axiorank 0.5.0

Official Python SDK for AxioRank - route AI agent tool calls through your agent firewall.

axiorank

Official Python SDK for AxioRank - route your AI agent's tool calls through your agent firewall so policies are enforced, risk is scored, and every call is audited.

Parity with the TypeScript @axiorank/sdk.

Install

pip install axiorank

Quickstart (sync)

import os
from axiorank import AxioRank

axio = AxioRank(api_key=os.environ["AXIORANK_API_KEY"])  # looks like axr_live_...

# Get the decision and act on it yourself:
result = axio.tool_call("github.push", {"repo": "myrepo"})
if result.decision == "deny":
    print(f"Blocked: {result.reason} (risk {result.risk})")
else:
    ...  # proceed with the real tool call

enforce() - guard in one line

from axiorank import AxioRank, AxioRankDeniedError

axio = AxioRank(api_key=os.environ["AXIORANK_API_KEY"])

try:
    axio.enforce("aws.delete_bucket", {"name": "prod-data"})
    delete_bucket("prod-data")  # only runs if AxioRank allowed it
except AxioRankDeniedError as e:
    log.warning("AxioRank blocked the call: %s", e.result.reason)

A require_approval policy holds the call for a human; tool_call/enforce transparently wait out the hold and resolve to the final allow/deny.

Quickstart (async)

import os
from axiorank import AsyncAxioRank

async def main():
    async with AsyncAxioRank(api_key=os.environ["AXIORANK_API_KEY"]) as axio:
        result = await axio.tool_call("stripe.refund", {"amount": 5000})
        print(result.decision, result.risk)

Preflight an external server before trusting it

result = axio.verify_card(url="https://mcp.acme.com")
print(result.decision, result.identity.signature_valid, result.protocol)

# Or guard in one line - raises AxioRankCardDeniedError on `deny`:
axio.enforce_card(url="https://mcp.acme.com")

LangChain

pip install "axiorank[langchain]"

from axiorank import AxioRank
from axiorank.integrations.langchain import AxioRankCallbackHandler

axio = AxioRank(api_key=os.environ["AXIORANK_API_KEY"])

# Every tool the agent runs is checked against your policies first; a blocked
# tool raises and the step fails.
agent_executor.invoke(
    {"input": "..."},
    config={"callbacks": [AxioRankCallbackHandler(axio)]},
)

Prefer a model-readable refusal over a raised exception? Wrap individual tools:

from axiorank.integrations.langchain import guard_tool

safe_tool = guard_tool(my_tool, axio, on_deny="return")

LlamaIndex

pip install "axiorank[llamaindex]"

from axiorank.integrations.llamaindex import guard_tool

# Wrap any FunctionTool - its arguments are scored before it runs, and the
# schema, name, and description are preserved, so it is a drop-in replacement.
safe_tool = guard_tool(my_tool, axio)                      # raises on deny
recoverable = guard_tool(my_tool, axio, on_deny="return")  # model-readable refusal

Pydantic AI

pip install "axiorank[pydantic-ai]"

from axiorank.integrations.pydantic_ai import guard_tool

# Wrap a Tool; its name, description, and signature (schema) are preserved.
safe_tool = guard_tool(my_tool, axio)                       # sync tool
safe_async = guard_tool(my_tool, async_client=axio_async)   # async tool

OpenAI Agents (Python)

pip install "axiorank[openai-agents]"

from axiorank import AsyncAxioRank
from axiorank.integrations.openai_agents import guard_tool

axio = AsyncAxioRank(api_key=os.environ["AXIORANK_API_KEY"])

# The SDK runs tools async; a deny returns a refusal the model can re-plan around.
safe_tool = guard_tool(my_function_tool, axio, on_deny="return")
