Overview

AI-generated overview

LinkCensus is a hosted MCP endpoint for finding related domains and shared backlinks, with read-only lookups of a domain's neighborhood.

What you can do
Look up related domains and shared backlinks for a given domain through the hosted LinkCensus service, using read-only tools over the same REST client as the CLI. The README describes three read-only stdio tools in the local package, but the manifest lists no tools for the hosted endpoint. Free access covers a small monthly number of neighborhood lookups per account, with a limited number of candidate rows per lookup. Edition and domain-resolution requests do not spend monthly neighborhood attempts but still require authentication.
When to use it
Useful when you want an assistant to explore a domain's neighborhood, related domains and shared backlinks for research or competitive analysis, and you already have a LinkCensus account and API key.
Requirements
A remote Streamable HTTP endpoint at linkcensus.com, reached with a client that supports a custom Authorization header. A personal LinkCensus API key, sent as an Authorization bearer header, is required. The local stdio package is a separate source package that is not publicly installable from a package index in this release candidate.
Before you install
The API key is a personal secret; keep it out of arguments, public examples and repository files, and do not post credentials or private responses. Lookups count against a shared monthly free quota across REST, CLI and MCP, and rotation does not reset it. Candidate domains are not independently confirmed competitors, so retain edition, provenance, truncation and quota notes. No request triggers a crawl or retries automatically.

Installation

In SourceWeft

  1. Open LinkCensus 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/io.github.pucilpet%2Flinkcensus-mcp/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

README

LinkCensus agent clients

Release-candidate source for the LinkCensus REST client/CLI and local stdio MCP gateway. This export contains only the two client packages, their source, tests, notices, license and release metadata. It contains no application server, graph, customer state, deployment configuration or repository history. The public source repository is linkcensus-agent-clients. The hosted MCP endpoint is live at https://linkcensus.com/mcp using Streamable HTTP. Sign in at your account and configure your personal key in a private Authorization: Bearer YOUR_LINKCENSUS_API_KEY header. Use a client that supports a custom Authorization header. See the MCP setup guide and API documentation.

Public PyPI package releases remain pending; the local package versions below are separate from hosted availability.

Packages

PackageVersionPurpose
linkcensus-client0.1.0Standard-library REST client and linkcensus CLI
linkcensus-mcp0.1.0Three read-only stdio tools over the same REST client

Free access includes 5 neighborhood lookups per account per UTC calendar month, with up to 5 candidate rows per lookup. REST, CLI and MCP share that counter; rotation does not reset it. Editions and domain resolution do not spend monthly neighborhood attempts but still require authentication and execution admission. Candidates are not independently confirmed competitors; retain edition, provenance, truncation and quota notes. The website ledger and VerifiedPricing budgets are separate. No request triggers a crawl or retries automatically.

The hosted service uses personal bearer keys. The local stdio gateway uses HTTPS REST and remains available as a separate source package. Linux/Python 3.12 is tested for local stdio; other source-supported Python 3.10+/POSIX combinations need acceptance, and Windows is unsupported. See each package's transport limits.

Candidate installation

Public package-index installation is not available from this release candidate. A placeholder wheelhouse path below is not evidence of a public package or downloadable bundle. Use a separately reviewed isolated environment and complete wheelhouse:

sh
python3 -m venv .venv-linkcensus.venv-linkcensus/bin/python -m pip install --no-index \  --find-links /path/to/reviewed-wheelhouse \  linkcensus-client==0.1.0 linkcensus-mcp==0.1.0 mcp==2.3.0.venv-linkcensus/bin/linkcensus --version.venv-linkcensus/bin/linkcensus-mcp --version

Provide a key through the private environment or owned regular mode-0600 configuration. Never put it in arguments, public examples or repository files. linkcensus configure saves an already provisioned LINKCENSUS_API_KEY; it does not sign in or issue keys. See client setup and the secret-free launcher template.

Local source checks

No installation or backend is needed for the client package's bounded unit and loopback tests:

sh
cd packages/linkcensus-clientPYTHONDONTWRITEBYTECODE=1 PYTHONPATH=src python3 -m unittest discover -s tests -v

For gateway checks, use a reviewed separate environment with the exact pinned SDK and both distributions installed; add the two source directories to its PYTHONPATH, then run the gateway tests. Tests use synthetic credentials/fixtures, not production. The initial SDK installation and public-index clean-install acceptance are separate operations, not test side effects.

Distribution and security

The hosted endpoint is listed in the official MCP Registry. server.hosted.json contains the published manifest. The separate PyPI/stdio manifest remains a distribution candidate; public package-index publication and installation are pending.

Do not post credentials or private responses. Use private GitHub vulnerability reporting for security issues. This feature is enabled; no response-time commitment is promised. See the client policy and gateway policy.

Both packages retain their existing MIT licenses, copied unchanged to the root. Original VerifiedPricing and LinkCensus copyright notices are preserved. The gateway provenance note records the licensed transport adaptation; no new copyright attribution is invented.

EXPORT_ALLOWLIST.json names every exported file. EXPORT_MANIFEST.json binds all payload files except itself by SHA-256 and byte length; the private review receipt separately records the manifest's hash. No secret scan establishes that credentials can never exist: review the exact candidate and artifact before publication, and retain any reported synthetic-test classification.

Tools

0
This server asks for a credential such as an API key, so SourceWeft could not read its tools without one and has not indexed them.
