## 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 2026-11-05.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 59/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1260 tokens (~252/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 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.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 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 Signal Desk paid tools MCP server?

## MCP tools (5)

### `render_page` (~273 tokens)

Render a web page

Renders a public web page in a real headless browser (JavaScript runs, redirects are followed) and returns it as clean markdown, a PNG screenshot or a PDF. One call, one payment, no account. A render that fails is not charged. Price: $0.01 per call in USDC (x402).

Input parameters:

- `format` (string): markdown: the page's main content as text. screenshot: a PNG image. pdf: a PDF document.

### `host_file` (~206 tokens)

Host a file

Hosts a file: upload up to 10 MB as base64 with its content type and get back a public download URL that serves the bytes with that content type for 1 to 168 hours (default 24). Downloads are free, readable at once where uploaded and everywhere within about a minute. Executables are refused; HTML and SVG are served as attachments. A failed upload is not charged. Price: $0.01 per call in USDC (x402).

Input parameters:

- `contentType` (string, required): MIME type the file is served with, e.g. image/png or application/pdf. Executable types are refused; text/html and image/svg+xml are served as attachments.

- `filename` (string): Suggested download name. Never used as the storage key.
- `ttlHours` (integer): Hours the download URL keeps working, default 24.

### `schedule_callback` (~301 tokens)

Schedule a callback

Schedules a delayed HTTP callback: give a public URL, an optional JSON body, optional headers and a delay of 60 seconds to 7 days (or an absolute time), and the URL is called at that time (POST when a body was given, otherwise GET), with one retry and a 10-second timeout. The answer carries a free status URL that reports whether it fired and what the callee answered. A request that is refused is not charged. Price: $0.005 per call in USDC (x402).

Input parameters:

- `delaySeconds` (integer): Seconds from now, 60 to 604800. Give this or at, not both.
- `headers` (object): Extra request headers, up to 16, printable ASCII values up to 1024 characters. host, content-length and connection-level headers are refused.
- `url` (string, required): Public http(s) URL to call. Private, local and cloud-metadata addresses are refused, when scheduled and again when fired. Redirects are reported, not followed.

### `recent_launches` (~168 tokens)

Recent pump.fun launches, trend-matched

Lists pump.fun token launches from the last N minutes (decoded from Solana mainnet within about a minute), each with its creator wallet, that wallet's seven-day launch count, and, when the coin's name matches a topic currently trending on Google Trends or moving on Polymarket, the matched trend with its source and score.

Trending topics, cross-source

Lists topics trending right now across Google Trends (US realtime) and Polymarket (markets moving on volume), merged by topic, strongest first, each with score, score velocity per hour, first and last seen times, a type label (person, brand, event, place, meme, other), the headlines or market numbers behind it, and how many pump.fun launches in the last hour match it. Sources are polled every five minutes. Price: $0.01 per call in USDC (x402).

Input parameters:

- `hours` (integer): Topics seen within this many hours (default 6).
- `limit` (integer): Strongest first (default 25).
- `minScore` (integer): Drop topics below this score.

## Common questions

### What is the Signal Desk paid tools MCP server?

Signal Desk paid tools is an MCP server listed in the public MCP registry as io.github.huntercarver24/signal-desk. x402-paid tools: render pages, host files, delayed callbacks, pump.fun launch feed, trend radar. This page covers its hosted endpoint (https://x402-mcp.huntercarver24.workers.dev/mcp).

### Is the Signal Desk paid tools MCP server safe to use?

Signal Desk paid tools scores 68 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 Signal Desk paid tools MCP server expose?

Signal Desk paid tools exposes 5 tools: render_page, host_file, schedule_callback, recent_launches, trending_topics. Their descriptions and schemas cost roughly 1,116 tokens of context every time the server is loaded.

### Does the Signal Desk paid tools MCP server require authentication?

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

### Is the Signal Desk paid tools MCP server still maintained?

Signal Desk paid tools is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the Signal Desk paid tools MCP server?

VerifyMCP ran 12 checks on Signal Desk paid tools, covering TLS certificate, Authorization, HSTS header, DNSSEC and 8 more. One item could not be completed, a gap on our side rather than a finding about Signal Desk paid tools: HTTPS. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
