SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Data Exfiltration · line 46 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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 | $0.00025 | $0.01017 |
| Opus 5 | $0.00013 | $0.00508 |
| Sonnet 5 | $0.00005 | $0.00203 |
| Haiku 4.5 | $0.00003 | $0.00102 |
Grade A, and why
mcp-gateway-configuration 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.
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.

MCP Gateway Configuration Skill
Context
This skill applies when:
- Configuring multi-server MCP gateway deployments with the EP MCP Server
- Routing MCP tool requests across multiple parliamentary data sources
- Setting up access control policies for different MCP client types
- Integrating the EP MCP Server alongside other MCP servers in a unified gateway
- Configuring tool namespacing to avoid conflicts between MCP servers
- Managing connection pooling and failover for EP API backend connections
- Deploying MCP gateway configurations for development, staging, and production environments
MCP gateways enable AI applications to access multiple MCP servers through a single connection point. The EP MCP Server must be configurable as a backend within larger MCP gateway architectures.
Rules
- Namespace All Tools: Prefix EP tools with
ep_oreuroparl_to avoid naming collisions with other MCP servers in a gateway - Define Explicit Tool Routes: Map each MCP tool to its backend server explicitly; avoid wildcard routing that could expose unintended tools
- Configure Per-Client Access Control: Assign tool access policies based on client identity; not all clients should access all EP data tools
- Use Environment-Based Configuration: Store gateway configuration in environment variables or secure config files, never hardcoded
- Implement Health Checks: Configure readiness and liveness probes for the EP MCP Server backend within the gateway
- Set Timeout Policies: Define per-tool timeout values; EP API calls may have variable latency depending on dataset size
- Enable Request Correlation: Propagate correlation IDs from gateway to EP MCP Server for end-to-end request tracing
- Configure Rate Limiting at Gateway Level: Enforce rate limits at the gateway to protect the EP API from excessive downstream requests
- Support Graceful Degradation: If the EP backend is unavailable, return informative error responses rather than gateway-level failures
- Version Tool Registrations: Include version metadata in tool listings so clients can detect breaking changes
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.

mcp-gateway-configuration is a skill published in the GitHub repository Hack23/European-Parliament-MCP-Server (28 stars, last pushed yesterday), licensed Apache-2.0. It adds 25 tokens to every session and 1,017 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
