flux7-mesh 0.3.0

Python SDK for flux7-mesh — governance mesh for AI agent tool calls

mesh7 Python SDK

Governance mesh for AI agent tool calls. Wraps any Python function with policy enforcement, human approval, and tracing via flux7-mesh.

Install

pip install flux7-mesh
pip install flux7-mesh[anthropic]  # with Claude API support

Quick start

Direct client

from mesh7 import AgentMesh

mesh = AgentMesh("http://localhost:9090", agent="my-agent")

# Check what's available
tools = mesh.tools()
health = mesh.health()

# Policy check only (POST /decide) — no execution
decision = mesh.decide("filesystem.write_file", {"path": "/tmp/x"})
print(decision.action)  # allow | deny | human_approval

# Full proxy (POST /tool/{name}) — policy + execute + trace
decision = mesh.call_tool("filesystem.read_file", {"path": "/tmp/data.txt"})
print(decision.result)

# Manage grants
mesh.create_grant("filesystem.*", "30m")
mesh.revoke_grant("grant-id")

GovernedToolkit (Claude API)

from mesh7 import GovernedToolkit

toolkit = GovernedToolkit(agent="my-agent")

@toolkit.tool
def get_weather(city: str) -> str:
    """Get current weather for a city."""
    return fetch_weather(city)

@toolkit.tool
def send_email(to: str, subject: str, body: str) -> str:
    """Send an email."""
    return smtp_send(to, subject, body)

# Generate tools[] for Claude API
schemas = toolkit.schemas()

# Process tool_use blocks with governance
response = client.messages.create(model="claude-sonnet-4-6", tools=schemas, ...)
results = toolkit.process_response([b.model_dump() for b in response.content])

The toolkit:

1. schemas() — generates the tools[] array from Python function signatures
2. process_response() — intercepts tool_use blocks, checks policy via mesh7, executes locally if allowed
3. execute() — single tool call with governance

Prerequisites

mesh7 daemon running:

mesh7 serve --config config.yaml
