The compliance platform for AI and agent work.

Comma Compliance is the modern communications ingestion layer for regulated organizations. Arc is our platform for capturing, governing, and archiving AI and agent activity alongside the human channels we already cover. Arc Relay is the first piece, available now and open source.

Compliance used to mean email and chat. Now it means agents too.

For two decades, regulated firms have archived email, IMs, and mobile messaging because regulators treat them as business records. Comma Compliance was built for that world - we capture WhatsApp, Signal, iMessage, and 40+ other channels for SEC and FINRA-regulated firms.

AI and agent interactions are the next frontier. Every prompt, every tool call, every autonomous action an agent takes on a regulated user's behalf is becoming a record that needs to be governed, captured, and produced on demand. Comma Compliance Arc is how we extend the ingestion layer to cover that world.

One platform. Human channels and agent channels.

Arc is being built as a set of components that compose into a single compliance fabric for both human and agent activity. Arc Relay is the first piece you can download today. The rest of the platform is rolling out alongside it.

Available now

Arc Relay

Open-source MCP control plane. Sits between AI clients and your MCP servers. Auth, policy, middleware, audit trail, and per-tool access control.

The first piece. The hands-on, MIT-licensed taste of the platform.

Coming next

Compliance MCP servers

Comma's compliance workflow tools - retention, legal hold, discovery, review, export - exposed as MCP servers so an agent can run the full lifecycle.

Compliance becomes an agentic workflow, not a manual one.

Coming

Arc Bridge

Self-hosted integrations for the AI infra you already run - Ollama, vLLM, LiteLLM, Open WebUI, and more. Capture without changing how your team works.

For teams running models behind their own firewall.

Coming

Arc Gate

API proxy for direct LLM provider traffic - OpenAI, Anthropic, Google, and friends. Same middleware pipeline, applied to raw model calls instead of tool calls.

For teams whose agents bypass MCP entirely.

All four components feed into one place:

Encrypted, tamper-evident records, ready for search, legal hold, and export.

The endgame: full lifecycle compliance, whether the work is being done by a human or an agent. Same review, same retention, same audit trail.

Available now - open source

Start with Arc Relay - the first piece of the platform

Arc Relay is the hands-on, open-source taste of what Arc is becoming. Run it today and see the control plane concept in action - per-user access, middleware, audit trail, the works - long before the rest of the platform lands.

Manage every MCP server from one dashboard
Per-server middleware: PII, size, alerting, archive
Per-user, per-tool access control
Connect any MCP client in seconds
Full audit trail of every tool call
Tool-level permissions and usage tracking

How Arc works

1

Capture

Intercept AI activity via MCP control plane, API gateway, enterprise connectors, or self-hosted bridges.

2

Govern

Apply per-user policy, middleware, PII redaction, and access control before anything reaches a model or a tool.

3

Archive

NaCl Box encryption with tenant-isolated keys. Tamper-evident, immutable records with full conversation context.

4

Comply

Search, legal hold, export, and audit trail for regulators. Soon: agents that run the workflow themselves.

Where this is going

Compliance itself is becoming an agentic workflow.

Today, compliance teams click through review queues, set retention rules, and respond to subpoenas by hand. That work is exactly the kind of structured, policy-driven activity that agents are good at - if they have the right tools.

We are building Comma's compliance workflow tools - retention, legal hold, discovery, review, export - as MCP servers. An authorized agent will be able to run the entire lifecycle through the same Arc control plane that captured the records in the first place. Compliance becomes a service the agent can call, not a process the agent gets in the way of.

Regulators are catching up fast

SEC and FINRA enforcement against unarchived business communications has run into the billions. AI conversations and agent tool calls are the next frontier. Every prompt, every response, every autonomous action - if it touches a business decision, it is a record. The firms that build the capture layer now will not be the ones writing the fine cheques later.
