Kimss Forge — open-source agent harness

Build and run agents with any model — free, forever. Connect Kimss when production needs governance.

Kimss Forge (kimss-forge on PyPI, import kimss_forge) is a small MIT-licensed harness: a local multi-turn tool loop that talks to any OpenAI-compatible endpoint (OpenAI, Azure/Foundry, Anthropic-compatible proxies, Ollama, vLLM). No Kimss account required to develop and test.

When your security team needs identity, kill switch, budgets, and audit for production, flip one argument — gateway="kimss" — and traffic routes through the Kimss AI Gateway.

from kimss_forge import Agent, tool

@tool
def multiply(a: float, b: float) -> float:
    """Multiply two numbers."""
    return a * b

# Local — your provider key only
agent = Agent(model="gpt-4o-mini", tools=[multiply])
print(agent.run("What is 6 times 7?"))

# Production — one line to the Kimss control plane
agent = Agent(
    model="custom:your-vaulted-model",
    tools=[multiply],
    gateway="kimss",
    agent_id="ops_bot",
    workspace_key="kimss_...",
)

Naming (unified)

Surface	Name
Product	Kimss Forge
GitHub	kimss-ai/kimss-forge
PyPI	`kimss-forge`
Import	`import kimss_forge` / `from kimss_forge import Agent`
Monorepo SSOT	`kimssApi/kimss-forge/`

Why this exists

Layer	Cost	What you get
Forge (this package)	Free / MIT	Run agents, tools, MCP; any model endpoint
Kimss Developer gateway	Free tier (25k governed requests/mo)	Identity, audit trail, kill switch
Kimss Production+	Paid	Authority Boundary, RBAC, Threat Intercepts, PII scrub
Kimss Scale / Enterprise	Paid	SSO, SCIM, retention, schema isolation

Developers adopt Forge to ship faster. CISOs purchase the control plane when production governance is mandatory — without rewriting the agent.

Install

pip install kimss-forge
# optional MCP tools:
pip install 'kimss-forge[mcp]'

Local (zero Kimss)

export OPENAI_API_KEY=sk-...
# optional: OPENAI_BASE_URL=https://your-endpoint/v1
python examples/01_local_agent.py

Production via Kimss (one line)

Sign up at kimss.ai (Developer tier is free).
Vault your provider under Connected Infrastructure.
Mint a kimss_... workspace key.
Set gateway="kimss", agent_id=..., and the workspace key.

Agent(
    model="custom:your-vaulted-model",
    gateway="kimss",          # → https://api.kimss.ai/v1
    agent_id="fleet_reporter",
    workspace_key="kimss_...",
)

Every call sends X-Kimss-Agent-Id. Disable that agent in the Kimss UI and subsequent hops return 403 (kill switch). Paid tiers add Authority Boundary, Team & Access, SCIM/SSO, and more — see pricing.

Examples

Script	What it shows
`examples/01_local_agent.py`	Local chat, no tools
`examples/02_tools.py`	`@tool` functions
`examples/03_mcp.py`	MCP stdio tools (`[mcp]` extra)
`examples/04_production_kimss.py`	Gateway connect

Design decision

See ADR.md (why Forge is separate from the proprietary Hermis server loop, and why kill switch stays free).
