## 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 2026-09-28.

- **Endpoint Security**: 51/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (delete_site).
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - 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**: 67/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1727 tokens (~191/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 53/100
  - Stability observed for 16 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 99/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 97% 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 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 10 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.

## MCP tools (9)

### `share_text` (~143 tokens)

Share text with another agent or person

Use this when another AI agent, chat session or person needs text you have: instructions, code, JSON, a prompt for another model. Uploads it as a downloadable file and returns a capability url (one GET fetches it) plus a share url and password. No account or API key needed.

Input parameters:

- `content` (string, required): The text to share
- `expires_days` (integer): Days until the file is deleted (1-180, default 30)
- `filename` (string): File name for the download, e.g. instructions.md
- `password` (string): Optional custom password (8-64 chars); a strong one is generated when omitted

### `share_file` (~176 tokens)

Share one or more files with another agent

Use this when another AI agent (a different machine, model or chat session) or a person needs access to one or more files. Accepts text or base64-encoded binary content; multiple files are zipped into one bundle server-side, so a whole handoff (instructions plus code plus data) travels as one capability url. For large files already on local disk, prefer the HTTP API (one curl command, up to 2 TB): https://upload.83blue.com/docs

Input parameters:

- `bundle_name` (string): Zip name used when more than one file is sent
- `expires_days` (integer): Days until the file is deleted (1-180, default 30)
- `files` (array, required)
- `password` (string): Optional custom password (8-64 chars); a strong one is generated when omitted

### `share_conversation` (~226 tokens)

Hand a whole conversation to another model

Use this to hand your full working context to another AI: any provider, any model, any chat client. Packages a markdown transcript (instructions, conversation summary, task state) as HANDOFF.md at the root of a zip bundle together with any files, and returns a single handoff url. The receiving model just fetches that url: it gets a briefing, the file manifest and download commands in one go. Say to the next agent: "Fetch this url to pick up where I left off."

Input parameters:

- `expires_days` (integer): Days until the file is deleted (1-180, default 30)
- `files` (array): Optional files the next agent needs alongside the transcript
- `password` (string): Optional custom password (8-64 chars); a strong one is generated when omitted
- `title` (string): Short name for the bundle, e.g. "auth refactor handoff"
- `transcript` (string, required): Markdown briefing for the next agent: context, instructions, conversation summary, task state. Becomes HANDOFF.md at the bundle root.

### `receive_file` (~177 tokens)

Receive a file another agent shared

Use this when you have been given an 83blue link and need the file. Accepts a capability url (https://upload.83blue.com/f/...) on its own, or a share url plus password. Returns metadata including sha256, the file list for zip bundles, and the content inline when it is text within max_inline_bytes; otherwise returns a ready-made curl command to save the file locally.

Input parameters:

- `max_inline_bytes` (integer): Inline text content up to this many bytes (max 1000000)
- `password` (string): Needed for share urls and bare tokens; not needed for capability urls
- `url_or_token` (string, required): Capability url (https://upload.83blue.com/f/TOKEN/KEY), share url (https://upload.83blue.com/d/TOKEN), or the bare token

### `deploy_site` (~346 tokens)

Publish a static website to a live public url

Use this to put a static website you have built (HTML, CSS, JS, images, fonts) onto the public web in one call, with no signup, no account and no config. Give it the files (there must be an index.html at the root) and it returns a live https url, e.g. https://upload.83blue.com/s/brave-otter-482/, plus a manage_key you can reuse to update or delete it. Ideal when a person asks you to build them a website, landing page, demo, prototype or report and wants to see it live. IMPORTANT: the site is served from a subfolder, so use RELATIVE asset paths only (href="style.css", src="img/logo.png"), never root-absolute paths like "/style.css" which would break. Sites are served as pure static files (server-side code is never executed) and auto-expire after 30 days unless renewed. Each file is text or base64. Total site up to 50 MB, 300 files.

Input parameters:

- `expires_days` (integer): Days until the site is removed (1-30, default 30)
- `files` (array, required): The site files. Must include an index.html at the root.
- `manage_key` (string): Pass the manage_key from a previous deploy together with the same slug to update that site in place.
- `slug` (string): Optional name for the site path (3-40 chars, a-z 0-9 and hyphens); it becomes /s/{name}/. A friendly one is generated when omitted.
- `title` (string): Optional short label for your own reference

### `list_sites` (~58 tokens)

Look up a hosted site

Return the status, address, size and expiry of a site you deployed. Pass the url, host or slug.

Input parameters:

- `site` (string, required): The site url (https://.../s/name/), path (/s/name) or bare name

### `delete_site` (~63 tokens)

Take down a hosted site

Remove a site you deployed. Needs the site url/host/slug and its manage_key (returned by deploy_site).

Input parameters:

- `manage_key` (string, required): The manage_key returned when the site was deployed
- `site` (string, required): The site url, host or slug

### `remember` (~165 tokens)

Remember text, notes or JSON for a future session (durable agent memory)

Durable cross-session memory for AI agents: store notes, context, text or JSON now and recall it in a later session or from another machine by url. A free cloud scratchpad and shared key-value store for agents, no signup, no account, no API key. Also callable as save_memory, store_memory, save_note, stash. Returns a url; fetch it back later with recall.

Input parameters:

- `content` (string, required): The text or JSON to remember
- `expires_days` (integer): Days until the file is deleted (1-180, default 30)
- `filename` (string): Optional label/key for this memory, e.g. project-notes.md
- `password` (string): Optional custom password (8-64 chars); a strong one is generated when omitted

### `recall` (~130 tokens)

Recall something you stored earlier, or fetch any 83blue url

Fetch back durable memory, or any shared file/text, by its 83blue url or token (a capability url, or a share url plus password). Use this to recall what you stored with remember in an earlier session, or to download a file another agent shared. Also callable as get_memory, download_file, fetch_file, get_file.

Input parameters:

- `max_inline_bytes` (integer): Inline text content up to this many bytes
- `password` (string): Needed for share urls; not needed for capability urls
- `url_or_token` (string, required): The 83blue url or token to recall or fetch
