MCP server for terminal commands, file operations, and process management
Nothing to run from here
Anvil is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Hosted MCP server for Anvil — fill & generate PDFs and run Etch e-signature packets for AI agents.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http anvil-mcp https://anvil.usefulapi.io/mcp
# 2 — ask your agent for something these tools do
# anvil_current_user, anvil_get_organization, anvil_get_cast and 7 more
Anvil costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http anvil-mcp https://anvil.usefulapi.io/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
10 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Get the authenticated Anvil user (from the API key) and the organizations they belong to (eid, name, slug). Good first call to discover org slugs/eids for other tools. GraphQL query: currentUser.
No parameter schema on file.
Fetch an Anvil organization and its PDF templates (casts) and workflows (welds). Provide either its slug or its eid (at least one is required). GraphQL query: organization.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| slug | string | no | Organization slug (from anvil_current_user). Provide this OR eid. |
| eid | string | no | Organization eid. Provide this OR slug. |
Fetch a cast — an Anvil PDF template — by its eid: title, version number, and whether it is a template. Use the returned eid as the cast_eid for anvil_fill_pdf. GraphQL query: cast.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| eid | string | yes | The cast (PDF template) eid. |
Fetch an Etch e-signature packet by eid: its status, details URL, document group, and every signer (eid, aliasId, name, email, status, routing order). Use this to check signature progress. GraphQL query: etchPacket.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| eid | string | yes | The Etch packet eid (returned by anvil_create_etch_packet). |
Fetch a weld — an Anvil workflow — by eid, including its forges (the individual form steps: eid, name, slug). GraphQL query: weld.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| eid | string | yes | The weld (workflow) eid. |
Fetch a weldData record — a single submission to a weld (workflow) — by eid: completion state, test flag, and creation time. GraphQL query: weldData.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| eid | string | yes | The weldData (workflow submission) eid. |
Fill an Anvil PDF template (cast) with data and return the finished PDF as base64. REST: POST /fill/{castEid}.pdf. Returns { filename, byteLength, pdfBase64 }. The data object's keys are the template's field aliases.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| cast_eid | string | yes | The cast (PDF template) eid to fill (from anvil_get_cast). |
| data | object | yes | Object mapping the template's field aliases to values, e.g. { "name": "Sam", "date": "2026-07-16" }. |
| title | string | no | Optional title embedded in the generated PDF metadata. |
| fontSize | number | no | Optional default font size for filled text. |
| textColor | string | no | Optional default text color as a hex string, e.g. #333333. |
Generate a brand-new PDF from HTML or Markdown and return it as base64. REST: POST /generate-pdf. For type=html, pass data = { html, css? }. For type=markdown, pass data = [ { label, content }, ... ]. Returns { filename, byteLength, pdfBase64 }.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| type | string | no | Source format. Default html. |
| data | yes | For html: { html: "<h1>Hi</h1>", css?: "..." }. For markdown: [ { label: "Section", content: "# Title ..." }, ... ]. | |
| title | string | no | Optional title embedded in the generated PDF metadata. |
Create an Etch e-signature packet (documents + signers). GraphQL mutation: createEtchPacket. IMPORTANT: isDraft defaults to true (a safe draft that sends nothing). Setting isDraft=false with real signers SENDS signature-request emails to those signers. Use isTest=true while developing.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| name | string | yes | Human-readable name for the packet. |
| signers | array | no | Array of signer objects, e.g. [{ id, name, email, signerType, routingOrder, fields }]. Passed straight through to Anvil. |
| files | array | no | Array of file/document objects (casts or uploads) to include. Passed straight through to Anvil. |
| data | object | no | Optional payload data used to pre-fill the packet's documents. |
| isDraft | boolean | no | Default true. When true, creates a draft and sends nothing. Set false to activate and email signers. |
| isTest | boolean | no | Set true to create a test packet (no legal weight, no charge). |
| signatureEmailSubject | string | no | Optional subject line for the signature-request email. |
| signatureEmailBody | string | no | Optional body text for the signature-request email. |
Generate a one-time embedded signing URL for a specific signer in an Etch packet (for iframe/redirect signing flows). GraphQL mutation: generateEtchSignURL. Returns { url }.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| signer_eid | string | yes | The signer eid (from the packet's documentGroup.signers). |
| client_user_id | string | yes | Your app's stable id for the signing user (ties the session to your user). |

ATool-list grade · score 93 / 100
Release 1.11.1 · scanned 20 Oct 2026
Graded from the tools this server lists, not from its source code.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | moderate | capability blast radius (moderate) — client exposure if the model is manipulated | −3 |
| coverage-honesty | manifest | inspection depth (manifest) — how much of the target the scan could see | −4 |
score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Anvil can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
