MCP tools · 21 exposed · ~2,862 tokens

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 →

Tool Tokens
postmd_add_note ~255

Attach a note or highlight to a document. Requires an API key with documents:write. Give `content` for a note, `color` alone for a colour-only highlight (then `quotedContent` is required — a highlight must point at a passage). Visibility comes from ownership: on the key member's own document choose PRIVATE (only they see it) or SHARED; on anyone else's document every note is SHARED, so omit scope. Documents nobody owns — anonymous uploads and service-owned pages — take no notes at all.

NameTypeReqDescription
colorstringYELLOW, GREEN, BLUE or PURPLE.
contentstringNote text, up to 4000 characters. Omit for a colour-only highlight.
docCodestringyes
passwordstringPlain document password, if the document has one.
quotedContentstringPassage of the body this note points to, up to 4000 characters. Matched by text, so it survives edits elsewhere.
scopestringPRIVATE (default) or SHARED.
textStartnumberCharacter offset where the quote starts in the body. Optional; speeds up re-anchoring.

No output schema declared.

No examples provided.

postmd_create_document ~294

Publish Markdown as a PostMD web page. No API key required — anyone can publish. Returns docCode and data.shareUrl; hand shareUrl to people. Without a key the document is anonymous: data.retainedUntil is when it is deleted and data.controlToken is the only way to update or delete it, shown once and never reissued — report both to the person. With an API key the document belongs to that member, has no expiry, needs no token and can collect notes; groupId files it into that group instead of the default one (key with documents:write).

NameTypeReqDescription
fileNamestringUpload filename, must end in .md. Default document.md.
groupIdnumberFile the document in this group instead of the default group (needs an API key).
markdownstringyesFull Markdown document as one UTF-8 string (the entire source, not a summary).
passwordstringReaders must supply this password to see the content.
shareEndDatestringyyyyMMdd. The document stops being served after this date. Omit for no end date.
titlestringShown in the viewer and link previews. Defaults to fileName without .md.
viewerStylestringViewer theme: readable (default), github, minimal, report, pamphlet or dark. Unknown values fall back to readable.

No output schema declared.

No examples provided.

postmd_create_document_from_file ~227

Same as postmd_create_document, but reads the Markdown from filePath on the machine running this MCP server — use it for large files instead of pasting the body. Without an API key it returns data.controlToken and data.retainedUntil, same as above.

NameTypeReqDescription
fileNamestringUpload filename. Defaults to the basename of filePath.
filePathstringyesPath to a .md file on the MCP server host, read as UTF-8. Prefer an absolute path.
groupIdnumberFile the document in this group instead of the default group (needs an API key).
passwordstringReaders must supply this password to see the content.
shareEndDatestringyyyyMMdd. The document stops being served after this date. Omit for no end date.
titlestringDefaults to the file name without .md.
viewerStylestringViewer theme: readable (default), github, minimal, report, pamphlet or dark. Unknown values fall back to readable.

No output schema declared.

No examples provided.

postmd_create_documents_from_files ~175

Publish several .md files in one call (bulk upload). Requires an API key with documents:write. The outer resultCode is 200 even if some files failed — check data.succeeded and each entry in data.results.

NameTypeReqDescription
filePathsarrayyesPaths to .md files on the MCP server host. Each becomes its own document.
groupIdnumberFile every document in this group instead of the default group.
passwordstringReaders must supply this password to see the content.
shareEndDatestringyyyyMMdd. The document stops being served after this date. Omit for no end date.
viewerStylestringViewer theme: readable (default), github, minimal, report, pamphlet or dark. Unknown values fall back to readable.

No output schema declared.

No examples provided.

postmd_create_group ~63

Create a group. Requires an API key with groups:write. Documents can then be filed into it and members invited from the web app.

NameTypeReqDescription
expireDatestringyyyyMMdd. The group stops working after this date.
namestringyes

No output schema declared.

No examples provided.

postmd_delete_document ~104

Delete a document. Requires an API key with documents:write for a document you own, or `controlToken` for an anonymously published one. There is no endpoint to undo this: the document stops being served at once and its stored content is erased about a month later.

NameTypeReqDescription
controlTokenstringControl token from an anonymous publish answer (pmt_...). Lets you act on that one document without an API key.
docCodestringyes

No output schema declared.

No examples provided.

postmd_delete_group ~48

Delete a group. Owner only; the default group cannot be deleted. Documents in it are not deleted. Requires an API key with groups:write.

NameTypeReqDescription
groupIdnumberyes

No output schema declared.

No examples provided.

postmd_delete_note ~53

Delete a note: your own, or a SHARED note on a document you own. Requires an API key with documents:write.

NameTypeReqDescription
docCodestringyes
noteIdnumberyes

No output schema declared.

No examples provided.

postmd_get_document ~78

Get document metadata by docCode: title, fileName, hasPassword, shareEndDate, viewerStyle, timestamps. Public — no API key needed. Content is not included; use postmd_get_document_raw for the Markdown source.

NameTypeReqDescription
docCodestringyesDocument code, e.g. P-123-456-789.

No output schema declared.

No examples provided.

postmd_get_document_raw ~65

docCodestringyes
passwordstringPlain document password, if the document has one.

No output schema declared.

No examples provided.

postmd_list_group_documents ~135

List documents in a group. Requires an API key with groups:read and documents:read. Paged; q searches title and file name (substring, case-insensitive).

NameTypeReqDescription
folderIdnumberOnly documents filed in this folder.
groupIdnumberyes
pagenumber
qstringSearch text for title and file name.
rootOnlybooleantrue → only documents not in any folder.

No output schema declared.

No examples provided.

postmd_list_notes ~91

List notes and highlights on a document: your own plus every SHARED one, newest first. Requires an API key with documents:read. Each note carries mine and manageable flags — trust them instead of re-deriving permissions. Pass `password` for a password-protected document.

NameTypeReqDescription
docCodestringyes
passwordstringPlain document password, if the document has one.

No output schema declared.

No examples provided.

postmd_move_document_to_group ~88

NameTypeReqDescription
docCodestringyes
folderIdnumberFile it into this folder of that group.
groupIdnumberyes

No output schema declared.

No examples provided.

postmd_resolve_note ~82

NameTypeReqDescription
docCodestringyes
noteIdnumberyes
resolvedbooleanyestrue marks it settled; false reopens it.

No output schema declared.

No examples provided.
