  • Choose an aggregated tool

  • Discover action resources

What it does

Siyuan MCP Sisyphus is an agent skill from yangtaihong59/siyuan-plugins-mcp-sisyphus. Top-level skill for operating SiYuan Note through the Sisyphus MCP server. Use to choose an aggregated tool, discover action resources, route complex tasks to a scenario skill, and apply permissions and safety rules.

Its SKILL.md is about 1.3k 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. 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

  • Choose an aggregated tool
  • Discover action resources
  • Route complex tasks to a scenario skill
  • Apply permissions and safety rules

Example prompts

  • “/siyuan-mcp-sisyphus”

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.

    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 Sisyphus loads about 1.3k tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 589 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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.

Top-level skill for operating SiYuan Note through the Sisyphus MCP server. Use to choose an aggregated tool, discover action resources, route complex tasks to a scenario skill, and apply permissions and safety rules.

SiYuan Sisyphus with MCP

Use the narrowest scenario skill that matches the task. For unfamiliar fields, inspect siyuan://help/tool-overview and the relevant siyuan://help/action/{tool}/{action} resource before calling an action; live action help is the parameter-level source of truth.

Tool choice

Prefer fs for ordinary human-readable workspace paths. Use document or block for IDs, storage paths, metadata, or block-granular changes. Use av for real databases rather than Markdown tables. Use timeline for named snapshots, document diffs, and rollback. Low-complexity feedback and mascot actions need no separate scenario skill.

The CLI, a raw MCP payload, and an Agent-generated call are invocation forms, not proof that Sisyphus strict-write handling ran. For a protected mutation, follow the selected runtime's current help and returned safety fields. The documented preflight, single-attempt transport, idempotency, and readback guarantees apply only when the call is routed through the active Sisyphus write coordinator with strict mode enabled. Do not infer kernel-level compare-and-swap or parity with native SiYuan and third-party calls.

Operation risk before routing

Classify the requested operation before choosing a surface: R is read or discovery; W1 is an additive or local write; W2 changes structure, references, assets, or attribute-view data; W3 affects notebooks, imports, sync, history, or workspace-wide state. Use the narrowest surface and confirmation appropriate to the tier. Treat an undocumented or uncertain operation as the higher-risk tier until current action help and returned policy fields establish otherwise. This is routing discipline, not a replacement for the current action schema or safety policy.

Help without MCP Resources

The complete layout guide is available through the help action below, using the same content as the MCP layout resource. Never pass a help URI to the document read action.

Shared invariants

  • Read /AGENTS.md through fs before workspace-aware tasks when it exists.
  • A workspace path such as /Notebook/Folder/Doc, an hpath such as /Folder/Doc, and a storage path such as /20260712123000-abc123.sy are different values.
  • Resolve the exact target before mutating: map a human path or search candidate to the returned stable ID and retain its notebook, hpath, and storage path. Never derive an opaque ID or storage path from a title, and never treat a candidate list as the final target.
  • Read before writing; after a mutation, read the affected object again.
  • Document reads try full text by default, capped at 256 KiB UTF-8 and 2000 complete blocks; a single oversized block fails explicitly. Outlines and database hints cover the returned window, and totalBlocks is null until EOF.
  • Keep reads bounded and prove completeness: use nextWindow or explicit blockStart/blockLimit/tokenBudget for documents, and page parameters for lists and searches. Continue while another page/window is advertised, then reread the exact affected ID/path and compare the intended field or status.
  • If a write response is lost, or the result is outcome_unknown or readback_mismatch, stop and inspect the exact target. Do not resend with a new requestId merely because the acknowledgement was missing.
  • Missing results may be caused by notebook permissions or indexing delay.
  • Obtain explicit approval before deletes, moves, bulk replacement, permission changes, local upload/export, or sensitive workspace disclosure.
