- Cryptographically verified build provenance (signed, bound to atriumn/tokencost-dev). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 205 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability83
- AI-judged instruction clarity (excellent).Pass

- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management90
- Stability observed for 27 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
calculate_estimate ~112
Estimate the cost for a given number of input and output tokens on a specific model. Supports optional cached_tokens for prompt caching discounts.
| Name | Type | Req | Description |
|---|---|---|---|
| cached_tokens | number | – | Number of input tokens served from cache (prompt caching). Must be <= input_tokens. These tokens are billed at the cached rate instead of the standard input rate. |
| input_tokens | number | yes | Number of input tokens |
| model_name | string | yes | Model name (fuzzy matched) |
| output_tokens | number | yes | Number of output tokens |
No output schema declared.
No examples provided.
compare_models ~98
Filter and compare models by provider, minimum context window, or mode. Returns top 5 most cost-effective matches.
| Name | Type | Req | Description |
|---|---|---|---|
| min_context | number | – | Minimum context window size in tokens |
| mode | string | – | Filter by mode (e.g. 'chat', 'embedding', 'completion', 'image_generation') |
| provider | string | – | Filter by provider (e.g. 'anthropic', 'openai', 'google', 'amazon') |
No output schema declared.
No examples provided.
get_model_details ~79
Look up pricing, context window, and capabilities for an LLM model. Uses fuzzy matching so you don't need the exact model key.
| Name | Type | Req | Description |
|---|---|---|---|
| model_name | string | yes | Model name to look up (e.g. 'claude-sonnet-4-5', 'gpt-4o', 'gemini-2.0-flash') |
No output schema declared.
No examples provided.
refresh_prices ~33
Force a re-fetch of pricing data from the LiteLLM registry. Use this if you suspect the cached data is stale.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
