MCP tools · 20 exposed · ~2,406 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
colorstring–YELLOW, GREEN, BLUE or PURPLE.
contentstring–Note text, up to 4000 characters. Omit for a colour-only highlight.
docCodestringyes–
passwordstring–Plain document password, if the document has one.
quotedContentstring–Passage of the body this note points to, up to 4000 characters. Matched by text, so it survives edits elsewhere.
scopestring–PRIVATE (default) or SHARED.
textStartnumber–Character offset where the quote starts in the body. Optional; speeds up re-anchoring.

No output schema declared.

No examples provided.

postmd_create_document ~312

Publish Markdown as a PostMD web page. No API key required — anyone can publish. Returns docCode and data.shareUrl; hand shareUrl to people. Documents have a 30-day retention period (data.retainedUntil) that extends on each read. Documents without a password can be updated or deleted by anyone; password-protected documents require the password or the owner's API key. With an API key the document belongs to that member; groupId files it into that group (key with documents:write). The returned docCode can be kept at the top of the source file in a `postmd:document` comment (format at /docs/api) so a later session finds the document.

NameTypeReqDescription
fileNamestring–Upload filename, must end in .md. Default document.md.
groupIdnumber–File 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). May include graph data in an HTML comment, which the viewer draws; the format is at /docs/graph.
passwordstring–Readers must supply this password to see the content.
titlestring–Shown in the viewer and link previews. Defaults to fileName without .md.
viewerStylestring–Viewer 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 ~181

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.

NameTypeReqDescription
fileNamestring–Upload 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.
groupIdnumber–File the document in this group instead of the default group (needs an API key).
passwordstring–Readers must supply this password to see the content.
titlestring–Defaults to the file name without .md.
viewerStylestring–Viewer 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 ~148

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.
groupIdnumber–File every document in this group instead of the default group.
passwordstring–Readers must supply this password to see the content.
viewerStylestring–Viewer theme: readable (default), github, minimal, report, pamphlet or dark. Unknown values fall back to readable.

NameTypeReqDescription
namestringyes–

passwordstring–Document password if the document has one and you are not authenticated as its owner.

No output schema declared.

noteIdnumberyes–

No output schema declared.

No output schema declared.

No examples provided.

postmd_list_notes ~91

docCodestringyes–
passwordstring–Plain document password, if the document has one.

No output schema declared.

No examples provided.

postmd_move_document_to_group ~61

noteIdnumberyes–
resolvedbooleanyestrue marks it settled; false reopens it.

postmd_update_document ~315

Update a document. Password-protected documents require the password or the owner's API key; documents without a password can be updated by anyone.

Is the io.github.reinlainer/postmd-mcp-server server safe to use?

io.github.reinlainer/postmd-mcp-server scores 88 out of 100 on VerifyMCP. We recorded 6 known advisories against it as of 6 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the io.github.reinlainer/postmd-mcp-server server expose?

io.github.reinlainer/postmd-mcp-server exposes 20 tools: postmd_create_document, postmd_create_document_from_file, postmd_create_documents_from_files, postmd_get_document, postmd_get_document_raw, and 15 more. Their descriptions and schemas cost roughly 2,406 tokens of context every time the server is loaded.

Is the io.github.reinlainer/postmd-mcp-server server still maintained?

io.github.reinlainer/postmd-mcp-server is still listed as active in the MCP registry. We last reached this channel on 6 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the io.github.reinlainer/postmd-mcp-server server under?

io.github.reinlainer/postmd-mcp-server declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

What did VerifyMCP test on the io.github.reinlainer/postmd-mcp-server server?

VerifyMCP ran 16 checks on io.github.reinlainer/postmd-mcp-server, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
