feat(connectors): add sellmycompanydata connector (2 endpoints)

Sell My Company Data (https://sellmycompanydata.com) works out an indicative range for what a company's operational records (chat, CRM, support tickets, docs, code, email, projects, finance) could be worth when licensed for AI training and evaluation. It works from summary figures only: counts, date ranges and product names, never content or personal data.

This PR adds the two read-only tools of its public, keyless MCP server (https://sellmycompanydata.com/mcp, Streamable HTTP, stateless) as a Monid connector.

Endpoints

Id	MCP tool	What it does
`sellmycompanydata#assessment-checklist`	`assessment_checklist`	What to count in each kind of system before estimating. No parameters
`sellmycompanydata#estimate-data-value`	`estimate_data_value`	Indicative licensing range from headcount, founding year, region and systems, with caveats, what would raise it, and a link to the website calculator with the same figures

Category: funding-data (existing leaf: valuations and deal activity; no taxonomy change).

How it is built

MCP, one pinned tool per endpoint. Both endpoints POST to /mcp, and each pins its own tools/call name in input.toRequest. Callers pass only the tool's arguments, so a caller cannot reach another tool on the server. The server is stateless (no session, no initialize needed).
Read-only. The server's third tool, request_offer, is not included: it submits the owner's contact details to a human team and sends email and Slack notifications. The estimate's next_step field names that tool, so the endpoint's fromResponse replaces that one field with a pointer to estimate_url (where a person can ask for a review). Every other field passes through as the server sent it, and a test pins that.
Free and keyless. UsageModelKind.FREE, an empty credential shape (z.object({})) and an identity auth.inject, the same shape as the pending salesbook connector (#184). A test pins the egress: URL, POST, three headers, the pinned JSON-RPC body.
In-band failures settle at zero. Streamable HTTP answers failures with HTTP 200. A provider lifecycle.start lifts JSON-RPC errors, isError tool results and malformed or mismatched-id envelopes to a synthesized 422 (providerHttpStatus keeps the real 200), the same approach as the pending mermail connector (#192). fromError digests them to { message, code?, raw }, with the server's own reason as message.
Input mirrors the server's published tools/list inputSchema (server v1.1.0, read 2026-10-29): strict at both levels as published, optionality only, no defaults. The server also caps founding and system years at the current year, which JSON Schema cannot express, so that check stays on the server and comes back as a zero-billed provider error.
No engine, schema, preset or category change. ENGINE_VERSION untouched. The record is in openspec/changes/add-connector-sellmycompanydata/.

Fixtures and tests

Four fixtures recorded from the public server on 2026-10-29 (made-up figures, no personal data, no headers kept): the checklist, a qualifying estimate, a below-bar estimate and an in-band refusal. They were captured with curl rather than deno task record, so a test asserts each recorded request body is exactly the one the connector sends.
provider.test.ts holds the compiled-shape test (once per provider). Each endpoint has its own endpoint.test.ts, with shared helpers in test-support.ts: happy replays, provider errors at zero usage (the in-band refusal, JSON-RPC / HTTP / malformed envelopes, a non-JSON 500), the schema gate with passing near-twins (the checklist pins that it takes no input), pinned egress, a zero pre-run estimate, and live runs gated on SELLMYCOMPANYDATA_LIVE=1 (keyless, so liveSkip has no credential to gate on).
deno task check && deno task test pass with no network: 1312 passed, 0 failed, 223 ignored. That includes the 14 new tests here; the 2 gated live runs are among the ignored. Monid's own ci workflow on this head (af5e326), run in our fork because outside PRs wait for approval: https://github.com/jamesrowdyy/monid/actions/runs/40821234723. deno fmt --check and deno lint on the connector are clean.
connectors/ids.lock.json: adds the two ids only.

Walkthrough

Adds a keyless, free Sell My Company Data connector with two read-only MCP endpoints: an assessment checklist and a data-value estimate. The estimate endpoint validates input against a strict schema and directs next_step to estimate_url. The provider handles MCP errors and malformed responses as provider errors. Recorded fixtures and tests cover requests, validation, successful responses, and error cases.

Priority: Normal

Merge Risk: Minimal · up to af5e3

The previously identified test-layout and response-handling concerns are addressed; no outstanding issue identified here prevents merging after normal checks.

Full details: Title check

Explanation

The title names the change: a new sellmycompanydata connector with two endpoints. The changeset adds that connector, with the two endpoints assessment-checklist and estimate-data-value, fixtures, and tests. The title states the main change and does not mention the excluded request_offer tool, which the title does not need to cover. The title follows conventional commit form and is 63 characters, well under typical limits.

67-72: Trivial · Maintainability & Code Quality · Low value

Drop the unreachable shape guard.

The caller rejects invalid structuredContent before fromResponse. The TypeScript convention also treats this redundant null check as a defect. Import Json as a type and cast the existing declaration.

Suggested fix

-import { defineEndpoint } from "@shared/core";
+import { defineEndpoint, type Json } from "@shared/core";
...
             const structured = utils.json.get(
                 data.output,
                 "$.result.structuredContent",
-            );
-            if (
-                structured === null || typeof structured !== "object" ||
-                Array.isArray(structured)
-            ) {
-                return structured;
-            }
+            ) as Record<string, Json>;

Remove the redundant shape guard in the `fromResponse` flow and import `Json` as
a type from `@shared/core`. Cast the existing `utils.json.get` result to
`Record<string, Json>` so the caller’s validation remains the source of truth.

- Line 1: Split the endpoint-specific tests from provider.test.ts into separate
endpoint.test.ts files for assessment-checklist and estimate-data-value. Move
the checklist replay, pinned-egress, and zero-usage-estimate tests to the
assessment-checklist suite, and the estimate replay, refusal, envelope,
schema-gate, and egress tests to the estimate-data-value suite; keep the
compiled-shape testBundle test in provider.test.ts.
