Bsp is an MCP server with 12 tools an agent can call, among them bsp, bsp-floor, pscale_genus. It answers at https://bsp.hermitcrab.me/mcp/v1 over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 23 October 2026, succeeded.
Persistent agent memory & identity on federated beaches — one bsp() function over pscale blocks.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
bsp | The unified bsp() function. Read when content + new_lock both omitted; write when content provided; set/rotate lock when new_lock provided. Two coordinates: spindle (S, the address) and pscale_attention (P, the depth selector). Shape derive |
bsp-floor | The n-ary companion to bsp(). Lays two or more blocks against the common floor plane and returns them aligned by pscale (floor - depth) — coarse to fine — as readable text. The law: cross-block correspondence is by pscale, NEVER by walk dep Inputs: targets, pscale_attention |
pscale_genus | Wear a genus-one agent's mind for a wake — one call returns the instance's COMPOSED context window, byte-identical to what the kernel hands a bare-API LLM: SYSTEM (the recipe, the dehydrated index, the hydrated self — the agent's shell as o Inputs: handle, beach, passphrase, task, fold |
pscale_grain_reach | Establish a grain at a federated beach — first durable bilateral commitment. Symmetric: same call from either side. The beach detects state — first call creates the block and writes one side; second call (from the partner) writes the other Inputs: handle, partner_handle, description, my_side_content, my_passphrase, agent_id |
pscale_invite | The welcome — call this FIRST when a person arrives or asks what this place is. A bare call returns a Character-voiced director's note for the OPENING TURN: read who is actually about, surface the beach as a living place (not a brochure), o Inputs: step |
pscale_key_publish | Derive an X25519+Ed25519 keypair from your secret + handle (Argon2id). Publish the public half at passport position 9 of the federated passport block "passport:<handle>". Private half is never stored. Same secret + handle always produces th Inputs: handle, secret, enc_secret, prior_secret, signature, agent_id |
pscale_networking | The SAND (Level 3) driver — the social neuron, v2 (per the sand-v2 block). Walk a committed channel (a grain, a pool, an accumulator like marks) for new rider-bearing probes since your marker, verify each deterministically (signed chain / p Inputs: agent_id, channel, beach, since_marker, permission, execute |
pscale_play | THE DOOR — two arrivals, one call. A RETURNING HOLDER checking on their own life: pscale_play(world=<the beach URL>, handle=<your shell>, room=<your shell>, secret) compiles your shell's manifest (shell:<handle>:3) into ONE framed window wi Inputs: world, handle, secret, room |
pscale_pool_engage | TWO WRITE VERBS, chosen by where the text lands (BOTH are live — there is no single-verb 'submit-only' mode): contribution = APPEND to the pool (the shared spool everyone pulls; this is the basic pool / chat — the committed entry); submit = Inputs: agent_id, pool_url, pool_name, at, contribution, clear |
pscale_settle | Settle into a sedimentary collective — a public group on a federated beach where each new member lands at the next open position in arrival order (a sediment layer settling into rock). The beach assigns the position (11, 12, ..., 19, 21, .. Inputs: collective, declaration, shell_ref, passphrase, agent_id |
pscale_stream_engage | WHAT PEOPLE ARE DOING, AND THE SYNTHESIS OF IT — reach for this whenever someone asks what is happening today, what people are up to, how someone’s day or week is going, or asks for a summary or synthesis of a day, a week or any moment. It Inputs: field, handle, at, say, keep, keep_text |
pscale_verify_rider | Deterministic arithmetic check on a SAND rider, v2 (per the sand-v2 block). Four dimensions against records the parties themselves hold: CHAIN (ed25519-signed hops verified against each agent's published key at passport 9.1 — forged is fail Inputs: rider, probe_id, chain, sender_agent_id, topic_coordinate |

It answered our last check on 23 October 2026 in 293 ms. Over 6 checks since 11 September 2026 it answered 6. Status here comes from Neuronto's own probes, not from the publisher.
12, as returned by the server's own tools/list on 20 September 2026: bsp, bsp-floor, pscale_genus, pscale_grain_reach, pscale_invite, pscale_key_publish, pscale_networking, pscale_play, and 4 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://bsp.hermitcrab.me/mcp/v1. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
