TL;DR
IdeaNavigator AI proposes testing per-action authorization for autonomous agents through a proxy placed in front of one high-risk API. The system would issue single-use, signed tokens for specific actions and record approvals and denials; its security benefits, latency and commercial viability have not yet been demonstrated.
IdeaNavigator AI has proposed a pilot security workflow that would require autonomous AI agents to obtain approval for each high-risk API action, rather than operate with broad, standing credentials. The proposal targets platform engineers deploying agents that can make changes or contact customers, but it describes a product concept and validation plan, not a reported deployment or tested security result; related considerations are discussed in AI agent security and guardrails.
The proposed product is a proxy between an agent and a high-risk API. Before carrying out an action, the agent would request a signed, single-use token specifying the exact action and its arguments. The proxy would apply policy rules, then grant or deny the request and record the decision for an audit trail. The suggested minimum viable product would cover one API, rather than attempting to govern every tool an agent might use.
IdeaNavigator AI identifies refunds and record deletion as examples of actions that could cause harm if an agent acts on a prompt-injection attack or makes a reasoning error, risks also relevant to coding agent security. It says teams may give agents broad API tokens that allow such actions without a separate, scoped approval for each one. Those risks are presented as the problem the proposed product aims to address; no incident data or measured reduction in unsafe actions is supplied.
The suggested test is to put one team’s refund or delete endpoint behind the proxy for one month, require per-action tokens, and compare blocked unsafe actions and added latency with the team’s unscoped baseline. The proposal also sketches a business model: usage-based charges per authorized action, plus a platform fee for policy and audit tools. No pricing, customer commitment or pilot outcome is reported.
Agent Security · Proposal Brief
Per-Action Authorization: A Foundation for Agent Security
IdeaNavigator AI proposes a checkpoint for high-risk agent actions: request approval for one specific API operation, then issue a signed, single-use token. The concept and its security, latency, and commercial viability have not yet been demonstrated.
01 / The security gap
Check before high-risk API calls
An agent with a broad credential may be able to change records, issue refunds, delete data, or contact customers without a fresh decision for each operation. Per-action authorization aims to put a reviewable policy check in that request path.
Broad credentials
A token granted in advance can enable sensitive calls without a separate, scoped approval at the point of use.
Specific request
The agent would request a signed token tied to the exact action and its arguments before the protected API call.
Impact unmeasured
No incident data, security evaluation, or measured reduction in unsafe actions is reported.
Examples include refunds and record deletion. The proxy could log allowed and denied requests, but safety would still depend on sound policies, token design, implementation, and preventing bypass.
Intended safeguard02 / Proposed request path
From agent intent to audited decision
The proxy would sit in front of one selected high-risk endpoint. The underlying API remains in place; the proposal inserts policy enforcement into its request path.
Request
Agent specifies an operation and its arguments for the protected endpoint.
Evaluate
Proxy checks the request against configured policy rules.
Authorize
Grant or deny; a grant would use a signed, single-use token for that request.
Record
Log the decision to support review and later investigation.
Conceptual flow only · No implementation or technical standard specified
03 / What a pilot could establish
Security gains still need testing
The suggested evaluation compares one controlled endpoint with the team’s current unscoped baseline. The proposal does not define the measurement method or report outcomes.
Measure in the pilot
Suggested comparison for one refund or deletion workflow over one month.
Illustrative tracks, not results. No values, thresholds, or acceptable latency targets are provided.
Questions still open
These details affect whether the proposed control can work safely in practice.
04 / Suggested validation
A one-month endpoint pilot
The proposal recommends starting with one team and one high-risk endpoint, keeping the scope small enough to observe the operational trade-offs.
month
Put a refund or deletion endpoint behind the proxy and require per-action tokens.
Select one endpoint
Choose a team’s refund or delete workflow; no participating team is named.
Apply per-action checks
Route each protected request through policy evaluation and authorization.
Track decisions
Record attempts allowed or blocked, and define what qualifies as unsafe.
Report trade-offs
Compare blocked actions and measured latency with the unscoped baseline.
05 / Reader questions
What the proposal does—and does not—say
What is per-action authorization?
A proposed control that asks an agent to obtain approval for a particular operation and its arguments before calling a protected API.
How is it different from OAuth scopes?
The proposal characterizes scopes as relatively broad, standing access. Its approach would authorize individual requests; the practical difference still needs evaluation.
Has it been tested?
No test results are reported. A one-month pilot is suggested, with blocked unsafe actions and added latency as measures.
Is there a commercial offering?
A usage-based charge per authorized action plus a platform fee is sketched. Pricing, customer commitments, and pilot outcomes are not reported.
Traceability / Evidence status
An early hypothesis, awaiting evidence
The concept outlines a possible control and a way to test it. Until a pilot reports policy setup, unsafe-action criteria, bypass resistance, and latency, it is not evidence of a proven safeguard or established market offering.
A Check Before High-Risk API Calls
The idea addresses a security gap between an agent’s ability to call tools and the permissions attached to its credentials. A broad token can give an agent standing access, while per-action authorization is intended to constrain a particular request by action and arguments. If the control works as proposed, teams could review and record individual high-impact operations instead of relying only on general access scopes.
That distinction matters as organizations give software agents the ability to change records, issue refunds or send messages. A policy check and audit record could help teams identify which requests were allowed or blocked and investigate later. But the concept does not itself establish that an agent’s request is safe: its effectiveness would depend on the policies, token design, proxy implementation and the ability to prevent actions from bypassing the proxy. The proposed month-long test is meant to examine some of these operational questions, including blocked actions and added latency.

From Standing Tokens to Single Actions
The proposal is framed around a change in how AI agents are being used: systems that call tools can move beyond generating text and take actions through APIs. In that setting, access granted in advance may allow an agent to perform operations without a fresh decision at the point of use. IdeaNavigator AI characterizes existing OAuth scopes as coarse and suited to standing access, rather than time-limited approval for a specific action.
The proposed proxy would not replace the underlying API. Instead, it would sit in the request path for one selected endpoint, enforce rules and log each decision. Starting with a single refund or deletion workflow would make it possible to compare the controlled setup with the team’s existing unscoped approach. The proposal does not describe a specific technical standard, implementation, customer, or organization that has already adopted the system.
Security Gains Still Need Testing
No working product, customer trial, performance result or security evaluation is described. It remains unclear how the proxy would verify that a requested action and its arguments match the agent’s intended task, how policies would be configured, and what safeguards would prevent an agent or compromised system from bypassing the proxy. The proposal also gives no details on token expiration, signing infrastructure, failure handling or integration with existing identity systems.
The suggested pilot would measure blocked unsafe actions and latency, but the method for deciding which requests are unsafe is not specified. Nor does the proposal state what latency would be acceptable, how results would be compared, or whether the approach would work across different APIs and agent frameworks. The cited concern about broad credentials is a motivating risk, not evidence that the proposed design has already reduced incidents.
A One-Month Endpoint Pilot
The next step in the proposal is a one-month test with a team’s refund or deletion endpoint placed behind the proxy. That would allow the team to observe authorization decisions, track attempted actions that policy blocks and measure the added delay against its current unscoped setup. The material does not identify a participating team or say that the test has begun.
Any assessment would need to report how the policy rules were set, what counted as an unsafe action, whether the proxy could be bypassed and how latency was measured. Until such findings are available, the proposal remains an early product hypothesis in the agent security and authorization market, rather than evidence of a proven safeguard or established commercial offering.

Key Questions
What is per-action authorization for an AI agent?
It is a proposed control requiring an agent to obtain approval for a specific operation and its arguments before calling a protected API. The suggested approval would use a signed, single-use token.
How would the proposed system work?
A proxy would sit between an agent and one high-risk API, check each request against policy rules, grant or deny it, and log the decision. The proposal does not provide implementation or test results.
Has the security approach been tested?
No test results are reported. IdeaNavigator AI suggests a one-month pilot on one team’s refund or delete endpoint, with blocked unsafe actions and added latency as measures.
How is this different from OAuth scopes?
The proposal characterizes OAuth scopes as granting relatively broad, standing access. Its suggested approach would authorize individual actions with tokens limited to a particular request; the practical difference would need to be evaluated in a pilot.
What remains unknown about the proposal?
There is no named customer, deployed product, pricing detail or evidence of reduced risk. Technical questions include how policies would be set, how bypasses would be prevented and what latency the proxy would add.
