Merge, split, stamp and read PDFs, pure JavaScript, no upload. It merges and splits PDFs, extracts and reorders pages, rotates a sideways scan, stamps PAID or DRAFT or any text, watermarks the business name and VAT id from the shared profile, and reads text back best effort with no OCR.
pdf_info, pdf_count and pdf_text are safe to auto-approve since none of them write a file; leave pdf_merge, pdf_split, pdf_stamp and the rest behind a click, since each one creates a new file on disk.
| You say | Tool |
|---|---|
| Stamp PAID on this invoice and save a copy. | pdf_stamp |
| Join these three PDFs into one file. | pdf_merge |
| Split the scan: pages 1-3 are the invoice, 4 onwards is the receipt. | pdf_split |
The worked run stamped PAID on a 1-page invoice and wrote a new 0.9 MB file; the original file was byte-for-byte unchanged, which every writing tool here guarantees on purpose.
The file is mcp.json, and the key inside it is mcpServers.
| Scope | Path |
|---|---|
| Cline CLI | ~/.cline/mcp.json |
| The editor extension | opened from the Cline panel, not by path; the documentation deliberately calls it the MCP settings JSON used by the extension |

No full-app restart. The MCP settings actions include restarting an unresponsive server if its tools do not appear.
The npm publish of @theluckystrike/mcp-pdf is pending; until then use the .mcpb bundle or a clone and build from the latest release.
There is no hosted endpoint for this one yet. MCP PDF Tools runs locally over stdio with the config above, which is also the only form in which it reads and writes files on your own disk. Three of the servers in this collection are served at https://mcp.zovo.one/mcp/<name> over MCP streamable HTTP: time-tracker, price-tracker and invoice.
Cline is the one client here with an unsafe transport default. `type` selects it, and omitting `type` falls back to the legacy sse transport, so a streamable HTTP endpoint needs it written in or you will debug a server that is fine. Local entries carry "disabled" and an "autoApprove" array.
Free: info, count and text unlimited; merge up to 5 files; edits on files up to 30 pages; the PAID and DRAFT stamp presets. Pro is $19 once, verified offline.
The CLI reads ~/.cline/mcp.json. For the extension, do not hunt for a path: MCP Servers icon, Configure tab, Configure MCP Servers. cline mcp opens a wizard, and cline config mcp --json is the non-interactive form.
Set the transport explicitly. Omitting type falls back to the legacy sse transport, so streamable HTTP needs "type": "streamableHttp" written in. It is the one default here that sends you debugging a server that works.
Approve the read-only ones and leave the writing ones behind a click: each entry carries an autoApprove array and a disabled flag.
