Installation

In SourceWeft

  1. Open Seb Labs in the dashboard and add it to a workspace.
  2. Connect Authorization token credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.seblabs%2Fseblabs/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Tools

seb_demo

Preview a free illustrative decision

Use for a free connection/interface check or a fixed example of enterprise, finance, robotics or handoff decisions. Returns labeled illustrative probabilities, never live inference. No account token is required. Use a paid tool to judge your own input.

Parameterspresetrequired

seb_decide

Make typed evidence checks and rubric judgments

Use for evidence/claim support checks, binary screening, rubric scoring, or several related judgments on one text state. Supply 1–10 named questions: choice has 2–20 option keys mapped to descriptions (or null); noul asks a precisely worded positive/yes proposition and returns its probability in [0,1]; score has 2–5 rubric levels ordered low to high and returns a 0-based expected ordinal score with probabilities. Returns typed answers and metered usage without a prose explanation. Include all needed facts; no browsing or retrieval. Requires a funded account token; shared state is metered separately for each question.

Parametersstaterequiredquestionsrequired

seb_fin_analyze

Use an enabled dedicated financial specialist

Use only for entitled accounts with an enabled dedicated Seb-9B-Fin backend, to judge financial language or supplied point-in-time market context with the same choice/noul/score schema. The public general-model endpoint does not currently enable this specialist. Returns typed model estimates, not investment advice, a forecast guarantee or an executed trade. Missing finance configuration/entitlement returns an error; never assume general-model fallback. Paid input-token metering applies when enabled.

Parametersstaterequiredquestionsrequired

seb_route

Route or classify text among labels

Use for fast single-label classification or routing: ticket triage, intent/topic/sentiment labels, selecting a tool or workflow, guardrail categories or an escalation decision. Supply the relevant context and 2–20 unique option labels (up to 80 characters each); add an unclear/escalate label if appropriate. Returns the selected label and probabilities for every option. No explanation or downstream action. Model-estimated probabilities can be wrong. Requires a funded account token; charges input tokens.

Parameterscontextrequiredoptionsrequired

seb_batch_decide

Batch-label independent items

Use to classify, screen, triage, rank by an explicit rubric, or bulk-label up to 100 independent text states with the same 1–10 typed questions. Each result retains its input index and its own success/error; up to four items run concurrently. Inspect all per-item errors and retry failed items only, not the whole successful batch. Input limits and the account question-rate limit still apply. Requires a funded account token; each successful item/question charges model input tokens. Not a bulk discount or a single flat-priced request.

83% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
