Overview
Base64 Encoder/Decoder works by converting text to Base64 encoding or decoding Base64 strings back to readable text. Returns the converted result along with length information.

The tool
Once your client is connected to the VerveKit server, this appears in its tool list as Base64EncodeDecodeSkill. It is read-only and open-world — it fetches and never mutates anything on your side — so most clients call it without asking you to confirm.
{
"name": "Base64EncodeDecodeSkill",
"arguments": {
"text": "Hello World"
}
}You do not name the tool yourself; the model picks it. Asking about Hello World in the terms this skill covers is enough for it to reach for Base64EncodeDecodeSkill on its own — naming it explicitly also works, and is the way to force the call.
Connecting
One server URL covers every skill in the catalog, including this one. Authorization is OAuth: the client opens a browser once, and there is no key to paste into a config file.

"mcpServers": {
"vervekit": {
"url": "https://api.vervekit.com/v1/mcp"
}

Arguments
These are the properties on the tool's inputSchema, so a well-behaved client validates them before the call is made. Premium arguments are accepted on every plan but only take effect on plans that include them.
| Argument | Type | Description |
|---|---|---|
textRequired | string | The text to encode |
actionOptional | string | The action to performencodedecodedefault encode |
What the model gets back
The result carries a structuredContent object matching the tool's declared outputSchema, so a client reads fields without parsing prose. status is "ok" and error is null on success; a null field means the value was not available for that input, not that the call failed.
{
"status": "ok",
"error": null,
"data": {
"action": "encode",
"original": "Hello World",
"encoded": "SGVsbG8gV29ybGQ=",
"length": 16
}
}
Response fields
Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.
| Field | Type | Example | Description |
|---|---|---|---|
action | string | encode | The action performed on the text |
original | string | Hello World | The original Base64 encoded string input |
encoded | string | SGVsbG8gV29ybGQ= | The Base64 encoded result of the input text |
length | number | 16 | Length of the decoded text |
Failure modes
Errors come back as tool errors carrying a sentence the model can act on, not a bare status code. Error handling covers the full list.
| Status | What it means |
|---|---|
400 / 422 | The arguments did not validate. The message names the offending one. |
401 | The OAuth session is invalid or expired — reconnect the server. |
403 | Blocked by a key restriction or an IP allow-list. Never a bad identity. |
404 | This skill is not part of VerveKit. Check the catalog. |
429 | Out of credits, or a brief rate limit. The message tells them apart. |
A call costs 2 credits each time the tool actually runs; a model that reasons about the tool without calling it costs nothing.
Use cases
- Data Transmission
- Encode binary data as Base64 for safe transmission over text-based protocols like email or HTTP
- API Integration
- Encode credentials or sensitive data in Base64 format for API authentication headers
- File Embedding
- Encode images or files as Base64 strings to embed them directly in HTML, CSS, or JSON
- Data Storage
- Convert binary data to Base64 for storage in text-based databases or configuration files
Other ways to use Base64 Encode/Decode Skill
Set up Base64 Encode/Decode Skill on VerveKit, or reach the same source a different way. Your VerveKit account and credits work on all of them — one key, one balance.
