Extcord MCP server

• Registry nameio.extcord/extcordverified in the MCP registry

The registry name sits under extcord.io. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-27 the server answered initialize and tools/list without a sign-in. First answer in 57 ms.

• Whether its tools do the product's job has not been judged yet.
• Checked on 1 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• read_page

  Fetch a public web page and return only the part you need instead of the raw HTML. view: markdown (main content, navigation and boilerplate removed), outline (headings), links (all links; query keeps those whose URL or text contains it)…

• calculate_expression

  Evaluate an arithmetic expression exactly: + - * / // % ** use rational numbers, not floats, so 0.1 + 0.2 = 0.3, and money strings like "$1,200.50" read as numbers. Roots, logs and exp are computed to 50 significant digits (returned in…

• calculate_date

  Get the current date and time, or do calendar math exactly, DST-aware. action=now: the current time in tz. action=add: shifts date by the add object, e.g. {"months": 1} or {"business_days": 10}; month ends are clamped (Jan 31 + 1 month =…

• read_package_info

  Get a package's latest release from PyPI, npm or crates.io as a few fields (version, license, summary, links and the registry's requirement or download fields) instead of the registry's raw response. Latest release only: there is no…

• discover_ops

  Find the op or recipe for a job, or read the details of one. query: best-matching ops, led by solved_before (recipes other agents already proved, with their success rate). op: that op's full contract (args schema, behavior, worked…

• run_op

  Run one of the 43 ops by id: returns the value, or for large results a preview and a handle id (h_...) to pass as the next op's input. Ops by category: data: json_parse, get, filter, pick, pluck, sort, unique, count_by, stats; format…

• run_pipeline

  Chain ops in one call: each step is {op, input?, args?, as?, input_type?}, later steps refer to earlier results as "$0", "$name" or paths like "$1[0]", and only the final result comes back while intermediate data stays on the server. Use…

• read_handle

  Read a stored result (handle) without running anything: view=summary for its type, size, est_tokens and suggested next ops; view=value for the data itself one page at a time (follow next_offset); view=provenance for the ops, args and…

• run_recipe

  Run a saved recipe (a named, parameterized pipeline, built in or published by agents) in one call; its result is checked against the recipe's expectations. version runs an earlier version from its history, checked against that version's…

• save_recipe

  Publish a pipeline that worked as a public recipe any agent can run with run_recipe, or publish a new version of one you saved before (pass its edit_key). With an example, the recipe is run once (this fetches live pages, counting toward…

• delete_recipe

  Permanently delete a recipe you saved, with its version history and track record, using the edit_key from its first save. Use this to withdraw a recipe that's wrong or no longer needed; to change one, publish a new version with…
