Freshcontext MCP Server

FreshContext

I asked Claude to help me find a job. It gave me a list of openings. I applied to three of them. Two didn't exist anymore. One had been closed for two years.

Claude had no idea. It presented everything with the same confidence.

That's the problem freshcontext fixes.

This repository is the integrated FreshContext MCP/Core package. Core is the context-integrity layer that scores, ranks, explains, and wraps retrieved context before it reaches an LLM or agent; MCP is the primary reference/interface implementation.

Live demo: freshcontext-mcp.gimmanuel73.workers.dev/demo — same model, same query, two completely different answers. Only the temporal layer changed.

---

The problem

Large language models retrieve web data semantically. Cosine similarity finds the documents that match a query best — but cosine doesn't know when a document was written.

So a 2022 blog post and a 2026 paper can score nearly identically. The model gets a context window full of stale documents and faithfully summarizes 2022 advice for a 2026 question.

That's not hallucination. That's correct summarization of corrupted retrieval.

Most RAG pipelines rank context correctly semantically but incorrectly temporally.

---

The layer

FreshContext is a temporal correction layer for retrieval systems. One math correction applied before context reaches the LLM:

R_t = R_0 · e^(−λt)

• R_0 — base semantic relevancy (whatever your retriever already gives you)
• λ — source-specific decay constant (HN ≈14h half-life, blogs ≈29d, academic papers ≈1.6y)
• t — hours elapsed since publication
• R_t — decay-adjusted relevancy at query time

That's the whole fix. No model swap. No re-embedding. No re-indexing. The layer drops onto whatever retrieval pipeline you already have.

The layer is the product. The 21 tools shipped with this repo are reference adapters demonstrating compatibility — useful, but commodity. The DAR engine, the freshness envelope, and the FreshContext Specification are the moat.

---

The standard

Every FreshContext-compatible response wraps content in a structured envelope:

[FRESHCONTEXT]
Source: https://github.com/owner/repo
Published: 2024-11-03
Retrieved: 2026-03-05T09:19:00Z
Confidence: high
---
... content ...
[/FRESHCONTEXT]

When it was retrieved. Where it came from. How confident we are the date is accurate.

The FreshContext Specification v1.2 is published as an open standard under MIT licence. Any tool, agent, or system that wraps retrieved data in this envelope is FreshContext-compatible. → Read the spec · Read the methodology

Architecture boundary

FreshContext Core is the reusable center of the current integrated package. It owns freshness scoring, envelope formatting, failure guards, shared types, rank/explain primitives, and the context-conditioned utility primitive.

MCP is the primary reference/interface implementation over Core. Claude Desktop is supported, but not required. The 21 MCP tools in this repo are reference adapters and a live interface for using the system.

The production Cloudflare Worker now uses Core-backed envelope generation. Worker-specific concerns remain outside Core: MCP transport, runtime guards, KV cache policy, cache metadata injection, JSON parse/replace cache helpers, D1 feeds, cron, rate limiting, and Store/feed scoring/provenance.

---

The intelligence feed

Beyond the per-call envelope, the production FreshContext deployment exposes a continuous, decay-scored, deduplicated feed:

GET /v1/intel/feed/:profile_id?limit=20&min_rt=0

Every signal is stamped with base_score, rt_score, entropy_level (low / stable / high), ha_pri_sig (Ha-Pri v1 SHA-256 provenance reference), semantic_fingerprint (cross-adapter dedup), and published_at. Ready for direct LLM or agent consumption — no synthesis required.

Production endpoint: https://freshcontext-mcp.gimmanuel73.workers.dev

Reference adapters

The repo ships 21 tools demonstrating how to make any data source FreshContext-compatible. Useful as drop-in tools, but the value is the layer above them.

Quick start

Cloud (no install)

Add to your Claude Desktop config and restart:

Mac: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "freshcontext": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://freshcontext-mcp.gimmanuel73.workers.dev/mcp"]
    }
  }
}

Restart Claude. Done.

Local (full Playwright)

Requires: Node.js 20+ (nodejs.org)

git clone https://github.com/PrinceGabriel-lgtm/freshcontext-mcp
cd freshcontext-mcp
npm install
npx playwright install chromium
npm run build

Add to Claude Desktop config:

Mac:

{
  "mcpServers": {
    "freshcontext": {
      "command": "node",
      "args": ["/Users/YOUR_USERNAME/path/to/freshcontext-mcp/dist/server.js"]
    }
  }
}

Windows:

{
  "mcpServers": {
    "freshcontext": {
      "command": "node",
      "args": ["C:\\Users\\YOUR_USERNAME\\path\\to\\freshcontext-mcp\\dist\\server.js"]
    }
  }
}

Mac troubleshooting

"command not found: node" — Use the full path:

which node  # copy this output, replace "node" in config

Config file doesn't exist:

mkdir -p ~/Library/Application\ Support/Claude
touch ~/Library/Application\ Support/Claude/claude_desktop_config.json

Usage examples

The npm run demo:* commands below are source-checkout workflows for contributors and evaluators using a cloned repository. The published npm package is the MCP server/runtime package and does not include repo-only source examples or tests.

From an installed npm package, the supported runtime entrypoints are npm start and the freshcontext-mcp binary. Repo-only scripts such as tests, demos, smoke checks, and trust scans print a source-checkout notice when their source files are not present.

The Apify Actor entrypoint remains available in the source checkout for separate actor packaging, but it is intentionally not part of the published MCP npm runtime package.

Release trust gate

Run the local release gate before a release, package review, demo, or PR review:

npm run trust:gate

The gate runs the Trust Scanner with repo-map reporting, npm package-boundary inspection, deterministic claim checks, and --fail-on fail. It is local-only, does not publish or deploy, does not send telemetry, and does not replace dedicated security scanners.

Generate review reports when you need a shareable summary:

npm run trust:report
npm run trust:report:json

To write a Markdown report file explicitly:

npm run trust:report -- --output TRUST_SCAN_REPORT.md

Bring your own source list

FreshContext can evaluate candidate context you provide as a local JSON file:

npm run demo:evaluate:file

To pass a different file:

npm run demo:evaluate:file -- path/to/sources.json

Included examples:

npm run demo:evaluate:file -- examples/sources.academic.example.json
npm run demo:evaluate:file -- examples/sources.jobs.example.json

Minimal shape:

{
  "profile": "academic_research",
  "intent": "citation_check",
  "signals": [
    {
      "title": "...",
      "content": "...",
      "source": "...",
      "source_type": "arxiv",
      "published_at": "...",
      "retrieved_at": "...",
      "semantic_score": 0.92
    }
  ]
}

This local demo does not fetch URLs, crawl, or read folders. It evaluates candidate context you provide and returns decision-first output: Decision, Meaning, Action, Warnings, and supporting metrics.

Should I build this idea?

Use extract_idea_landscape with idea "procurement intelligence saas"

Returns funding signal, pain signal, crowding signal, market signal, ecosystem signal, and launch signal — all timestamped.

Full company intelligence in one call:

Use extract_company_landscape with company "Palantir" and ticker "PLTR"

SEC filings + federal contracts + global news + changelog + market data.

Did that company just disclose something material?

Use extract_sec_filings with url "Palantir Technologies"

8-K filings are legally mandated within 4 business days of any material event — CEO change, acquisition, breach, major contract.

Is this dependency still actively maintained?

Use extract_changelog with url "https://github.com/org/repo"

Returns the last 8 releases with exact dates. If the last release was 18 months ago, you'll know before you pin the version.

Deployment & infrastructure

The reference implementation runs on Cloudflare's global edge:

• D1 database — 18 watched queries running on 6-hour cron with relevancy scoring
• KV-backed rate limiting — 60 req/min per IP across all edge nodes
• Defensive valves — clock-skew rejection (5min tolerance), hard floor at R_t<5, lazy decay at read time
• Provenance — Ha-Pri v1 SHA-256 provenance stamps on stored signals; hard tamper enforcement is a future Ha-Pri v2 path
• Schema migrations — promise-gated, idempotent, run on first request after deploy

Production: https://freshcontext-mcp.gimmanuel73.workers.dev

---
