SINT Protocol
Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| SINT_MCP_PORT | No | Port for SSE transport | |
| SINT_MCP_CONFIG | No | Optional path to sint-mcp config file | |
| SINT_MCP_POLICY | No | Default policy mode | |
| SINT_MCP_TRANSPORT | No | Transport mode | |
| SINT_AGENT_PRIVATE_KEY | No | Optional Ed25519 private key | |
| SINT_MCP_APPROVAL_TIMEOUT | No | Approval timeout in milliseconds |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| sint__statusA | Show SINT MCP status: connected servers, agent identity, queue size, and system health |
| sint__serversA | List all downstream MCP servers with connection status, tool counts, and health |
| sint__whoamiA | Show current agent identity: public key, active token, session info |
| sint__pendingA | List all pending approval requests awaiting human review |
| sint__approveC | Approve a pending escalated action by its request ID |
| sint__denyB | Deny a pending escalated action by its request ID |
| sint__auditB | Query the SINT evidence ledger for recent decisions and events |
| sint__add_serverB | Dynamically add a new downstream MCP server at runtime |
| sint__remove_serverC | Remove a downstream MCP server by name |
| sint__issue_tokenC | Issue a new capability token with restricted scope (admin). Returns tokenId on success. |
| sint__revoke_tokenC | Revoke an active capability token by its ID (admin) |
| sint__interface_statusA | Return current operator interface state: mode, listening/speaking flags, active HUD panels, memory context size, and session ID |
| sint__recall_memoryB | Search the memory bank for entries matching a query string. Returns matching entries as JSON. |
| sint__speakC | Schedule TTS voice output to the operator with a configurable priority level |
| sint__show_hudB | Update a HUD panel with new data. Emits an operator.hud.updated event. |
| sint__store_memoryC | Store an entry in the memory bank with optional tags and persistence |
| sint__notifyC | Send a proactive notification to the operator, optionally with an actionable button |
| sint__interface_modeB | Change the operator interface display mode: hud, compact, voice-only, or silent |
| sint__delegate_to_agentA | Issue an attenuated capability token to a sub-agent, granting it a reduced tool scope. Depth is parent.depth + 1; max depth 3. Returns the new tokenId. |
| sint__list_delegationsB | List the active delegation tree rooted at the current operator token. Returns a JSON array of DelegationNode objects. |
| sint__revoke_delegation_treeA | Revoke an entire delegation subtree rooted at the given tokenId. All descendant tokens are cascade-revoked. |

TDQS
Scored across 21 tools
Every tool has a clearly distinct purpose with no ambiguity. Tools like sint__approve and sint__deny handle opposite actions, sint__audit and sint__pending cover different review aspects, and sint__store_memory and sint__recall_memory manage separate memory operations. The descriptions make each tool's unique role immediately apparent.
All tools follow a consistent 'sint__verb_noun' pattern throughout, with clear and descriptive names like sint__add_server, sint__remove_server, and sint__list_delegations. The naming convention is uniform, using snake_case and prefixed verbs that accurately reflect each tool's function without deviation.
With 21 tools, the count is slightly high but reasonable for the server's purpose of managing MCP servers, operator interfaces, and security capabilities. It covers a broad scope including server management, delegation, approval workflows, and memory operations, though it could be streamlined without losing essential functionality.
The tool set provides comprehensive coverage for the SINT Protocol domain, including full lifecycle management for servers (add, remove, list), delegation (issue, list, revoke), approval workflows (pending, approve, deny), memory operations (store, recall), and operator interface control. No obvious gaps exist; agents can perform all expected operations without dead ends.
