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.

Model	Per session	Once invoked
Fable 5.1	$0.00634	$0.00634
Opus 5.5	$0.00254	$0.00254

Security

Grade A, and why

mcp-oidc-provider AGENTS.md 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 1mo ago.

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.

Project Instructions for mcp-oidc-provider

Overview

This is mcp-oidc-provider - an Express middleware that acts as an OIDC provider for MCP (Model Context Protocol) servers with support for any OIDC-compliant identity provider as its backend.

Key Concepts

OIDC Provider: Acts as a man-in-the-middle between MCP clients and upstream identity providers
Two Deployment Modes:
- Standalone: Separate OIDC server, MCP server proxies auth requests to it
- Integrated: Single Express app hosting both OIDC and MCP
Storage: Uses Keyv for abstraction - supports any Keyv-compatible backend (Tigris, Redis, in-memory)

Project Structure

src/oidc/ - Core OIDC server implementation (createOidcServer, OidcClient)
src/mcp/ - MCP-specific utilities (setupMcpExpress, createMcpAuthProvider)
src/core/ - Core provider implementation
src/utils/ - Utilities (JWKS generation, etc.)
example/ - Example implementations
