Category Security
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 Security46
- 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 3 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 check failed: the endpoint is reachable over plaintext HTTP. See how to fix → View diagnostics → Fail
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability76
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 477 tokens (~159/item across 3 items; 3 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 Management100
- No destabilizing schema changes in the last 30 days.Pass
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 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities20
- Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28. See how to fix → Fail

Checks we could not complete (1)
These are gaps on our side, not findings about this hosted endpoint. We only credit what we can confirm, so a category made up entirely of them scores 0.
- Authorization in Endpoint SecurityAuthorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.

- Supply Chain SecurityScored on package channels only. This is a hosted endpoint, so there is nothing to install or inspect.

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 →
issue_receipt ~293
Mint a verifiable provenance receipt for an autonomous-agent action. Returns a signed (ed25519), content-hashed (SHA-256), server-timestamped receipt that is hash-chained to this agent's prior receipts (tamper-evident audit trail). Pass the raw inputs/outputs (we hash them — raw data is never stored) OR pre-computed sha256 hashes. Use for compliance, audit trails, and dispute resolution of agentic actions. PAID: $0.01 USDC/call via x402.
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | yes | What the agent did, e.g. 'sent_payment' or 'approved_refund' or 'tool_call:search'. |
| agent_id | string | – | Stable identifier for the acting agent (chains group by this). |
| inputs | – | – | Raw inputs to the action (any JSON). Hashed to a commitment; raw data not stored. |
| inputs_hash | string | – | Alternatively, a pre-computed sha256 hex (or 'sha256:<hex>') of inputs. |
| metadata | object | – | Optional small key/value context (model, version, request id, etc.). |
| outputs | – | – | Raw outputs/result of the action (any JSON). Hashed to a commitment; raw data not stored. |
| outputs_hash | string | – | Alternatively, a pre-computed sha256 hex (or 'sha256:<hex>') of outputs. |
No output schema declared.
No examples provided.
list_receipts ~79
List the receipt hash-chain for an agent_id, newest first (id, action, timestamp, sequence, hashes, verifyUrl). Use to audit everything a given agent has attested. FREE.
| Name | Type | Req | Description |
|---|---|---|---|
| agent_id | string | yes | The agent whose receipts to list. |
| limit | number | – | Max receipts (default 25, max 100). |
No output schema declared.
No examples provided.
verify_receipt ~105
Verify a receipt by id (or by passing the full receipt object). Recomputes the content hash, confirms the id commits to the body, and checks the ed25519 signature. Returns the verification checks plus the provenance record (action, agent, input/output hashes, timestamp, chain position). FREE.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | – | Receipt id, e.g. 'rcpt_...'. |
| receipt | object | – | Alternatively, the full receipt object to verify offline-style. |
No output schema declared.
No examples provided.
How do I install the Agent Receipts MCP server?
Agent Receipts is a hosted endpoint at https://agent-receipts.dropwatchhq.com/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.

What is the Agent Receipts MCP server?
Agent Receipts is an MCP server listed in the public MCP registry as com.dropwatchhq/agent-receipts. Issue & verify signed (ed25519), hash-chained, timestamped provenance receipts for agent actions. This page covers its hosted endpoint (https://agent-receipts.dropwatchhq.com/mcp).
Is the Agent Receipts MCP server safe to use?
Agent Receipts scores 71 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 Receipts MCP server expose?
Agent Receipts exposes 3 tools: issue_receipt, verify_receipt, list_receipts. Their descriptions and schemas cost roughly 477 tokens of context every time the server is loaded.
Does the Agent Receipts MCP server require authentication?
No. We connected to Agent Receipts without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Agent Receipts MCP server still maintained?
Agent Receipts is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What did VerifyMCP test on the Agent Receipts MCP server?
VerifyMCP ran 12 checks on Agent Receipts, covering TLS certificate, HTTPS, HSTS header, DNSSEC and 8 more. One item could not be completed, a gap on our side rather than a finding about Agent Receipts: Authorization. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
