Mental Capacity Act paperwork that would survive a Court of Protection challenge.
Mental Capacity Act assessments and Best Interest decision records follow a fixed legal structure: functional test, diagnostic test, best interest checklist. Get it right and you've protected the person and your organisation. Get it wrong and you're potentially in front of the Court of Protection. Your MCA agent drafts these records from your assessment notes, following the legal framework precisely — so your qualified staff can focus on the assessment itself, not the paperwork.
What Your Agent Actually Does
Your MCA agent drafts capacity assessments and best interest decision records from your clinical notes — following the legal framework precisely, every time.
Follows the legal framework exactly
Functional test — can they understand, retain, weigh, and communicate? Diagnostic test — is there an impairment of mind or brain? Best interest checklist — all statutory factors considered. Your agent structures every record to the framework, so nothing is missed.
Drafts from your assessment notes
Your assessor's notes, observations, and clinical input go in. A structured, legally sound draft comes out. The agent doesn't make capacity judgements — it documents yours in the way the law requires.
Ensures decision-specific assessments
Capacity is decision-specific — that's the law. Your agent ensures each assessment is tied to a specific decision at a specific time, not a generic "lacks capacity" catch-all that wouldn't survive scrutiny.
Produces audit-ready records
Every assessment, every best interest decision, fully documented with the reasoning chain visible. When the local authority, CQC, or a court asks to see your MCA records, you hand over a complete, consistent file.
The real numbers.
| Qualified staff time writing MCA records (1–3 hours each) | £4,000–£8,000/year |
| Training and re-training on MCA documentation | £500–£1,500/year |
| Legal risk from poorly documented assessments | Potentially severe |
| Realistic annual cost | £4,500–£9,500 |
| Agent build (one-off, configured to your templates) | £2,000–£3,500 |
| Monthly running costs (hosting + AI usage) | £80–£150/month |
| Template updates as case law evolves | Included in first year |
| Realistic first-year total | £2,960–£5,300 |
The Mental Capacity Act is one of the most important pieces of legislation in social care — and one of the most inconsistently applied. Not because staff don't understand it, but because documenting it properly takes time that nobody has. So assessments get done but not recorded. Or recorded but not in the right format. Or in the right format but without the reasoning chain a court would need to see.
Your agent doesn't assess capacity — your qualified staff do that. It makes sure the assessment is documented in a way that's legally sound, every time, without turning a 30-minute assessment into a two-hour paperwork exercise.
Good fit / not a fit.
This works brilliantly for:
- Care homes and supported living services conducting regular MCA assessments
- Providers where MCA documentation has been flagged as incomplete or inconsistent
- Services supporting people who lack capacity for multiple decisions
- Any provider where qualified staff spend more time writing MCA records than conducting assessments
This probably isn't for you if:
- You rarely conduct MCA assessments (e.g. your client group generally has full capacity)
- You have a dedicated MCA lead with capacity to document every assessment thoroughly
- Your local authority handles all MCA assessments for your service users
Handled like the sensitive data it is.
Care records are special category data under UK GDPR, and we treat them that way. Your agent runs on Claude via AWS Bedrock with an EU-only inference profile — meaning prompts and outputs never leave the EU, and are never used to train a model. Protected under Anthropic’s enterprise Business Associate Agreement.
Every run is logged for audit, every output is a draft your registered manager reviews and approves, and your data lives in a tenant isolated from every other customer. We’re working towards NHS Data Security and Protection Toolkit Standards Met and Cyber Essentials Plus, and we’ll hand you a pre-filled DPIA template you can drop into your own records.

Let's talk.
We'll look at your current MCA assessment process — how often you're conducting them, what template you use, and where the documentation bottleneck sits. Usually a 15-minute conversation.
