Sample input

eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiZXhwIjoxNzAwMDAwMDAwfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c

API / MCP call

curl -X POST https://toolkit.fun/api/v1/t/jwt-decode \
  -H "Authorization: Bearer tk_..." \
  -H "Content-Type: application/json" \
  -d '{"input":"...","params":{}}'

MCP server: https://toolkit.fun/api/mcp

Shortest path for an agent

Read the manifest first, then call the same run contract used by the web UI. The input, output, permissions, and receipt stay consistent across REST and MCP.

Manifest: https://toolkit.fun/api/v1/registry/tools/jwt-decode/manifest
REST: POST https://toolkit.fun/api/v1/t/jwt-decode
MCP: https://toolkit.fun/api/mcp

Who it is for

Use this tool directly when you need JWT Decoder, want to chain it into a workflow, or want to expose it to an agent over REST API or MCP. This page carries the sample, call syntax, manifest, and version so search engines and generative retrieval can describe the tool accurately.
