I make SpecStream, the live web data engine, and this PR adds it as an MCP vendor. Today the agent researches one company or person at a time through Context.dev and Perplexity. SpecStream builds a whole dataset from the live web in one request and keeps it current, so the agent gets every matching company or person at once, with the source URL and read time on every value. The reasoning is in the ADR in the first commit, adrs/specstream-mcp-vendor.md. The second commit is the code.

The diff

• packages/mcp-integrations/src/vendors/specstream.ts, new, same shape as Linear and Notion
• one line in vendors/index.ts, one in the slug list in test/catalog.spec.ts, and one added test
• the vendor name in docs/connections.md

Read-only access asks for specs:read, finds:read, projects:read and account:read. Read-write adds specs:write, finds:write and finds:spend. riskyTools lists the tools that spend or send: authorize_capacity_work, quote_capacity_work, schedules, destination syncs, share and export.

I didn't add a logo, so the initials fallback in EntityLogo/ProviderMark applies. docs/connections.md calls that the correct behaviour.

Checks (Linux server, oven/bun:1.4)

• bun run check-types in packages/mcp-integrations: clean
• bunx biome check packages/mcp-integrations: clean after format
• bun test in the package: 13 pass, 0 fail
• bun run lint:slop on the repo: 0 warnings, 0 errors
• your McpOAuthClient.discover against the live SpecStream endpoints: passes (issuer https://specstream.ai, registration endpoint present, S256)

Not run: the apps/api and apps/agent integration tests, which need the Postgres from docker compose, and the full turbo pipeline.
