TokenOps control plane and SDK for run-aware agent token governance

TokenOps

Run-aware token governance for multi-agent systems.
Cap spend and steer behavior across a whole agent workflow — not per request — with a shared ledger and in-path enforcement.

TokenOps is a control plane + SDK for agent stacks. Entry agents register a run; every LLM and tool crossing shares one run_id and one ledger. Policies can halt, mutate, or inject before the next call executes — so a research → summarize → review pipeline stays inside a single budget even across processes.

Why TokenOps

• Govern the run, not the request. One run_id spans every model, tool, and A2A hop in a workflow.
• Shared ledger across processes. Spend, inflight, and halt live in SQLite so multi-agent stacks cannot each burn the full cap locally.
• In-path enforcement. wrap_complete runs detect → decide → apply before the next LLM call; Chronicle @boundary + a crossing hook ingest tool spend.
• Steer or stop. Actuators: HALT · MUTATE · INJECT · reject/queue — not just post-hoc analytics.
• Batteries included. Control plane (:7700), Admin + Dashboard UI, ten seeded policies, and runnable A2A benches (two-agent, triad, LangChain brief).

Architecture

TokenOps is two layers that share one artifact, the run: a control plane that registers runs and stores budgets/policies, and an in-process SDK that enforces at every boundary crossing.

Piece	Owns	Does not own
Control plane (python -m tokenops.server)	POST /v1/runs, shared SQLite, Admin/Dashboard	Agent loops, LLM calls, tools
SDK (in agents)	wrap_complete, ledger/policies, Chronicle crossing hook, run propagation	Ad-hoc run IDs; mounting /v1/runs when TOKENOPS_URL is set

Chronicle records decision boundaries; TokenOps attaches as the cost/governance observer on live crossings. See Chronicle for record-and-replay.

Install

pip install agent-tokenops

# With example / bench extras (LangChain, ddgs):
pip install "agent-tokenops[examples]"

# From source (development):
pip install -e ".[dev,examples]"

Requires Python 3.10+. PyPI name is agent-tokenops; import is still tokenops (same pattern as Chronicle). See RELEASING.md for releases.

Quick start

make install
cp .env.example .env   # optional API keys for demos / your agents

make db-reset          # optional: clean SQLite + seed governance from default.yaml
make run               # control plane :7700 + Admin/Dashboard :8501

Wire governance into an agent: register the run at the entry, wrap the LLM, and install the Chronicle crossing hook for tools.

from tokenops import ControlPlaneClient
from tokenops.control import (
    wrap_complete,
    entry_task_run_scope,
    governance_scope,
    install_crossing_hook,
)
from tokenops.providers import complete

install_crossing_hook()  # once per process; Chronicle on_crossing → Governor.observe

client = ControlPlaneClient.from_env()  # TOKENOPS_URL or embedded Store

# Entry agent: UI omits run_id; entry opens the run on the plane
with entry_task_run_scope(store, headers=headers, payload=payload, service="planner"):
    with governance_scope(governor, attr, provider=..., model=...):
        governed = wrap_complete(
            governor, controls, attr,
            provider=provider, model=model,
            dispatch=complete, service="planner",
        )
        run_agent(..., complete_fn=governed)

Point agents at the plane and share one DB:

export TOKENOPS_URL=http://localhost:7700
export TOKENOPS_DB=tokenops.db   # plane + all agents
make control-plane               # :7700
make ui                          # Admin + Dashboard :8501

Demos

Each bench is a multi-agent stack with a shared run ledger. Start the plane, agents, and Admin UI with one make target.

Demo	Agents	Run
Two-agent	Research → Summarize	make demo
Triad	Planner → Researcher → Writer	make demo-triad
Brief	Scout → Analyst → Editor (LangChain)	make demo-brief
Bench UI	Chat + Simulator only	make bench-ui

make demo              # plane + research/summarize + Admin UI
make demo-triad        # plane + planner/researcher/writer
make demo-brief        # plane + scout/analyst/editor

Docker:

docker compose up --build
# optional UI: docker compose --profile ui up --build
# two-agent stack:
docker compose -f docker-compose.examples.yml up --build

See examples/README.md and docs/control-plane-deploy.md.

How TokenOps compares

TokenOps is not a gateway or a tracing dashboard. It governs the run — a full agent workflow — and sits alongside the tools you already use for routing and observability.

	TokenOps	LiteLLM / Portkey / AI Gateway	Langfuse
Primary focus	Run (stateful)	Request	Trace (observe)
Multi-agent workflow as one unit	Yes	No	Manual stitch
Budget enforcement in-path	Yes (run-aware)	Yes (key/team)	No (analytics)
Steer next call (mutate / inject)	Yes	Routing / fallbacks	No
Shared ledger across agent processes	Yes	N/A	N/A

What this does not do: replace your LLM gateway, replace Chronicle-style record-and-replay, or host a SaaS control plane for you. Fail-closed integrity (refuse on missing registration) is optional and upcoming.

Make targets

Command reference

Target	Role
make install	Editable install with dev + examples extras
make dist / check-dist	Build sdist+wheel / twine check
make control-plane	Standalone plane (python -m tokenops.server) on :7700
make ui	Admin + Dashboard on :8501
make run	Plane + Admin/Dashboard
make demo / demo-triad / demo-brief	Runnable A2A stacks
make bench-ui	Chat + Simulator
make db-reset	Clear SQLite + reseed from TOKENOPS_CONFIG
make stop	Kill listeners on :7700 / :8501

Environment variables

Variable	Purpose
TOKENOPS_URL	Remote plane base URL (e.g. http://localhost:7700) → HTTP register_run
TOKENOPS_EMBEDDED	Set to 1 to force in-process Store (tests / single-process)
TOKENOPS_DB	SQLite path shared by plane + agents
TOKENOPS_CONFIG	YAML for governance seed (core: src/tokenops/config/default.yaml)

Production / multi-process: set TOKENOPS_URL; agents must not mount /v1/runs. Tests: TOKENOPS_EMBEDDED=1 (or omit URL).

Roadmap

TokenOps is early (0.x). Near-term:

• User/tag segment-scoped budgets (machinery exists; seed is run-only today).
• Optional fail-closed mode on missing registration or exceeded budget.
• Remote observe / decide (fatter plane) for multi-host stacks.
• Documentation site.

Status of each control-plane job: CONTROL_PLANE.md. Ideas welcome via GitHub issues.

Documentation

• Control plane status
• Architecture
• Run attribution
• Control plane deploy
• Field guide
• Examples
• Product: comparison · shared ledger

Contributing

Issues and PRs are welcome. Dev setup:

make install
