MCP SiYuan markup guide for rich Markdown written through block and document actions.

  • Block references
  • SKILL.md covers Common markup, Math and diagrams and SiYuan-specific forms
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve MCP servers

What it does

Siyuan MCP Markup Guide is an agent skill from yangtaihong59/siyuan-plugins-mcp-sisyphus. MCP SiYuan markup guide for rich Markdown written through block and document actions. Use for headings, lists, tasks, tables, code, math, diagrams, tags, callouts, super blocks, embeds, and block references.

Its SKILL.md is about 410 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Agent Workflows, covering MCP servers and Diagrams. It works with Model Context Protocol. The repository describes itself as: 一个用于连接Agent与Siyuan的工具. The licence is MIT.

When your agent uses it

  • Block references
  • Tasks that involve MCP servers
  • Tasks that involve Diagrams

Example prompts

  • “/siyuan-mcp-markup-guide”

What it can do on your machine

Read from SKILL.md and the folder at commit d2ad534. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Siyuan MCP Markup Guide loads about 405 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 110 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~405

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SiYuan Markup Guide with MCP

Pass rich content as Markdown to block or document write actions. Keep each write bounded and read the result after insertion.

text
block(action="append", parentID="<doc-id>", dataType="markdown", data="## Heading\n\nParagraph with **bold** text.")

Common markup

markdown
# Heading

**bold**, *italic*, ~~deleted~~, ==highlight==, `inline code`, #tag#

- Item
  - Nested item
- [ ] Task

| Name | Status |
| --- | --- |
| Draft | Done |

> **Note**

> Keep evidence with the decision.

Use an attribute view for real database behavior rather than a Markdown table.

Math and diagrams

markdown
Inline: $e^{i\pi}+1=0$

$$
\int_0^1 x^2 dx = \frac{1}{3}

```

SiYuan-specific forms

  • Block reference: ((<block-id> "Optional label"))
  • Embed query: {{SELECT id, content FROM blocks WHERE content LIKE '%TODO%' LIMIT 20}}
  • Horizontal super block: wrap sibling blocks in {{{row and }}}.
  • Vertical super block: wrap sibling blocks in {{{col and }}}.
  • IAL attributes: {: custom-key="value"}; use dedicated attribute actions for programmatic metadata.

Do not invent unsupported Markdown extensions. For detailed layout rules or unfamiliar write fields, inspect siyuan://help/action/block/append before writing.
