How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security89
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents. View diagnostics → Partial
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability78
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 9167 tokens (~218/item across 42 items; 41 tools + 1 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 4 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 43 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
- Supports UI / widget rendering.Pass

show_post_card Show a Postlyra post in chat ~115
Use this when the author asks to open an existing post card, requests another card or reports a missing card. Do not call automatically after create_post_draft: it already attaches a card, so another call duplicates it. Find postId with search_posts/search_post_drafts. Renders preview and publication controls in MCP Apps hosts; a browser preview link is different. Never publishes, schedules or enables a public link.
| Name | Type | Req | Description |
|---|---|---|---|
| postId | string | yes | Owner-bound postId from search_posts/search_post_drafts/create_post_draft. |

update_post Edit Postlyra working content ~240
Edit a post's working content, title, buttons or attention flag. Pass expectedRevision from get_post or the last mutation. On revision_conflict, reread and compare changes; reapply only intended edits with the current revision. Never bypass revision checks. Scheduled and sent messages keep their snapshots until apply_post_to_publication is requested.

update_post_draft Update a Postlyra post draft ~619

Image references/files are imported; arbitrary RichDocument media.src may remain external. Never publishes.
