Encode/decode base64 and URL-safe base64. x402 micropayment.
Most developer tooling work still happens through a UI a human drives. Base64 Codec API MCP server moves it into the conversation instead. Encode/decode base64 and URL-safe base64. x402 micropayment.
Encode text to base64 or decode base64 to text. Supports standard and URL-safe variants with metadata. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
The server publishes 1 tool. What each one is for:
utility_encode_base64 — POSTSetup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Base64 Codec API's toolset — utility_encode_base64 — is a fair guide to whether it matches your workflow. It is maintained by Br0ski777; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
