Python: samples(mcp): add TWZRD Agent Intel trust verification concept sample

[twzrd-sol]

Summary

Adds a concept sample demonstrating how to use TWZRD Agent Intel as a remote MCP plugin in a Semantic Kernel agent for trust scoring and x402 payment verification of AI agents on Solana.

File: python/samples/concepts/mcp/agent_with_twzrd_trust_verification.py

What it shows

Uses MCPStreamableHttpPlugin (same pattern as the existing agent_with_http_mcp_plugin.py) to connect to https://intel.twzrd.xyz/mcp and provide a ChatCompletionAgent with TWZRD trust tools:

• score_agent(wallet) — returns 0-100 trust score + reputation data
• preflight_check(wallet) — pre-transaction safety check
• verify_trust_receipt(receipt) — verify x402 payment receipts

Why this fits here

The concepts/mcp/ directory already has agent_with_http_mcp_plugin.py using MCPStreamableHttpPlugin for the Microsoft Learn Docs MCP. TWZRD is another zero-install remote MCP server demonstrating the same connection pattern but for a different domain (Web3/agent trust infrastructure).

Running it

export OPENAI_API_KEY=sk-...
export OPENAI_CHAT_MODEL_ID=gpt-4o-mini
python python/samples/concepts/mcp/agent_with_twzrd_trust_verification.py

No TWZRD API key needed — trust scoring is free.

TWZRD Agent Intel

• MCP endpoint: https://intel.twzrd.xyz/mcp (Streamable HTTP)
• PyPI: pip install twzrd-agent-intel
• MCP config: {"mcpServers": {"twzrd-agent-intel": {"url": "https://intel.twzrd.xyz/mcp"}}}

   “Submit” is the act of uploading, submitting, transmitting, or distributing code or other content to any
   Project, including but not limited to communication on electronic mailing lists, source code control
   systems, and issue tracking systems that are managed by, or on behalf of, the Project for the purpose of
   discussing and improving that Project, but excluding communication that is conspicuously marked or
   otherwise designated in writing by You as “Not a Submission.”
   “Submission” means the Code and any other copyrightable material Submitted by You, including any
   associated comments and documentation.
2. Your Submission. You must agree to the terms of this Agreement before making a Submission to any

3. Originality of Work. You represent that each of Your Submissions is entirely Your original work.
   Should You wish to Submit materials that are not Your original work, You may Submit them separately

4. Your Employer. References to “employer” in this Agreement include Your employer or anyone else
   for whom You are acting in making Your Submission, e.g. as a contractor, vendor, or agent. If Your
   Submission is made in the course of Your work for an employer or Your employer has intellectual
   property rights in Your Submission by contract or applicable law, You must secure permission from Your
   employer to make the Submission before signing this Agreement. In that case, the term “You” in this
   Agreement will refer to You and the employer collectively. If You change employers in the future and
   desire to Submit additional Submissions for the new employer, then You agree to sign a new Agreement
   and secure permission from the new employer before Submitting those Submissions.
5. Licenses.

• Copyright License. You grant Microsoft, and those who receive the Submission directly or
  indirectly from Microsoft, a perpetual, worldwide, non-exclusive, royalty-free, irrevocable license in the
  Submission to reproduce, prepare derivative works of, publicly display, publicly perform, and distribute
  the Submission and such derivative works, and to sublicense any or all of the foregoing rights to third
  parties.

  import or otherwise dispose of the Submission alone or with the Project.

  No additional licenses or rights whatsoever (including, without limitation, any implied licenses) are
  granted by implication, exhaustion, estoppel or otherwise.

6. Representations and Warranties. You represent that You are legally entitled to grant the above
   licenses. You represent that each of Your Submissions is entirely Your original work (except as You may
   have disclosed under Section 3). You represent that You have secured permission from Your employer to
   make the Submission in cases where Your Submission is made in the course of Your work for Your
   employer or Your employer has intellectual property rights in Your Submission by contract or applicable
   law. If You are signing this Agreement on behalf of Your employer, You represent and warrant that You
   have the necessary authority to bind the listed employer to the obligations contained in this Agreement.
