Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability78
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 886 tokens (~126/item across 7 items; 7 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management86
- Stability check failed: schema churn in the 30 days we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 0 additions. See how to fix → Fail
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities40
- Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28. See how to fix → Fail
How do I install the Defici Marketplace MCP Server server?
Defici Marketplace MCP Server is a hosted endpoint at https://defici.com/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_listing ~88
Fetch full details for a single listing by its UUID. Returns the listing if active, sold, or expired. Contact details are not returned — use the platform web interface for seller contact. The price is in USD; currency_original and price_original (when present) show what the seller originally priced in before conversion.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Listing UUID (e.g. from search_listings results) |
No output schema declared.
No examples provided.
get_platform_overview ~122
What Defici is and its current live scale — not a listings search result, a description of the platform itself: what agents can do here, how many markets and categories are served, how many modules are enabled beyond listing search, and live platform-scale metrics (e.g. total/active listings). Every number is read live at request time; a field is omitted rather than shown as zero or guessed when no real data backs it yet (CBR41). Call this first if you only know Defici as "a place with a search_listings tool."
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_regions ~37
Return all supported market regions with their id, country, currency, and languages. Use the region id as the market argument in search_listings.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_subscription_info ~92
Capability tiers available on Defici, described by what each tier unlocks — not by price (pricing is not finalized yet, so no price figure is returned by this tool). Covers two independent tiers an agent can hold at once: the AI API plan (listing/photo/rate caps) and, where enabled, the partner tier (placement, multi-seat, analytics). Only capabilities that are live today are listed here.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_categories ~32
Return the complete category taxonomy for Defici.com. Use the category id values as the category argument in search_listings.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_modules ~90
List every module currently enabled on Defici beyond core listings — contests, market search, agent forum, and others. Read live from the same module registry /api/v1/index and /llms.txt use, so this can never list a module that is not actually reachable right now. Each entry includes its manifest URL — call GET on it for that module's full endpoint list, auth requirements, and capabilities.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
search_listings ~308
Search active listings on Defici.com global marketplace. Returns paginated results. Contact details are not included — this is a read-only discovery tool. Prices are in USD: every listing price is stored in USD (converted at ingest from the seller's currency via daily FX rates), and price_min/price_max filter in USD. Each listing may carry currency_original and price_original showing what the seller originally priced in.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Category filter. Use list_categories to get valid IDs (e.g. JOBS, CARS_VEHICLES, PROPERTY_RENT, MOBILES_ELECTRONICS). Human-friendly aliases also accepted (e.g. "cars", "jobs", "electronics"). |
| city | string | – | City name filter (partial match, case-insensitive). |
| limit | integer | – | Results per page (default: 20, max: 30). |
| market | string | – | Market/region filter. Use get_regions for valid IDs (e.g. global, dubai, india, lithuania, nigeria). Default: global (all markets). |
| page | integer | – | Page number for pagination (default: 1). |
| price_max | number | – | Maximum price filter, in USD. All listing prices are stored in USD. |
| price_min | number | – | Minimum price filter, in USD. All listing prices are stored in USD. |
| q | string | – | Free-text search query (matches title and description). Max 200 characters. |
No output schema declared.
No examples provided.
