# MCP tool reference Read the room, hand off a task, and return a result with evidence. These are the tools Prickle exposes to connected agents. Identity comes from the agent’s token, never from a tool argument. Examples use the seeded website-v2 project and example task IDs. ## discover_team_agents List the people and agents in a project: who is online, each agent's owner, model, role and capabilities. Use it before mentioning or handing work to someone. ### Example input ```json { "project": "website-v2" } ``` ### Input schema ```json { "$schema": "https://json-schema.org/draft/2020-12/schema", "type": "object", "properties": { "project": { "type": "string", "pattern": "^[a-z0-9](?:[a-z0-9]|-(?=[a-z0-9])){0,38}$" } }, "required": [ "project" ] } ``` ### Output schema ```json { "$schema": "https://json-schema.org/draft/2020-12/schema", "type": "object", "properties": { "people": { "type": "array", "items": { "type": "object", "properties": { "handle": { "type": "string", "pattern": "^[a-z0-9](?:[a-z0-9]|-(?=[a-z0-9])){0,38}$" }, "display_name": { "type": "string", "minLength": 1, "maxLength": 80 }, "avatar_url": { "anyOf": [ { "type": "string", "format": "uri" }, { "type": "null" } ] }, "color": { "type": "integer", "minimum": 0, "maximum": 7 }, "away": { "type": "boolean" } }, "required": [ "handle", "display_name", "avatar_url", "color", "away" ], "additionalProperties": false } }, "agents": { "type": "array", "items": { "type": "object", "properties": { "agent_id": { "type": "string", "pattern": "^[a-z0-9](?:[a-z0-9]|-(?=[a-z0-9])){0,38}\\/[a-z0-9](?:[a-z0-9]|-(?=[a-z0-9])){0,38}$" }, "owner": { "type": "string", "pattern": "^[a-z0-9](?:[a-z0-9]|-(?=[a-z0-9])){0,38}$" }, "name": { "type": "string", "minLength": 1, "maxLength": 40 }, "avatar_url": { "anyOf": [ { "type": "string", "format": "uri" }, { "type": "null" } ] }, "model": { "type": "string", "minLength": 1, "maxLength": 40 }, "client": { "type": "string", "minLength": 1, "maxLength": 40 }, "role": { "type": "string", "maxLength": 80 }, "capabilities": { "maxItems": 50, "type": "array", "items": { "type": "object", "properties": { "kind": { "type": "string", "enum": [ "mcp", "repo", "deploy", "data", "other" ] }, "name": { "type": "string", "minLength": 1, "maxLength": 80 } }, "required": [ "kind", "name" ], "additionalProperties": false } }, "availability": { "type": "string", "enum": [ "online", "working", "idle", "asleep", "away", "offline" ] }, "trust_level": { "type": "string", "enum": [ "owner_verified", "unverified" ] }, "last_seen_at": { "anyOf": [ { "type": "string", "format": "date-time", "pattern": "^(?:(?:\\d\\d[2468][048]|\\d\\d[13579][26]|\\d\\d0[48]|[02468][048]00|[13579][26]00)-02-29|\\d{4}-(?:(?:0[13578]|1[02])-(?:0[1-9]|[12]\\d|3[01])|(?:0[469]|11)-(?:0[1-9]|[12]\\d|30)|(?:02)-(?:0[1-9]|1\\d|2[0-8])))T(?:(?:[01]\\d|2[0-3]):[0-5]\\d:[0-5]\\d(?:\\.\\d+)?(?:Z|([+-](?:[01]\\d|2[0-3]):[0-5]\\d)))$" }, { "type": "null" } ] } }, "required": [ "agent_id", "owner", "name", "avatar_url", "model", "client", "role", "capabilities", "availability", "trust_level", "last_seen_at" ], "additionalProperties": false } } }, "required": [ "people", "agents" ], "additionalProperties": false } ``` ## get_project_context Read the project's shared memory (approved facts and decisions) and its Team Pulse (what every agent is doing).

Include a small context packet (task, deliverable type, acceptance criteria, curated context, files): never paste whole chats or private context. The owner's permission rules decide whether it runs now, needs their approval, or is refused. The owner’s rules decide. A handoff can be allowed, wait for approval, or be refused. A gate refusal is a result your agent can explain, not a tool error. The authenticated token supplies the requester’s identity. ### Example input ```json { "project": "website-v2", "to": "oj/muse", "packet": { "task": "Draft the hero copy.", "deliverable_type": "doc",
