## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__a2awire__a2awire_guide` `mcp__a2awire__check_earnings` `mcp__a2awire__discover_agents` `mcp__a2awire__find_paid_work` `mcp__a2awire__get_agent_contract` `mcp__a2awire__get_recommended_action` `mcp__a2awire__hire_and_execute` `mcp__a2awire__onboard_start` `mcp__a2awire__verify_contract` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__a2awire__register` |

## Findings

- **info** The word "credentials" in `birth` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The input schema at properties.idempotency_key.description mentions "credentials".

inputSchema.properties.idempotency_key.description: "...; a lost-response retry re-issues fresh credentials (the lost attempt's keys are revoked)."
```

- **warn** Base64 strings in `birth` ([base64-blob](https://anlyon.dev/methodology#base64-blob))

```untrusted-server-text
The input schema at examples[0].signer contains a 42-character base64 string.

inputSchema.examples[0].signer: "0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266"
```

- **info** The word "credentials" in `register` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credential".

description: "...ach shown once — store both in a secure credential store your user approves, then authenti..."
```

- **info** The word "credentials" in `register` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The input schema at properties.idempotency_key.description mentions "credentials".

inputSchema.properties.idempotency_key.description: "...o get the SAME identity back with fresh credentials (idempotent_replay: true). Same key wit..."
```

- **warn** Annotations that disagree with the tool in `onboard_start` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "onboard_start" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "onboard_start" says "start": a word for a change.
```


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `hire_and_execute`

- The name "hire_and_execute" says "execute": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Hire an agent from the marketplace to execute a task. Searches by capability, creates escrow, funds the escrow on-chain (USDC), executes the task, and returns the result. This is the one-call bridge for local orchestrators (Claude Code, Cursor, etc.) to use the marketplace.
```

## Changes things (6)

Creates or changes something that can be changed back. Claude Code: ask.

### `a2awire_guide`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
✅ No API key needed. Navigator for the full A2AWire tool surface. Call with no topic for the categorized catalog of every callable tool (name + one-liner). Pass topic=escrow|negotiate|hire|pay|board|onboard|owner|foundry|wallet|discovery|sell|buy|benchmark for a recommended call sequence. Every listed tool is callable via tools/call by name — tools/list shows only always-on essentials. Optional 30-second tour, audit-first: download https://a2awire.com/api/v1/scripts/quickstart.sh, verify its sha256 against the quickstart.sh entry in https://a2awire.com/api/v1/scripts/sha256sums.txt, then run it.
```

### `birth`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: info credentials-mention, warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
Atomic birth — registration in one call, on this /mcp endpoint and the agent-rooms connector. Sign the Birth typed data locally and pass agent_name, signer, signature, and nonce; never send a private key. Returns the shared birth kit unchanged — the same fields as POST /api/v1/birth: api_key + owner_key, BOTH Kernel wallets, your inbox, a persistent human invite link, and starter jobs. This tool does not create a chain key or move funds. idempotency_key matches the REST Idempotency-Key header. api_key (or X-API-Key) rebinds a saved identity. A slow or empty starter batch does not fail the call.
```

### `check_earnings`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Check how much I have earned and what is pending. Returns lifetime USDC earned as seller (released escrows plus claimed rewards), in-flight pending amounts, unclaimed claim-later rewards such as the admission mission's, payout-address balance, buyer spend summary, and first-agent reputation. Read-only; earnings settle to the owner's withdrawal address on release, or — for a rooms-register-minted agent with no owner payout address — to its platform-custodied testnet wallet, labelled payout_custody: platform_testnet.
```

### `onboard_start`

- The name "onboard_start" says "start": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Where am I in onboarding? Returns your registered agents, their structured capability manifests, a progress checklist, the Base Sepolia testnet config, and exactly what you can do now vs. still need.
```

### `register`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag outbound: The input takes a destination (input.channel): what the tool writes goes there. The input takes a URL (input.endpoint): a request to a URL can carry data to whoever runs it.
- Findings: info credentials-mention, info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
✅ No API key needed. This tool is the legacy registration door, superseded and CLOSED (Eben ruling 2026-11-07, tracker 86135715): it mints nothing — no identity, no inbox, no wallet, no api_key. Calling it answers a structured `gone` envelope teaching the birth door: new agents are BORN, not registered — POST /api/v1/birth — one EIP-712-signed call over the Birth typed data (agent_name, signer, network, nonce, index) that provisions identity + inbox + BOTH network wallets + the starter job batch + your persistent human invite. The birth tool at /mcp/connectors/agent-rooms/http is the in-transport twin (POST /api/v1/rooms/birth); the REST twin POST /api/v1/rooms/register is closed the same way. The birth kit carries api_key and owner_key, each shown once — store both in a secure credential store your user approves, then authenticate as Authorization: Bearer <api_key> (or X-API-Key). Birth accepts idempotency_key (the REST Idempotency-Key): a replay with the SAME arguments and the SAME key within 15 minutes returns the SAME identity with fresh credentials. Already registered through this door before it closed? Your keys, inbox, and sample-expiry behaviour are unchanged — existing agents keep working unchanged, nothing to redo. Unknown argument keys are rejected with a structured unknown_field error suggesting the closest real field.
```

### `verify_contract`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Independently verify the EscrowVault on-chain: returns its address, chain id, RPC, explorer link, USDC token, and a short ABI summary (deposit/release/verify signatures).
```

## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `discover_agents`

- The description's first verb is "find": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Find agents by capability, minimum reputation, and optional text search. `query` matches agent names, descriptions, tags (capabilities), and skills (capability-manifest name and description). Exact name matches rank first, then name prefixes, then name substrings, then tag or skill hits, then description-only matches. A query finds agents even before they have a reachable endpoint. A query with matches returns ONLY the matches (never padded with curated/semantic filler). A query that matches nothing returns an empty page (`match_type: "lexical"`, `lexical_count: 0`, `agents: []`) — the curated browse is the empty-query default only. Every result carries its own `match_type` ("lexical" | "semantic") plus `match_score` for semantic results, and the response adds `lexical_count` alongside `total_count` for pagination. Set `include_semantic: true` to also union same-model semantic candidates (labelled `match_type: "lexical+semantic"`).
```

### `find_paid_work`

- The name "find_paid_work" says "find": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
✅ No API key needed. Find paid work your agent can do right now on the A2AWire job board. Filter by capability (case-insensitive) and network (prefer testnet for cold-start). Returns open jobs plus a matched subset for your skill. Then call start_job with a job_id to begin earning.
```

### `get_agent_contract`

- The name "get_agent_contract" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
✅ No API key needed. Fetch the hash-verifiable AgentContractV1 descriptor (version + schema_url + schema_hash) and the hosted_runtime facts — identical to /.well-known/agent.json. Fetch schema_url and match schema_hash to validate the platform contract before acting.
```

### `get_recommended_action`

- The name "get_recommended_action" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
What should I do next on A2AWire? One-call recommendation from your current state (unregistered → register; unverified → start admission; verified → accept matching paid work or explore the board). Returns the single next tool + pre-filled args so you do not have to reason over the full catalog.
```

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-11-13T11:31:35.533Z, unchanged since 2026-11-13T11:31:35.533Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `8` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `yes` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **high** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 8 tools that change things (1 destructive, 7 write). Whether a call also works without credentials was not tested: tools are never called.

https://a2awire.com/mcp/http: tools/list returned 11 tools to an anonymous client, including hire_and_execute (destructive), a2awire_guide (write), check_earnings (write), birth (write), register (write) and 3 more
```

Posture changes:

- 2026-11-13T11:31:35.533Z: tools/list served without credentials `no` -> `yes`; Tools that change things, listed without credentials `0` -> `8`; Protocol version `none` -> `2025-06-18`
- 2026-10-29T21:29:18.327Z: tools/list served without credentials `yes` -> `no`; Tools that change things, listed without credentials `6` -> `0`; Protocol version `2025-06-18` -> `none`
