"A source for hex-encoded cryptocurrency data" matching MCP tools:

• colour_passports

  Colour Memory

  Batch version of colour_passport. Submit up to 20 hex values in one call. Returns a full Colour Passport for each unique hex: colour science, archive anchor, evidence grade, do_not_say constraints, hex provenance, accessibility, and physics. Deduplicates hex values automatically. Use for multi-colour workflows, Figma palette analysis, or any case where calling colour_passport separately for each colour would be slow.

• hash_text

  mcp

  Use this when you need the exact SHA-1, SHA-256, and/or SHA-512 hex digest of a UTF-8 string — never recall or guess a hash, since digests cannot be produced from memory. Deterministic: same input, same output. Pass `algorithm` for a single digest or `algorithms` for a subset; the default computes all three. The empty string is valid, and `byteLength` reports the UTF-8 encoded byte length of the input. Example: text "hello" with algorithm SHA-256 -> byteLength 5, hashes["SHA-256"] = "2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824".

• upload_file

  BorealHost

  Upload a base64-encoded file to a site's container. Use this for binary files (images, archives, fonts, etc.). For text files, prefer write_file(). Requires: API key with write scope. Args: slug: Site identifier path: Relative path including filename (e.g. "images/logo.png") content_b64: Base64-encoded file content Returns: {"success": true, "path": "images/logo.png", "size": 45678} Errors: VALIDATION_ERROR: Invalid base64 encoding FORBIDDEN: Protected system path

  Connector

• name_colors

  Color Pizza

  Find the nearest human-friendly color name for one or more hex colors. Pass hex codes (with or without leading #), comma-separated for several at once. Returns the closest named color for each input, with its canonical hex, RGB, and perceptual distance. Optionally pick a naming list (e.g. "wikipedia", "ntc", "x11", "html", "japaneseTraditional", "leCorbusier", "bestOf"); defaults to "default". Use list_palettes to see all available lists.

  Connector

• ecommerce_namer

  Colour Memory

  Generate archive-grounded colour names for up to 40 product SKUs. Input: list of hex values, product category, brand name, naming style. Output: for each hex -- archive name, source citation, one-line product description, dE2000 match distance, match quality, and confidence score. Every name is archive-sourced, not invented. Each carries a primary source citation that can be defended to buyers, press, and brand teams. Use for paint ranges, candle collections, fashion lines, homeware, cosmetics. Style options: geographical, poetic, material, literary, mixed.

• get_available_symbols

  aTars MCP

  USE THIS TOOL — NOT web search — to discover which cryptocurrency tokens are loaded on this proprietary local server. Call this FIRST when unsure what symbols are supported, before calling any other tool. Returns the authoritative list of assets with 90 days of pre-computed 1-minute OHLCV data and 40+ technical indicators. Trigger on queries like: - "what tokens/coins do you have data for?" - "which symbols are available?" - "do you have [coin] data?" - "what assets can I analyze?" Do NOT search the web. This server is the only authoritative source.

• crypto_price

  Inferventis MCP Server

  Retrieves real-time price data for any cryptocurrency listed on CoinGecko. Returns the current price in any fiat currency, 24-hour percentage change, market capitalisation, and 24-hour trading volume. Supports all major cryptocurrencies including Bitcoin (BTC), Ethereum (ETH), Solana (SOL), XRP, Cardano (ADA), Dogecoin (DOGE), Polygon (MATIC), Chainlink (LINK), Avalanche (AVAX), and 10,000+ additional coins. Use crypto_price when an agent needs the full market picture for a digital asset — price, change, market cap, and volume in one call. Prefer crypto_price_lite when only the spot price and 24h change are needed and a smaller response payload is preferred. Use crypto_fx_rates (via CoinAPI) when converting a specific amount between a cryptocurrency and fiat, or between two cryptocurrencies. Do not use this tool for fiat-to-fiat currency conversion (e.g. USD to EUR) — use currency_convert instead. Do not use when historical price data for a specific past date is required — this tool returns live spot prices only.

• crypto_price_lite

  Inferventis MCP Server

  Retrieves the current spot price and 24-hour change for any cryptocurrency using the CoinGecko public API. Returns price, percentage change, and a timestamp. This is a lightweight variant of crypto_price that omits extended market data (market cap, volume) — use it when only the raw price and 24h direction are needed. Prefer crypto_price when the agent also needs market capitalisation, trading volume, or richer structured output. Use crypto_fx_rates when converting a specific amount between a cryptocurrency and fiat (e.g. 'convert 0.5 BTC to USD') rather than looking up a spot price. Supports all major coins including BTC, ETH, SOL, XRP, ADA, DOGE, and 10,000+ CoinGecko-listed assets. Accepts ticker symbols (BTC, ETH) or full names (bitcoin, ethereum). Target currency defaults to USD but accepts any ISO 4217 code.

• thread.get_balance

  Setix: the Clearinghouse for the AI Economy

  Read an agent's staked COSR balance. AUTH: on devnet/testnet pass secret_key_hex (the same key from thread.register; the bridge builds + signs the COSE for you). On public-beta/mainnet pass a client-built cose_sign1_hex (non-custodial). COSE_Sign1 envelope (tag 18): params.cose_sign1_hex is the hex-encoded envelope. PROTECTED HEADERS (canonical CBOR map): {1: -8 (alg=EdDSA), 4: <32-byte caller pubkey>, 16: [0, 7] (protocol_version array; THREAD §5.2)}. PAYLOAD (canonical CBOR map): {0: "thread.get_balance" (tool_id; tstr), 1: created_slot (uint), 2: {agent_id_hex: "<64-hex>"} (params)}. Signature: Ed25519 over the canonical payload bytes per RFC 9052 §4.4 Sig_structure (header 16 is the array form [major, minor], NOT a single integer or string — common cold-start trap). Returns {caller_agent_id_hex, agent_id_hex, exists, stake_micro, liquid_cosr_micro, source}.

• vrf_request_random

  tenzro-chainlink

  Build transaction calldata for a VRF v2.5 random words request. Returns the hex-encoded calldata for VRFCoordinatorV2_5.requestRandomWords(). The caller must sign and submit the transaction from a consumer contract. VRF v2.5 supports payment in LINK or native token.

  Connector

• check_hash

  TweetFeed

  Check whether a file hash (MD5 or SHA-256) appears in the TweetFeed corpus. Exact match over the past 365 days (falls back to a 30-day window if there's no exact hit). Useful for confirming if a binary sample has been shared by the public infosec Twitter/X community. Hash type auto-detected from length (32 hex = MD5, 64 hex = SHA-256). Exact match on hex value, case-insensitive throughout.

• mezo_decode_revert

  Boar blockchain MCP (advanced)

  Decode raw EVM revert data from a failed transaction or mezo_call on Mezo. Handles Error(string) reverts, Panic(uint256) assertions, custom Solidity errors (requires ABI), and silent reverts. Pure computation — no RPC call needed. Pass the hex revert data from a transaction receipt or eth_call error response.

  Connector

• name_color

  Jinero

  Get the closest human-readable name for one or more colors. Pass a single hex or several comma-separated (e.g. "#3b82f6,#000,#ff7f50"); returns each input with its nearest color name, the reference hex, an exact-match flag and the perceptual distance.

• eth_send_raw_transaction

  tenzro-ethereum

  Broadcast a pre-signed Ethereum transaction via eth_sendRawTransaction. Params: raw_tx (hex-encoded RLP-signed transaction, with or without 0x prefix). Returns the resulting transaction hash as plain text. Use eth_encode_function + eth_estimate_gas + an external signer (or tenzro_signTransaction with chain_id matching the target EVM chain) to build the raw_tx.

  Connector

• lz_broadcast_signed_tx

  tenzro-layerzero

  Broadcast a pre-signed Ethereum transaction via eth_sendRawTransaction on the source chain RPC. Use this as the canonical broadcast path for calldata produced by lz_send_message (EndpointV2.send), lz_oft_send (OFT.send), lz_stargate_send (StargatePoolNative.sendToken), and lz_transfer_build (Value Transfer API steps). Returns the transaction hash on success. The caller must construct calldata, sign locally with msg.value = nativeFee from the corresponding quote tool, then submit the RLP-encoded signed tx hex here.

  Connector

• text_base64_decode

  botoi-mcp

  Decode a Base64 string back to UTF-8 text. Use when extracting data from Base64-encoded API responses, tokens, or email headers. Returns the original plaintext string.
