Use the SiYuan kernel API via curl to search, read, create, update, and delete blocks and documents in a self-hosted knowledge base. No extra tools needed — just curl and an API token.
Install and run SiYuan (desktop app or Docker container).
Get your API token: Settings > About > API token in the SiYuan desktop app.
Store credentials in ${HERMES_HOME:-~/.hermes}/.env:
SIYUAN_TOKEN=your_token_here
SIYUAN_URL=http://127.0.0.1:6806
SIYUAN_URL defaults to http://127.0.0.1:6806 if not set.
Ensure curl and jq are available on PATH.
Windows (PowerShell) note: In PowerShell, use $env:SIYUAN_TOKEN and $env:SIYUAN_URL instead of $SIYUAN_TOKEN. For multi-line JSON bodies, prefer writing the JSON to a temp file and using -d "@file.json" to avoid quoting issues, or use single-quoted here-strings.
All SiYuan API calls are POST with a JSON body — even read-only operations. Never use GET.
Every request follows this pattern:
curl -s -X POST "${SIYUAN_URL:-http://127.0.0.1:6806}/api/..." \
-H "Authorization: Token $SIYUAN_TOKEN" \
-H "Content-Type: application/json" \
-d '{"param": "value"}'
Responses are JSON:
{"code": 0, ...
code: 0 means success. Any other value is an error — check msg for details. Always verify code == 0 before processing data.
ID format: SiYuan IDs look like 20210808180117-6v0mkxr (14-digit timestamp + 7 alphanumeric chars). Reject any ID that does not match the pattern YYYYMMDDHHmmss-xxxxxxx.

curl -s -X POST "${SIYUAN_URL:-http://127.0.0.1:6806}/api/notebook/lsNotebooks" \
-H "Authorization: Token $SIYUAN_TOKEN" \
-H "Content-Type: application/json" \
-d '{}' | jq '.code, .data.notebooks[] | {id, name, closed}'
If code is not 0, the token or URL is wrong.
curl -s -X POST "${SIYUAN_URL:-http://127.0.0.1:6806}/api/search/fullTextSearchBlock" \
-H "Authorization: Token $SIYUAN_TOKEN" \
-H "Content-Type: application/json" \
-d '{"query": "meeting notes", "page": 0}' | jq '.data.blocks[:5]'
Query the blocks database directly. Only SELECT statements are safe. Never send INSERT, UPDATE, DELETE, or DROP.
curl -s -X POST "${SIYUAN_URL:-http://127.0.0.1:6806}/api/query/sql" \

-d '{"stmt": "SELECT id, content, type, box FROM blocks WHERE content LIKE '\''%keyword%'\'' AND type='\''p'\'' LIMIT 20"}' | jq '.data'
Useful columns: id, parent_id, root_id, box (notebook ID), path, content, type, subtype, created, updated.
Returns block content in Kramdown (Markdown-like) format.

YYYYMMDDHHmmss-xxxxxxx. Reject anything else before making API calls.code != 0 in responses before processing data. The msg field contains the error message.LIMIT in SQL and pipe through jq to extract only what you need.lsNotebooks — do not assume the notebook name is the ID.custom-. Attributes without this prefix may be ignored or overwritten by SiYuan internals.curl -d "@body.json" to avoid quoting hell.lsNotebooks returns both open and closed notebooks. Filter on closed if you only want accessible notebooks.Check token and connectivity:
curl -s -X POST "${SIYUAN_URL:-http://127.0.0.1:6806}/api/notebook/lsNotebooks" \
-H "Authorization: Token $SIYUAN_TOKEN" \
-H "Content-Type: application/json" \
-d '{}' | jq '.code'
Expected output: 0
Verify a search returns results:
curl -s -X POST "${SIYUAN_URL:-http://127.0.0.1:6806}/api/search/fullTextSearchBlock" \
-H "Authorization: Token $SIYUAN_TOKEN" \
-H "Content-Type: application/json" \
-d '{"query": "test", "page": 0}' | jq '.data.blocks | length'
Expected output: a non-negative integer.
Verify a block read succeeds:
curl -s -X POST "${SIYUAN_URL:-http://127.0.0.1:6806}/api/block/getBlockKramdown" \
-H "Authorization: Token $SIYUAN_TOKEN" \
-H "Content-Type: application/json" \
-d '{"id": "20210808180117-6v0mkxr"}' | jq '.code, .data.kramdown'
Expected: 0 followed by the block's Kramdown content.
If you prefer a native integration instead of curl, install the SiYuan MCP server:
# In ~/.hermes/config.yaml under mcp_servers:
mcp_servers:
siyuan:
command: npx
args: ["-y", "@porkll/siyuan-mcp"]
env:
SIYUAN_TOKEN: "YOUR_TOKEN"
SIYUAN_URL: "http://127.0.0.1:6806"
