privy-mcp

privy-mcp is a skill for Codex from tranfu-labs/tranfu-skills. It costs 126 tokens per session (1,886 once invoked), scanned A, original, MIT.

A documentation and implementation skill for Privy, a service that provides authentication and embedded cryptocurrency wallets. It uses Privy's official documentation together with the target project's existing code and installed SDK.

In plain words
What is it for?
Use it when adding or reviewing Privy login, wallet ownership, transaction controls, funding, webhooks, policies, or SDK migrations.
Why use it?
It keeps vendor information, project constraints, implementation choices, and verification results separate so integrations are based on current evidence.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

privy-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/privy_mcp.py, scripts/test_privy_mcp.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Privy MCP

Use current official Privy documentation as evidence, reconcile it with the target project's installed SDK and architecture, then implement and verify the requested integration. Prefer an MCP server already exposed by the runtime. If the project configures Privy only for another editor, use the bundled read-only client without changing Codex configuration.

Required outcome

Produce a named PRIVY_EVIDENCE_PACKET containing:

  • the question and detected project context;
  • official Privy claims with exact documentation URLs;
  • project constraints and conflicts kept separate from vendor claims;
  • the implementation or recommendation derived from both;
  • deterministic checks run, results, and unverified items.

For implementation requests, MUST edit only files authorized by the user and the project rules. For research-only requests, NEVER edit project files.

Workflow

CREATE A TODO LIST FOR THE TASKS BELOW:

  1. Read project agent rules, package manifests, relevant source/tests, architecture decisions, and MCP config candidates such as .cursor/mcp.json, .mcp.json, .vscode/mcp.json, and Codex MCP registrations. If the request is ambiguous about the desired behavior, ask one focused question and stop.
  2. Record the target runtime, installed Privy package names and versions, authentication boundary, wallet ownership model, chains, and requested outcome. Never infer an API shape solely from prior knowledge.
  3. Select the documentation path:
    • If a Privy MCP tool is already exposed, use it.
    • Otherwise run python3 <skill-dir>/scripts/privy_mcp.py server-info, then use the same client for the remaining calls.
    • If the endpoint is unavailable, use https://docs.privy.io/llms.txt, https://docs.privy.io/llms-full.txt, and the linked official pages as read-only fallbacks. Mark the MCP path unverified.
  4. Read the MCP resource mintlify://skills/privy once per task when available. Treat it as navigation guidance, not sufficient evidence for version-sensitive code.
  5. Search broadly with search_privy_docs, then read the most relevant .mdx pages with query_docs_filesystem_privy_docs. For REST details, inspect the official OpenAPI material exposed in the documentation filesystem. Read migration pages when installed SDK major versions or examples conflict.
  6. Build an evidence table before editing. Label each row official_doc, project_constraint, or inference; include a precise URL for every official_doc row. If official pages conflict, prefer the page matching the installed SDK/platform and report the conflict.
  7. For an implementation request, make the smallest change consistent with both the evidence table and project architecture. Never let a vendor recipe silently override an accepted ADR, ownership boundary, or server trust boundary.
  8. Run deterministic verification in repository-defined order: targeted tests, type check, lint, build, then any manual or live check explicitly authorized by the user. A documentation result is not runtime verification.
  9. Emit PRIVY_EVIDENCE_PACKET and end. State changed files, every verification command and result, exact citations, and all unverified behavior.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
