What it can do

  • Base64 Decode: Decode a Base64 string into UTF-8 text and report invalid payloads as errors when recovering embedded credentials, tokens, or transport-encoded content.
  • Base64 Encode: Convert a UTF-8 string into standard Base64 when you need a portable text encoding for credentials, binary-safe transport, or embedding data in JSON/HTTP fields.
  • Countries Bulk: Download the complete versioned countries dataset as JSON for caching, offline use, or multi-country analysis when a single country_lookup call is not enough.

How to connect

How to connect Agent Bits to Claude

The server address to paste into Claude settings:

https://agentbits--smithery-miwy.run.tools

  1. Open Claude (claude.ai or the desktop app).
  2. Go to Settings → Connectors.
  3. Click Add custom connector.
  4. Paste the server address copied below into Remote MCP server URL and click Add.
  5. In a chat, click + → Connectors and switch the new connector on.

Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

Authorization

After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

How to connect Agent Bits to ChatGPT

The server address to paste into ChatGPT settings:

https://agentbits--smithery-miwy.run.tools

  1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
  2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
  3. Open Settings → Connectors and click Create.
  4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
  5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
  6. In a new chat open + → Apps/Connectors and enable the connector.

OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

Authorization

On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

How to connect Agent Bits to Cursor

The server address to paste into Cursor settings:

https://agentbits--smithery-miwy.run.tools

Fastest: click Open in Cursor below and confirm the prompt.

Manually:

  1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
  2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
  3. Save the file. The server appears in the MCP list; authorize it there if asked.

Authorization

If the service needs sign-in, an authorize button appears next to the server in the MCP list.

Server tool list (18)

base64_decodeDecode a Base64 string into UTF-8 text and report invalid payloads as errors when recovering embedded credentials, tokens, or transport-encoded content.
base64_encodeConvert a UTF-8 string into standard Base64 when you need a portable text encoding for credentials, binary-safe transport, or embedding data in JSON/HTTP fields.
countries_bulkDownload the complete versioned countries dataset as JSON for caching, offline use, or multi-country analysis when a single country_lookup call is not enough.
country_lookupResolve an ISO 3166-1 alpha-2 country code (for example CA, US, JP) to official name, region, currency, calling code, languages, and related country metadata when you already have the two-letter code.
currency_lookupResolve an ISO 4217 currency code such as USD, EUR, or JPY to its name, symbol, decimal places, and which countries use it when you need currency metadata rather than a live exchange rate.
http_status_lookupExplain what a numeric HTTP status code such as 404 or 429 means by returning its standard reason phrase and a short description for debugging or API responses.
isbn_validateVerify whether an ISBN-10 or ISBN-13 passes checksum rules and return normalized digits when checking book identifiers before catalog or purchase flows.
json_validateParse a string as JSON to confirm it is well-formed and return a normalized representation when possible before further processing or storage.
language_lookupResolve an ISO 639-1 language code such as en, fr, or ja to its English name and native name when you need language metadata from a two-letter code.
luhn_validateRun the Luhn checksum on a numeric string such as a payment-card-like identifier to verify the check digit before accepting or storing the value.
mime_lookupMap a file extension such as webp or png, or a MIME type string, to curated Content-Type metadata when setting headers, validating uploads, or choosing a media type.
timestamp_convertConvert Unix epoch seconds or milliseconds to ISO-8601, or an ISO-8601 datetime to Unix epoch values, when bridging APIs that disagree on time formats.
timezone_convertConvert an ISO-8601 datetime from one IANA timezone to another while preserving the same instant, including daylight-saving-aware wall times such as Toronto to Tokyo.
tld_lookupIdentify what a DNS top-level domain such as com, io, or ai is classified as and commonly used for when classifying domains or answering TLD questions.
unit_convertConvert a numeric value between supported length, mass, or temperature units—for example miles to kilometers or Celsius to Fahrenheit—when you need a deterministic unit conversion.
url_decodeDecode a percent-encoded URL component into plain text when reading query parameters, path segments, or form values that contain escaped characters.
url_encodeApply encodeURIComponent-style percent-encoding so query parameters, path segments, or form values are safe to place in a URL.
uuid_validateCheck whether a string is a well-formed UUID and, when recognizable, report its version and variant so you can accept or reject identifier inputs confidently.
