But there's a gap: **no pre-execution tool parameter verification**.\n\n## What Prompt Security Does vs. What's Missing\n\n**Does**: Content scanning of tool responses \u2014 PII detection, prompt injection in outputs, DLP  \n**Doesn't**: Schema validation of arguments before execution, SSRF detection in URLs before requests, command injection detection before shell execution, integrity checking for schema drift\n\nThe security boundary is after the tool executes. By then, SSRF has reached the metadata service, command injection has executed, path traversal has accessed files.\n\n## The Complete Stack\n\n```\nAgent \u2192 [CCS: Pre-execution, ~7.5\u03bcs] \u2192 [Prompt Security: Content inspection] \u2192 MCP Server\n         Blocks malformed calls          Detects data leakage in responses\n```\n\nCCS (7-dim runtime verification) + Prompt Security (content inspection) = complete coverage.\n\n## Performance\n\n| Layer | Latency | What it catches |\n|-------|---------|----------------|\n| CCS pre-execution | ~7.5\u03bcs (in-process) | Schema violations, SSRF, injection, drift |\n| Prompt Security post-execution | ~10-50ms | PII leakage, data exfiltration, content injection |\n\n## The Market Context\n\n- Wiz: MCP in 80% of cloud environments, 1/6 exposed to internet\n- RufRoot CVE-2026-59726 (CVSS 10.0): Full RCE in 67K-star MCP platform\n- LiteLLM CVE-2026-30623 (CVSS 9.8): MCP command injection\n- Every enterprise deploying agents needs pre-execution + post-execution security\n\n## Links\n- [CCS Framework](https://github.com/Correctover/Correctover) | [IETF Draft](https://datatracker.ietf.org/doc/draft-cs2-mcp-ccs/) | [PANW Same Gap](https://gist.github.com/Correctover/19a40ba66828f148eb45c10d389bf227)\n", "creation_timestamp": "2026-08-04T08:30:53.140630Z"}
