HIGHLong base64-encoded blob hidden in the skill documentationSS-SKILL-INJECT-B64-PAYLOAD-01 · Prompt injection · docs/prefab/actions/open-file-picker.md
A base64 string of 128+ characters appears in a documentation file. Encoded prompt injection hides the hostile instruction in base64 — invisible to keyword filters — and relies on the agent's ability to decode it at runtime. There is no normal authoring reason to embed a multi-hundred-byte base64 blob in skill docs.
- Decode the base64 string and confirm it is not an instruction directed at the agent.
- Move any legitimate binary or signature data into a dedicated file (
*.sig,SIGNATURES) outside the documentation.

Property Shared
<!-- mcp-name: io.github.paulieb89/property-shared -->
UK property data in one package. Pulls Land Registry sales, EPC certificates, Rightmove listings, rental yields, stamp duty calculations, planning portal links, and Companies House records.
Use it as a Python library, CLI, HTTP API, or MCP server.
What You Get
| Data Source | What It Returns |
|---|---|
| Land Registry PPD | Sold prices, dates, property types, area comps with median/percentiles |
| EPC (GOV.UK) | Energy ratings, floor area, heating costs. England & Wales only. Certificate lookup and summary search — see EPC notes below |
| Rightmove | Current listings (sale + rent), prices, agents, listing details |
| Yield Analysis | Gross yield from PPD sales + Rightmove rentals combined |
| Stamp Duty | SDLT calculation with April 2025 bands, BTL surcharge, FTB relief |
| Block Analyzer | Groups flat sales by building to spot investor exits |
| Planning | Local council planning portal lookup (99 verified councils, stdio only) |
| Companies House | Company search and lookup by name or number |

EPC notes (v1.14.0)
The EPC service moved to a GOV.UK Bearer API. Set EPC_API_TOKEN; the old EPC_API_EMAIL/EPC_API_KEY pair authenticated against a retired host and is not a supported fallback.
What the new upstream supports, and what it does not:
- Certificate lookup by certificate number — full detail, one request.
- Summary search by postcode — returns address, UPRN (often absent), energy
band, registration date and schema type. It does not return energy score, floor area or property type; those exist only on a full certificate.
- A postcode selects an area, never a property. Identifying one property
needs a UPRN or an address matching a certificate exactly (case, punctuation and a leading Flat/Apartment designator aside). Anything less — no address, no match, or several matches — is refused rather than resolved to a best guess. See USER_GUIDE.md for the CLI and REST surfaces.
- Area statistics are limited to the record count and, when the bounded
response contains every matching summary, the rating distribution. Property-type breakdown and floor-area statistics are reported as None — unavailable, not zero — because producing them would mean one request per certificate.
- Coverage is England and Wales. Scotland, Northern Ireland and the Channel
Islands return "no certificates found": a coverage boundary, not a statement about a property.
- Pagination is not a stable snapshot. Responses carry
complete,
duplicates_removed and unusable_rows; no operation claims a complete harvest of an area.
- Ambiguous address matches are refused rather than resolved to an arbitrary
neighbouring certificate.
search_all_by_postcode() is unsupported — use search_summaries() for candidate discovery, then get_certificate() for the one you need.
Environment Variables
Create a .env file in the repo root (it is gitignored) with the variables you need.
Leave optional variables out entirely rather than assigning them empty.KEY=sets an empty string, which is not the same as unset:os.getenv("KEY", "default")returns"", so the default never applies. This bit the EPC live tests, which sent an empty postcode upstream.
Key variables:
| Variable | Required For | Description |
|---|---|---|
EPC_API_TOKEN | EPC lookups | Bearer token from GOV.UK EPC data |
EPC_API_EMAIL | (deprecated) | Retired service; parsed only to raise a configuration error |
EPC_API_KEY | (deprecated) | Retired service; not a supported fallback |
COMPANIES_HOUSE_API_KEY | Company search | Free key from Companies House |
RIGHTMOVE_DELAY_SECONDS | No (default 0.6s) | Rate limit delay for Rightmove scraping |
OPENAI_API_KEY | Planning scraper | Vision-guided planning portal scraper |
Land Registry PPD and Rightmove work without credentials.
