## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-04.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 9 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 67/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 605 tokens (~67/item across 9 items; 9 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 97/100
  - Stability observed for 29 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 12% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (9)

### `search_resources` (~139 tokens)

Search the marketplace by keyword and/or filters (network, asset, scheme, payTo, maxUsdPrice). Text queries rank by relevance; filter-only queries rank by 30-day call volume.

Input parameters:

- `asset` (string)
- `limit` (integer)
- `maxUsdPrice` (number)
- `network` (string): e.g. eip155:8453, solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp
- `payTo` (string)
- `query` (string): Free-text keyword search
- `scheme` (string)

### `get_resource` (~47 tokens)

Fetch one resource's full record by slug or numeric id: description, accepts[], output schema, quality signal, and agent-first metadata where the provider supplied it.

Input parameters:

- `slug` (string, required)

### `get_pricing` (~48 tokens)

Get just the price/accepts[] for a resource, without the full record — cheaper for an agent that only needs to decide whether it can afford something.

Input parameters:

- `slug` (string, required)

### `discover_provider` (~25 tokens)

List every resource published by a given provider host.

Input parameters:

- `host` (string, required)

### `list_resources` (~53 tokens)

Paginated listing of every indexed resource, ranked by 30-day call volume (or recency with sort="recent").

Input parameters:

- `limit` (integer)
- `offset` (integer)
- `sort` (string)

### `list_saylor_official` (~154 tokens)

List verified Saylor Innovations x402 endpoints directly from the live Saylor manifest. Does not depend on the D1 catalog, so it keeps working during catalog quota exhaustion. Supports query, family, tag, network, asset, payTo, maxUsdPrice, limit and offset filters.

Input parameters:

- `asset` (string)
- `family` (string): Endpoint family such as evm, solana, research, package, market, kb, or guide.
- `limit` (integer)
- `maxUsdPrice` (number)
- `network` (string)
- `offset` (integer)
- `payTo` (string)
- `query` (string)
- `tag` (string)

### `get_stats` (~30 tokens)

Catalog-wide totals: listings, resources, accepts, merchants, 30-day call volume, network/source breakdown.

### `discover_agents` (~52 tokens)

Search or list the A2A agent registry — other agents’ cards (name, skills, provider, protocol version), not Agent Bazaar’s own.

Input parameters:

- `limit` (integer)
- `query` (string)

### `get_agent` (~28 tokens)

Fetch one registered agent's full card by slug or numeric id.

Input parameters:

- `slug` (string, required)

### Is the Agent Bazaar MCP server safe to use?

Agent Bazaar scores 74 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Agent Bazaar MCP server expose?

Agent Bazaar exposes 9 tools: search_resources, get_resource, get_pricing, discover_provider, list_resources, and 4 more. Their descriptions and schemas cost roughly 576 tokens of context every time the server is loaded.

### Does the Agent Bazaar MCP server require authentication?
