Postman Passport, Keycard, Infisical Agent Vault and Bruno's MCP server each help a coding agent reach an API. None is an API client. This page sets out what each does, where it is stronger, and what Porticol adds.

## What Porticol does differently

- **It approves one exact call.** A person sees the request and allows that request alone, once, for 10 minutes.
- **It starts on your computer.** The desktop app and the CLI hold the policy and inject the keys; a team can add a gateway on its own server for production.
- **It is priced per seat.** Free for one person, $9 a seat a month for Team and $19 for Business. [See pricing](https://porticol.app/pricing).

## At a glance

|  | Porticol Checked 9 Nov 2026 | Postman Passport Checked 9 Nov 2026 | Keycard Checked 9 Nov 2026 | Infisical Agent Vault Checked 9 Nov 2026 | Bruno's MCP server Checked 9 Nov 2026 |
| --- | --- | --- | --- | --- | --- |
| Keeps keys away from the agent | Yes. MCP never passes key values to the agent; the local proxy injects them. [8] | Yes. A caller holds a credential reference, and the proxy in your network resolves the real key. [1] | Partly. Coding agents get short-lived credentials as environment variables; only its MCP gateway keeps the token from the agent. [4] | Yes. A forward proxy injects the key, and the agent never sees it. [6] | Partly. It masks known credential headers and secret variables, but other headers and bodies come back as they are. [7] |
| Approves one exact call | Yes. An approval is bound to a hash of the exact request, single use, 10 minutes. [8] | No. An admin approves access to an API; no one approves a single call. [9] | No. Calls are allowed or denied by policy, with a one-time sign-in or consent; no person approves a single call. [4] | No. Firewall rules for requests are planned; a person cannot approve a single call. [6] | No. A request runs when the agent asks; no person approves the call. [7] |
| Records every agent call | Yes. A hash-chained log records every agent call. [8] | Yes. Every request is logged against the caller's identity. [9] | Yes. Every action is recorded as telemetry with its identity; 7 days on Starter and 90 on Team. [5] | Yes. It logs each proxied request; bodies and query strings are not recorded. [6] | No. It returns a run's results to the agent and keeps no log of its own. [7] |
| Runs on your computer | Yes. Desktop app and CLI; the team gateway on your server. [8] | No. A local daemon sends requests to the proxy in your cloud. [9] | No. Policy and credentials are handled in Keycard's cloud; running it in your own cloud is listed as coming soon. [5] | Partly. You run its proxy on your own servers, and it needs an Infisical Cloud organisation or a self-hosted Infisical. [6] | Yes. The server runs on your computer over the collections on disk. [7] |
| Price for a small team | $9 a seat a month (Team), $19 (Business); Free for one person [10] | Not published: contact sales [11] | $0 up to 5,000 transactions a month; Team $500 a month for 100,000 transactions [5] | In preview: the first 5,000 requests a month are free on the Pro plan, then $2 per 1,000 [12] | Free [7] |

## Where they are stronger

### Postman Passport

Postman's secret-free access product, with a proxy that runs in your network.

- It resolves credentials from your own vault inside a proxy in your network. [1]
- It scopes access to an exact endpoint and checks the caller on every request. [2]
- An agent gets a short-lived identity, and agents it starts inherit only part of its access. [3]

### Keycard

An access control plane for agents, with policy, sign-in consent and telemetry.

- It gives each agent short-lived credentials scoped to its task. [4]
- It is free up to 5,000 transactions a month. [5]
- Its policy can combine roles, attributes and relationships across agents and people. [5]

### Infisical Agent Vault

A credential proxy that injects keys into an agent's HTTP traffic, in preview.

- It keeps keys out of the agent by injecting them at a proxy it runs beside. [6]
- It works below the interface, so curl, SDKs, MCP clients and scripts all go through it. [6]
- It logs every proxied request with its method, endpoint, status and latency. [6]

### Bruno's MCP server

A local MCP server that lets an agent read and run Bruno collections.

- It is free and open source under the MIT licence. [7]
- It works from the collection folder Bruno already uses, with no import. [7]
- It masks known credential headers and secret variables before a result reaches the agent. [7]
