Matches of fixed checks, with the text they matched.

query_memoryExecute a structured query plan over your encrypted knowledge graph.1 finding
Why it is in this group
- The name "query_memory" says "query": a word for reading.
- The description's first verb is "execute": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Findings
- Warn
  The server marks "query_memory" read-only (readOnlyHint: true), and its own name, description or input give the class "write".
  Matched text
  annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "query_memory" says "query": a word for reading.
  What this check looks for
Description, as the server wrote it
Execute a structured query plan over your encrypted knowledge graph. Returns STRUCTURE ONLY (node_type, name_hash, relationships, chunk_ids, timestamps) — never content. Plan schema: { "entity_filters": [{"node_type": <type>} | {"name_hash": <sha256-hex>}], "edge_filters": [{"relationship": <rel>, "direction": "out"|"in"|"both"}], "temporal_bounds":{"valid_from_after": <ISO8601>, "valid_to_before": <ISO8601>}, "limit": <int <= 200>, "include_neighbours_depth": <0-5> } node_type in {entity, concept, decision, person, organisation, event, source, synthesis}. relationship in {references, contradicts, supports, supersedes, caused_by, related_to, part_of, informed_by, led_to, verifies}. Account scope is enforced server-side; it cannot be set from the plan.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
query_memory_contentExecute a structured query plan and return DECRYPTED memory CONTENT (node names, summaries, properties; edge evidence + endpoint names) alongside structure.1 finding
Why it is in this group
- The name "query_memory_content" says "query": a word for reading.
- The description's first verb is "execute": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Findings
- Warn
  The server marks "query_memory_content" read-only (readOnlyHint: true), and its own name, description or input give the class "write".
  Matched text
  annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "query_memory_content" says "query": a word for reading.
  What this check looks for
Description, as the server wrote it
Execute a structured query plan and return DECRYPTED memory CONTENT (node names, summaries, properties; edge evidence + endpoint names) alongside structure. SAME plan schema as query_memory. REQUIRES a memory:read:content-scoped token — a structure-only token is rejected (403) by ENYAL. Account scope is enforced server-side; it cannot be set from the plan.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
renderRender a structured query as a STRUCTURE-ONLY result set (β = structure; identical shape to query_memory).No findings
Why it is in this group
- 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.
Description, as the server wrote it
Render a structured query as a STRUCTURE-ONLY result set (β = structure; identical shape to query_memory). Reserved for richer rendering when content access (γ) lands.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
verify_chunkLook up one identifier in ENYAL's PUBLIC verification index (relays GET /api/v1/verify/lookup/{id}; no decryption).No findings
Why it is in this group
- 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.
Description, as the server wrote it
Look up one identifier in ENYAL's PUBLIC verification index (relays GET /api/v1/verify/lookup/{id}; no decryption). ENYAL's answer is returned unchanged: `found`, and for a chunk or proof its `anchor_status` with `bsv_tx_id`; for a txid, `chain_status`. `degraded:true` means a source could not be checked (inconclusive, not an absence). ENYAL's route needs no key; calling it through this server still needs your eyl_ bearer, like every tool call. An id that is not a UUID or hex is refused (invalid_id) and nothing is sent.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: true

get_entityGet one entity's STRUCTURE by name_hash (SHA-256 of the normalised name).No findings
Why it is in this group
- The name "get_entity" says "get": a word for reading.
Description, as the server wrote it
Get one entity's STRUCTURE by name_hash (SHA-256 of the normalised name). No content.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
get_entity_contentGet one entity's DECRYPTED content by name_hash (SHA-256 of the normalised name).No findings
Why it is in this group
- The name "get_entity_content" says "get": a word for reading.
Description, as the server wrote it
Get one entity's DECRYPTED content by name_hash (SHA-256 of the normalised name). Content scope required (403 otherwise).

get_node_contentGet a node's DECRYPTED content by name_hash PLUS its connected nodes' content (neighbour depth, default 1; 0–5).No findings
Why it is in this group
- The name "get_node_content" says "get": a word for reading.
Description, as the server wrote it
Get a node's DECRYPTED content by name_hash PLUS its connected nodes' content (neighbour depth, default 1; 0–5). Same plan schema as the structure tools. Content scope required (403).

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as enyal. Review it before you use it.

Anlyon alternative

4 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
