Permit
Pre-execution action authorization for AI agents — a deterministic, signed gate on every tool call before it runs.
If your agents move money, touch claims, or write regulated data, pre-execution authorization is the right shape, and Permit0 is a serious take on it: rules and cryptography in the hot path, with a model allowed only to deny or escalate. The parts that matter aren't the block/allow demo — they're the open 21-domain taxonomy and the signed, replayable decision record an auditor can verify. Budget for the fact this is beta with a working-draft architecture spec.

Skip Permit0 if you need to monitor agent reasoning and tracing after the fact, or if you are prototyping a chatbot that never executes tool calls — this is a gate in front of execution, not an observability platform.
Audit-of-record per decision and compliance mappings land on the paid Cloud Pro tier, so regulated teams cannot stay on the free entry point.
Permit0's published tiers run from a free open-source SDK and a free Cloud Starter up to Cloud Pro at $49/mo and Cloud Growth at $499/mo, with Enterprise priced as Custom. That lands it well below enterprise agent-governance suites sold as platform contracts, and comfortably above generic observability tooling that does not make authorization decisions. The $499/mo Cloud Growth tier is where multi-team and multi-framework deployments actually live.

What is Permit?
Permit — Pre-execution action authorization for AI agents — a deterministic, signed gate on every tool call before it runs. Best for Fintech and payments teams gating refunds, transfers, and ledger writes before they execute, Insurtech and claims teams needing pre-execution evidence for EU AI Act Annex III, Platform leads consolidating authorization across LangChain, CrewAI, AutoGen, and MCP. Free to start; paid plans from $49/mo.
Permit0 is an action authorization layer for AI agents. It sits between what an agent decides to do and what actually executes, so a refund, transfer, claim decision, or ledger write gets scored and cleared (or stopped) before the tool call fires. You wrap a function with a single decorator, @permit0.guard("payments.refund"), and the call routes through a deterministic policy engine that returns allow, block, or escalate. In the vendor's own example, a $25 refund processes while an $8,500 refund is blocked at risk 82/100, tier HIGH, flags FINANCIAL·MUTATION, and routed to human review. The platform is three components. Permit0 Engine holds the Tool Action Compiler, which normalizes any tool call into a canonical action across 21 domains, and the Risk Engine scoring against 9 risk flags and 10 amplifiers. An optional LLM reviewer can only deny or escalate, never approve. Permit0 Taxonomy is an open, versioned, citable vocabulary of agent actions across those domains, each scored across 9 risk dimensions with opinionated defaults. The Compliance Center produces audit-of-record evidence mapped to frameworks including the EU AI Act, Colorado AI Act, NIST AI RMF, ISO 42001, SOC 2, FINRA, HIPAA, and SR 11-7. Cryptographic capability tokens in PASETO v4.public format bind approved actions to payload hashes, constraint envelopes, and decision provenance, so a prompt injection cannot slip past a signed gate. A session-aware chain detector catches risky action sequences, and a global kill switch keeps override authority in every deployment mode. The stack coverage is deliberately cross-platform: LangChain, Model Context Protocol, CrewAI, OpenClaw, AutoGen, LangGraph, the OpenAI Agents SDK, Claude Code, and raw Python tools. Deploy cloud, self-hosted, or in a managed VPC. It's aimed at fintech, insurtech, and healthtech teams pushing agents into production under a real auditor.

Behind the verdict
We'd reach for Permit0 the moment an agent's tool call can do something you can't easily undo: a refund, a transfer, a claim denial, a bureau-furnishing write. Post-hoc tracing tools tell you what happened. Permit0 decides whether it happens at all, in real time, before execution — and that distinction is the whole product. Who should pick it: platform leads juggling authorization logic reinvented separately in LangChain, CrewAI, and MCP; CISOs who want a signed gate that a prompt injection can't talk its way around; compliance owners in fintech, insurance, or healthtech who need pre-execution evidence mapped to SR 11-7, the EU AI Act, or NAIC bulletins. The single-decorator integration and free OSS SDK mean a pilot is cheap to try. Who should pass: teams that only want observability or trace exports; anyone hunting a no-code agent builder; simple chatbots that never call tools. If your real need is governing which agents exist rather than which actions run, that's an identity-layer problem, not this one. The closest mental comparison is Okta's agent gateway or a platform-native control like Agentforce or Microsoft Agent 365. The catch with those is scope: they govern actions inside their own boundary. Permit0's pitch is cross-platform — one policy whether the call reads from Salesforce and refunds through Stripe. Real-world caveats. The decision path is deterministic by design, which is the selling point and also the constraint: your policy quality is your ceiling, and a bad rule blocks good transactions. The 21-domain taxonomy is opinionated — you'll be adopting someone's risk defaults, so read them. This is beta with a design-partner program, and the architecture spec is a draft, not a finished document. Pair it with an observability tool rather than replacing
Limitations
- Permit0 is in beta with a design partner program aimed at fintech, insurtech, and healthtech teams shipping agents into production, so early adopters absorb early-stage roadmap and support risk alongside founder access.
- It is pre-execution authorization rather than observability: it gates actions before they run but does not monitor agent behavior that never passes through the gate, so you will still want a tracing tool alongside it.
- The architecture spec is published only as a working draft — the <5ms p99 latency target, the 7-stage Tool Action Compiler, the 9-flag × 10-amplifier Risk Engine, and the PASETO v4.public token design are described structurally, with the full document available via a founder call rather than on the public site.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Permit actually fits — and what changes day-one when you adopt it.
Wrap the payments.refund tool with @permit0.guard("payments.refund"), install the SDK via pip, and let the default policy set block refunds above the configured threshold.
Outcome: In the vendor's example, a $25 refund is allowed through to Stripe while an $8,500 refund is blocked at risk 82/100 with flags FINANCIAL·MUTATION and escalated to human review before the call fires.
Normalize agent tool calls from LangChain, CrewAI, and AutoGen through the Tool Action Compiler so a single policy governs every framework, and turn on session-aware chain detection.
Outcome: One policy and one audit trail across frameworks, with dangerous action sequences caught and escalated instead of each team reinventing authorization inside agent code.
Route every agent action through the gate and export the signed DecisionRecord trail for the frameworks the auditors already use.
Outcome: Replayable, cryptographically signed audit-of-record evidence per decision, pre-mapped to EU AI Act, NIST AI RMF, ISO 42001, SOC 2, HIPAA, and SR 11-7.
Use cases
- Block a refund action automatically when the amount exceeds a configurable threshold without human approval
- Escalate a sequence of sensitive agent actions, such as reading PII then transferring funds, for human review
- Enforce one compliance policy across agents built with LangChain, CrewAI, and AutoGen without rewriting per framework
- Audit every pre-execution decision with signed, replayable logs for SOC 2 or DORA reviews
- Protect production agents from executing dangerous mutations like deleting records or initiating payments
- Define custom action taxonomies and risk amplifiers for domain-specific agent behavior
Setup time & first value
How long it actually takes to get something useful out of Permit — broken out by persona, not the marketing-page minute.
For developers, the vendor states a 5-minute integration with LangChain, MCP, CrewAI, OpenClaw, and raw Python tools: pip install the open-source SDK, add the @permit0.guard decorator, and you have default actions across 21 domains on day one. Platform and compliance teams should budget longer — mapping your internal action taxonomy to the 21 domains, wiring the policy plane into your frameworks,
Switching to or from Permit
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From hand-rolled permission checks in agent code: replace inline authorization logic with the @permit0.guard decorator so policy lives centrally instead of per tool call.
- ↗To a post-execution observability or tracing tool: export the signed DecisionRecord trail as the audit layer and hand runtime tracing to the observability platform.
- ↗To an identity-layer governance product: keep the action-level policy where it adds value and move agent existence and credential management to the identity layer.
