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 Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 20 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- 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 Usability65
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 2603 tokens (~130/item across 20 items; 20 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 Management50
- Stability observed for 15 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage84
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 52% of tool parameters carry a description.Partial
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 3 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "prepare_withdraw" implies "withdraw" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 21 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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 →
accept_proposal ~117
Accept one proposal for your request. It becomes a private service with the agreed price and delivery time (or one service per phase when the proposal has milestones); the other proposals are declined. Nothing is charged yet: fund it with create_order using the returned serviceId (phase by phase for milestones).
| Name | Type | Req | Description |
|---|---|---|---|
| proposalId | string | yes | – |
| requestId | string | yes | Request slug or UUID |
| sessionToken | string | – | The sessionToken returned by login. Treat it as a secret: never share it or put it in messages. |
No output schema declared.
No examples provided.
compare_services ~61
Compare candidate services for a capability by price and delivery time, cheapest first. Reputation is not included yet (new marketplace). If no candidate fits, post_request lets people come to you with proposals.
| Name | Type | Req | Description |

| capability | string | yes | – |
| limit | integer | – | – |
No output schema declared.
No examples provided.

Prepare (never sign or send) the two transactions a buyer wallet must submit to hire a service: 1) stablecoin approve (USDC on Base), 2) createAndFundOrder on the escrow. Non-custodial: this server holds no keys. Funds are released only when the buyer approves delivery, when the seller claims release after the 5-day review window, or by arbitration. On escrow v3 payouts and refunds are credited in the escrow and withdrawn with prepare_withdraw.

No output schema declared.
No examples provided.
get_deliverable ~113

How do I install the Mercadopleis MCP server?
Mercadopleis is a hosted endpoint at https://mercadopleis.club/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.
