Install Jentic One Beta
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Marrow Agent Governance API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.
Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fgetmarrow.ai%2Fgetmarrow" | shStep 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fgetmarrow.ai%2Fgetmarrow" | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
What an agent can do with Marrow Agent Governance API.
Verify a bound agent's identity and read its health, proof state, and repair guidance
Read tenant-scoped operating context for the agent before it acts
Evaluate a proposed action before execution and return governance guidance
Issue, verify, close, or heartbeat a signed permit for a single governed action
GET STARTED
Close a governed action with its outcome and proof evidence
Read action-permit coverage and the agent's reliability and value metrics
Patterns agents use Marrow Agent Governance API for, with concrete tasks.
★ Agent action pre-check through Jentic
An AI agent about to take a consequential step can call the Marrow Agent Governance API through Jentic to evaluate the proposed action and get governance guidance before it runs, then commit the outcome with proof once it completes. Jentic returns the evaluate operation from a natural-language query, so the agent checks governance without reading the Marrow reference first.
Evaluate the proposed action against Marrow, proceed only if the guidance allows it, then close the action with its outcome and proof evidence.
Signed permit lifecycle
Issue a signed permit for a single governed action, verify it at execution time, heartbeat it while the action is in flight, and close it when done. Platform teams use this to keep a verifiable record that each sensitive action was authorized and completed within its permit.
Issue a permit for the governed action, verify it before execution, and close it with the final outcome once the action finishes.
Agent reliability reporting
Read tenant-scoped reliability, proof, outcome, and value metrics to show how a governed agent is performing over time. Operators use the report to spot drift in permit coverage and to demonstrate the agent stayed within its bounds.
Read the agent value report and the enforcement coverage, then summarize permit coverage and any configuration drift for the tenant.
11 endpoints — the marrow agent governance api evaluates an ai agent's proposed actions before they run and records proof of what happened after.

What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Marrow Agent Governance API by hand means handling its bearer API key, binding the agent, and coding the evaluate, permit, and commit calls in the right order yourself. Through Jentic you install once, import the API from the API Directory, store the key once, and your agent calls it.
Permission scoping
The governed agent operations carry no resource id in the URL path, so bound your agent to the operations it needs, such as reading context and evaluating actions. You choose which operations it may call, so issuing and closing permits is not included unless you add it.
Credential isolation
Your Marrow API key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'check if an action is allowed' or 'read agent context', and Jentic returns the matching Marrow operation with its input schema so the agent calls the right endpoint without reading the reference docs.

Specific to using Marrow Agent Governance API through Jentic.
Is there a Marrow Agent Governance API MCP server?
You do not need an MCP server to give your agent the Marrow Agent Governance API. Jentic connects it directly from the API Directory: import the API, store your key once, and your agent calls the context, evaluate, permit, and report operations. Operations are discovered on demand, so no extra server definitions load into the agent's context.
What authentication does the Marrow Agent Governance API use?
The agent operations require a Marrow API key passed as a bearer token per the OpenAPI spec, while the public health and discovery endpoints need no credential. Through Jentic the key is stored encrypted in your own Jentic One instance and supplied only when an authenticated call runs, so it never reaches the agent's context.
Can I evaluate an action before the agent runs it with the Marrow Agent Governance API?
Yes. The runtime evaluate operation takes a proposed action and returns governance guidance before execution, and a separate commit operation closes the action with its outcome and proof afterward. Together they bound what the agent does and leave a verifiable record of it.
What are the rate limits for the Marrow Agent Governance API?
The OpenAPI spec does not specify rate limits. A public status endpoint reports component health you can poll, and you can confirm the request limits for your tenant in the Marrow documentation at https://getmarrow.ai.
Can I limit what my agent is allowed to do with the Marrow Agent Governance API?
Yes. Write a rule that permits only the read operations, reading context and metrics, when the agent should observe governance, and add the permit and commit operations only for workflows that actually govern actions, with every call logged.
How do I evaluate an agent action with the Marrow Agent Governance API through Jentic?
Search Jentic for 'check if an agent action is allowed' to surface the evaluate operation, load its input schema, pass the proposed action, and execute, then commit the outcome once the action runs. To run it on your own infrastructure, install Jentic One from its GitHub repo.
For Agents
Govern an AI agent's actions: read its context, evaluate a proposed action before execution, issue and verify signed permits, close actions with proof evidence, and read reliability and value metrics.
Use for: Check whether a proposed agent action is allowed before running it, Read the operating context for the bound agent, Issue a signed permit for a single governed action, Close a completed action with its outcome and proof
Not supported: Does not handle user login, data storage, or payment authorization. Use for governing and permitting an agent's actions before and after execution only.
The Marrow Agent Governance API evaluates an AI agent's proposed actions before they run and records proof of what happened after. It reads the bound agent's identity, health, and tenant-scoped operating context, evaluates a proposed action and returns governance guidance, then closes the action with its outcome and proof evidence. It issues, verifies, and heartbeats signed permits for individual governed actions, reports action-permit coverage, and surfaces reliability and value metrics for the agent. Public health and discovery endpoints let a caller check status and probe whether governance is relevant before binding an agent.
