agents can and cannot do.
Managed credentials
Glama handles OAuth flows, token storage, and automatic rotation, so credentials never expire on your clients.
Usage analytics
See which tools your agents call, how often, and when, so you can understand usage patterns and catch anomalies.
Tool Definition Quality
Average 4.2/5 across 1 of 1 tools scored.
With only one tool, there is no possibility of confusion or overlap between tools. The purpose is singular and unambiguous.
The sole tool name 'screen_entity' follows a clear verb_noun pattern. While there are no other tools to compare, the naming is consistent with common conventions.
A single tool feels thin even for a focused purpose—potential helper functions like listing sanctioned lists or status checks are absent. However, the scope is clear and the tool is fully featured for its stated function.
The screening workflow is covered end-to-end with a single call, including multiple lists and a report URL. Minor gaps like batch processing or list customization do not hinder core usability.
Available Tools
1 toolscreen_entitySanctions screening (OFAC SDN + 7 more lists)ARead-onlyIdempotentInspect
Screen a person or entity name against 8 global sanctions lists: OFAC SDN, OFAC Non-SDN (Consolidated), BIS Denied Persons List, UN Security Council Consolidated List, EU Financial Sanctions File, UK OFSI Consolidated List, Canada SEMA, and Swiss SECO. Uses fuzzy name matching and returns scored matches with aliases and addresses. Free to use, no account required. Results include a report_url where an audit-ready PDF of the screening can be obtained.
| Name | Required | Description | Default |
|---|---|---|---|
| name | Yes | Full name of the person or entity to screen, e.g. "Vladimir Petrov" or "Acme Trading LLC". | |
| entity_type | No | Optional filter: restrict matches to individuals or to entities/organizations. Omit to search both. |

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the annotations that declare readOnly/idempotent/non-destructive, the description adds that it 'Uses fuzzy name matching and returns scored matches with aliases and addresses,' and that results include a 'report_url' for an audit-ready PDF. This provides useful context on how the tool behaves and what it returns, though it doesn't detail failure modes or error handling.
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 compact and front-loads the primary action, followed by key behavioral details and a note on accessibility. The enumerating of 8 list names is detailed but relevant; no sentence is wasted.
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 has a clear scope, and the presence of an output schema covers return value details, so the description doesn't need to enumerate them. It covers the main behavioral aspects (fuzzy matching, scored results, report_url) and access conditions (free, no account), making it reasonably complete for an agent to select and invoke correctly.
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?
The input schema already fully describes both parameters (name and entity_type) with 100% coverage, so the description doesn't need to repeat them. It does add a note about fuzzy matching that affects how the name parameter is interpreted, but otherwise it doesn't provide significant additional semantic meaning beyond the schema.
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 the specific verb 'Screen' and specifies the resource ('a person or entity name') against 8 named global sanctions lists, clearly distinguishing it from any generic search or lookup. It enumerates the exact lists, leaving no ambiguity about the tool's scope.
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 implicitly conveys when to use this tool (for sanctions screening) and notes 'Free to use, no account required,' suggesting accessibility. However, there are no explicit exclusion criteria or alternative tools named, and the absence of sibling tools means differentiation is not needed, but the guidance is clear enough.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
