# OSA Procurement Guard

> Pre-purchase trust, pricing and budget decisions for AI agents buying APIs and MCP tools.

- name: io.github.omarfff/osa-procurement-guard
- version: 0.2.2
- connection class: R1 (autonomous)
- trust: 94/100
- quality: 85/100 (good)
- owner: not claimed
- descriptor: https://api.protogrid.dev/v1/servers/io.github.omarfff%2Fosa-procurement-guard
- tools: https://api.protogrid.dev/v1/servers/io.github.omarfff%2Fosa-procurement-guard/tools

**An agent can connect on its own if it already holds `X_API_KEY`, `X_API_KEY`.** Remote endpoint behind a static API key or header. The registry never sees the value; the agent fills the placeholder.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "osa-procurement-guard": {
      "type": "http",
      "url": "https://pkctqxeydfuiupadaoov.supabase.co/functions/v1/procurement-mcp",
      "headers": {
        "X-API-Key": "${X_API_KEY}",
        "Authorization": "${X_API_KEY}"
      }
    }
  }
}
```

Placeholders to fill: `${X_API_KEY}`, `${X_API_KEY}`.

## Trust

- hygiene: 100
- liveness: 100
- freshness: 85
- provenance: 90
- drivers: +repository +namespace-matches-repo +website +reachable +uptime-100% ~updated-58d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 85/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 1 of 1 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: procurement_decision (destructiveHint, idempotentHint)
- pass `tools.token_cost`: about 227 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 1, about 227 tokens to load them all
- tool set hash: 54dddcb668999ccadd254926d72b5dc8
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.omarfff/osa-procurement-guard.svg)](https://protogrid.dev/servers/io.github.omarfff/osa-procurement-guard)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
