What changed 14

Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 7 October 2026. No other catalogue keeps this.

7 Oct 8 tool descriptions were rewritten base64_decode, base64_encode, get_credit_balance and 5 more

7 Oct 6 tools changed the parameters they ask for base64_decode, base64_encode, hash_sha256 and 3 more

Nothing serious here today

Today is the operative word: we check Hash Encoding Direct Credits every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 8

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

base64

base64_decode

Decode a standard Base64 string into UTF-8 text. Use this only when the decoded bytes are expected to be valid UTF-8; this tool is not for arbitrary binary output. Base64 is reversible encoding, not encryption. Costs 1 credit.

base64_encode

Encode UTF-8 text as standard Base64. Use this for transport/storage encoding of text bytes; Base64 is reversible encoding, not encryption and not a cryptographic hash. Returns the encoded Base64 string. Costs 1 credit.

hash

hash_sha256

Create an unkeyed SHA-256 fingerprint of UTF-8 text. Use this for checksums, deduplication, content fingerprints, or integrity comparisons when no shared secret is involved; use hmac_sha256 instead when keyed authentication is required. Returns the 32-byte digest as 64 lowercase hexadecimal characters. Costs 1 credit.

hash_sha512

Create an unkeyed SHA-512 fingerprint of UTF-8 text. Use this when a 512-bit digest is specifically required for checksums, fingerprints, or compatibility; use hash_sha256 for the more common 256-bit digest and hmac_sha256 when keyed authentication is required. Returns 128 lowercase hexadecimal characters. Costs 1 credit.

credit

get_credit_balance

Check the remaining prepaid API credits for the bearer token configured on this MCP connection. Use this after redeeming a payment when you need to decide whether a protected tool can be called. The bearer token is read from the Authorization header, not from tool arguments. This call is free, does not spend credits, and does not purchase or redeem credits.

hmac

hmac_sha256

Authenticate a UTF-8 message with a UTF-8 secret key using HMAC-SHA256. Use this when you need keyed integrity/authentication with a shared secret; use hash_sha256 instead for an unkeyed checksum or fingerprint. Returns the 32-byte HMAC as 64 lowercase hexadecimal characters. Costs 1 credit.

jwt

jwt_decode

Decode a compact JWT's header and payload for inspection without verifying its signature. Use this for debugging or reading claims only; never treat the returned claims as authenticated or trusted. The response always reports signatureVerified=false, even when a signature segment is present. Costs 1 credit.

payment

get_payment_info

Return the complete purchase and redemption instructions for this service's prepaid API credits. Use this before paying or when an agent needs the Base Mainnet network, native USDC contract, receiver address, exact package amount, credit quantity, buyer-gas requirement, or redemption steps. This call is free and does not require a bearer token. It does not return a balance; use get_credit_balance after you already have a redeemed bearer token. This payment scheme is direct USDC credits, not x402.

Hash Encoding Direct Credits — questions

Answers built from our own checks of this server.

What can Hash Encoding Direct Credits do?

It exposes 8 tools, read directly from the server on our last check. Among them: base64_decode, base64_encode, get_credit_balance, get_payment_info, hash_sha256, hash_sha512 and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Hash Encoding Direct Credits mostly used for?

Its tools cluster around hash and base64. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Hash Encoding Direct Credits working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 120 ms. The bar chart above shows every period we have measured.

How do I connect Hash Encoding Direct Credits?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Hash Encoding Direct Credits need an API key?

No. Hash Encoding Direct Credits completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Hash Encoding Direct Credits?

It answers our handshake in 120 ms on average, which is faster than 78% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
