MCP tools · 38 exposed · ~2,255 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
board_assign ~101

Assign a task to an agent and notify them — records the assignee AND leaves a 'please look at task #N' message in that agent's inbox. Passive: the board records the ask; the agent reads its inbox and decides to act. Never launches the agent.

Common questions

What is the io.github.octoryn/octopus-blackboard MCP server?

io.github.octoryn/octopus-blackboard is an MCP server listed in the public MCP registry as io.github.octoryn/octopus-blackboard. Shared memory & coordination for AI coding agents, a blackboard, not an orchestrator. This page covers its npm package (octopus-blackboard).

Is the io.github.octoryn/octopus-blackboard MCP server safe to use?

io.github.octoryn/octopus-blackboard scores 94 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the io.github.octoryn/octopus-blackboard MCP server expose?

io.github.octoryn/octopus-blackboard exposes 38 tools: board_status, board_timeline, board_note, board_claim, board_task_define, and 33 more. Their descriptions and schemas cost roughly 2,255 tokens of context every time the server is loaded.

Is the io.github.octoryn/octopus-blackboard MCP server still maintained?

io.github.octoryn/octopus-blackboard is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the io.github.octoryn/octopus-blackboard MCP server under?

io.github.octoryn/octopus-blackboard declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
