# BenchLM: 10 WebMCP tools for AI agents

![](https://www.google.com/s2/favicons?domain=benchlm.ai&sz=96)

AI & agents · benchlm.ai

## BenchLM

LLM leaderboard and benchmark site. Agents can find, compare and recommend models, look up benchmark results and estimate cost.

[Open benchlm.ai](https://benchlm.ai/)

## Ask an agent to

-   Find the best models for coding
-   Compare two AI models side by side
-   Estimate monthly API cost for 10,000 blog posts

## 10 tools

When we loaded benchlm.ai again on Oct 24, 2026, it registered these through `navigator.modelContext` or `provideContext()`, from earlier WebMCP drafts. Chrome 154 only offers `document.modelContext`, so Chrome’s own agent support does not see them.

-   `compare_ai_models`
    
    Return a BenchLM side-by-side comparison summary for two AI models, then open the comparison page in the current tab. Use this when a user wants benchmark, pricing, context window, or capability tradeoffs between…
    
    modelA: string, modelB: string
    
-   `estimate_ai_cost`read-only
    
    Estimate monthly, daily, and yearly AI model cost for real workloads such as blog posts, website pages, docs articles, PRDs/specs, or shipped product features.
    
    workload: string, unitsPerMonth: number?, wordsPerUnit: number?, revisionRounds: number?, complexity: string?, modelNames: array?
    
-   `find_best_models`read-only
    
    Return top BenchLM-ranked AI models for a use case such as coding, reasoning, tool use, web research, computer use, long context, document AI, image understanding, factuality, open source, or value.
    
    useCase: string, limit: number?, openWeight: boolean?, maxOutputPrice: number?, minContextTokens: number?, reasoning: boolean?
    
-   `get_model_details`read-only
    
    Return BenchLM metadata for one AI model, including provider, score, source type, context window, reasoning mode, pricing, speed, and category scores.
    
    model: string
    
-   `lookup_benchmark_results`read-only
    
    Return the BenchLM leaderboard for a specific benchmark, such as SWE-bench Verified, LiveCodeBench, MMLU, GPQA, BFCL, BrowseComp, OSWorld, or AIME.
    
    benchmark: string, limit: number?, includeUnverified: boolean?
    
-   `open_benchlm_page`
    
    Navigate the current BenchLM tab to the best matching page for a model, benchmark, provider, ranking, comparison, blog post, or tool query.
    
    query: string, type: string?
    
-   `open_model_profile`
    
    Navigate to the BenchLM profile page for a specific AI model by model name, alias, or slug.
    
    model: string
    
-   `recommend_llm`read-only
    
    Recommend AI models using BenchLM selector logic for a user use case, budget, context-window need, open-weight preference, and speed/quality preference.
    
    useCase: string, task: string?, audience: string?, budget: string?, context: string?, openWeight: string?, speed: string?, limit: number?
    
-   `search_benchlm`read-only
    
    Search BenchLM for AI models, benchmarks, rankings, comparisons, tools, providers, and blog posts. Use this before navigating when the exact BenchLM page is unknown.
    
    query: string, limit: number?
    
-   `subscribe_to_benchlm_updates`
    
    Subscribe an email address to weekly BenchLM benchmark, ranking, and pricing updates. This tool always asks the user to confirm before submitting.
    
    email: string

Tool names and descriptions are what benchlm.ai/ registered when we loaded it in Chrome 154 on Browser Use Cloud. The summary and the “ask an agent” lines are AI-written from them. To call the tools yourself, see [Chrome’s WebMCP docs](https://developer.chrome.com/docs/ai/webmcp). [How we found it](https://browser-use.com/webmcp#method).
