How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability57
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 955 tokens (~191/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management7
- Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage85
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 56% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

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 →
pdf_batch Batch-edit a PDF template ~233
Apply the same edits to one template PDF once per record, producing one output document per record — a mail merge over an existing PDF. Returns a `job_id`: call `pdf_job` with it for the per-record results. To change text on one page only, set `scope.pages`; to pick one of several identical matches, use `scope.after` with nearby text or `scope.occurrence`. Use `op: 'redact'` when the text must be unrecoverable.
| Name | Type | Req | Description |
|---|---|---|---|
| edits | array | yes | The edits applied to each record, with `{field}` placeholders filled from it. |
| file | string | yes | The PDF: an absolute (or ~) local path, which this server uploads for you, an https:// URL the API fetches, or an `f_…` file id from an earlier call. Used as the template for every record. |
| options | object | – | – |
| password | string | – | – |
| records | array | – | One object per output document. |
| records_url | string | – | A CSV or JSONL file of records, instead of `records`. |
No output schema declared.
No examples provided.
pdf_edit Edit a PDF ~271
Edit the text of an existing PDF in place: replace, delete, redact, insert, or fill form fields, keeping the original layout, fonts and everything you did not point at. `edits[]` is taken exactly as the API takes it (`op`, `scope`, `match`, `fit`), and the result carries up to 3 before/after previews of the pages that changed. To change text on one page only, set `scope.pages`; to pick one of several identical matches, use `scope.after` with nearby text or `scope.occurrence`. Use `op: 'redact'` when the text must be unrecoverable.
| Name | Type | Req | Description |
|---|---|---|---|
| edits | array | yes | The edits to apply, in order, exactly as `POST /v1/edit` takes them. |
| file | string | yes | The PDF: an absolute (or ~) local path, which this server uploads for you, an https:// URL the API fetches, or an `f_…` file id from an earlier call. |
| options | object | – | – |
| output_path | string | – | Where to write the edited PDF (stdio mode only). Default: `<name>.edited.pdf` next to the input. |
| password | string | – | The document open password, when it has one. |
No output schema declared.
No examples provided.
pdf_find Read the text of a PDF ~214
Read the text of a PDF: every span with its page, position, font and span id, optionally filtered by `query` (the same four `match` modes an edit uses) and `pages`, over the `content`, `forms` and `annotations` layers. Paginated: pass the returned `next_cursor` back as `cursor` for the next page. Use it before `pdf_edit` to check what a document actually says and to pick the `scope` that selects the match you mean.
| Name | Type | Req | Description |
|---|---|---|---|
| cursor | string|null | – | – |
| file | string | yes | The PDF: an absolute (or ~) local path, which this server uploads for you, an https:// URL the API fetches, or an `f_…` file id from an earlier call. |
| layers | array | – | – |
| limit | integer | – | (default: 200) |
| match | object | – | – |
| pages | – | – | – |
| password | string | – | – |
| query | string|null | – | – |
No output schema declared.
No examples provided.
pdf_job Job result ~99
The result of an async edit or a batch, by `job_id`: the same body `pdf_edit` returns once the job is done, plus `progress` while it is still queued or running, and `records` for a batch.
| Name | Type | Req | Description |
|---|---|---|---|
| job_id | string | yes | The `job_id` an async edit or a batch returned. |
| output_path | string | – | Where to write the finished document (stdio mode, single-document jobs only). |
No output schema declared.
No examples provided.
pdf_preview Render a PDF page ~138
Render one page of a PDF as a PNG image block, optionally cropped to `region` and with rectangles drawn over `highlight`. Use it to see a page before editing it, or to check the result afterwards.
| Name | Type | Req | Description |
|---|---|---|---|
| file | string | yes | The PDF: an absolute (or ~) local path, which this server uploads for you, an https:// URL the API fetches, or an `f_…` file id from an earlier call. |
| highlight | – | – | – |
| page | integer | – | (default: 1) |

How do I install the io.github.zp130221/pdfedit-mcp server?
io.github.zp130221/pdfedit-mcp is a hosted endpoint at https://pdfedit-mcp-remote.niubai-pdfedit-remote-worker.workers.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Edit text inside existing PDFs: replace, delete, redact, insert, fill forms; original fonts kept. This page covers its hosted endpoint (https://pdfedit-mcp-remote.niubai-pdfedit-remote-worker.workers.dev/mcp).
Is the io.github.zp130221/pdfedit-mcp server safe to use?
io.github.zp130221/pdfedit-mcp scores 63 out of 100 on VerifyMCP. 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.zp130221/pdfedit-mcp server expose?
io.github.zp130221/pdfedit-mcp exposes 5 tools: pdf_edit, pdf_batch, pdf_find, pdf_preview, pdf_job. Their descriptions and schemas cost roughly 955 tokens of context every time the server is loaded.
Does the io.github.zp130221/pdfedit-mcp server require authentication?
No. We connected to io.github.zp130221/pdfedit-mcp without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the io.github.zp130221/pdfedit-mcp server still maintained?
io.github.zp130221/pdfedit-mcp is still listed as active in the MCP registry. We last reached this channel on 18 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
