Tools as reported by the server

• lookup_control
  Get one NIST SP 800-171 Rev 2 security requirement by number (e.g. "3.5.3"): the full requirement text, its control family, and its exact DoD Assessment Methodology (SPRS) point weight, including the sliding-scale rules for 3.5.3 (MFA) and 3.13.11 (FIPS cryptography). Call this when the user asks wh
• list_controls
  List NIST SP 800-171 Rev 2 requirements with their DoD Assessment Methodology (SPRS) weights, optionally filtered by control family name or by point weight (5, 3, or 1). Call this to enumerate the 110 CMMC Level 2 controls, to find all 5-point (highest-impact) requirements, or to see everything in o
• calculate_sprs_score
  Compute an exact SPRS score per the DoD Assessment Methodology: start at 110 and subtract each unimplemented requirement's Annex A weight (floor −203). Pass the control numbers that are NOT implemented; optionally pass 3.5.3 and/or 3.13.11 as partially implemented for their sliding-scale values (MFA
• get_assessment_objectives
  Get the official NIST SP 800-171A assessment objectives for one NIST SP 800-171 Rev 2 requirement - the exact "Determine if..." objectives a CMMC Level 2 assessor scores, plus the potential assessment methods (what an assessor examines, who they interview, what they test). Call this when the user as
• crosswalk_control
  Map a security control across frameworks: NIST SP 800-171 Rev 2 ↔ NIST SP 800-53 (FedRAMP Moderate) ↔ NIST CSF 2.0 ↔ SOC 2 Trust Services Criteria. Accepts an 800-171 number ("3.5.3"), an 800-53 id ("AC-2"), a CSF category ("PR.AA" style / "GV.RM"), or a SOC 2 criterion ("CC6"). Call this when the u
• determine_cmmc_level
  Determine which CMMC level (1, 2, or 3) applies to a defense contractor based on the data they handle and the clauses in their contracts, and - separately - which assessment type may actually be designated today. Those are not the same question: CMMC Phase II was suspended on 13 July 2026, so C3PAO
• list_level1_practices
  List all 17 CMMC Level 1 basic safeguarding practices with their FAR 52.204-21 clause citations - the complete requirement set for contractors handling Federal Contract Information (FCI) only. Call this when the user asks what CMMC Level 1 requires.
• generate_poam_entries
  Turn a list of unimplemented NIST SP 800-171 controls into structured Plan of Action & Milestones (POA&M) entries, and - the part that decides whether the plan is usable - sort them by eligibility under 32 CFR 170.21. Most gaps CANNOT go on a CMMC Level 2 POA&M: the rule bars every requirement worth
• check_contract_type_eligibility
  Determine whether a contractor can legally be awarded a given contract type, based on the business systems that type requires. A cost-reimbursement contract may be awarded only if the accounting system is adequate for determining costs (FAR 16.301-3), and T&M billing cannot be substantiated without
• lookup_clause
  Explain what a FAR or DFARS cybersecurity clause obliges a contractor to do: what triggers it, the concrete duties, the reporting deadlines, what it flows down to subcontractors, and which other clauses come with it. Covers 52.204-21, 252.204-7008, 252.204-7012, 252.204-7019, 252.204-7020, 252.204-7
• scope_assessment
  Work out which assets fall inside a CMMC assessment boundary, and what each category obliges. Returns the DoD asset categories (CUI Asset, Security Protection Asset, Contractor Risk Managed Asset, Specialized Asset, Out-of-Scope) with how each is treated at assessment, plus the CUI categories that m
• lookup_rev3_requirement
  Get one NIST SP 800-171 REVISION 3 requirement by its zero-padded number (e.g. "03.01.01"): the requirement statement, its organization-defined parameters, the 800-171A Rev 3 assessment objectives, and whether it was withdrawn. Rev 3 has 97 active requirements of 130 numbered across 17 families, wit
• crosswalk_revisions
  Explain how NIST SP 800-171 Rev 2 and Rev 3 differ, and what happened to a specific requirement between them. Call this when someone is implementing Rev 3 early, holds a Rev 3 citation and needs the Rev 2 obligation, or asks which revision applies to them. Answers the question DoD guidance forces on
