naxytra MCP server

Which MCP servers are naxytra's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is

Registry namecom.naxytra/xytara-mcp-executorverified in the MCP registry

The registry name sits under naxytra.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-22 the server answered initialize and tools/list without a sign-in. First answer in 138 ms.

Should an agent connect itConnect it

Its tools do every use case we checked: Check whether an x402 payment actually settled; Encode and decode ABI call data; Extract plain text from HTML pages.

Once connected

For "Check whether an x402 payment actually settled", the likely first call is x402.verify-receipt.
For "Encode and decode ABI call data", the likely first call is abi.encode.
For "Extract plain text from HTML pages", the likely first call is html.to-text.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

summarize
Extractive summary: returns the first sentences of the text (default 3, up to 10) capped at max_chars (default 600, 50-2000), taken from the first 4000 characters. Deterministic; it does not paraphrase. `truncated` is true when the source…
zones.lookup
Live DNS lookup of A, AAAA, CNAME, MX, NS and TXT records for a domain (a URL is accepted; its hostname is used; IDNs are punycoded). 2 s per query, ~5 s total. Per-record errors are reported in record_errors; if no record resolves at all…
catalog
Lists the enabled tools with titles, descriptions and the price. Same information as tools/list. Free: never requires payment.
reply.draft
Builds a structured reply to a message: greeting to the sender (name detected from the sign-off, or sender_name), acknowledgement, every question and request found in the message listed with an answer placeholder, deadlines noted, and a…
json.validate
Validates a JSON payload (any JSON value, or JSON text as a string) against a JSON Schema and returns valid plus every error with its JSON Pointer path. Supported keywords: type, required, properties, additionalProperties…
text.extract
Extracts emails, URLs (trailing punctuation stripped), IPv4 addresses, EVM addresses, transaction hashes, @mentions, #hashtags, prices, ISO/slash dates and phone numbers (dates, IPs and plain numbers are not reported as phones). Input up…
html.to-text
Converts HTML to readable plain text: drops scripts/styles/comments and all attribute text, keeps paragraph and list structure, separates table cells with " | ", decodes numeric and common named entities, and returns the <title>…
text.chunk
Splits text into chunks of at most max_chars (100-20000, default 2000) preferring paragraph, line, sentence and word boundaries, with optional overlap (up to half of max_chars). Sizes are UTF-16 code units; surrogate pairs (emoji) are…
x402.decode
Decodes an x402 payment challenge (base64 PAYMENT-REQUIRED header, or the JSON; v2 `amount` and v1 `maxAmountRequired`) into networks, assets, human amounts and payTo. A challenge with no payment options fails (not charged). Price: $0.01…
keccak256
Ethereum keccak256 of the input: returns the 32-byte digest and the 4-byte selector. encoding auto (default) hashes 0x-hex input as bytes and anything else as UTF-8 text; force utf8 or hex explicitly. The empty string is allowed. Up to…
address.validate
Checks an EVM address: format (0x + 40 hex), EIP-55 checksum (for mixed-case input), zero address, and returns the checksummed form. Price: $0.01 USDC per call on Base mainnet ($0.001 on Base Sepolia), paid with x402; failed calls are not…
x402.verify-receipt
Decodes an x402 PAYMENT-RESPONSE receipt and checks Base / Base Sepolia: settlement_confirmed is true only if the tx succeeded and its logs contain a USDC Transfer to the expected payTo (pay_to, else this server's) for the expected amount…
tx.status
Looks up a transaction by hash on Base mainnet (default) or Base Sepolia: success/failed/pending, block, confirmations, from, to, value and gas. network accepts eip155:8453, base, 8453, eip155:84532, base-sepolia, 84532. A hash unknown to…
abi.encode
Solidity ABI encoding (like abi.encode): address, bool, uint8-256, int8-256, bytes1-32, bytes, string, dynamic T[] and fixed T[k] arrays, and tuples written (uint256,address), nested to any depth. Strict: exact 20-byte (checksum-valid)…
abi.decode
Decodes ABI-encoded hex for the given types (same type support as abi.encode). Strict: every length and offset is bounded by the data present, dirty padding bits and trailing bytes are rejected, and calldata with a 4-byte selector is…
merkle.verify
Verifies a keccak256 Merkle proof. leaf, root and every proof entry must be 0x 32-byte hashes (hash_leaf:true keccak-hashes a raw leaf first). sorted:true (default) is OpenZeppelin MerkleProof (sorted pairs); sorted:false needs leaf_index…
eip712.hash
Computes the EIP-712 digest, domain separator, struct hash and encodeType from domain, types, primaryType and message (what wallets sign, including the x402 USDC TransferWithAuthorization). Every field is type-checked; a missing field…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "xytara-mcp-executor": {
      "type": "http",
      "url": "https://xytara-mcp-executor.onrender.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http naxytra https://xytara-mcp-executor.onrender.com/mcp

Add to Cursor Add to VS Code

claude.ai, ChatGPT and other clients: add https://xytara-mcp-executor.onrender.com/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
