## 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**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 1 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - 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**: 69/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 963 tokens (~192/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**: 7/100
  - Stability check failed: schema churn in the 9 days we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 1 additions.
- **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**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

### 2026-10-27 (score 59)

First indexed and scored.

## MCP tools (5)

### `wafermap_resources` (~217 tokens)

Search the Wafermap catalog

Lists Wafermap's pay-per-call resources (38 of its own) and the live Inference Marketplace listings (ids "m/<name>", run and paid directly to their seller, provider "community") with id, name, category, USD price and a one-line summary. Use it first to find the right resource id; then read its input schema with wafermap_resource_schema and run it with wafermap_call. Categories: LLMs, image generation, audio (speech and transcription), vision, web (reading and translation), on-chain data on Robinhood Chain and Base, tokenized stocks, Polymarket prediction markets, content tools, and workflows (several resources in one paid call: token due diligence, stock token brief, launch scan). Free, no payment needed.

Input parameters:

- `category` (string): Optional category filter.
- `query` (string): Optional words to match against the id, name, summary and tags, e.g. "stock", "image", "polymarket". Omit to list everything.

### `wafermap_resource_schema` (~106 tokens)

Get one resource's input schema

Returns everything needed to call one Wafermap resource: its USD price, the JSON Schema of its input, a ready-to-use example input, what it returns, and its HTTP endpoint. Use it after wafermap_resources and before wafermap_call so the input is valid (invalid input is rejected before any payment). Free, no payment needed.

Input parameters:

- `id` (string, required): Resource id from wafermap_resources, e.g. "stock-signal" or "prediction-markets".

### `wafermap_call` (~254 tokens)

Run a paid resource (x402)

Runs one Wafermap resource and pays its exact USD price over x402, in USDG on Robinhood Chain or USDC on Solana, Base, Arbitrum or Polygon. Send a signed x402 v2 PaymentPayload in params._meta["x402/payment"]; without it the tool returns isError with the payment requirements (price, networks, payTo) to sign. The work runs before the payment settles, so failed calls are never charged; a successful call returns the result plus a receipt with the transaction hash in _meta["x402/payment-response"]. Agents without an x402 wallet can use the Wafermap CLI (`wafermap mcp`), which pays automatically within spending caps.

Input parameters:

- `input` (object): Input object matching the resource's schema from wafermap_resource_schema, e.g. {"network":"base"}.
- `payer` (string): Optional: the EVM wallet that will sign the payment. A wallet holding 100,000 $WAFERMAP on Robinhood Chain is quoted 50% less for Wafermap's own resources (checked again against the signer).
- `resource` (string, required): Resource id from wafermap_resources, e.g. "gas-now".

### `wafermap_discover` (~163 tokens)

Find third-party x402 services

Searches the open x402 Bazaar index (run by Coinbase CDP) for paid APIs outside Wafermap's own catalog, such as weather, web search, data enrichment or token prices. Returns each service's URL, HTTP method, price, accepted networks, an example input and whether Wafermap can pay it (payable = accepts USDG on Robinhood Chain or USDC on Solana, Base, Arbitrum or Polygon). Use it when no Wafermap resource fits the task. Free, no payment needed.

Input parameters:

- `limit` (integer): How many services to return (default 10, max 20).
- `query` (string, required): What you need in a few words, e.g. "weather forecast" or "web search".

### `wafermap_tokens` (~130 tokens)

List swappable tokens

Lists the tokens a Wafermap wallet can swap through the KyberSwap aggregator on one network, with symbol, name and contract address. On Robinhood Chain this includes ETH, WETH, USDG and every Robinhood stock token (TSLA, NVDA, AAPL…); on Base it includes ETH, WETH and USDC. Use it to resolve a ticker to its contract address before quoting or executing a swap with the Wafermap CLI. Read-only and free; it does not trade.

Input parameters:

- `network` (string): Which chain's tokens to list. Defaults to robinhood.

## Common questions

### What is the Wafermap MCP server?

Wafermap is an MCP server listed in the public MCP registry as xyz.wafermap/wafermap. x402 layer for AI agents: 35 pay-per-call resources, x402 service discovery, USDG/USDC. This page covers its hosted endpoint (https://wafermap.xyz/mcp).

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

Wafermap scores 63 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 Wafermap MCP server expose?

Wafermap exposes 5 tools: wafermap_resources, wafermap_resource_schema, wafermap_call, wafermap_discover, wafermap_tokens. Their descriptions and schemas cost roughly 870 tokens of context every time the server is loaded.

### Does the Wafermap MCP server require authentication?

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

### Is the Wafermap MCP server still maintained?

Wafermap 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.
