## Quality 68/100 (needs work)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 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: 71 (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
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: render_og_image (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); og_pricing (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); og_image_from_url (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 611 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 50 (weight 15)

- pass `stability.changes`: 2 tool changes in 30 days
- fail `stability.rug_pull`: 2 tools kept their name but changed most of their description in 30 days; review before trusting them

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

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

- tools: 3, about 611 tokens to load them all
- tool set hash: 24a5f446ba93f61c4e926995c8dd7268
- tools last changed: 2026-09-28T12:30:46.206Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.ogstamp/og.svg)](https://protogrid.dev/servers/com.ogstamp/og)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-09-28 `og_image_from_url` changed (description, inputSchema) **meaning changed**
  - before: Build an Open Graph card for an existing public page with no fields to fill in: OG Stamp fetches the page and uses its title, description, favicon and theme-color. Returns a stable image URL you can paste straight into og:image. Any field can be overridden.
  - after: Build a hosted Open Graph card from a public page (title, description, favicon, theme-color) and return https://ogstamp.com/i/{id}.png. Requires api_key. One credit. Does not return a free hotlink.
- 2026-09-28 `render_og_image` changed (description, inputSchema) **meaning changed**
  - before: Build a 1200x630 Open Graph PNG. Supports title, subtitle, badge, theme, logo_url (https), and hex colors bg/fg/accent. Free light use is watermarked and capped per site (10/day). Production: POST https://ogstamp.com/api/og with Bearer ogs_…. Add store=1&format=json to get a stable hosted https://ogstamp.com/i/{id}.png URL for og:image (no key in HTML). Buy credits: https://ogstamp.com/pricing/.
  - after: Build a hosted Open Graph PNG and return a stable https://ogstamp.com/i/{id}.png URL for og:image. Requires api_key (ogs_… from https://ogstamp.com/pricing/). One credit per image. Does not return a free hotlink.
