Available components
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 Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token. See how to fix → View diagnostics → Fail
- 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
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability80
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 716 tokens (~71/item across 10 items; 9 tools + 1 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management10
- Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "bgpt_pdf_generator__delete_preview" implies "delete" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the Content Calendar Agent by Nova (CIVAI) MCP server?
Content Calendar Agent by Nova (CIVAI) is a hosted endpoint at https://nova.civai.co/mcp/agents/content-calendar-agent, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
bgpt_pdf_generator__delete_preview ~78
Delete one stored PDF draft by preview_id from this chat session only. Hidden from suggestion buttons — agent-only. Returns deleted true/false. Does not remove already-generated public PDF files. Never accept path-like ids.
| Name | Type | Req | Description |
|---|---|---|---|
| preview_id | string | yes | Hex preview_id from list_previews / get_preview in THIS session only |
No output schema declared.
No examples provided.
bgpt_pdf_generator__generate_pdf ~106
Generate a PDF from a preview. Call with no args first: if multiple previews exist, returns needs_selection + previews (title + preview_id) — ask the user which one, then call again with preview_id. If only one preview exists, generates it immediately. Returns pdf_url when generated.
| Name | Type | Req | Description |
|---|---|---|---|
| preview_id | string | – | Unique preview_id from a prior preview_document result. Omit to list choices (when multiple) or generate the only/last preview. |
No output schema declared.
No examples provided.
bgpt_pdf_generator__get_preview ~124
Preview PDF button. Call with no args first: if one draft exists, returns document_markdown; if multiple, returns needs_selection + previews — emit_display layout P (interaction_mode none) numbered picker only. NEVER collect_user_input or emit_display input for preview_id. After user replies with a number/title, call again with preview_id.
| Name | Type | Req | Description |
|---|---|---|---|
| preview_id | string | – | Optional. Omit on first Preview PDF tap so the tool can list drafts. Pass only after the user picks from the numbered list (or when chat already has a clear id). |
No output schema declared.
No examples provided.
bgpt_pdf_generator__list_previews ~66
List all stored PDF drafts in this session. Returns previews[{preview_id, title}], count, and most_recent_preview_id. Use when the user taps List PDFs or asks which drafts exist. Does not show document body — follow with get_preview after they pick.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
bgpt_pdf_generator__preview_document ~165
Write or revise draft markdown into session storage (creates preview_id). Agent-only — not a suggestion button. Use when the user asks to create/write/edit document content. For showing an existing draft use get_preview (Preview PDF). Never put emit_display chrome into content.
| Name | Type | Req | Description |
|---|---|---|---|
| content | string | yes | Full substantive markdown for the PDF pages (use --- between pages; each page needs a heading). Must be the document the user requested — never UI phrases like 'Here is a preview of your PDF document… |
