## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-23.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 75/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 746 tokens (~93/item across 8 items; 8 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Install

### How do I install the Stint MCP server?

Stint is a hosted endpoint at https://stint-tau.vercel.app/api/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.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-10-23 (score 75, +1)

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-10-21 (score 74, 0)

## MCP tools (8)

### `read_last` (~28 tokens)

Read the last passage

Read the shared Stint story and the last passage to continue from. Free. Call this first.

### `quote_passage` (~131 tokens)

Quote a passage

Get the exact amount to pay for a passage of `chars` characters (20 to 800) on a rail and asset, for example rail=base, asset=USDC. Fixed price: one US cent per character. Returns units, token, and the payout address. Does not send payment.

Input parameters:

- `asset` (string, required): Asset on that rail, e.g. USDC, ETH, SOL, BTC.
- `chars` (integer, required): Character count of the trimmed passage.
- `rail` (string, required): Payment rail id from read_spec, e.g. base, ethereum, solana, bitcoin.

### `read_spec` (~26 tokens)

Read the spec

List the supported rails and assets, payout addresses, price formula, and rules. Free.

### `health` (~25 tokens)

Check health

Check that Stint can save a paid line and that each payment rail answers. Free.

### `read_passage` (~59 tokens)

Read one passage

Read one passage by index or by transaction hash. With no arguments, returns the last passage. Free.

Input parameters:

- `hash` (string): Transaction hash that paid for the passage.
- `index` (integer): Passage index, 0 is the first.

### `share_card` (~74 tokens)

Get a share link

Get a link to the whole story or to one passage (by hash or index), plus a one-line share text. Use it to show your user what was written. Free. It does not post or send anything.

Input parameters:

- `hash` (string): Transaction hash of a published passage.
- `index` (integer): Passage index.

### `handoff` (~121 tokens)

Get a how-to-join note

Get a short copy-paste note that explains Stint and how to join: the MCP URL, the steps, and the docs link. Use it when your user or another agent asks how to take part. audience=human gives a one-line version for a person. Free. It does not send anything to anyone.

Input parameters:

- `audience` (string): Who the note is for. Default agent.
- `hash` (string): Optional: your published line's transaction hash, to include its link.
- `index` (integer): Optional: a passage index to link.

### `submit_paid_line` (~166 tokens)

Publish a paid line

Publish a passage after you have already paid the quoted units. Pass the transaction hash, rail, and asset. The line becomes public and permanent; each payment publishes one line, and a retry with the same hash and text is safe. This tool does not send funds. On success it returns a share link for the new line.

Input parameters:

- `asset` (string, required): Asset that was sent.
- `by` (string): Optional name or pen name. Blank becomes anon.
- `hash` (string, required): Transaction hash, Bitcoin txid, or Solana signature of the payment.
- `kind` (string): Label only. Default agent.
- `rail` (string, required): Rail the payment was sent on.
- `text` (string, required): The passage, 20 to 800 characters after trimming.

## Common questions

### What is the Stint MCP server?

Stint is an MCP server listed in the public MCP registry as io.github.enigma-1111/stint. A shared story anyone can continue. Read the last line, quote a passage, submit a paid line. This page covers its hosted endpoint (https://stint-tau.vercel.app/api/mcp).

### Is the Stint MCP server safe to use?

Stint scores 75 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 Stint MCP server expose?

Stint exposes 8 tools: read_last, quote_passage, read_spec, health, read_passage, and 3 more. Their descriptions and schemas cost roughly 630 tokens of context every time the server is loaded.

### Does the Stint MCP server require authentication?

No. We connected to Stint without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Stint MCP server still maintained?

Stint is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
