- Transports: `streamable-http`
- Auth: `none`
- Version: `2.1.0`

## 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 2026-09-29.

- **Endpoint Security**: 74/100
  - 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.
  - 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**: 43/100
  - 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 3195 tokens (~199/item across 16 items; 15 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 15 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 17 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (15)

### `web_read` (~233 tokens)

Read a web page (clean markdown)

Any public URL → clean readable markdown: the article/main content without nav, ads or boilerplate, plus title, author, date, word count and links. PDFs too. Fetches the page (redirects followed, public internet only), extracts the main content with Mozilla Readability and converts it to markdown. PDFs are converted to text. Use max_chars to bound the output. JavaScript-only pages return whatever the server sends (no headless browser). When to use: For a page's content; for its metadata only use web_meta; for uptime/redirects use http_probe. Price: $0.002 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns isError with a message for invalid input or an upstream failure (not charged).

Input parameters:

- `include_links` (boolean): keep hyperlinks (absolute) in the markdown and return a link list. Default false.
- `max_chars` (integer): Truncate the returned markdown to this many characters. Range 500-100000. Default 20000.
- `url` (string, required): http(s) URL

Output parameters:

- `byline` (string|null)
- `excerpt` (string|null)

### `web_meta` (~171 tokens)

Page metadata + link preview

Everything a page says about itself: title, description, OpenGraph/Twitter card, canonical, favicon, language, RSS/Atom feeds, JSON-LD schema types, headings — and link-preview problems. Use to build link previews, check SEO/social cards, find a site's feeds or structured data. Flags missing og:image, missing description and non-absolute image URLs (common reasons a link shows up bare on X/Telegram). When to use: For title/OpenGraph/canonical; for the article text use web_read. Price: $0.001 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns isError with a message for invalid input or an upstream failure (not charged).

Input parameters:

- `url` (string, required): Absolute http(s) URL of the page.

### `dns_lookup` (~164 tokens)

DNS records + email security

All DNS for a domain — A, AAAA, CNAME, MX, NS, TXT, CAA, SOA — plus SPF and DMARC parsed and graded, so an agent knows where a domain points and whether its email can be spoofed. Queried live against public resolvers (Cloudflare, Google, Quad9). Email grade: SPF present and ending in -all/~all, DMARC present with p=quarantine/reject. When to use: For DNS records; for ownership dates use domain_whois; for certificates use tls_check. Price: free. Errors: returns isError with a message for invalid input or an upstream failure (not charged).

Input parameters:

- `domain` (string, required): Domain name without scheme, e.g. "example.com".

Output parameters:

Uses RDAP, the registries' official successor to WHOIS (rdap.org bootstrap). A domain with no RDAP record and no DNS is reported as likely available. Young domains (< 30 days) are flagged: most phishing/scam sites are days old. When to use: For registration and expiry; for DNS records use dns_lookup.

One real GET from our server. The security grade counts HSTS, Content-Security-Policy, X-Frame-Options/frame-ancestors, X-Content-Type-Options, Referrer-Policy and Permissions-Policy. When to use: For availability, status and timings; for page content use web_read. Price: $0.001 per call (10 free/day; after that a payment-required result lists x402 options).

Standard robots.txt matching (longest match wins, Allow beats Disallow on ties, * and $ wildcards). Missing robots.txt = everything allowed. Price: $0.001 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns isError with a message for invalid input or an upstream failure (not charged).

## Common questions

### What is the MAD Synapse · Web & Research MCP server?

MAD Synapse · Web & Research is an MCP server listed in the public MCP registry as art.maddegen.agent/synapse-web. Read the web (page text, DNS, WHOIS, TLS, uptime) + research (Wikipedia, arXiv, GitHub, packages). This page covers its hosted endpoint (https://agent.maddegen.art/hub/mcp/web).

### Is the MAD Synapse · Web & Research MCP server safe to use?

MAD Synapse · Web & Research scores 66 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 MAD Synapse · Web & Research MCP server expose?

MAD Synapse · Web & Research exposes 15 tools: web_read, web_meta, dns_lookup, domain_whois, tls_check, and 10 more. Their descriptions and schemas cost roughly 2,722 tokens of context every time the server is loaded.

### Does the MAD Synapse · Web & Research MCP server require authentication?

No. We connected to MAD Synapse · Web & Research without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the MAD Synapse · Web & Research MCP server still maintained?

MAD Synapse · Web & Research is still listed as active in the MCP registry. We last reached this channel on 29 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
