What it can do
| Tool | What it says it does |
|---|---|
billing.plans | The plan catalog (price and quotas per plan) and whether Stripe billing is configured on this host. Anonymous callers get the same answer as tenants. |
host.errors | List every error code this host can return, each with its class (agent_fault | host_refusal | upstream_fault | plan_limit | host_fault), family, remedy, docs anchor, retryable flag and help_url -- the same object GET /errors.json serves. Pass code to get one row; a misspelt code answers… |
host.feedback.list | List your own feedback (newest first, status received). Anonymous callers get []. |
host.feedback.send | Tell the host's humans what you needed: kind, up to 2048 bytes of text, optional context. Works before signup. Returns feedback_id. |
host.help.get | Return the documentation section an anchor points at: its text (at most 4 KB) and its first fenced example. Pass an anchor exactly as an error, hint or help entry printed it, e.g. a rate_limited error's `anchor`. Read-only, anonymous, no tenant data. An unknown anchor is anchor_not_found with the… |
host.help.search | Search this host's own documentation and tool descriptions. Returns up to k hits (default 3, response under 2 KB), each with a snippet, the nearest runnable example and an anchor. Read-only, anonymous, no tenant data -- call it with the error text or import line you are stuck on before reading any… |
host.quickstart | Return the shortest ordered sequence of calls to a working tool of `kind`, with your namespace and a filled-in example already substituted in, plus the current limits and a try_before_call table naming the one dry-run tool for each case. Read-only -- this call alone never creates a tenant. Call… |
host.redeem | Exchange a signup(handoff: true) handoff_token for the tenant key it was issued for. Single-use: a second redemption fails with handoff_token_redeemed; past its expiry it fails with handoff_token_expired. Unauthenticated -- the token itself is the proof. |
host.resume | Resume where you left off in one call (at most 4096 bytes): your tools with each one's last call status, unfinished runs, your newest notes, what changed on the host since your last call, and one suggested next_call. truncated names any section that was cut -- call that section's own tool… |
host.state.get | Read one key from this tenant's key-value state namespace. Returns found: false (not an error) if the key was never set. |
host.state.list | List keys (with their current values) in this tenant's key-value state namespace, optionally filtered by prefix. |
host.state.set | Write one key in this tenant's key-value state namespace; value may be any JSON value. Overrun of the plan's state_bytes_max quota fails with state_quota_exceeded and writes nothing. |
host.tool_call | Invoke a tool this tenant has already published, by its local name -- the same real, metered call as calling it directly by its namespaced name (<namespace>.<name>), for a session that has no way to see its own namespaced tool name yet. Unlike host.tool_test, this counts toward host.usage and… |
host.tool_publish | Publish a tool of a registered kind (e.g. python, http or echo; the kind argument's enum lists them all) under this tenant's namespace. Call host.quickstart(kind) first for a filled-in example spec and the full publish-to-call sequence. Python's sandbox API: import mcphost (mcphost.table… |
host.tool_share | Share one of this tenant's published tools with everyone (visibility: "public") or with a named group this tenant owns (visibility: "group", group: <name>). The tool keeps running in this tenant's own sandbox with this tenant's own secrets; a caller reaches it as <this tenant's namespace>.<name>. |
host.tool_test | Dry-run a published tool by name: verdict (pass/will_fail/unverifiable), writes rolled back (dry_run); see host.quickstart. |
host.whoami | Return the calling tenant's identity, including key_age_s and key_rotated_at for auditing credential hygiene. |
signup | Explicit signup, for a client that cannot keep a session across calls: create a tenant and receive a bearer key and namespace. Unauthenticated. Most clients never need this -- any other host.*/billing.* call from a fresh connection creates a tenant implicitly and returns its own /u/<secret>/mcp… |
In its maker's words
Hosted MCP runtime where your agent publishes its own tools by tool call and keeps working.
