How to Use the Deterministic JWT Inspector MCP in AutoGen
Give your AutoGen security agents the ability to locally decode and debate JWT structures without signature keys.
Works with every AI agent you already use
…and any MCP-compatible client
Connect Deterministic JWT Inspector MCP to AutoGen
Create your Vinkius account to connect Deterministic JWT Inspector to AutoGen and route execution through our secure gateway. The platform manages server hosting, runtime updates, and security layers. Configuration requires no manual server provisioning.
Cross-Examine Tokens in AutoGen
The `inspect_jwt` tool feeds raw, decoded token structures directly into your AutoGen multi-agent debates. One agent passes the raw string. The tool returns the unencrypted header and payload. Your security agent can then analyze the `alg` header while a separate routing agent evaluates the custom claims. Look, this creates a strict separation of concerns. You don't need to distribute public keys to every agent in the conversation. The MCP Server handles the base64 parsing, letting your agents focus entirely on arguing about whether the token's scope is too permissive.
Real-Time Expiry Audits
The `inspect_jwt` tool computes the exact time-to-live by comparing the token's `exp` claim against the current system clock. It outputs a clear validity status. If a token is expired, your AutoGen agents see that immediately and can negotiate whether to request a refresh or terminate the session. Agents need hard facts to reach consensus. By providing deterministic expiration data, this tool stops agents from hallucinating timelines. The `McpToolAdapter` automatically maps the tool's output schema so the agents understand the difference between a missing claim and an expired one.
Local Inspection MCP Server
The `inspect_jwt` tool keeps your debugging sessions off the public internet. Developers constantly leak credentials by pasting JWTs into online decoders. AutoGen runs this tool locally. Your agents inspect the tokens inside your own environment. You initialize this via `mcp_server_tools` using standard HTTP or stdio transports. The server does one thing and does it well. It blindly decodes strings. It explicitly warns your agents that the signature is unverified, ensuring your security agents factor that risk into their final consensus.
Set up Deterministic JWT Inspector MCP in AutoGen
Prerequisites
- Python 3.10+ installed
-
autogen-ext[mcp]package - Active Vinkius subscription with a valid endpoint token
- 1
Install AutoGen with MCP
Run
pip install "autogen-ext[mcp]" autogen-agentchat. The MCP extension includesmcp_server_toolsfor stateless tool access. - 2
Fetch tools from the MCP
Call
mcp_server_tools(SseServerParams(url=...))with your Vinkius endpoint. Replace[YOUR_TOKEN_HERE]with your token from cloud.vinkius.com. - 3
Run your agent
Pass the tools to
AssistantAgentand callagent.run(). The agent invokes Deterministic JWT Inspector tools and returns structured results.
from autogen_ext.tools.mcp import SseServerParams, mcp_server_tools
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient
server_params = SseServerParams(
url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
tools = await mcp_server_tools(server_params)
agent = AssistantAgent(
name="Deterministic JWT Inspector_assistant",
model_client=OpenAIChatCompletionClient(model="gpt-4o"),
tools=tools,
)
result = await agent.run("List recent Deterministic JWT Inspector data")
print(result.messages[-1].content)Prerequisites
- Python 3.10+ installed
-
autogen-ext[mcp]+autogen-agentchat - Active Vinkius subscription with a valid endpoint token
- 1
Install dependencies
Same packages as above.
McpWorkbenchis ideal when your agent needs stateful sessions across multiple tool calls. - 2
Use McpWorkbench as context manager
Wrap your agent in
async with McpWorkbench(...)to maintain shared state and resources. The workbench manages the full MCP session lifecycle. - 3
Run with workbench
Pass
workbench=workbenchto your agent. State is preserved across multiple tool calls within the same session.
from autogen_ext.tools.mcp import McpWorkbench, SseServerParams
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient
server_params = SseServerParams(
url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
async with McpWorkbench(server_params) as workbench:
agent = AssistantAgent(
name="Deterministic JWT Inspector_assistant",
model_client=OpenAIChatCompletionClient(model="gpt-4o"),
workbench=workbench,
)
result = await agent.run("List recent Deterministic JWT Inspector data")
