## Quality 63/100 (needs work)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: register_key_release (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); read_memory (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); share_memory_key (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 831 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 25 (weight 15)

- warn `stability.changes`: 6 tool changes in 30 days
- fail `stability.rug_pull`: 2 tools kept their name but changed most of their description in 30 days; review before trusting them

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 6, about 831 tokens to load them all
- tool set hash: 5613dd55cfbfb5649537b4b984d0b132
- tools last changed: 2026-10-02T21:03:35.547Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.agtrepo/agtrepo-memory.svg)](https://protogrid.dev/servers/io.github.agtrepo/agtrepo-memory)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-02 `send_feedback` changed (description) **meaning changed**
  - before: Free. Sends feedback about the Protocol to its operators. Name is optional (omit for anonymous feedback); message is limited to 1000 characters.
  - after: Free. Sends a message to the human operators of this service: a bug report, a problem with these tools or the documentation, or a suggestion. It is read by people, not processed by software, and nothing is returned beyond an acknowledgement. Do NOT use it for status updates, progress notes, task narration, error logs, or as a fallback when another tool is unavailable or a payment cannot be made -- it cannot complete, retry or work around any task. Name is optional (omit for anonymous feedback); message is limited to 1000 characters.
- 2026-10-02 `send_feedback` changed (description)
  - before: Free. Sends feedback about the Protocol to its operators by email. Name is optional (omit for anonymous feedback); message is limited to 1000 characters.
  - after: Free. Sends feedback about the Protocol to its operators. Name is optional (omit for anonymous feedback); message is limited to 1000 characters.
- 2026-10-02 `register_key_release` changed (description, inputSchema) **meaning changed**
  - before: Free. Creator registers a wrapped content key for a specific reader's public key, proven by an EIP-191 signature over `agtrepo-memory:key-release:{id}:{readerPubKey}:{timestamp}`.
  - after: Free. Creator registers a wrapped content key for a specific reader's public key, proven by an EIP-191 signature over `agtrepo-memory:key-release:{id}:{readerPubKey}:{timestamp}:{sha256hex(wrappedKey)}` (the hash is lowercase hex SHA-256 of the wrappedKey string exactly as sent, so the signature can't be reused with a different key). `{id}` only exists after store_persistent_memory returns, and `{timestamp}` is Unix epoch milliseconds (an integer, not an ISO date) that must be within 5 minutes of the server clock -- so sign at call time; a pre-signed or archived signature will be rejected.
- 2026-10-02 `share_memory_key` changed (inputSchema)
- 2026-10-02 `extend_memory` changed (description)
  - before: Extends a memory's TTL by 30 days, up to a maximum total lifetime of 365 days from creation. Requires x402 payment.
  - after: Extends a memory's TTL by 30 days, up to a maximum total lifetime of 365 days from creation. Requires x402 payment. An expired memory is deleted and cannot be extended.
- 2026-10-02 `store_persistent_memory` changed (description, inputSchema)
  - before: Stores encrypted text memory (base64 ciphertext, up to 16384 bytes). Automatically completes x402 payment challenges.
  - after: Stores encrypted text memory (standard padded base64 ciphertext, up to 16384 bytes decoded). Requires x402 payment. Returns the memory's id.

## Packages

_none_

## Tools (6)

- `extend_memory`: Extends a memory's TTL by 30 days, up to a maximum total lifetime of 365 days from creation. Requires x402 payment. An expired memory is deleted and cannot be extended.
- `read_memory`: Reads an encrypted memory by id. Requires x402 payment. 70% of the fee accrues to the memory's creator.
- `register_key_release`: Free. Creator registers a wrapped content key for a specific reader's public key, proven by an EIP-191 signature over `agtrepo-memory:key-release:{id}:{readerPubKey}:{timestamp}:{sha256hex(wrappedKey)}` (the hash is lowercase hex SHA-256 of the wrappedKey string exactly as sent, so the signature can't be reused with a different key). `{id}` only exists after store_persistent_memory returns, and `{timestamp}` is Unix epoch milliseconds (an integer, not an ISO date) that must be within 5 minutes of the server clock -- so sign at call time; a pre-signed or archived signature will be rejected.
- `send_feedback`: Free. Sends a message to the human operators of this service: a bug report, a problem with these tools or the documentation, or a suggestion. It is read by people, not processed by software, and nothing is returned beyond an acknowledgement. Do NOT use it for status updates, progress notes, task narration, error logs, or as a fallback when another tool is unavailable or a payment cannot be made -- it cannot complete, retry or work around any task. Name is optional (omit for anonymous feedback); message is limited to 1000 characters.
- `share_memory_key`: Free. Releases a previously creator-registered wrapped key to a reader, or the raw content key for a public document.
- `store_persistent_memory`: Stores encrypted text memory (standard padded base64 ciphertext, up to 16384 bytes decoded). Requires x402 payment. Returns the memory's id.
