What is or-find-tool-models?

A workflow for finding OpenRouter models that support tool use, also called function calling. This lets an AI model request actions from software tools, such as APIs or agent services.

Use it to find models for coding agents, MCP workflows, and other applications that need function calling. It can narrow results to a provider or sort them by cost or context.

It filters out models that do not declare this capability and can rank the rest by price, context size, or provider. That makes it easier to choose models for tool-using agents.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00073	$0.00480
Opus 5.5	$0.00029	$0.00192

Security

Grade A, and why

or-find-tool-models scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

What it actually says

Find OpenRouter Tool-Calling Models

Filter the OpenRouter catalog to models that declare tool/function calling support, then rank or summarize them based on the user's stated criteria (price, context, provider).

When to use

The user wants to discover models suitable for agentic / tool-using workflows on OpenRouter — function calling, MCP, code agents, structured tool invocation.

Workflow

Fetch the catalog:

curl -s https://openrouter.ai/api/v1/models -H "Accept: application/json"

Filter data[] where supported_parameters includes "tools". Optionally also require "tool_choice" for stricter filtering.
If the user expressed preferences (cheapest, largest context, specific provider), apply them:
- Cheapest — sort by pricing.completion ascending
- Largest context — sort by context_length descending
- Provider — filter id by prefix (openai/, anthropic/, google/, meta-llama/, etc.)
If the user did not state criteria, ask one short clarifying question: budget ceiling? minimum context? preferred providers?
Return the top 5–10 matches as a markdown table: ID, Context, Prompt $/1M, Completion $/1M, Other supported params.

Notes

Prices in the catalog are USD per token. Multiply by 1,000,000 for $/1M-token display.
Some models list tools but have caveats noted in their description — surface those if relevant.
Free models (pricing all "0") often have rate limits and lower reliability — flag this when recommending free models.

Output

Markdown table sorted by the user's stated criterion (default: cheapest completion price). Include a one-line summary of how many tool-capable models exist in the catalog total.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
